Bosch push belt Continuously variable transmissions on the rise worldwide

  • An easier drive consuming up to 7 percent less fuel thanks to continuously variable transmissions
  • One quarter of all automatics will soon feature continuously variable transmissions
  • Bosch technology is suitable for vehicles with up to 450 Newton meters of torque and more than 300 horsepower (220 kilowatts)
Driving up a winding mountain road can be a tiresome task. None of the gears seems to be right. Sometimes they are too high, sometimes too low. With continuously variable transmission, it's a different story. As its name suggests, this automatic transmission works without any fixed shifting point. The result is a smooth drive at constant traction and engine speed.

“With its smooth and dynamic acceleration, continuously variable transmission makes driving easy and enjoyable,” says Stefan Seiberth, the president of the Bosch Gasoline Systems division. “CVT especially comes into its own in urban stop-and-go traffic. It can reduce fuel consumption by as much as 7 percent, since the engine is constantly kept at its most efficient operating point.” Bosch manufactures the push belts that are a central component of CVT. They make it possible for the transmission to drive engines with a torque range between 60 and 450 Newton meters and an output of more than 300 horsepower (220 kilowatts). Using an electronic control, a number of different settings are possible, from economical to sporty.

In addition, the continuously variable transmission is extremely compact, since it comprises just a few components. The control unit, for example, can be integrated directly into the system. The compact construction keeps the manufacturing cost down, and also means that this transmission fits into small urban vehicles. This also explains why CVT is especially popular in Japan. However, its market share is also growing in China and North America. Currently, every fifth automatic in the world is equipped with CVT. In just a few years, this share will grow to one-quarter. The technology is currently available in some 300 production models.

Flexible, yet as rigid as a solid steel rod
Bosch is also benefiting from this increase in market share. In 2012, the automotive supplier manufactured its 25 millionth CVT push belt. The component comprises hundreds of specially punched steel elements, stacked together in a high-alloy steel ring package. This design makes the push belt very flexible, but at the same time as rigid as a solid steel rod. This means that the Bosch component is very adaptable. It does not have to be developed separately for each vehicle, but often requires some adjustment only.

The way a CVT works is always the same. It closely resembles a set of bicycle gears: when the transmission ratio is higher, the diameter of the belt is larger on the drive shaft and smaller on the driven shaft. When the transmission ratio is lower, the situation is reversed, with a smaller belt diameter on the drive shaft and a larger one on the driven shaft. This stepless adjustment is made possible by the movement of the push belt. On both the drive and driven shaft, it moves between two cones that face each other. Depending on engine speed and torque, these pairs of cones alter the diameter traveled by the belt. In this way, there is always an optimum balance between required torque and engine speed.

Continuously variable transmissions are equally suitable for diesel, gasoline, and hybrid powertrains. And while this technology saves fuel in classic internal-combustion engines, it can also increase hybrid powertrains' electric range. This is because the CVT allows the internal-combustion engine to run at a higher speed, close to the optimum operating point. As a result, part of the energy released can be used for forward propulsion, while the rest can be stored in the rechargeable battery.

Annual Press Conference 2014 Bosch registers double-digit growth in China Continuous innovation and localization efforts

  • Consolidated sales increase of 18 percent to a total of CNY 41.2 billion (5 billion euros)
  • Pioneering innovations for a connected world
  • Energy-saving and emissions-reducing efforts for local sustainable development
  • Double-digit growth expected again in 2014
Beijing – Bosch, a leading global supplier of technology and services, recorded consolidated sales of CNY 41.2 billion* (5 billion euros) in China in 2013 – a significant year-on-year growth of 18 percent. “This outstanding performance demonstrates the lasting strength and success of our innovative technologies and localized solutions for the Chinese market,” said Peter Tyroller, the member of the board of management of Robert Bosch GmbH responsible for Asia Pacific. He added: “China expects to witness further stable economic growth, which will ensure a healthy business environment with dynamic opportunities. We aim to further strengthen our position in China, and we strive to achieve double-digit growth in the years to come as well.”

Bosch’s Automotive Technology business sector grew almost twice as fast as the market in China in 2013. Sales development of Bosch’s other three business sectors in China reflects the development of the respective industries in the past year. Power Tools, part of Bosch’s Consumer Goods business sector, reports moderate sales revenue growth. In the Energy and Building Technology business sector, the Thermotechnology division performed well thanks to its expanded portfolio and energy-efficient condensing appliances, while the Security Systems division experienced a slight decrease. In the Industrial Technology business sector, the Drive and Control Technology division has not yet fully recovered: however, there are signs that the construction market is stabilizing. The Packaging Technology division achieved moderate growth.

Continuous localization efforts
Bosch continues to intensify its localization strategy in its various business operations. In the last three years, Bosch has invested over CNY 10 billion in China, with the aim of further enhancing its local value chain, and especially of cultivating local R&D competence. In the past year for example, Bosch’s Automotive Aftermarket and Chassis System divisions opened plants in Nanjing and Chengdu respectively, and a new Automotive Test and Technology Center in Donghai. This year, the Bosch joint venture Bosch Mahle Turbo Systems plans to open a plant in Shanghai for the production of turbochargers for gasoline engines. There are also plans for a plant for diesel systems in Qingdao.

Bosch currently has a total of 17 technical centers in China. The number of Chinese associates working in R&D increased to 3,300 – more than 10 percent of Bosch’s total headcount in China. The more than 150 patents filed in China last year – nearly 20 percent more than in the previous year – are a sign of Bosch’s increasing local R&D competence. “We are focusing on affordable products, especially in the mid-price segment, which are tailored to local customer needs without compromising Bosch quality,” said Dr. Chen Yudong, president of Bosch (China) Investment Ltd. As an example, Bosch Thermotechnology launched its first series of air-source heat pump water heaters in China in March this year. These take account of specific local needs for relatively small volumes of 150 and 200 liters, as well as of energy-saving requirements.

Associates as cornerstone of business development
By the end of 2013, Bosch had increased its workforce in China to over 32,000. Two-thirds of its local management team are Chinese. Bosch offers a comprehensive incentive package with diverse associate training programs. In 2013, Bosch Training Center offered over 900 training sessions. As a result of these efforts, Bosch has now been named “Top Employer” by the Corporate Research Foundation, an independent international human resource institute, for three years running. “Our dedicated associates are our great strength and I would like to give credit to them for Bosch’s business success in 2013,” said Dr. Chen Yudong. “It is their hard work and innovative ideas which make our success possible. The innovations provided by our talented associates will continue to be a main driver of our future success.”

Pioneering innovations for a connected world
Bosch estimates more than 75 percent of the global population and 6.6 billion devices will be connected to the internet by 2015, which will bring more convenience in daily life and significantly improve energy efficiency. In line with this trend, Bosch is reaching out to new business areas and promoting new business models, especially by leveraging and combining its wide-ranging expertise in existing areas of business. “The internet of things and services is now a hot topic in China, and we expect stronger momentum in the coming years. As an innovative company, Bosch is ready for the business opportunities it brings us,” said Dr. Chen Yudong.

Leveraging its sensor and software technologies, Bosch is sparing no effort to establish the framework and foundations of connectivity. Bosch Sensortec, the Bosch subsidiary that specializes in MEMS (micro-electro-mechanical systems) technology, has had its Asia Pacific headquarters in Shanghai since 2013. Bosch Sensortec develops and markets micro-mechanical sensors for consumer electronics, mobile phones, safety systems, industrial technology, and logistics. Now every second smartphone worldwide uses Bosch sensors. While MEMS technologies are regarded as the hardware basis for connectivity, Bosch Software Innovations is capable of providing software solutions. It launched a pilot project for promoting electric vehicle application in Shanghai in 2013. Automated driving is another example of the potential and advantages of connectivity technologies. With connectivity-capable components such as sensors, cameras, and electronic control units, Bosch can offer driving assistance functions which will lead to automated driving in the future.

Energy-saving and emissions-reducing efforts for sustainable development
In China, rapid industrialization and urbanization create enormous challenges for the environment, and make immediate energy-saving and emissions-reducing efforts necessary. Stricter environmental protection regulations already show the government’s determination to tackle these challenges. “The fastest way to get results is by improving the efficiency of energy conversion. Bosch offers innovative technical solutions for energy efficiency, ranging from mobility to home appliances”, Peter Tyroller said. For example, on the path to electrification, Bosch’s aim for 2020 is to reduce the fuel consumption of gasoline- and diesel-powered vehicles by a further 20 percent from their 2012 levels. Bosch’s Thermotechnology division has also successfully developed a condensing wall-mounted boiler with thermal efficiency of as much as 111 percent.

As a sustainable manufacturer, Bosch has introduced its EHS (environment, health, and safety) standards in all its manufacturing sites in China, especially for energy saving, resource conservation, and pollution prevention. Thanks to the joint efforts of 150 fully dedicated associates involved in supervising and controlling work across China, Bosch China reduced its relative energy consumption by almost 24 percent and relative CO2 emissions by 21 percent across China in 2013, compared with their 2007 levels.

Auto China 2014 Bosch shapes the future of electric, automated, and connected driving Global innovations pave the way for sustainable development of Chinese automotive industry

  • Higher environmental and safety needs driving innovations in powertrain and automated driving technologies
  • Connected driving: safety, comfort, and convenience
  • Continuous localization efforts ensure double-digit growth of Bosch automotive business in China
Beijing – Bosch, a leading global supplier of automotive technology and services, is bringing its latest automotive technologies to the 13th Beijing International Automotive Exhibition (Auto China 2014). Focusing on electrification, automation, and connectivity, Bosch is presenting a series of future-oriented automotive technologies and solutions to meet Chinese users’ increasing needs for cleaner, safer, more efficient, and more comfortable driving experiences.

“The global automotive industry is going through a profound technological revolution, and China will be an important part of it,” said Wolf-Henning Scheider, the board of management member of Robert Bosch GmbH responsible for the company’s global automotive business. “To keep up with the trend of electric, automated, and connected driving, Bosch has developed a comprehensive portfolio of automotive technologies in these three areas. And our continuous innovations help us stay at the forefront of the industry.”

Environmental and safety regulations are shaping the future of mobility
Globally, ever-stricter regulations for fuel consumption, emissions control, as well as road safety are driving the development of powertrain and automated driving technologies. “There is still considerable potential in internal-combustion engines, if various measures are taken,” Scheider explained. “By 2020, the fuel consumption of gasoline- and diesel-powered vehicles can be further reduced by another 20 percent from its 2012 level.” Improved injection and engine management systems, turbocharged downsized engines, as well as start-stop and regenerative braking systems are some of the solutions to increase the efficiency of cars with internal combustion engines. They are all on display at the Bosch booth.

Besides improving the conventional powertrain, electrification will play an increasingly important role in the future of mobility, especially to help reduce air pollution in large cities and to aid in resource conservation. “Our portfolio of electric solutions encompasses a broad spectrum from e-bikes and e-scooters, through mild and plug-in hybrids, all the way to fully-electric powertrains,” Scheider said. “With varying levels of electrification depending on the vehicle class, Bosch is dedicated to helping China reach its stricter fuel-efficiency targets and emission standards.”

For instance, in combining the four efficient functions of recuperation, boosting, start-stop, and coasting, the boost recuperation system (BRS) can lower fuel consumption and CO2 emissions up to 15 percent. Another revolutionary new powertrain technology is the hydraulic hybrid, which features a pressure accumulator filled with nitrogen which stores deceleration energy, as well as a hydraulic motor which converts accumulated energy into propulsion. On average, the system reduces fuel consumption by 30 percent, or even up to 45 percent in city driving with frequent acceleration and breaking.

Road accidents have become one of the primary causes of injury and death. Around 60,000 people die in road accidents each year in China and a majority of traffic accidents are caused by human error. As the first supplier testing automated driving on German roads, Bosch continuously invests in developing automated safety and assistance functions, and is committed to the future of accident-free driving. Today, more than 5,000 engineers at Bosch are developing more powerful safety and assistance systems which form the basis for automated driving. In China, advanced driver-assistance systems are being marketed and increasingly installed in vehicles produced by Chinese automakers. Moreover, the Bosch iBooster is a pioneering braking solution for hybrid and electric vehicles. It is an electromechanical brake booster that doesn’t require a vacuum, but effectively provides braking assistance and allows almost all the energy lost in typical braking to be recovered.

Connected driving: safety, comfort, and convenience
To achieve the vision of fully automated driving, vehicle connectivity is one of the prerequisites. “Fully automated driving will be possible only with connected driving. For it to work, at least 50 percent of the vehicles in flowing traffic have to be sharing data with each other in real time.” explained Scheider. “The aim of vehicle connectivity is accident-free, comfortable, and informed driving, as well as the convenience of an increased range of services for users.” By 2025, Bosch expects that almost all newly-registered vehicles will be “connected” and share data with each other in traffic.

One of the solutions Bosch offers in this field is the new connectivity control unit (CCU). For an efficient fleet management, the CCU helps to monitor vehicles and analyze their condition. Another example is Bosch mySPIN, which features a system for integrating smart phones into the vehicle. Compatible with both IOS and Android operating systems, mySPIN enables smart phone apps to be operated on the dashboard display exactly as they are on the phone. This means they can be used safely while driving, thus increasing comfort and safety.

Increasing localization for sustainable development in China
“Thanks to long-term cooperation with local car makers, Bosch has been increasing localization, particularly in research and development as well as manufacturing,” said Dr. Xu Daquan, the executive vice president of Bosch (China) Investment Ltd. “We will continue to work with our partners in China closely and support them by providing innovative automotive solutions and services.” Thanks to its product excellence and close partnerships, Bosch China received a total of over 40 excellent supplier awards from more than 20 original equipment manufacturers (OEM) in 2013.

Over the last five years, Bosch’s automotive business in China registered a compound annual growth rate of 17 percent, achieving sales of CNY 32 billion in 2013. In addition, three new automotive operations were inaugurated in China last year, involving a total investment of around CNY 2.5 billion. By the end of 2013, Bosch China had established 26 automotive manufacturing sites, 11 automotive technical centers, two automotive test centers, and over 1,600 Bosch Car Service workshops.
