Broad product range for commercial vehicles with focus on rear-axle steering systems and attachment parts

  • 144 new part numbers: commercial-vehicle steering systems and attachment parts perfectly geared to the respective vehicle model
  • Spare parts for preventive maintenance increase the vehicle safety and its operational readiness
  • Production in line with original-equipment quality standards
  • Expanded range increases the vehicle coverage

Schwäbisch Gmünd – Especially in case of special vehicles with numerous axles and heavy superstructures or vehicles carrying particularly heavy loads, the rear-axle steering systems are often subject to heavy strains. Depending on their operating environment, they may also feature an increased risk of damage. This is the case with fuel tankers, dump trucks or garbage trucks. It is thus highly recommended to check the components regularly and replace them on time if required. In order to ensure the highest possible vehicle safety and quick replacement right on the vehicle, Bosch now expanded its range of rear-axle steering systems and attachment parts for commercial vehicles by additional 144 new part numbers. The expanded portfolio includes spare-part components such as operating cylinders, ball joints, oil reservoir, hydraulic accumulators, flow limiter valves, Pitman arms, valves and flow indicators.

Operating principle of rear-axle steering systems

Hydraulic rear-axle steering systems (Rear Axle Steering or RAS) are steering systems for commercial vehicles hydrostatically transferring the steering move-ment applied onto the front axle to the rear axle. In case of RAS, this hydrostatic transfer occurs by means of a master cylinder at the front axle, hydraulic lines and a centering cylinder at the rear axle. At electronically controlled rear-axle steering systems (RAS-EC), an electronic control unit operates a hydraulic control valve steering the rear axle by means of a centering cylinder.

Compared to pure front-axle steering, rear axle steering systems feature a num¬ber of advantages such as improved driving dynamics, a reduced turning radius and reduced tire wear. Thanks to their compact design and low diversity of parts, rear-axle steering systems are also easy to maintain.

High quality standards and global availability

In case of vehicle components as safety-relevant as steering systems and matching attachment parts, high quality matters. Bosch thus also emphasizes on the OE quality of its commercial-vehicle steering-system spare parts for work¬shop demands. In addition, each and every one of these components is specifi¬cally geared to the respective vehicle. Thanks to stock production and product availability in more than 80 countries, these spare parts can be delivered quickly. This reduces expensive idle times of commercial vehicles in need of repair.

The Automotive Aftermarket division (AA) provides the aftermarket and repair shops worldwide with modern diagnostic and repair shop equipment and a wide range of spare parts – from new and exchange parts to repair solutions – for passenger cars and commercial vehicles. Its product portfolio includes products made as Bosch original equipment, as well as aftermarket products and services developed and manufactured in-house. About 17,000 associates in more than 150 countries, as well as a global logistics network, ensure that spare parts reach customers quickly and on time. AA supplies testing and repair-shop technology, diagnostic software, service training, and information services.
