Driveline Technology and Chassis Technologie

ZF Technology in Passenger Cars

Innovations of Great value

Automobiles also move people in an emotional way. This fascination goes beyond eye-catching designs and high-performance engines. Attention is also focused on intelligent concepts that combine future mobility and driving enjoyment with lower fuel consumption, environmental protection and improved safety features. These characteristics are anything but contradictory for ZF. In the world of driveline and chassis technology, ZF has been setting the standards for decades. As a reliable partner for car manufacturers, the focus at ZF is on making cars more agile, safer and more efficient.

SACHS has the ideal clutch to suit just about every vehicle in accordance with OEM regulations. Technically perfect and tried and tested thousands of times. And no need to mention that the linings are asbestos-free. The service life of the individual clutch components is just about equal nowadays. For this reason, SACHS offers a programme with complete kits as the optimum solution to meet spare requirements.

With respect to safety, shock absorbers have the job of preventing the wheels from „hopping“ on uneven surfaces and thus being unable to transmit braking, traction, or lateral forces when they temporarily lose contact with the road. Suspension comfort suffers when chassis movements caused by driving over uneven surfaces, changing directions, braking, and accelerating are transmitted "unfiltered", so to speak, to the passengers. Shock absorbers substantially reduce this effect and thus contribute substantially to passenger comfort. Moreover, hopping wheels and strong chassis vibrations due to improperly functioning shock absorbers lead to increased wear on the tires and chassis components.

Rack and pinion power steering with variable ratios is used in many applications. It is as equally suitable for mid-size sedans and light commercial vehicles as it is for sports cars. It enables precise and rapid steering responses at higher speeds without excessive or jittery over-reaction to minor steering adjustments. It optimizes the handling of the vehicle when manoeuvring it in or out of a parking space, when turning around in tight spaces or during extreme cornering. Depending on the manufacturer’s specifications, the rack and pinion power steering may also be fitted with a number of equipment options. At the OEM level, this allows the steering to be adapted in an optimum way to the kinematic and motorization conditions present on the vehicle.

Steering and suspension components are safety parts which are designed, made and assembled with particular care. They must provide an ultimate level of safety in all driving situations which can occur either influenced by the driver or not. The status "D-part" (safety component) requires an extensive array of different tests to be documented in detail.

Rubber-to-metal components are indispensable construction elements, which not only directly influence driving performance, but also take over other functions. Gearbox and engine bearings connect the transmission and the engine to the chassis. At the same time, they dampen vibrations and eliminate noises such as bucking, engine sounds, reactions to load change, car body drum and transmission noises.

Although clutch facings have undergone substantial improvement in terms of quality and service life, they are still subject to normal wear, even if the vehicle is operated with care. Reduced facing thickness considerably influences the forces within the clutch system. Release and clamp loads rise, and thus the necessary pedal forces as well. XTend is the ideal solution to counter wear and the associated negative effects on the powertrain. XTend clutch covers are suitable for all vehicles with high mileage and clutch loads.
