chamber 3 Base valve Advantages: Insensitive to stone throw. Tube can be adapted to fit in locations where space is limited. This shock-absorber type is short, as the balance chamber is next to the working cylinder. [Bosch, 2007] Behzad Samadi (Amirkabir University) Industrial Control 5 / 86
spring 3 Accumulator 4 Gas volume 5 Rubber diaphragm 6 Fluid 7 Hose 8 Shock absorber System reacts to increased vehicle speed by reducing body ride height, resulting in fuel savings Increase in vehicle-body ride height on poor road surfaces Enhanced stability in curves achieved through lateral blocking of the suspension elements on a given axle [Bosch, 2007] Behzad Samadi (Amirkabir University) Industrial Control 9 / 86
is altered to correspond to the vehicle’s load by means of a mechanical device which transmits the relative movement between axle and vehicle body to the step-bore piston in the valve. The force acting on the step-bore piston during braking is again modified by the dynamic axle load transfer and thus influences the braking force on the rear axle. This guarantees maximum deceleration while at the same time largely preventing locking of the rear axle and the resulting danger of skidding. conti-online.com Behzad Samadi (Amirkabir University) Industrial Control 34 / 86
more tolerant to small leaks. The smallest leak in a hydraulic system could result in brake failure. An air brake system includes a compressor to generate more compressed air as needed. icbc.com Behzad Samadi (Amirkabir University) Industrial Control 36 / 86
