PNEUMATIC DRIVE OF THE SERVICE BRAKE SYSTEM OF THE VEHICLE Russian patent published in 2022 - IPC B60T8/00 B60T13/26 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering, namely to braking devices of vehicles. The pneumatic drive of the working braking system of the vehicle contains a compressor from which compressed air enters the air preparation unit through the oil trap, where it is cleaned and divided into independent circuits of the brake mechanisms of the front wheels and wheels of the rear axles, arriving at the brake circuit mechanisms, including receivers, anti-lock system modulators, brake chambers, accelerator valves; the two-section brake valve, which, when braking, passes air from the cylinders into the actuators of the brake circuits of the front, middle and rear axles, and the brake circuit mechanisms of the front wheels and each axis of the circuit of the wheels of the rear axles contain valve devices with two control ports assembled with two-line valve devices, as well as using receivers of the front axle and rear axles of a vehicle with the same volume of compressed air.

EFFECT: achievement of the full realization of the adhesion weight during braking, the minimum consumption of pneumatic energy during the operation of the anti-lock brake system, the optimal distribution of energy between the circuits when the compressor fails, the improvement of road holding on roads with a low coefficient of friction.
