METHOD OF PARKING BRAKE OPERATION AT ORIGINATION OF FAULT AND PARKING BRAKE MODULE TO THIS END Russian patent published in 2014 - IPC B60T13/36 B60T13/68 B60T17/02 B60T17/18 

FIELD: transport.

SUBSTANCE: set of invention relates to automotive industry, particularly, to parking brakes. In the case of fault, operation of parking brake partially integrated in compressed air preparation module consists in setting pressure in said module higher than normal one. Continuous compressed air feed is shut off. Decreased pressure is set whereat said module is disconnected to decrease pressure therein by multiple operation of acceleration vale to level whereat said disconnection is effected. Parking brake module comprises electronic control device, set of solenoid valves and acceleration valve taking up the control pressure to feed air into brake cylinder with spring power accumulator and to release its therefrom. Said electronic control device serves to detect undesirable overpressure, to shut off continuous feed of compressed air and to decrease pressure level inside parking brake module.

EFFECT: simplified design.
