VEHICLE BRAKING DEVICE (VERSIONS) Russian patent published in 2010 - IPC B61H7/00 B60T8/32 F16D41/02 

FIELD: transport.

SUBSTANCE: proposed device intended primarily for emergent and service braking comprises spring-suspended brakes with friction amplifier fitted on wheel pair axles. Servo drive of every brake comprises: reference voltage generator common for all brakes with potentiometre, wheel pair rotation deceleration pickup, comparator unit, amplification and motor actuator unit coupled with brake control mechanism representing a screw pair. Vehicle braking device intended primarily for downhill braking is made similarly to emergent and service braking device except for wheel pair deceleration pickup replaced by wheel pair rpm pickup.

EFFECT: shorter braking distance, better control and simple transfer of control force to brakes.
