FIELD: transport engineering. ^ SUBSTANCE: invention can be used in brake systems of trolleybuses, automobiles, tractors and other vehicles with electric transmission. Proposed brake system contains supply sources, relay valve, brake chambers, electronic control unit coupled with traction electric motor and brake pedal position pickup, and brake cock whose first section is connected with control input of relay valve. Supply source is connected with power input of relay valve, output of relay valve is coupled with rear brake chambers. Novelty is that system contains additionally pressure modulators, brake torque pickups and antilock system control unit. Output of relay valve is successively connected with pressure modulators and brake chambers of rear wheels. Output of second section of brake cock is successively connected with pressure modulators and brake chambers of front wheels. Antilock system control unit is coupled with electronic control unit, pressure modulators and brake torque pickups. ^ EFFECT: increased efficiency of braking, stability and steerability of vehicle at simultaneous application of pneumatic brakes and traction motor braking. ^ 1 dwg |
