FIELD: transport.SUBSTANCE: device comprises drum-type shoe brakes of rear drive wheels and common brake drive. Common brake drive comprises drive levers, rollers, brake cables, equaliser, tie rod, lever with release spring, control cable, control handle with rack and latch. Every brake incorporates individual brake drive. The latter comprises control bell crank with return spring and ratchet-and-pawl gear fitted on horizontal shaft and cylindrical washers rigidly fitted on brake cable ahead of control lever lower end and equaliser. Brake cable passes unobstructed through equaliser end hole and control lever bottom end hole. Cylindrical holes for brake cables in balancer and control levers in the front part have cylindrical recessions into which cylindrical washers with chamfers from the side of these recessions enter.EFFECT: possibility of temporary use of parking brake system, higher device reliability due to enhancement of couplings.2 dwg |
