Abstract

The invention discloses a fatigue test device for an automobile manual braking operating mechanism, comprising a machine rack, a fatigue test mechanical unit, a pneumatic part and an electric control part; the fatigue test mechanical unit comprises a horizontal support plate fixedly connected with the machine rack, a specimen mounting bracket on the upper surface of the support plate, and a pulley mechanism; the pulley mechanism comprises a first fixed pulley, a second fixed pulley and a movable pulley; the first fixed pulley is arranged at the top end of one side of the machine rack; the second fixed pulley is arranged at the other side of the machine rack; one end of a wire rope is fixed on the machine rack, while the other end is connected with a balancing weight; and the wire rope is sequentially threaded through the movable pulley, the second fixed pulley and the first fixed pulley. With such a structure, the fatigue test device of the automobile manual braking operating mechanism achieves lightweight of test load balancing weight and is easy to operate during the test; besides, the fatigue test device does not need lifting equipment and can reduce the size of the machine rack to improve the utilization rate of the rack.

Description

technical field [0001] The invention relates to test equipment, in particular to a fatigue test device for an automobile hand brake operating mechanism. Background technique [0002] Automobile hand brake operating mechanism needs a fatigue test device that simulates actual working conditions. The existing fatigue test device for automobile hand brake operating mechanism includes a frame, a fatigue test mechanical unit and an electronic control unit. The fatigue test mechanical unit includes a A fixed horizontal support plate, a fixed specimen mounting bracket on the upper surface of the support plate, a pulley mechanism, and two cylinders with intersecting axes. The pulley mechanism includes a fixed pulley, a steel cable passing through the fixed pulley, and one end of the cable is connected to The counterweight, the other end of the steel cable is connected with the specimen mounting bracket. Such structure, the weight of counterweight is heavier, needs to use hoisting eq...
