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.
