Description

Technical Field

[0001] The utility model relates to the field of detection devices, and particularly relates to a V-type thrust rod torsional fatigue detection device. Background Art

[0002] The V-type thrust rod generally consists of three parts: a large ball pin, a V-type rod body, and a small ball pin. The ball pin is mainly composed of a metal core shaft and an elastomer. During operation, the core shaft can move radially / axially, rotate, and swing. As a key force transmission component of a commercial vehicle suspension, the V-type thrust rod assembly is mainly used to keep the axle position relatively fixed and transmit longitudinal and lateral forces. At the same time, it can also transmit forces and torques in other directions to ensure a definite motion relationship between the wheel and the vehicle body. As one of the key components of the vehicle suspension, the V-type thrust rod not only significantly improves the load-bearing capacity of the vehicle but also greatly enhances the lateral stability of the vehicle.

[0003] During the vehicle driving process, the V-type thrust rod will be subjected to alternating loads such as longitudinal tension / compression, lateral tension / compression, torsional force, and deflection force, and has extremely high reliability requirements. Patent CN 220356833 U discloses a V-type thrust rod assembly inspection tool, including an operation table, a support block fixedly connected to the top of the operation table, a first motor fixedly connected to the side wall of the support block, a lead screw fixedly connected to the output end of the first motor, one end of the lead screw passing through the support block, a first slider threadedly connected to the side wall of the lead screw far from the motor, connecting rods symmetrically fixedly connected to the side wall of the first slider, and connecting plates symmetrically fixedly connected to the side wall of the first slider, but it can only perform compressive tests on the V-type thrust rod, with a single function.

[0004] Therefore, it is particularly important to urgently design a V-type thrust rod torsional fatigue detection device to solve the above defects. Summary of the Utility Model
