Description

Technical Field

[0001] The invention relates to the field of detection devices, and in particular to a two-degree-of-freedom fatigue detection device for a V-shaped thrust rod. Background Art

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

[0003] The V-type thrust rod will be subjected to the alternating effects of loads such as longitudinal tension / pressure, lateral tension / pressure, torsion and deflection during vehicle driving, and the reliability requirements are extremely high.
