Description

Technical Field

[0001] The utility model relates to the technical field of automobile component testing, in particular to a steering knuckle impact testing device. Background Art

[0002] The steering knuckle is an important component of the automobile suspension system. It connects the wheel hub and the suspension control arm. It is also the mounting carrier of the steering knuckle arm and the brake caliper. It bears the front load of the car, supports and drives the front wheel to rotate around the kingpin to steer the car, ensures the stable driving of the car and sensitively transmits the driving direction. When the car is driving, it is subjected to complex and changeable load conditions. Therefore, it requires greater rigidity and sufficient strength and safety factor; at the same time, the mass should be reduced as much as possible to meet the requirements of handling stability and vehicle lightweighting. Therefore, it is necessary to perform an impact test on the steering knuckle. At present, most of the test devices on the market cannot meet the requirements of changing a certain height or position according to the needs of the user, and the service life of the device will also be affected due to frequent impact. For this reason, we propose a steering knuckle impact test device. Utility Model Content
