Abstract

The invention relates to testing equipment for stress of car hubs, in particular to testing equipment for alternating stress bending of the car hubs. According to the specific technical scheme, the testing equipment comprises a rack seat and a rack box; the rack box is mounted on the rack seat, and a lifting mechanism, a force application wheel hammer mechanism, a hub support mechanism and an anti-explosion safety structure are sequentially mounted on and in the rack box from top to bottom. The testing equipment has the advantages that complete analogue simulation testing is achieved, and the equipment operation is durable, safe and reliable; alternating stamping force can be adjusted within a wide range; stress is balanced, and the phenomenon that the equipment is jammed after being used for a long time is avoided; the testing equipment is suitable for stress tests of all the car hubs, and the testing range is wide; the rotating speed of the testing equipment can be selected and regulated according to the stress requirement of the hubs of different specifications to obtain corresponding impact force; the strength of the hubs can quantitatively guide manufacturing rather than quantitatively, and new promotion force is brought to the industry.

Description

technical field [0001] The invention relates to a force testing device for a vehicle wheel hub, in particular to a test device for bending a vehicle wheel hub under alternating force. Background technique [0002] With the development of society, vehicles have become the main means of travel for people, and the safety performance of vehicles is closely related to the safety of personal life. As the main part of the vehicle, the hub bears all the gravity of the vehicle, various impact forces during travel and bending force when turning. When the vehicle turns, the hub will be subjected to bending force. This force is an alternating state. The force of this alternating state will lead to deformation, sudden fracture and fatigue fracture of the hub. Once the wheel hub is damaged, the vehicle will lose control and easily cause traffic accidents. [0003] Existing test equipment for wheel hub stress bending can generally only test the static force condition of the wheel hub, an...
