Abstract

The embodiment of the invention discloses a half clasp fatigue test assembly and a fatigue test device. In the half snap ring fatigue test assembly, one end of the fixed seat is provided with a hollow structure, which is used to support the half snap ring sample and limit the axial movement of the half snap ring sample; There are pin holes, grooves are set on the hypotenuse surface, and bosses are arranged in the grooves, the two sides of the grooves are used to engage and fix one end of the half snap ring sample card, and the bosses are used to assemble with the pull plate Apply load to the half clasp sample; one end of the tie rod is set as a double lug structure, and the front end of the double lug structure is provided with a pin hole, the double lug structure of the tie rod penetrates into the hollow structure of the fixed seat, and the pull block is engaged In the hollow area of ​​the double lug structure, the positioning pin is passed through the pin hole of the double lug structure and the pin hole of the pull block. The embodiment of the present invention solves the existing problems of verifying the fatigue life of the half snap ring, such as huge manufacturing cost and too long test period.

Description

technical field [0001] The present application relates to but not limited to the technical field of brake wheel testing, in particular to a half clasp fatigue testing assembly and a fatigue testing device. Background technique [0002] The half snap ring of the brake wheel is a component part of the single web wheel, which is installed in the snap ring groove of the wheel hub, and its function is to prevent the movable wheel rim from falling off from the wheel hub. The half snap ring bears the external expansion force after the tire is inflated, the applied force of the vertical load and the reaction force of the hub to the half snap ring. During the rolling process of the wheel, the half snap ring bears alternating loads. The failure mode of the half snap ring during use is fatigue fracture. Since the function of the half snap ring is to prevent the movable rim from falling off from the hub, once the half snap ring fails, the rim and the tire will come off the hub, causing...
