Automatic stamping dies for beam joints used in high-performance tripod constant velocity joints

Abstract

The invention discloses a high-performance tripod constant velocity universal joint comprising a three-column housing and a dust-proofing rubber sleeve sleeved on the circumference of the end of the three-column housing. A tripod is arranged inside the three-column housing and comprises a spider and a roller. Three pins are distributed on the circumference of the spider evenly, the circumferential surface of the spider among the three pins is free of central positioning hole. According to the high-performance tripod constant velocity universal joint, using performances of the tripod constant velocity universal joint are improved through structures of a drew-string type clamp, which is formed in a highly automated manner, with segments and no central positioning holes on the circumferential surface of the spider among the three pins, and manufacture of the high-performance tripod constant velocity universal joint is realized by adopting an automatic indexing chuck structure.

Description

technical field [0001] The invention relates to a universal joint, in particular to an automatic stamping die for a beam joint used in a high-performance tripod constant velocity universal joint. Background technique [0002] Modern cars generally adopt front-wheel drive, and the speed of driving is very fast, and the driving is required to be stable. Therefore, the transmission shaft between the car differential and the two front wheels must be composed of constant velocity universal joints. Triple-pin constant velocity joints are especially commonly used in constant velocity joints. The tripod in the tripod constant velocity universal joint is the key core component. The tripod includes the tripod frame and the roller. The current tripod frame realizes the tripod on the tripod frame by processing the center hole on the circumference. The trisection of the three pin shafts (the angle between the three pin shafts is 120°±10') and the grinding shaft diameter, this process r...

Problems solved by technology

The tripod in the tripod constant velocity universal joint is the key core component. The tripod includes the tripod frame and the roller. The current tripod frame realizes the tripod on the tripod frame by processing the center hole on the circumference. The trisection of the three pin shafts (the angle between the three pin shafts is 120°±10') and the grinding shaft diameter, this process retains the process center hole, and from the perspective of the performance of the entire product, the process center hole It is easy to cause the tripod to break due to excessive stress concentration and make the whole product invalid, and the service life is relatively short. How to overcome the process center hole structure to improve the service life of the tripod has always been the research of those skilled in the art. Object

This kind of universal joint does not mention the technical improvement or technical tips of the three-ball pin and the head of the clamp
