Locking force adjustable separated full-contact bearing support special for constant-velocity universal joint assembly

Abstract

The invention relates to a locking force adjustable separated full-contact bearing support special for a constant-velocity universal joint assembly, and belongs to the technical field of automobile constant-velocity universal joint assemblies. The problems that in an existing separated bearing support, a bearing is stressed unevenly in the radial direction, the outer ring of the bearing is prone to being broken, or a bearing rolling way is prone to being worn abnormally, consequently, early failures are caused, and finally the service life of the constant-velocity universal joint assembly cannot meet the automobile use requirements are mainly solved. The locking force adjustable separated full-contact bearing support is mainly characterized in that a bearing support, an upper gland, silicone rubber gaskets and fastening flange screws are included; the silicone rubber gaskets are arranged between cooperation faces of the upper gland and the bearing support; and when the screws are fastened, the pressing degree of the bearing can be controlled and judged according to the press deformation range of 30%-70% of the silicone rubber gaskets, visual control over the pressing force of the bearing is achieved, rationality and reliability of the bearing support are improved, and then the service life of a constant-velocity universal joint and the service life of the constant-velocity universal joint assembly are greatly prolonged. The locking force adjustable separated full-contact bearing support is mainly used for auxiliary supporting of the constant-velocity universal joint assembly.

Description

technical field [0001] The invention belongs to the technical field of automobile constant velocity universal joint assembly. In particular, it relates to a separate full-contact bearing support with adjustable locking force for an automobile constant velocity universal joint assembly. Background technique [0002] The constant velocity universal joint assembly is a key component in the car transmission system. There are many types of practical application structures in the market. Generally, two different types of universal joints are combined into a constant velocity universal joint assembly connected to the gearbox through an intermediate shaft. Between the hub and the hub to achieve the main purpose of smoothly and reliably transmitting the torque of the engine to the wheels. As the sales of mid-to-high-end cars and luxury cars continue to rise in the market, the pursuit of large displacement and large space for sedan models has become the mainstream development directi...

AI Technical Summary

Problems solved by technology

Through comprehensive analysis, the above 6 bearing support structures all have quality problems such as uneven bearing radial force to varying degrees, resulting in abnormal force rupture of the outer ring of the bearing or reduction of fit clearance, resulting in abnormal wear of the bearing raceway and early failure quality problems. In addition, the full-contact bearing support and the constant velocity universal joint assembly are press-fitted together, and there are problems such as installation by the main engine factory and maintenance and disassembly in the market. The combined bearing support is complex in composition, difficult to process parts, and high in manufacturing costs.

The separated structure is the most reasonable design among all structures, and there is also the problem of uneven radial force on the bearing

In short, the early rupture or wear failure of the bearing eventually leads to the fact that the service life of the constant velocity joint assembly cannot meet the requirements of the vehicle
