Wire retaining ring at the mouth of the sliding universal joint

Abstract

The invention discloses a steel wire retaining ring at the mouth of a sliding universal joint. The embedded part in the joint housing, the outer ring part is on the first plane, the embedded part is on the second plane, the first plane and the second plane are parallel, the outer ring part, the connecting part and the embedded part Sequentially spaced and connected end to end, one of the embedded parts is provided with an opening. The sliding universal joint mouth wire retaining ring obtained by the present invention can shorten the length of the universal joint shell and reduce the material under the same sliding requirements. Cost; under the same shell length, the sliding distance of the ball ring is lengthened; the steel wire retaining ring at the mouth of the sliding universal joint is easy to manufacture, fast in manufacturing, low in manufacturing cost and high in reliability; easy to install, no additional It can be fixed on the universal housing by its own elastic deformation; the structure is simple and the weight is light.

Description

technical field [0001] The invention relates to the field of ball cage retaining rings, in particular to a steel wire retaining ring at the mouth of a sliding universal joint. Background technique [0002] The universal joint at the sliding end of the ball cage type constant velocity drive shaft is usually designed as a three-pronged raceway type. When the three-pronged joint slides normally in the raceway, the three-pronged joint will often be pulled out when sliding in the raceway before the OEM loads the vehicle. Because the ball ring can freely rotate and slide up and down on the shaft head, it will increase the difficulty of automatic rebound or manual rebound into the raceway, and cause damage or adverse effects to other parts. A retaining ring is designed. [0003] Generally, the anti-detachment measures on the market use the shell mouth riveting point scheme, but this kind of scheme requires special equipment and special tooling to press riveting the shell mouth to ...

Problems solved by technology

[0002] The universal joint at the sliding end of the cage type constant velocity drive shaft is usually designed as a three-prong raceway type. When the three-prong slides normally in the raceway, the three-prong will often pull out when sliding in the raceway before the OEM installs the car. Because the ball ring can freely rotate and slide up and down on the shaft head, it will increase the difficulty of automatic rebound or manual rebound into the raceway, and cause damage or adverse effects to other parts. Therefore, in order to prevent the trident ball ring from falling out, the designer, retaining ring

[0003] Generally, the anti-loosening measures on the market adopt the scheme of riveting points at the mouth of the shell, but this kind of scheme needs to use special equipment and special tooling to press the appropriate pits at the mouth of the shell, so that the mouth of the shell is squeezed and deformed, and then the The trident assembly is press-fitted into the raceway with high pressure. This solution has defects such as: high equipment cost, high process control cost, part forming is destructive, and it is not conducive to after-sales disassembly and assembly.

[0004] There is also a profiling dust cover solution for anti-loosening measures, which transfers the reaction force that prevents the ball ring from coming out to the clamp of the dust cover, resulting in another failure risk. This solution has: high cost of mold opening, verification Defects such as long cycle and unsatisfactory effect to achieve the purpose

[0005] And there are also circular steel wire retaining rings at the mouth and imitation steel wire retaining rings at the mouth. This scheme has the advantages of shortening the sliding stroke of the ball ring in the raceway, and under the same sliding requirements, the inner cavity of the shell needs to be lengthened , high material cost and unsatisfactory effect to achieve the purpose, etc.
