Abstract
The utility model discloses a constant velocity universal joint, which comprises a counter shaft. A three-pin assembly is mounted onto the right end of the counter shaft, the three-pin assembly slides inside the bell shaped housing, and an elastic sliding structure is provided between the end portion of the three-pin assembly and the bottom of the bell shaped housing. The elastic sliding structure comprises a spring, the left end of the spring is arranged inside the spring cap, the spring cap is arranged on the terminal portion of the three-pin assembly, and the right end of the spring is provided on the bottom of the bell shaped housing. Because of providing an elastic sliding structure between the end portion of the three-pin assembly and the bottom of the bell shaped housing, the utility model can not only prevent excessive sliding of the three-pin assembly, but also reduce the impact generated from the sliding of the three-pin assembly.
Description
Technical field
The utility model relates to a kind of constant velocity universal joint.
Background technique
The rzeppa universal joint drive shaft assembly is a kind ofly can provide pivot angle, retractable constant velocity driving shaft again, and the jack shaft right-hand member is three pin assemblies, and three pin assemblies slide in outer race.Slippage is excessive, can damage universal joint.China's utility model patent 200520014136.4 discloses a kind of rzeppa universal joint live axle on October 4th, 2006, for being provided with fixed mechanism, the sliding sleeve mouth prevents that three ball pins from skidding off internal spherical cage sliding sleeve runway and designing, fix a baffle plate at internal spherical cage sliding sleeve mouth, open a breach with the ball place of corresponding three ball pins on the baffle plate, the diameter of this breach is less than the diameter of the ball on the three ball pins, be fixed when making three ball pins slide onto the sliding sleeve oral area, can't continue slippage.Though this structure can prevent the undue slippage of three ball pins, the impact that produces during its slippage is bigger, and the proper functioning of universal joint is exerted an influence.
The model utility content
Technical problem to be solved in the utility model just provides a kind of constant velocity universal joint, can prevent the undue slippage of three pin assemblies, can reduce the impact force that three pin slippages produce again.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: a kind of constant velocity universal joint, comprise jack shaft, described jack shaft right-hand member is equipped with three pin assemblies, described three pin assemblies slide in outer race, it is characterized in that: be provided with the elasticity sliding motion structure between described three pin assembly ends and outer race diapire.
As preferably, described elasticity sliding motion structure comprises spring, and described spring left end is located in the spring compressor, and spring compressor is located at three pin assembly ends, and described spring right-hand member is located in the groove of outer race diapire.Spring has good stretchability, and can absorb the impact force that produces in the slipping.
As preferably, described spring compressor bottom is the circular arc concave inward structure, and described three pin assembly ends are provided with the circular arc projection, and described circular arc concave inward structure relies on the circular arc projection.Spring compressor is relatively more firm in the course of the work, and simple in structure, easy for installation.
As preferably, described outer race is provided with back-up ring between three pin assembly leftward position and jack shaft.Further improve the performance of its antiskid by back-up ring.
The utility model can prevent the undue slippage of three pin assemblies owing to be provided with the elasticity sliding motion structure between three pin assembly ends and outer race diapire, can reduce the impact force that three pin slippages produce again.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is spring, spring compressor and three pin assembly linkage structure schematic representation.
