Abstract
Disclosed is a connecting structure of a three-pin support and a shaft. The connecting structure comprises the three-pin support and the shaft. An end portion of the shaft is provided with an outer spline, an inner spline is arranged inside the three-pin support, the three-pin support is connected with the shaft in a sleeved mode through the splines, the end portion of the shaft is provided with a clamp spring groove, a clamp spring is installed inside the clamp spring groove, an annular boss is arranged on the shaft, an end face of the boss is movably connected with one end face of the three-pin support, and the other end face of the three-pin support is movably connected with an end face of the clamp spring. The connecting structure has the advantages that a baffle ring is saved, the machining process of a baffle ring groove is reduced, product cost is lowered, the connecting structure of the three-pin support and the shaft is simpler and more reliable in work; during assembling, the three-pin support is arranged on the shaft in a sleeved mode, after the end face of the three-pin support abuts against the end face of the boss, the clamp spring is then installed, therefore, the assembling process is simplified, labor intensity is lowered and assembling efficiency is also improved.
Description
Technical field
The utility model provides the linkage structure of spider and axle in a kind of automobile constant velocity cardan joint transmission shaft, belongs to the auto parts and components field.
Background technique
At present, the market competition of minicar transmission shaft is extremely fierce, so requires to reduce the processing cost of part, and reduces the processing beat of operation, shortening workpiece, the part that the minimizing assembling needs use, is the main path that reduces costs.in the constant velocity cardan joint transmission shaft assembling, spider and being connected of axle are the important critical processes in assembling, the linkage structure of spider and axle was to be processed with circlip groove and jump-ring slot on the external splines of axle head in the past, circlip groove is equipped with back-up ring, jump ring is housed in jump-ring slot, the internal spline of spider coordinates socket with the external splines of axle, the spider both ends of the surface are flexibly connected with back-up ring and jump ring respectively, back-up ring and jump ring are fixed on spider the specified position of axle, shortcoming is first back-up ring to be installed, be set with again spider, jump ring is installed finally, its assembling is loaded down with trivial details, the efficiency of assembling is low, labor intensity is large, the cost of processing circlip groove is high on external splines simultaneously.
Summary of the invention
The purpose of this utility model is to provide the linkage structure of a kind of spider and axle, uses this structure can simplify assembly process, reduces labor intensity, improves efficiency of assembling, saves cost.
The technical solution of the utility model is: the linkage structure of a kind of spider and axle, comprise spider and axle, the end of axle is provided with external splines, be provided with internal spline in spider, spider and axle are socketed by spline, and the end of axle is provided with jump-ring slot, jump ring is housed in jump-ring slot, it is characterized in that: axle is provided with the boss of annular, and an end face of the end face of boss and spider is flexibly connected, and another end face of spider and the end face of jump ring are flexibly connected.
The utility model has the advantages that: boss replaces the back-up ring of installing on original axle, save a back-up ring and the manufacturing procedure that has reduced by a circlip groove, reduced the cost of product, make the linkage structure of spider and axle simpler, work more reliable, during assembling, as long as after the end face that spider is sleeved on axle the end face that makes spider and boss is close to, jump ring is installed is again got final product, simplified assembly process, reduced labor intensity, also improved efficiency of assembling.

Fig. 2 is the linkage structure schematic diagram of a kind of spider of the utility model and axle;
Fig. 3 is the linkage structure schematic diagram of conventional art spider and axle.
1 spider, 2 axles, 3 boss, 4 jump rings, 5 jump-ring slots, 6 circlip grooves, 7 back-up rings in figure.
Embodiment
The linkage structure of a kind of spider and axle, comprise spider 1 and axle 2, the end of axle is provided with external splines, is provided with internal spline in spider, and spider and axle are socketed by spline, the end of axle is provided with jump-ring slot 5, jump ring 4 is housed in jump-ring slot, and axle is provided with the boss 3 of annular, and an end face of the end face of boss and spider is flexibly connected, another end face of spider and the end face of jump ring are flexibly connected, and spider will be fixed on the specified position of axle by boss and jump ring.
Being provided with the back-up ring 7 of installing on the original axle of boss replacement on axle, save a back-up ring and the manufacturing procedure that has reduced by a circlip groove 6, reduced the cost of product, make the linkage structure of spider and axle simpler, work more reliable.
During assembling, as long as after the end face that spider is sleeved on axle the end face that makes spider and boss is close to, then jump ring is installed is got final product, simplified assembly process, reduced labor intensity, also improved efficiency of assembling.
