Abstract
The utility model discloses a differential spider. The differential spider comprises a middle connector and a planetary gear shaft which is arranged on the middle connector crossly. The differential spider is characterized in that the planetary gear shaft and the middle connector are integral cold forging pieces, and the middle connector has a central circular hole. The differential spider disclosed by the utility model has the advantages of simple structure and convenience for machining and assembling.
Description
Technical field
The utility model relates to a kind of component of automobile differential, is specifically related to a kind of differential spider.
Background technique
Automobile differential is the main part of automobile drive axle, and in the time of automobile turning, the radius of turn of two wheels is different; Need a wheel to change to hurry up one a little slower; Realize the two-wheeled different rotating speeds, must realize that a cross axle is arranged in the differential mechanism by differential mechanism; Four planetary pinions are housed, and differential spider needs high dimension precision and positional accuracy.For guaranteeing the positional accuracy of differential spider; Differential spider adopts the branch body structure usually; Article two, the planet pin that is crossed as cross is each other processed respectively, is assembled together then, and wherein a planet pin also will be fixed on differential casing through pin; So the differential spider of existing technology not only structure is complicated, and processing and assembling are all quite loaded down with trivial details.
Summary of the invention
In view of the problem of known technology existence at present, it is a kind of simple in structure that the purpose of the utility model is intended to provide, processing and differential spider easy to assembly.
The utility model takes following technological scheme to accomplish:
Differential spider comprises middle connected body and on middle connected body, is the planet pin that cross is arranged that it is characterized in that: planet pin and middle connected body are integral cold forging spare.Middle connected body is provided with center hole.
The differential spider that the utility model provides has adopted integral cold forging spare structure, not only make simple in structure, and be convenient to processing and the assembling; For guaranteeing the machining accuracy of cross axle; The middle connected body of cross axle is provided with center hole; Utilize the accurate location of center hole; Cross axle can be easier to realize the processing request of high dimensional accuracy and positional accuracy, has effectively guaranteed the proper functioning of automobile differential, improves the working life of automobile differential.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is the structural drawing of the utility model.
Embodiment
Accompanying drawing has been represented the technological scheme and the embodiment of the utility model, combines accompanying drawing to further describe each relevant details and working principle thereof of embodiment below again.
As shown in the figure; The differential spider of the utility model comprises middle connected body 2 and on middle connected body 2, is the planet pin 1 that cross is arranged that planet pin 1 is an integral cold forging spare with middle connected body 2; Middle connected body 2 has cylindrical profile; Middle connected body 2 is provided with center hole 3, utilizes the accurate location of center hole 3, and cross axle can be easier to realize the processing request of high dimensional accuracy and positional accuracy.
Claims (2)
1. differential spider comprises middle connected body and on middle connected body, is the planet pin that cross is arranged, it is characterized in that: planet pin and middle connected body are integral cold forging spare.
2. differential spider as claimed in claim 1 is characterized in that: middle connected body is provided with center hole.
