Slot plays the effective length that auxiliary extends installation threaded hole, improves replaceability, the use scope of excessive product.
Preferably, the locating shaft end face diameter is slightly larger than the internal diameter of reset spring, the end face of the locating shaft
Spherical shape.
Automatic homing is remain stationary when locating shaft allows constant velocity cardan joint external ball cage not work together with reset spring, limits vapour
When vehicle does not work constant velocity cardan joint external ball cage because there are pivot angle still carry out playbacking in the case where work it is static.It is straight to position axial end
Diameter is slightly larger than the internal diameter of reset spring, and preventing the pivot angle of mandrel from rotating influences locating shaft and reset spring disengaging.The end of locating shaft
The spherical shape in face can facilitate to be halved together inside locating shaft and reset spring.
Preferably, the dust cover front end outer wall is equipped with the clip two for the socket that is fastened with bell body, it is described
Dust cover rear end outer wall is equipped with the clip one for the socket that is fastened with mandrel.
Clip one plays the fastening effect of dust cover and core shaft end, clip two plays dust cover and bell body is fastened set
It connects, also acting as prevents the lubricating grease in grease pocket from leaking outside.
The utility model can reach following effect:
The utility model provides a kind of constant velocity cardan joint external ball cage of automatic homing, compared with prior art, tool
Have compact-sized, eliminates pivot angle situation existing for constant velocity cardan joint external ball cage when automobile does not work, extend service life, subtract
Maintenance cost is lacked.
