Abstract
An inner constant velocity universal joint with a dismountable input shaft relates to the field of automobile driving force transmission and comprises the input shaft and a spherical housing. A groove for storing a joint spider is reserved in the spherical housing. A slot is reserved at the bottom of the groove. Equidistant protrusions are arranged on the inner wall of the slot in the axial direction of the input shaft. The input shaft matching with the spherical shell is embedded in the slot. Recesses matching with the protrusions are reserved in the axial direction of the input shaft. The inner constant velocity universal joint with the dismountable input shaft enables a constant velocity universal joint to be applicable to different input shafts.
Description
Technical field
The present invention relates to Automobile drive power and transmit field, particularly input shaft reassembling type internal spherical cage.
Background technique
Between the input shaft of prior art and the ball cage for being fixedly connected with, the replacing of the inconvenient input shaft of this connection, each input shaft need to be equipped with a ball cage, so that cost of production increases.
In publication number is the open file of CN 202203294U, disclose a kind of Quick-change type ball-cage universal coupling, be used for the fast assembling-disassembling of coupling.The drive end flange is connected with drive end ball cage, and middle axle sleeve is that splined shaft cooperates with splined shaft, and splined shaft links to each other with driven end ball cage, between driven end ball cage and the driven end flange fast shifter setting sleeve is housed, has positioning hole on it, in-built steel ball, gland is housed on it, spring is housed in the gland.During dismounting, promote gland, setting sleeve moves axially, and steel ball enters gland, removes drive end parts and driven end component axial location, continues to promote gland, positioning end parts and driven end flange axial separation; During installation, the driven end flange is pushed setting sleeve, unclamp gland, spring promotes gland, and steel ball is pressed in the setting sleeve, and restriction drive end and driven end component axial move, and finish installation; Be fixedly connected with between input shaft in the open file and the ball cage, input shaft can't be changed.
Summary of the invention
The objective of the invention is for the internal spherical cage that input shaft can dismounting is provided, so that same ball cage goes for different input shafts.
Above-mentioned technical purpose of the present invention is achieved by the following technical programs: input shaft reassembling type internal spherical cage, comprise input shaft and outer race, offer in the described outer race be used to the groove of depositing the joint spider, offer hole slot on the described bottom portion of groove, described hole slot inwall upwards is provided with mutually equidistant projection in the footpath of described input shaft, described input shaft cooperates with described outer race and is embedded in the described hole slot, and the footpath of described input shaft upwards offers the recess that cooperates described projection.
As preferably, described hole slot sidewall has one in the axial direction away from the extension part of described groove, and described extension part is provided with and makes described input shaft be fixed in fixing part in the described hole slot.
As preferably, the described hole slot place of described bottom portion of groove is coated with the sealing blanking cover.
As preferably, described input shaft is being provided with the hole back-up ring at the described groove near-end of distance.
As preferably, described input shaft is being provided with shaft block ring at the described groove far-end of distance.
The present invention has following beneficial effect: the input shaft that links to each other with outer race can be changed, saved and all will be provided with on the different input shafts with the needed material of a ball cage, arranging of blanking cover can prevent effectively, the connection of spline makes the joint can once be subjected to axial force, and so that the joint has the axial restraint effect, the increase of fixing part is so that fixing between input shaft and the outer race is more firm.
