Abstract
The utility model discloses an axle shaft sleeve of an automotive rear axle. The axle shaft sleeve of the automotive rear axle comprises a sleeve seat and a sleeve shaft connected with the sleeve seat, wherein a flange disc is arranged at the circumference of the sleeve seat, two through holes are respectively formed in the middle of the sleeve seat and in the middle of the sleeve shaft, the connecting position between the sleeve seat and the sleeve shaft is of a three-layer stair-stepping structure, and the connecting position of every two layers of stair steps is an inclined plane. By means of the structure, the connection between the axle shaft sleeve and other parts is firmer, and the phenomenon that the axle shaft sleeve frequently falls off in the mechanical transmission process is reduced.
Description
Technical field
The utility model discloses a kind of mechanical component, be specifically related to a kind of axle tube for automobile axle.
Background technology
Axle tube on the automobile axle housing used and often can cause long afterwards making sleeve pipe loosening and move; will cause so the firm spindle nose thread abrasion of wheel; bearing is moved axially; wheel is in operation and waves; increased resistance to motion, affected brake efficiency, made the pernicious abrasion of tire; under excessive responsive to axial force, can produce " flywheel " accident when serious.So axle tube installed and fixed proposed higher requirement.
The utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of axle tube for automobile axle.
Technical scheme: for solving the problems of the technologies described above, the car rear axle semi-axis sleeve pipe that the utility model provides, comprise casing seat and the quill drive that links to each other with casing seat, described casing seat circumference place is provided with a flange, be equipped with a through hole in the middle of described casing seat and the quill drive, the junction of described casing seat and quill drive is three layers of step structure, and the junction all is the inclined-plane between stepped.
Further, the through hole in the described quill drive is cylindrical.
Further, the through hole in the described casing seat is tapered.
Beneficial effect: the utility model in terms of existing technologies, and is more firm with being connected between the miscellaneous part, reduced the phenomenon that causes the slip that miscellaneous part often occurs because axle tube is insecure in mechanical transmission course.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of car rear axle semi-axis sleeve pipe, comprise casing seat 2 and the quill drive 1 that links to each other with casing seat 2, described casing seat 2 circumference places are provided with a flange 3, be equipped with a through hole in the middle of described casing seat 2 and the quill drive 1, described casing seat 2 is three layers of step structure with the junction 4 of quill drive 1, and the junction all is the inclined-plane between stepped; Through hole in the described quill drive 1 is cylindrical, and the through hole in the described casing seat 2 is tapered.
The utility model can with miscellaneous part between be connected more firmly, reduced the phenomenon that causes the slip that miscellaneous part often occurs because axle tube is insecure in mechanical transmission course.
The above only is preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
