Description
Technical Field
The utility model relates to an auxiliary fixtures technical field especially relates to a wheel hub brake disc installation sliding sleeve.
Background
The automobile front axle hub brake disc is connected with the steering knuckle through two coaxial bearings, when the automobile front axle hub brake disc and the steering knuckle are installed specifically, the two bearings are installed in the hub brake disc, then the hub brake disc is sleeved on the wheel shaft of the steering knuckle, although the bearings and the wheel shaft are in clearance fit, workers are still difficult to assemble actually, in addition, the brake disc is heavy, and generally, 30-50 seconds are needed for assembling one brake disc, so that the production efficiency and the assembling process of the whole production line are greatly influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to prior art not enough, and provide a wheel hub brake disc installation sliding sleeve, its direction sliding sleeve of installation on the knuckle plays the effect of supporting and direction to the bearing behind the brake disc to reduce the installation degree of difficulty, improve the installation effectiveness.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a hub brake disc installation sliding sleeve, includes the guide cylinder, the guide cylinder is one end open-ended pipe, the guide cylinder is including the outer periphery that plays the guide effect and the inner circumferential surface that cup joints with the knuckle shaft, inner circumferential surface is provided with the internal thread, the one end of the closed end mouth of guide cylinder is connected with the cone of the brake disc suit of being convenient for, the less one end of diameter of cone is connected with the pneumatic wrench of being convenient for and twists the internal thread joint station.
Further, the diameter of the outer circumferential surface is equal to the diameter of the knuckle bearing mounting surface.
Further, the tolerance of the outer circumferential surface falls within the tolerance of the knuckle bearing mounting surface.
Further, the internal thread is located at the inner position of the inner circumferential surface, and the diameter of the inner circumferential surface between the internal thread and the pipe opening is larger than the outer diameter of the internal thread.
Furthermore, the clamping station is an outer hexagon nut welded with the cone.
The utility model has the advantages that: the utility model provides a hub brake disc installation sliding sleeve, its includes the guide cylinder, the guide cylinder is one end open-ended pipe, the guide cylinder is including the outer periphery that plays the guide effect and the inner circumferential face that cup joints with the knuckle shaft, inner circumferential face is provided with the internal thread, the one end of the closed end mouth of guide cylinder is connected with the cone of the brake disc suit of being convenient for, the less one end of diameter of cone is connected with the pneumatic wrench of being convenient for and twists the internal thread joint station. The utility model discloses simple structure, low cost plays supporting and guide effect when assembly wheel hub brake disc, can the greatly reduced installation degree of difficulty to improve the installation effectiveness.

Detailed Description
The following detailed description of the present invention is provided in connection with the accompanying drawings and the embodiments, and is not intended to limit the scope of the invention.
As shown in fig. 1-3, the hub brake disc mounting sliding sleeve of the present embodiment includes a guiding cylinder 1, where the guiding cylinder 1 is a circular tube with an open end, the guiding cylinder 1 includes an outer circumferential surface 11 for guiding and an inner circumferential surface 12 sleeved with a knuckle axle, the inner circumferential surface 12 is provided with an internal thread 13, one end of a closed end of the guiding cylinder 1 is connected with a cone 2 for facilitating the brake disc to be sleeved, and one end of the cone 2 with a smaller diameter is connected with a clamping station 3 for facilitating a pneumatic wrench to screw the internal thread 13.
When the wheel hub brake device is used, the clamping station 3 is firstly screwed by a pneumatic wrench, the sliding sleeve is installed on a steering knuckle through the internal thread 13, then the wheel hub brake disc which is preassembled is pushed to the steering knuckle along the sliding sleeve, and after the wheel hub brake disc is installed, the sliding sleeve is taken down by a pneumatic wrench. The sliding sleeve has a supporting function on the hub brake disc, so that labor is saved, meanwhile, the front bearing is convenient to center and easy to install, meanwhile, the rear bearing is convenient to install, the installation difficulty is reduced, and the installation efficiency is improved; after the sliding sleeve is adopted for installation, the average installation time of each hub brake disc is 10-15 seconds, including the time for installing and disassembling the sliding sleeve.
To achieve the guiding effect of the sliding sleeve, the diameter of the outer circumferential surface 11 is equal to the diameter of the knuckle bearing mounting surface, and the tolerance of the outer circumferential surface 11 falls within the tolerance of the knuckle bearing mounting surface. Of course, the outer circumferential surface 11 is not less smooth than the knuckle bearing mounting surface.
In order to reduce the time for installing and disassembling the sliding sleeve, the internal thread 13 may not be fully distributed on the inner circumferential surface 12, i.e. the internal thread 13 is located at the inner position of the inner circumferential surface 12, and the diameter of the inner circumferential surface 12 between the internal thread 13 and the pipe orifice is larger than the outer diameter of the internal thread 13.
The clamping station 3 is an outer hexagon nut welded with the cone 2, and can also be welded with other standard fasteners or directly processed at the small end of the cone 2 to be matched with the pneumatic wrench in the clamping station 3.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
