Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1 and 2, the fixing structure of the anti-friction washer 200 of the driving shaft 400 according to the embodiment of the present utility model includes a clamping collar 100, the anti-friction washer 200, and a driving shaft fixing section 300, wherein the driving shaft fixing section 300 is used to connect with the driving shaft 400, which may be fixed to one end of the driving shaft 400. The antifriction spacer 200 and the clamping retainer 100 are respectively sleeved on the driving shaft 400, that is, the antifriction spacer 200 and the clamping retainer 100 are both in an annular structure, and the driving shaft fixing joint 300, the antifriction spacer 200 and the clamping retainer 100 are sequentially arranged along the axial direction of the driving shaft 400.
Referring to fig. 4, the clamping ring 100 includes a ring body 110 and a connection portion 120, the connection portion 120 is disposed at a side of the ring body 110 facing the antifriction pad 200, and in particular, the connection portion 120 may be connected to an end portion of an outer ring of the ring body 110. The connection portion 120 is provided with a protrusion 130 on a side facing the driving shaft 400, and correspondingly, the driving shaft fixing section 300 is provided with a groove 310, when the driving shaft fixing section 300, the antifriction pad 200 and the clamping retainer 100 are assembled, the protrusion 130 is clamped in the groove 310, and at this time, two opposite side surfaces of the antifriction pad 200 are respectively clung to the driving shaft fixing section 300 and the clamping retainer 100, so that the antifriction pad 200 can be relatively fixed, that is, the antifriction pad 200 and the driving shaft 400 are relatively fixed.
In this embodiment, it should be understood that the inner ring diameter of the retainer ring body 110 is larger than the inner ring diameter of the anti-friction washer 200, and the inner ring diameter of the retainer ring body 110 is smaller than the outer ring diameter of the anti-friction washer 200, so that the front projection of the retainer ring body 110 overlaps the front projection of the anti-friction washer 200 in the plane perpendicular to the axial direction of the drive shaft 400, and the outer ring diameter of the retainer ring body 110 is larger than the outer ring diameter of the anti-friction washer 200, so that the connection portion 120 is not interfered by the anti-friction washer 200 when assembled with the drive shaft fixing joint 300, thereby ensuring that the anti-friction washer 200 can be clamped by the clamping retainer ring 100 and the drive shaft fixing joint 300. Since the manner of glue adhesion is avoided when the antifriction pad 200 is installed in this embodiment, but a mechanically limited assembly manner is adopted, stable connection between the antifriction pad 200 and the drive shaft fixing section 300 can be ensured.
In some embodiments, the connection part 120 may be plural, the plural connection parts 120 are uniformly distributed along the circumferential direction of the retainer ring body 110, and a side of each connection part 120 facing the driving shaft 400 is provided with a protrusion 130. By providing the plurality of protruding portions 130, the stability of the connection between the clip ring 100 and the drive shaft fixing section 300 can be enhanced, and the stability of the connection between the antifriction spacer 200 and the drive shaft fixing section 300 can be further improved.
On this basis, the plurality of grooves 310 provided on the driving shaft fixing section 300 may be plural, and the plurality of grooves 310 are provided in one-to-one correspondence with the plurality of protrusions 130. When the driving shaft fixing joint 300, the antifriction pad 200 and the clamping ring 100 are assembled, each protruding portion 130 is clamped in the corresponding groove 310, so that the clamping ring 100 is effectively positioned.
Alternatively, the groove 310 may be formed integrally, that is, the groove 310 is formed on the driving shaft fixing section 300 around the circumference of the driving shaft 400, so that the connection between the protrusion 130 and the groove 310 can be facilitated, and time and effort can be saved when the driving shaft fixing section 300, the antifriction pad 200 and the clip ring 100 are assembled.
In some embodiments, the connection 120 may be disposed about the circumference of the retaining ring body 110, in which case the boss 130 may also be disposed about the circumference of the retaining ring body 110. Correspondingly, the groove 310 is disposed on the fixed driving shaft joint 300 around the circumference of the driving shaft 400, and when the fixed driving shaft joint 300, the antifriction pad 200 and the clamping retainer ring 100 are assembled, the protrusion 130 is clamped with the groove 310, so as to better ensure a good fixing effect between the antifriction pad 200 and the fixed driving shaft joint 300.
Further, a limit rib may be further disposed between the protrusion 130 and the groove 310 to prevent the protrusion 130 from rotating around the driving shaft 400 relative to the groove 310, so as to avoid the influence of the fixing effect between the antifriction pad 200 and the driving shaft fixing section 300 during the rotation process.
In addition, as shown in fig. 4, a side surface of the connection portion 120 facing the drive shaft 400 may be in close contact with a surface of the drive shaft fixing section 300, that is, the clip retainer ring 100 is in close contact with not only the antifriction pad 200 in the axial direction of the drive shaft 400 but also the drive shaft fixing section 300 in the circumferential direction of the drive shaft 400. The fixing effect between the antifriction pad 200 and the drive shaft fixing section 300 can be further improved by the multiple limit.
In some embodiments, the retainer ring body 110 and the connecting portion 120 may be a unitary structure, and the material of the retainer ring 100 may be plastic. The production cost can be saved while the fixing effect is ensured.
As shown in fig. 3 and 4, when the fixing structure of the antifriction spacer 200 of the driving shaft 400 in this embodiment is assembled with the hub bearing 500, the end face of the hub bearing 500 passes through the inner ring of the clamping retainer ring 100 and abuts against the antifriction spacer 200, and at this time, since the antifriction spacer 200 is relatively fixed with the driving shaft fixing joint 300, the antifriction spacer 200 can play a good role in eliminating abnormal friction noise generated between the end face of the driving shaft 400 and the end face of the hub bearing 500, thereby ensuring the performance of the vehicle.
The antifriction pad 200 in this embodiment may be a antifriction pad made of a nonmetallic material, or in other embodiments, the antifriction pad 200 may be made of a metallic material, which is not limited in this embodiment.
Based on the same conception, the present utility model may also provide a vehicle including the drive shaft antifriction pad fixing structure described in any one of the above embodiments.
It will be apparent to those skilled in the art that various modifications and variations can be made to the embodiments of the present utility model without departing from the spirit and scope of the utility model. Thus, it is intended that the present utility model also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
