Below with reference to drawings and Examples, the technical solution of the utility model is described in further detail.
Fig. 1 is the sectional structure schematic diagram of traditional clutch release bearing.
Fig. 2 is the plan view of traditional clutch release bearing seal ring.
Fig. 3 is an embodiment's of the seal ring for clutch release bearing of the present utility model plan view.
Fig. 4 will be installed in the embodiment of seal ring shown in Fig. 3 after clutch release bearing corresponding to the local enlarged diagram of position shown in dotted line frame A in Fig. 1.
Fig. 5 is an embodiment's of clutch release bearing of the present utility model structural representation.
Embodiment
It should be noted that, below will illustrate by way of example principle, characteristics and the advantage of the seal ring for clutch release bearing of the present utility model, clutch release bearing and automobile, yet all descriptions only are used for describing, and they should be interpreted as the utility model is formed to any restriction.In addition, at this paper, in mentioned each embodiment, described or implicit any single technical characteristics, perhaps be shown or lie in any single technical characteristics in each accompanying drawing, still can between these technical characteristicss (or its equivalent), proceed combination in any or delete, thereby obtain of the present utility model more other embodiments that may directly not mention in this article.
Illustrate in a schematic way an embodiment's of the seal ring for clutch release bearing of the present utility model basic structure in Fig. 3.As shown in Figure 3, in this embodiment who provides, seal ring 10 comprises body 10a and lip 10b.Wherein, body 10a has first end 101 and the second end 102, and lip 10b is arranged between first end 101 and the second end 102 and is outwards outstanding.
Again please in conjunction with reference to figure 4, this figure is installed to after clutch release bearing above-mentioned seal ring embodiment corresponding to the local enlarged diagram of position shown in dotted line frame A in Fig. 1.As shown in this Fig. 4, the first end 101 of body 10a is disposed between the safety cover 1 and bearing outer ring 9 of clutch release bearing, in order to realize thus sealing effect, by seal ring 10, seals up bearing outer ring 9.Simultaneously, the second end 102 of body 10a is arranged to be resisted against on bearing inner race 3 and is used for being sealed, and also by seal ring 10, the bearing inner race of clutch release bearing 3 is sealed up.In order further to guarantee sealing effect, body 10a is arranged to be resisted against on the inwall 1a of safety cover 1 in the part between first end 101 and lip 10b.By adopting above arrangement, due to the bearing outer ring that has sealed up clutch release bearing and bearing inner race simultaneously, so not only can prevent the grease leakage, also can prevent entering of dust.In addition, because seal ring of the present utility model has above-mentioned optimizing structure design, therefore can be so that the space at sealing circle place become large, radiating effect is compared and is not affected with the conventional clutch seal ring.So, when using seal ring of the present utility model to guarantee heat dispersion, increased the sealability of clutch release bearing, improved its functional reliability and working life.
Under optional situation, as shown in Figure 4, can also on the lip 10b of seal ring 10, groove 103 be set, in order to strengthen the elastic deformability of seal ring 10, it is contacted with safety cover 1, bearing outer ring 9 and bearing inner race 3 etc. better and realize sealing.As an example, forming V-shape or U-shaped can be constructed in the cross section of above-mentioned groove.
The scope of sealing of comparing the conventional seals circle due to the seal ring for clutch release bearing of the present utility model is larger, efficiently solves that grease is revealed and dust such as enters at the aspect problem.Simultaneously; can be in the situation that change clutch release bearing safety cover shape; make the space between safety cover and release bearing become large; so just solved the heat dissipation problem of clutch release bearing; make and use after this seal ring when not sacrificing the clutch release bearing heat dispersion; improve its sealing, effectively prevent that the leakage of grease and dust etc. from entering.Therefore, be applicable to very much seal ring of the present utility model is installed and is applied on clutch release bearing.
Further show an embodiment's of clutch release bearing of the present utility model basic structure in Fig. 5, at this clutch release bearing, above-mentioned seal ring example is installed.As shown in Figure 5; for the purpose of simplifying drawing; wherein only illustrate and marked out the part constituent elementss such as safety cover 1, bearing inner race 3, steel ball 8; seal ring 10 is arranged on this clutch release bearing as previously mentioned, it by with safety cover 1, bearing inner race 3 and bearing outer ring be in contact with one another to realize the excellent sealing to clutch release bearing.
There is foregoing optimizing structure and good sealing effect and usability based on seal ring of the present utility model and clutch release bearing, therefore being applicable to very much such seal ring and clutch release bearing is attached on automobile, thereby can improve the sealing of existing clutch release bearing, improve its anti-dust performance, and effectively extend the working life of clutch release bearing.
More than enumerate some specific embodiments and illustrated in detail the seal ring for clutch release bearing of the present utility model, clutch release bearing and automobile, these a few examples are only for explanation principle of the present utility model and mode of execution thereof, but not to restriction of the present utility model, in the situation that do not break away from spirit and scope of the present utility model, those of ordinary skill in the art can also make various distortion and improvement.Therefore, all technological schemes that are equal to all should belong to category of the present utility model and be limited by every claim of the present utility model.
