Description

[Brief explanation of the drawing]

Figures 1 to 3 show an embodiment of the clutch release bearing unit of the present invention, with Figure 1 being a front view, Figure 2 being a half vertical side view, and Figure 3 incorporating the clutch release bearing unit into the bearing unit. Front view of the locking spring,
Fig. 4 is a perspective view of an anvil showing another embodiment of the present invention, Figs. 5 and 6 show an example of a clutch mechanism for a manual transmission, and Fig. 5 shows the state during power transmission. Fig. 6 is a schematic side view showing the state in which the power is being cut off, Fig. 7 is a front view showing an example of a conventional clutch release bearing unit, Fig. 8 is a side view, and Fig. 9 is a half cross section. It is a diagram. 1: Clutch pedal, 2: Cable, 3: Release fork, 4: Pivot, 5: Shaft, 6: Bearing unit for clutch release, 7: Diaphragm spring, 8: Clutch plate, 9: Flywheel, 10:

Claims (1)

[Claims for Utility Model Registration] (1) A sleeve fitted onto the outer circumferential surface of the shaft so as to be able to slide freely in the axial direction, an outward flange fixed to the outer circumferential surface of the sleeve, and this outward flange. By engaging the release bearing held on one side of the release fork and the inner surface of the release fork with a pair of mutually parallel flat surfaces fixed at positions that sandwich the sleeve on the other side of the outward flange. In a clutch release bearing unit comprising a rotation prevention member that prevents relative rotation between the sleeve and the release fork, the center of the pair of flat surfaces is set so that the center of the release fork is inserted into the clutch release fork. A bearing unit for a clutch release characterized by being shifted in the opposite direction. (2) A sleeve fitted onto the outer circumferential surface of the shaft so as to be able to slide freely in the axial direction, an outward flange fixed to the outer circumferential surface of the sleeve, and a release held on one side of the outward flange. The relative relationship between the sleeve and the release fork is improved by the engagement of the bearing and the inner surface of the release fork with a pair of mutually parallel flat surfaces fixed on the other side of the outward flange portion at positions that sandwich the sleeve. A rotation prevention member that prevents rotation, a pair of protruding plate portions corresponding to the pair of flat surfaces and protruding outward from the outward flange portion, and the entire body is made of an elastic material. Elastic coupling parts are provided at both ends of the arc-shaped base surrounding the bearing to elastically couple the protruding plate part and the tip of the release fork via a continuous part that engages with the protruding plate part. In a bearing unit for a clutch release consisting of a locking spring, the center of the pair of flat surfaces is shifted from the center of the sleeve to the side opposite to the insertion direction of the release fork, and By slanting the edges of the protruding plate parts, the distance between the edges of both protruding plate parts is gradually widened from one side to the other, and the distance between the continuous parts in the free state of the locking spring is increased. A bearing unit for a clutch release, characterized in that the spacing between the projecting plate parts is wider than the spacing on the narrow side and narrower than the spacing on the wide side.
