Abstract

The utility model relates to a release bearing assembly of a simplified self-aligning clutch, which comprises a bearing component and a T-shaped bearing block. The bearing component consists of an inner bearing ring, an outer bearing ring, a retaining frame and a steel ball, the T-shaped end surface of the T-shaped bearing block is provided with an annular groove, the inner end surface of the outer bearing ring is connected with the bottom of the annular groove of the T-shaped bearing block, one side of a ring-shaped self-aligning spring is clamped on and connected with the T-shaped bearing block, the other side of the self-aligning spring is pressed on and connected with the outer end surface of the outer bearing ring, and a radial clearance A with a self-aligning axle is arranged betweenthe outer diameter of the outer bearing ring and the wall of the annular groove of the T-shaped bearing block. The utility model can realize the functions of the cover and the wavy spring in the traditional structure only through one self-aligning spring, thereby simplifying the structure, reducing the weight and lowering the manufacturing costs.

Description

Reduced form self-aligning separable bearing of clutch assembly

Technical field

The utility model relates to a kind of reduced form self-aligning separable bearing of clutch assembly, belongs to clutch release bearing technical field used on the Motor Vehicle.

Background technique

Clutch is between motor and gearbox, clutch is when transferring power and cut-out power, its operating mechanism is stirred sleeve by disengaging yoke, sleeve promotion declutch shaft is made to be moved axially, the push-press separation lever is around its spot wobble, thereby drive separation pull bar makes platen engage with driven disc or separates.But when the shaft axis of bearing unit and the shaft axis disalignment of clutch, can increase the frictional force of release bearing, and quicken the wearing and tearing of release bearing.Therefore present clutch release bearing all adopts the self-regulated heart function, one wavy spring is withstood on bearing inner race and the outer cover, and outer cover is connected on the sleeve, be provided with radial clearance between sleeve and the bearing inner race, under the elastic force effect of wavy spring, can carry out automatic compensation adjustment by this radial clearance, guarantee that release bearing and clutch shaft keep coaxial, solve the problem that causes clutch and release bearing premature wear because of release bearing and clutch disalignment.But the wavy spring of this structure needs to be connected on the sleeve installation and processing complexity by outer cover.

Summary of the invention

The purpose of this utility model provides a kind of simplified structure, lightweight reduced form self-aligning separable bearing of clutch assembly.

The utility model is that the technological scheme that achieves the above object is: a kind of reduced form self-aligning separable bearing of clutch assembly, comprise bearing inner race, bearing outer ring, retainer, the bearing unit that steel ball constitutes, it is characterized in that: also have T oblique crank Z bearing, the T shape end face of T oblique crank Z bearing has circular groove, the bottom land of the circular groove of the interior edge face of bearing outer ring and T oblique crank Z bearing joins, aligning spring one side of ring-type is connected on the T oblique crank Z bearing, the side pressure in addition of aligning spring is connected on the exterior edge face of bearing outer ring, and is provided with the radial clearance A that can regulate the axle center automatically between the cell wall of the external diameter of bearing outer ring and T oblique crank Z bearing circular groove.

The utility model is provided with circular groove at the T shape end face of T oblique crank Z bearing, and the bearing outer ring of bearing unit withstands on the bottom land of this circular groove, the aligning spring is installed on bearing outer ring and the T oblique crank Z bearing, owing to be provided with radial clearance A between the cell wall of T oblique crank Z bearing circular groove and the bearing outer ring, therefore the bearing unit frictional force that overcomes the aligning spring can be carried out self-aligning, bearing outer ring is linked to each other all the time with T oblique crank Z bearing, and carry out automatic compensation adjustment by this radial clearance A, guarantee that release bearing and clutch shaft keep coaxial, solved the problem that causes clutch and release bearing premature wear owing to release bearing and clutch disalignment, the working life of having improved release bearing and clutch.The utility model just can satisfy the function of the outer cover and the wavy spring of conventional construction by an aligning spring, the structure of simplification, and alleviated weight, can reduce manufacture cost.

Description of drawings

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

Wherein: the 1-bearing inner race, 2-aligning spring, the 2-1-card base, the 3-exterior seal ring, the 4-retainer, the 5-steel ball, the 6-bearing outer ring, the 7-inner seal ring, 8-T oblique crank Z bearing, the axial caulking groove of 8-1-, the 8-2-circular groove, the 8-3-skewed slot, 8-4-is caulking groove radially, the 9-wear-resistant sleeve.

Embodiment

See shown in Figure 1, reduced form self-aligning separable bearing of clutch assembly of the present utility model, comprise the bearing unit that bearing inner race 1, bearing outer ring 6, retainer 4 and steel ball 5 constitute, bearing inner race 1 is connected with bearing outer ring 6 by retainer 4 and steel ball 5, for making bearing unit have excellent sealing performance, and on bearing inner race 1 and the bearing outer ring 6 inner seal ring 7 and exterior seal ring 3 are installed.See shown in Figure 1, one side of bearing unit also has T oblique crank Z bearing 8, the T shape end face of this T oblique crank Z bearing 8 has circular groove 8-2, the circular groove 8-2 bottom land of the interior edge face of bearing outer ring 6 and T oblique crank Z bearing 8 joins, aligning spring 2 one sides of ring-type are connected on the T oblique crank Z bearing 8, and the side pressure in addition of aligning spring 2 is connected on the exterior edge face of bearing outer ring 6, the T shape outer peripheral surface of this T oblique crank Z bearing 8 is the conical surface to axle sleeve one side flaring, and T oblique crank Z bearing 8 inversion axis bearing assemblies one side is provided with the skewed slot 8-3 that is used for clamping aligning spring 2, aligning spring 2 of the present utility model can adopt the card base 2-1 more than three, card base 2-1 wraps on the conical surface of T oblique crank Z bearing 8 and is connected in the skewed slot 8-3 of T oblique crank Z bearing 8, installation and processing is convenient, and be provided with the radial clearance A that can regulate the axle center automatically between the cell wall of the external diameter of bearing outer ring 6 and T oblique crank Z bearing 8 circular groove 8-2, this radial clearance A can be controlled between 0.5～1.5mm.When the eccentric force of clutch and release bearing assembly during greater than the elastic force of aligning spring 2, by the radial clearance A between bearing outer ring 6 and the T oblique crank Z bearing 8, release bearing is radially adjusted in the circular groove 8-2 of T oblique crank Z bearing 8, reached clutch and release bearing is coaxial.
