Embodiment Construction

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] reference figure 2 In the prior art, the driven disc body 3 has a first hole 3a, the disc hub flange 2 has a second hole 2a, and the first hole 3a and the second hole 2a are axially opposed. Due to the machining error, there is a gap A in the direction of elastic deformation between the first hole 3a on the driven disc body 3 and the second hole 2a on the hub flange 2 ( figure 2 Shown in). The damping spring 4 is clamped and arranged with the first hole 3a on the driven disc body 3 along its own elastic deformation direction, and is arranged with gaps on both sides of the second hole 2b on the disc hub flange 2.

[0030] Combine figure 1 As shown, in this structure, the friction plate 5 transmits the torque outp...

Abstract

The invention provides a driven plate of a clutch and the clutch. The driven plate of the clutch comprises a plate hub, a driven plate body and damping springs, wherein the plate hub and the driven plate body are coaxially arranged. The plate hub comprises a hub core and a plate hub flange coaxially arranged outside the hub core. The driven plate body is provided with a plurality of first holes which are circumferentially distributed. The plate hub flange is provided with a plurality of second holes which are circumferentially distributed. The first holes and the second holes are axially opposite. The damping springs are arranged in the first holes and the second holes and have pre-tightening force. In the elastic deformation direction, the first end of the first type of damping springs abut against the side walls of the first holes, the second end of the first type of damping springs abut against the side walls of the second holes, the first end of the second type of damping springs abut against the side walls of the second holes, and the second end of the second type of damping springs abut against the side walls of the first holes. In the circumferential direction, the force borne by the driven plate body from the first type of damping forces and the force borne by the driven plate body from the second type damping forces are identical in magnitude and opposite in direction.The driven plate of the clutch is free of idle travel, and the resonance phenomenon caused by the idle travel can be eliminated.

Description

Technical field [0001] The invention relates to the technical field of clutches, in particular to a clutch driven disc and a clutch. Background technique [0002] The clutch includes a driven plate and a pressure plate, the pressure plate is connected with the flywheel on the engine, and the driven plate is connected with the input shaft of the gearbox. When the driven plate and pressure plate are engaged, the pressure plate transmits engine torque to the driven plate, and then the driven plate transmits torque to the gearbox; when the driven plate and pressure plate are separated, the torque transmission between the engine and the gearbox is cut off. [0003] reference figure 1 , The existing clutch driven disc includes: a driven disc body 3 and a driven disc hub which are coaxially arranged. The driven disc body 3 is connected with the friction plate 5 through the fixed plate 6, and the friction plate 5 is used to contact a pressure plate provided on the flywheel of the engine. ...
