Furthermore, the wave spring is provided with a positioning convex tooth matched with the tooth socket on the central sleeve.

Furthermore, the wet clutch with the auxiliary separation structure further comprises an outer cover, a gear and a cover plate, wherein the gear is located between the end face of the outer cover and the cover plate, the outer cover and the cover plate are riveted into a whole through a riveting column, a through hole is formed in the gear, a supporting sleeve is arranged in the through hole, and the steel supporting sleeve is sleeved on the riveting column.

The utility model has the advantages that:

1. the utility model discloses wet clutch with supplementary isolating construction, when the clutch separation, pressure disk terminal surface throw off the friction disc, and wave spring can promote initiative friction disc and the driven friction disc that the center sheathes and remove along the axis, so can accelerate initiative friction disc and driven friction disc along axial separation to cut off power fast.

The wet clutch does not change the structure of the driven friction plate, the wave spring is convenient to install, and compared with the existing wet clutch which adopts the spiral spring to assist the driving friction plate and the driven friction plate to separate, the wet clutch has the advantages of simpler structure, higher assembly efficiency and lower manufacturing cost.

2. The utility model discloses wet clutch with supplementary separation structure, the last location dogtooth of its wave spring can prevent that wave spring and center sleeve from taking place relative rotation when the clutch separation, can also avoid wave spring to take place radial drunkenness simultaneously to can avoid wave spring to produce the problem of abnormal sound because of the drunkenness collision.

3. The utility model discloses wet clutch with supplementary isolating construction, it has cancelled the projection on the current dustcoat, and the steel supports the direct suit of cover on the rivet, has increased the intensity of connecting portion, and the steel can not appear damaging when supporting cover and gear contact. Meanwhile, the steel support sleeve is small in size and small in occupied space, and a larger space can be reserved for arranging the buffer spring in the circumferential direction of the outer cover.

Detailed Description

The invention is further described with reference to the following figures and examples.

As shown in fig. 2, the wet clutch with the auxiliary separating structure in this embodiment includes a center sleeve 1, a pressure plate 2, a driving friction plate 3 and a driven friction plate 4, the driving friction plate and the driven friction plate are sequentially sleeved on the center sleeve, the driving friction plate is one more than the driven friction plate, the first driving friction plate is attached to the end surface of the center sleeve, and the last driving friction plate is attached to the end surface of the pressure plate. The wet clutch with the auxiliary separation structure in the embodiment further comprises a wave spring 5, and the crest part and the trough part of the wave spring respectively abut against the end face of the central sleeve and the end face of the first driven friction plate.

When the clutch is separated, the end face of the pressure plate is separated from the friction plate, a separation gap for separating the driving friction plate from the driven friction plate occurs between the pressure plate and the center sleeve, and the wave spring pushes the driving friction plate and the driven friction plate on the center sleeve to move along the axis, so that the driving friction plate and the driven friction plate can be accelerated to be separated along the axial direction, and power is cut off rapidly.

As a modification of the above embodiment, the wave spring 5 is provided with a positioning convex tooth 501 which is matched with the tooth socket on the central sleeve.
