Problems solved by technology

If the retaining ring turns, the retaining ring and the circumferential groove are worn, so the retaining ring shakes and easily comes off the circumferential groove
If the retaining ring breaks away from the circumferential groove, the pressure plate breaks away from the inner cylinder of the shaft, the piston does not work, and the engagement and release actions of the wet multi-disc clutch cannot be performed

Embodiment Construction

[0031] The configuration of a wet multi-plate clutch according to an embodiment of the present invention will be described below.

[0032] figure 1 is an axial sectional view showing the state of main parts of the wet multi-disc clutch according to this embodiment of the present invention.

[0033] Figure 2A By figure 1 An enlarged view of the portion enclosed by circle A in , Figure 2B is the floor plan of the section.

[0034] In addition, in this specification, the axial direction is the axial direction of the wet multi-plate clutch, and the direction perpendicular to the axial direction is referred to as the radial direction or the diameter direction. And, for the sake of illustration, figure 1 When facing the paper, the left side is the axial side, and the right side is the other axial side.

[0035] The wet multi-plate clutch 1 according to the present embodiment is equipped with a hub 5 integrally assembled with the outer peripheral surface of the inner cylindr...

Abstract

The present invention provides a multiplate wet clutch having capability of preventing damage of an axial groove portion formed in an inner cylindrical portion of a shaft. An inner cylindrical portion(3) of the shaft is formed with an axial groove (75) which is opened to a circumferential groove (53) and with which other members of the multiplate wet clutch for regulating movement of a retainingring (55) toward axially on the other side are to be engaged. A pressure plate (35) is formed, on a surface (36b) axially on the other side thereof, with a recessed portion (77) axially opposed to anopening portion (81) of the axial groove (75) through the retaining ring (55).

Description

[0001] The disclosure of the following priority application is incorporated herein by reference: Japanese Patent Application No. 2017-048609. technical field [0002] The present invention relates to a wet multi-plate clutch to be assembled in an automatic transmission of an automobile or the like. Background technique [0003] Automatic transmissions in vehicles such as automobiles are equipped with wet multi-plate clutches used in clutches, brakes, and the like. A wet multi-plate clutch has a configuration in which a plurality of friction plates each formed by attaching a wet friction material to the surface of a core plate as a metal base plate and each as a friction pair material formed of a single plate such as a metal plate A plurality of separator plates are arranged alternately, and the friction plates and the separator plates are pressed against each other by a piston that moves axially and engage or release the engagement with each other to transmit between the clu...
