Problems solved by technology

On the contrary, in the double-sided sticking structure, since the driven side clutch plate is sandwiched by the clutch lining from both sides, there is a problem that when the clutch is engaged, especially when the clutch plate is slipped and the torque is transmitted Next, the heat generated by sliding will be transferred from both sides in the radial direction and axial direction to the central part, and the sliding heat will gather in the central part of the driven side clutch plate, causing the temperature of the driven side clutch plate to rise significantly

Embodiment Construction

[0039] Next, a case where the wet multi-plate clutch according to the first embodiment of the present invention is applied to a so-called one-motor two-clutch hybrid vehicle will be described. figure 1 is a schematic representation of a so-called one-motor-two-clutch type hybrid vehicle drive plate, the reference numeral 10 represents an engine (internal combustion engine) as a driving source of the vehicle, and reference numeral 12 represents a clutch for selectively transmitting the power of the engine 10 ( Hereinafter referred to as the engine clutch), the symbol 14 represents the driving electric motor (which also functions as a charging generator) as the driving source of the vehicle, the symbol 16 represents a planetary gear type forward and reverse switching device, and the symbol 18 represents a belt type continuous In a transmission (hereinafter referred to as a CVT), reference numeral 20 denotes a differential (Japanese: ディファレンシャル), and reference numeral 22 denotes dr...

Abstract

The present invention relates to a wet multi-plate clutch that can be used in car transmissions, etc. and the purpose is to achieve improvement of thermal characteristics (making temperature distribution more uniform). A clutch pack 50 comprises multiple drive plates 52 and multiple driven plates 54. Clutch facing 55 is fixed on one surface of the drive plates 52 and a circular groove 58 is formedover the entire perimeter of the opposite surface of the drive plate. Clutch facing 56 is fixed to one surface of the driven plates 54 and a circular groove 59 is formed over the entire perimeter ofthe opposite surface of the driven plate. During clutch engagement: the respective surfaces of the drive plates 52 and 54, in which the circular grooves 58 and 59 are formed, that slide with respect to the clutch facings 56 and 55 are clamped between adjacent clutch facings 55 and 56, making axial direction heat conduction discontinuous; clutch oil pools in the circular grooves 58 and 59 and heatconduction in the radial direction is made discontinuous in said areas; the concentration of frictional heat in the central section is prevented; and clutch plate temperature distribution is made moreuniform.

Description

technical field [0001] The present invention relates to a wet multi-plate clutch, especially a wet multi-plate clutch that can be used in a transmission of an automobile or the like. Background technique [0002] A wet multi-plate clutch used in a transmission of an automobile, etc. is configured by alternately arranging a driving side clutch plate (driving plate) and a driven side clutch plate (driven plate) in the axial direction, wherein the driving side clutch plate is driving The side cylindrical member (clutch drum, etc.) rotates integrally with the driving side cylindrical member (clutch hub, etc.) and freely slides in the axial direction. wheel, etc.) rotates integrally with the driven-side cylindrical member and freely slides in the axial direction, and a clutch facing (Japanese: clutch facing) made of friction material is arranged on the adjacent drive Between the side clutch plate and the driven side clutch plate, and always supply clutch oil between the clutch p...
