The specific embodiment of the present invention is described in detail.
First embodiment
With reference to Fig. 3, the present embodiment provides a kind of clutch system 10, including: include diaphragm spring 101
Clutch 100；Separate and the clutch operating device 200 engaged for controlling clutch 100.Clutch
Device operating mechanism 200 includes: release bearing assembly 201；Coaxial slave cylinder (Concentric Slave
Cylinder, is called for short CSC) 202.Coaxial slave cylinder 202 includes: guide sleeves 204, has for accommodating
The through hole (mark) of transmission input shaft；The annular piston 203 being sheathed on movably outside guide sleeves 204,
It is positioned at release bearing assembly 201 and is axially distant from the side of clutch 100.
With reference to Fig. 3 and Fig. 4, release bearing assembly 201 includes: support ring 220, vertically with piston 203
Connect；It is sheathed on elastic component 230 outside support ring 220 and ringwise；Release bearing 210.Release bearing
210 have the inner ring 211 and outer ring 212 being coaxially disposed, and between inner ring 211 and outer ring 212
Some rolling elements 213, release bearing 210 is sheathed on outside support ring 220 movably by inner ring 211,
Wherein between inner ring 211 and support ring 220, there is radial clearance, it is allowed to release bearing 210 relative support
Ring 220 moves radially to change the position of its axis, it is achieved self-centering.Outer ring 212 is along clutch
Device 100 axially and diaphragm spring 101 against, diaphragm spring 101 connects at clutch 100 with outer ring 212
During conjunction can synchronous axial system, and inner ring 211 is nonrotational circle, and piston 203 is for by support ring 220
Order about inner ring 211 moving axially along clutch 100.
It should be noted that for nonrotational circle, inner ring 211 refers to that clutch system is non-when normal work
Turning collar, but when clutch system cryogenic conditions (as subzero 30 Celsius～subzero 50 degrees Celsius) under
During operation, the oils and fats in release bearing 210 condenses and causes obstruction, it is possible that outer ring 212 rotates
Time drive inner ring 211 rotate situation.
With reference to Fig. 4, inner ring 211 is provided with axially move closer to one end of clutch 100: radially toward support
Ring 220 protrudes and the first teat 240 of cincture release bearing 210 axis.Support ring 220 is provided with opening
The 221 receiving spaces 222 offered radially toward inner ring 211, have axially opposing sidewall 223 and stop
Block piece 224.First teat 240 stretches in receiving space 222, and and accommodates between space 222 has radially
Gap, so that release bearing 210 can diametrically opposite support ring 220 move.Elastic component 230 is located at appearance
Receive in space 222, and vertically to being located between sidewall 223 and the first teat 240, for first
Teat 240 applies axial elastic force.By elastic force effect, the first teat 240 clutch 100 the most dorsad
Side and stop part 224 against, a definite limitation is played in the position of release bearing 210 by elastic component 230
Effect, it is to avoid release bearing 210 arbitrarily moves, release bearing assembly 201 compact conformation.
With reference to Fig. 4 and Fig. 5, wherein supported by antifriction mode between the first teat 240 and stop part 224
Leaning on, the most antifriction mode refers to reduce the side of the frictional force between the first teat 240 and stop part 224
Formula.This antifriction mode is: stop part 224 axially faces toward the surface-coated of the first teat 240 to be had anti-
Frictional layer 225, this antifriction layer 225 is made up of antifriction material, the first teat 240 and antifriction layer
225 contacts.Antifriction material has relatively low coefficient of friction, it reduces the first teat 240 and stop part
Between 224 against time frictional force.Even, when clutch 100 is in engagement state, clutch
100 apply the biggest axial compressive force along direction C by diaphragm spring 101 to release bearing 210, should
Bigger axial compressive force makes the thrust between the first teat 240 and stop part 224 increase, but due to
The coefficient of friction of antifriction layer 225 is less, and the most compared with prior art, above-mentioned bigger thrust will not
Make the frictional force between the first teat 240 and stop part 224 have to increase by a relatively large margin, the first teat 240
With frictional force between stop part 224 is the least.
So, with reference to Fig. 3 and Fig. 4, when axis and the axis of release bearing 210 of clutch 100
Time eccentric, release bearing 210 has only to overcome less rubbing between the first teat 240 and stop part 224
Wiping power, it becomes possible to move radially so that in the axis of release bearing 210 and clutch 100
On the same line, the self-centering of release bearing 210 becomes easily to realize axis, it is to avoid diaphragm bullet
There is relative slip with release bearing 210 in spring 101, it is ensured that clutch 100 and outer ring 212 synchronize in time
Rotating, the output torque smooth-going of electromotor is transferred to change speed gear box.
Further, compared with prior art, when release bearing 210 self-centering, the first teat 240
With between stop part 224, less frictional force will not produce bigger noise and reduce sound pollution, also avoids
There is torque differences between outer ring 212 and clutch 100, reduce the vibration of clutch system, this changes
It is apt to NVH (Noise, Vibration, Harshness) performance of automobile.And, the first teat 240
Frictional dissipation little, such that it is able to promote release bearing 210 and the service life of support ring 220.It addition,
Frictional force between first teat 240 and antifriction layer 225 reduces, it reduce support ring 220 and
The strength demand of coaxial slave cylinder 202.
For antifriction layer 225, antifriction material can select molybdenum bisuphide or PAEK (PAEK).

224 towards on the surface of the first teat 240；Afterwards, carry out the process that is heating and curing, make molybdenum bisuphide lubricate
Fat strongly adherent is on stop part 224.As a example by PAEK, PAEK is that a kind phenylene ring passes through ether
The polymer that key and carbonyl are formed by connecting, has preferable fatigue durability and wearability.Use PAEK's
The antifriction layer forming method that the forming method of antifriction layer 225 is made with above-mentioned molybdenum bisuphide is similar, no
Describe in detail again.
In addition to the antifriction material of above-mentioned example, it is also possible to select other to have good adhesion and wearability
Antifriction material, make antifriction layer 225.
A kind of variation as antifriction mode, it is also possible to be: axially face toward at the first teat 240
The surface-coated of stop part 224 has antifriction layer；Or, at the first teat 240 and stop part 224 axle
It is coated with antifriction layer to two surfaces in opposite directions.This equally makes release bearing 210 self-centering
Become easy.
Another kind of variation as antifriction mode, it is also possible to be: at the first teat 240 and stop part
Being provided with anti-friction washer (not shown) between 224, anti-friction washer is grippingly set in support ring 220

220 are integrated connection, accordingly, as another variation of antifriction mode, it is also possible to be: inner ring
211 and support ring 220 in wherein one or two use antifriction material make, make the first teat 240
With the frictional force between stop part 224 reduces, and less frictional force also reduces support ring 220
Strength demand, this antifriction material that also intensity can be used relatively low for support ring 220 makes that add can
Can property.As another variation, if the first teat is to be connected on inner ring outside an independent annular element
Formed, now antifriction material can be used to make by this annular element individually designed.Correspondingly, if stop part is
It is connected in support ring outside one independent annular element and is formed, now can design this annular element and use antifriction
Material is made.
In concrete application scenario, the antifriction mode of any of the above-described kind of embodiment can be selected as required to change
