Abstract
The invention discloses a connecting structure of a clutch slave cylinder and a release bearing, which solves the problems of inconvenient operation and poor reliability caused by the connection of the existing clutch slave cylinder and the release bearing through a shifting fork. The technical scheme includes that the clutch wheel cylinder comprises an inner cylinder body, an outer cylinder body and a hydraulic piston pump sleeved between the inner cylinder body and the outer cylinder body, and a release bearing assembly is sleeved on the inner cylinder body, and the rear end of the release bearing assembly is connected with a piston of the hydraulic piston pump. The invention has the advantages of extremely simple structure, high reliability, no need of adjusting the clutch slave cylinder due to the friction of the friction plate of the clutch driven disc, lower cost, small volume and high transmission efficiency.
Description
Technical field
The present invention relates to a kind of car transmissions, specifically the linkage structure of clutch wheel cylinder and release bearing
Background technique
The general hydraulic piston pump that adopts hydraulic drive clutch wheel cylinder is handled in clutch in the car transmissions; Pass through lever (fork) transfer function power between wheel cylinder and the release bearing assembly; The separation that the front end of release bearing assembly is made in clutch refers to that release bearing assembly is fixed on the transmission input shaft through bearing support.Owing to connect through shift fork between clutch wheel cylinder and the release bearing assembly; Efficient is lower; Along with the clutch driven plate friction disc wear, separate and refer to and to move to the speed changer direction that release bearing assembly also need and then move to the speed changer direction; Thereby need often adjustment clutch wheel cylinder, get in touch between referring to guarantee clutch release bearing assembly and clutch separation.This mode is brought problems such as operation inconvenience, poor reliability.
Summary of the invention
To the objective of the invention is in order solving the problems of the technologies described above, to provide that a kind of structure is very simple, good reliability, need not to adjust the clutch wheel cylinder of clutch wheelcylinder piston length and the linkage structure of release bearing.
Technological scheme comprises clutch wheel cylinder and release bearing assembly, and said clutch wheel cylinder comprises inner cylinder body, outer cylinder body and be sleeved on the hydraulic piston pump between inside and outside cylinder body, and said release bearing assembly is sleeved on the inner cylinder body, and its rear end is connected with the piston of hydraulic piston pump.
The leading portion of said inner cylinder body is provided with limited ring.
Be set with pressure spring on the said outer cylinder body, the back end in contact of the front end of said pressure spring and release bearing assembly.
Said pressure spring is with dust-proof cover outward; The dustproof two ends of putting are provided with the pressure spring front end and are connected or preceding retaining ring that contacts and the back retaining ring that is connected or contacts with the pressure spring rear end, the back end in contact or the clamping of said preceding retaining ring and release bearing assembly or be connected.
The inventor furthers investigate the annexation of clutch wheel cylinder and release bearing assembly; And through repeatedly experiment discovery; When the clutch driven plate friction disc wear, separate that refer to can be when the speed changer direction moves, causing and must regulating clutch wheelcylinder piston length is that non-coaxial position concerns and the existing of link fork between clutch wheel cylinder and the release bearing assembly with the reason that adapts to the release bearing assembly displacement; When therefore cancelling fork; Therefore must make the total coaxial setting that is connected of clutch wheel cylinder and release bearing, consider release bearing assembly directly is sleeved on the inner cylinder body of clutch wheel cylinder, end face directly is connected with piston between inside and outside cylinder body thereafter.The separation that front-end face is still made in clutch refers to.Like this; When the clutch driven plate friction disc wear; Separate that refer to can be when the speed changer direction moves, act on and separate the release bearing assembly that refers to and piston under the effect that separates the power that refers to vertically directly conduction and come, the active force that also can overcome pressure spring and hydraulic pressure is axially corresponding mobile to the speed changer direction thereupon along inner cylinder body; Need not to adjust separately the clutch wheel cylinder like this, can guarantee that also clutch release bearing assembly and clutch separation get in touch between referring to.
Further, through the pressure spring that is provided with, utilize the reaction force to its compression, the separation that fitting piston makes the front end of release bearing assembly make in clutch all the time refers to, further guarantees release bearing assembly and the contact condition that separates finger.Be covered with dust-proof cover on the said pressure spring, except that playing dustproof effect, can also be spacing for pressure spring active force vertically.
The present invention is with the clutch wheel cylinder and release bearing assembly is integrated and one; Complicated connected elements such as bearing support, fork have been cancelled; Installation and maintenance are more easy; What is more important need not because of the problem of clutch driven plate friction disc wear piston rod to be adjusted repeatedly, and is time saving and energy saving, improved the safety reliability of clutch for clutch control greatly.The advantage that the present invention has is simple in structure, cost is lower, volume is little, transmission efficiency is high.

Wherein, 1-outer cylinder body, 2-dust-proof cover, 3-back retaining ring, 4-pressure spring, 5-preceding retaining ring, 6-release bearing assembly, 7-limited ring, 8-inner cylinder body, 9-hydraulic piston pump, 10-clutch wheel cylinder, 11-piston.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further explained:
With reference to Fig. 1 and Fig. 3; Be provided with hydraulic piston pump 9 between the inner cylinder body 8 of clutch wheel cylinder 10 and the outer cylinder body 1; Also be with the pressure spring 4 that is closed in the dust-proof cover 2 on the said outer cylinder body 1; The two ends of said dust-proof cover 2 be provided with pressure spring 4 before end in contact (or connection) preceding retaining ring 5 with the back back retaining ring 3 of end in contact (or connection) of pressure spring 4, said dust-proof cover 2 is deformable material (like a rubber etc.), can be with the compressive strain of pressure spring 4 corresponding deformation; Also be with release bearing assembly 6 on the inner cylinder body 8 of clutch wheel cylinder 10; The ear end face of said release bearing assembly 6 is connected with the piston 11 of hydraulic piston pump 9, and while and preceding retaining ring 5 clampings (or connection), and the leading portion of said inner cylinder body 8 also is provided with limited ring 7.
During installation; The existing mounting type of clutch wheel cylinder 10 is constant; Can be through on the housing that is bolted to speed changer, when install separate refer to (not shown) after, the front end that under the effect of pressure spring 4, makes release bearing assembly 6 all the time refers to the state that keeps in touch with separating.
With reference to Fig. 1, when hydraulic pressure in hydraulic piston pump 9, make the piston 15 of hydraulic piston pump 9 directly promote release bearing assemblies 6, release bearing assembly 6 is directly conducted to thrust vertically to separate and refers to, realizes that clutch separates.
With reference to Fig. 2; Wear and tear and work as the clutch driven plate friction plate; Separate and refer to that meeting is when speed changer direction (the back extreme direction of release bearing assembly 6) moves; The active force that release bearing assembly 6 and piston 11 also overcome pressure spring 4 and hydraulic pressure moves to same direction; Simultaneously the front end of release bearing assembly 6 still can keep and the contact condition that separates finger under the active force of pressure spring 4, thereby the whole process of clutch driven disc friction disc wear truly of realizing need not adjusted the purpose of clutch wheel cylinder fully.
