Abstract
The utility model provides a hydraulic main cylinder of an anti-bias wearing clutch for an automobile, which belongs to a hydraulic main cylinder of a clutch for automobile transmission systems. The interior of a main cylinder (1) is provided with two coaxial step-shaped column holes; a guide sleeve (10) of a piston of the main cylinder is arranged in the column hole (16) with a greater diameter in the main cylinder (1); the column hole (15) with a smaller diameter in the main cylinder (1) and a column hole (17) in the guide sleeve of a piston of the main cylinder form a working cavity of the piston (6) of the main cylinder together. When the main cylinder works, the piston (6) of the main cylinder moves right and left in the working cavity; the disadvantageous affect of the bias wearing caused by lateral force on the working surface of the inner cavity of the main cylinder can be prevented through the guide sleeve of a piston of the main cylinder, and the earlier damage can be avoided; the working reliability of the transmission system of the automobile is improved, and the service life of the hydraulic main cylinder of the clutch is extended; the hydraulic main cylinder of an anti-bias wearing clutch for an automobile is suitable for the hydraulic main cylinder of the clutch of the automobile transmission system.
Description
Technical field: the utility model relates to the clutch hydraulic pressure master cylinder in the car transmissions, and particularly a kind of automobile is with preventing eccentric wear clutch hydraulic pressure master cylinder.
Background technique: in the transmission system of present various different automobile types at home and abroad, except part dress automatic transmission case, do not need outside the vehicle of clutch, there is other vehicle of larger proportion to install and use the clutch hydraulic pressure master cylinder, because structural reason all can be subjected to the harmful effect of lateral force inevitably when work, produce the eccentric wear phenomenon, tend to cause the inner working face premature wear of clutch hydraulic pressure master cylinder, thereby leakage of oil or failure of removal occur.。
Summary of the invention: the purpose of this utility model is to provide a kind of automobile with preventing eccentric wear clutch hydraulic pressure master cylinder, utilize this master cylinder to avoid or alleviate the adverse effect of eccentric wear phenomenon greatly, thereby improve the working life and the functional reliability of clutch hydraulic pressure master cylinder the master cylinder inner working face.
Formation of the present utility model: form by Master cylinder body, return spring, return spring retainer, liquid outlet opening, master cylinder piston apron, master cylinder piston, packing ring, master cylinder connecting link, circlip, master cylinder piston guide sleeve and Sealing, there is the stepped shaft cylindrical hole of two concentrics the inside of Master cylinder body 1, master cylinder piston guide sleeve 10 is installed in the bigger cylindrical hole 16 of Master cylinder body 1 inside diameter, the cylindrical hole 17 common active chambers of forming master cylinder pistons 6 of 15 of less cylindrical holes of Master cylinder body 1 inside diameter and master cylinder piston guide sleeve 10 inside.
Compared with the prior art, the force analysis of the utility model according to the time to the structure of original clutch hydraulic pressure master cylinder and work, structure to former master cylinder make a big improvement, and has redesigned and increased newly a critical component-master cylinder piston guide sleeve that mainly bears lateral force.This master cylinder piston guide sleeve can slow down or avoid the harmful effect to working surface in the master cylinder of the eccentric wear that produces because of lateral force greatly, thereby has improved working life of the present utility model and functional reliability.
Description of drawings: accompanying drawing is the utility model structural representation.
Among the figure 1, Master cylinder body, 2, liquid outlet opening, 3, return spring, 4, return spring retainer, 5, the master cylinder piston apron, 6, master cylinder piston, 7, packing ring, 8, master cylinder connecting link, 9, circlip, 10, master cylinder piston guide sleeve, 11, Sealing, 12, Sealing, 13, compensate opening, 14, by-pass hole, 15, cylindrical hole, 16, cylindrical hole, 17, cylindrical hole.
Embodiment: as shown in the figure, there is the stepped shaft cylindrical hole of two concentrics the inside of Master cylinder body 1, master cylinder piston guide sleeve 10 is installed in the bigger cylindrical hole 16 of Master cylinder body 1 inside diameter, the cylindrical hole 17 common active chambers of forming master cylinder pistons 6 of 15 of less cylindrical holes of Master cylinder body 1 inside diameter and master cylinder piston guide sleeve 10 inside, during master cylinder work, master cylinder piston 6 is move left and right in this active chamber.
The liquid outlet opening 2, compensate opening 13 and the by-pass hole 14 that are communicated with cylindrical hole 15 are arranged on Master cylinder body 1, return spring retainer 4 and master cylinder piston apron 5 are installed on the master cylinder piston 6 in the cylindrical hole 15 in Master cylinder body 1, and suit return spring 3, master cylinder connecting link 8 is connected with master cylinder piston 6 and is connected with master cylinder piston guide sleeve 10 with circlip 9 by packing ring 7, and Sealing 11 and 12 are housed on master cylinder piston guide sleeve 10.
Claims (1)
1. an automobile is with preventing eccentric wear clutch hydraulic pressure master cylinder, by Master cylinder body, return spring, the return spring retainer, liquid outlet opening, the master cylinder piston apron, master cylinder piston, packing ring, master cylinder connecting link, circlip, master cylinder piston guide sleeve and Sealing are formed, it is characterized in that: there is the stepped shaft cylindrical hole of two concentrics the inside of Master cylinder body (1), master cylinder piston guide sleeve (10) is installed in the bigger cylindrical hole (16) of Master cylinder body (1) inside diameter, and the less cylindrical hole (15) of Master cylinder body (1) inside diameter is then formed the active chamber of master cylinder piston (6) jointly with the cylindrical hole (17) of master cylinder piston guide sleeve (10) inside.
