Abstract
The utility model refers to a vehicle clutch booster, which includes a shell (1), a master cylinder (4) installed inside the shell (1), a vent hole (10) on side wall of the master cylinder (4), a main piston (7) installed in the master cylinder (4), a small support ring (8) and a seal ring (9). The utility model is characterized in that the small supporting ring (8) and the seal ring (9) are equipped on the radial circle of the main piston (7). A vehicle clutch booster of the utility model prevents the end of the main piston from generating a radial bias ensures the smooth operation and the uniform radial pressing to the seal ring, reduces the abrasion, guarantees the airtightness of the oil and the air between the master cylinder and cylinders, and effectively increases the reliability and stability of the product.
Description
Technical field
The utility model relates to a kind of work-saving device of autoclutch, is specifically related to a kind of cylinder forward type automatic clutch servo-unit.
Background technology
At present, the structure of cylinder forward type automatic clutch servo-unit comprises housing, master cylinder that is provided with in the housing and following oil cylinder, the separate cavities that between master cylinder and following oil cylinder, is provided with, with housing through screw retention bonded assembly cylinder, the bulb push rod of the push rod fork assembly that passes cylinder and be connected with main piston in being arranged on master cylinder, the little support ring that sets gradually at the cavity inner wall of the master cylinder of housing and cylinder connection, seal ring, the air bleed hole that is provided with at the sidewall of master cylinder, be arranged on the cylinder piston in the cylinder, and seal ring that on cylinder piston, is provided with and big support ring; Its weak point is: in the round action that main piston in master cylinder and the cylinder piston in the cylinder carry out at the same time, be arranged on big support ring on the cylinder piston then with respect to the ramuscule pushing out ring back and forth movement that is fixed in the master cylinder, run to the position, middle and lower part of cylinder when cylinder piston, the unsupported end of main piston is positioned with influence in master cylinder, in addition since main piston and cylinder piston in the action that promotes push rod fork assembly load, the direction of its interaction force not exclusively is axial, main piston can be support with bulb push rod junction by an end of the fuel feed hole of master cylinder, in the tolerance clearance scope of itself and master cylinder, produce radially moving partially, make radially pressurized inequality of little support ring and seal ring, when main piston is done prolonged and repeated ballistic motion in master cylinder, be easy to make sealing circle premature wear, cause high pressure gas in the cylinder that the string of master cylinder is leaked or master cylinder in hydraulic oil the string of cylinder is leaked, make the separation difficulty of power-transfer clutch, even produce potential safety hazard.Also there be the ramuscule pushing out ring place of employing on master cylinder to set up seal ring and come enhanced leaktightness, but fail fundamentally head it off.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, oil, the automatic clutch servo-unit that gas tightness is good.
The purpose of this utility model is achieved in that a kind of automatic clutch servo-unit, a kind of automatic clutch servo-unit, comprise housing, the master cylinder that is provided with in the housing, the air bleed hole that is provided with at the sidewall of master cylinder, be arranged on main piston, little support ring and seal ring in the master cylinder, it is characterized in that: described little support ring and described seal ring are arranged on the radial circumference of described main piston.
Above-mentioned little support ring and described seal ring are separately positioned in the little circular groove and big circular groove of fuel feed hole one side end that leans on described master cylinder on the described main piston.
Above-mentioned seal ring is V-type or the Y type or the O RunddichtringO of lips mouth.
As required, the described seal ring that is arranged on the above-mentioned main piston can be more than 1, also above-mentioned seal ring can be arranged on the either side or the both sides of described little support ring, it is good wherein with the both sides at described little support ring 1 described seal ring being set respectively, when adopting y-type seal ring, the lip of 2 y-type seal rings can be towards same direction, also can be towards opposite sense
Above-mentioned air bleed hole be arranged on described master cylinder by on the wall of described fuel feed hole one side, and described air bleed hole be positioned at when the end of described main piston be in apart from the nearest position of the described fuel feed hole of described master cylinder, this end outermost be provided with by the nearest described seal ring of described fuel feed hole or the outside of described little support ring.
The utility model is owing to be arranged on the end of leaning on the fuel feed hole of master cylinder on the main piston with little support ring and seal ring, in the round action that main piston and cylinder piston carry out simultaneously, the little support ring that is arranged on the main piston then moves simultaneously with the big support ring that is arranged on the cylinder piston, it is radially moving partially to have avoided the main piston end to produce, make it to operate steadily, radially even, the wearing and tearing minimizing of pressurized of seal ring, guarantee the leak tightness of oil, gas between master cylinder and the cylinder, improved reliability of products and stability effectively.
