Abstract
The utility model relates to a hydraulic clutch actuator. The hydraulic clutch actuator comprises a hydraulic cylinder, wherein a piston cavity of which the axis stretches in the back-and-front direction is formed in the hydraulic cylinder; a piston is assembled in the piston cavity in a guide sealing and sliding manner; impurity accumulation tanks are arranged on the wall of the piston cavity and/or on the outer circumferential surface of the piston. Through arrangement of the impurity accumulation tanks arranged on the wall of the piston cavity and/or on the outer circumferential surface of the piston, impurities between the piston and the wall of the piston cavity can be stored in the impurity accumulation tanks without wearing the piston and the wall of the piston cavity, so that the service life of the hydraulic clutch actuator can be ensured.
Description
Technical field
The utility model relates to a kind of hydraulic clutch actuator.
Background technique
At present, clutch actuating mechanism is divided into mechanical type, pneumatic-typed and hydraulic type by the kind of drive, wherein hydraulic clutch actuator has that surface friction drag is little, quality is light, transmission efficiency is high, engage the advantages such as soft, is the direction that automobile industry is first developed.Existing hydraulic clutch actuator is as the hydraulic clutch actuator of the disclosed a kind of AMT of Chinese patent CN102797768A, this clutch actuating mechanism comprises hydraulic cylinder, hydraulic cylinder has the piston cavity that axis extends along fore-and-aft direction, in piston cavity, pilot seal slidable fit has piston, the front end of piston is connected with piston rod, the rear end of piston is connected with the displacement take-off lever arranging with piston coaxial line, on displacement take-off lever, be connected with displacement transducer, on hydraulic cylinder, be provided with the oil inlet and outlet that axis radially extends along hydraulic cylinder, between piston and hydraulic cylinder, be provided with Returnning spring.When actual use, thereby hydraulic oil is entered in piston cavity and is driven piston rod movement to realize respective clutch separation or combination with driven plunger by oil inlet and outlet, and Returnning spring for driving piston, piston rod to reset in the time that hydraulic fluid pressure disappears.The problem that existing this clutch actuating mechanism exists is: in actual use, in hydraulic oil, easily there are some impurity, in the time that these impurity enter into the matching gap between piston and piston cavity wall, can accelerate the wearing and tearing of hydraulic cylinder and piston, affect the working life of clutch actuating mechanism; In addition displacement take-off lever be arranged at piston rear end and with piston coaxial line setting, so just increased the axial length of whole clutch actuating mechanism, be unfavorable for using in some use conditional working environment to axial space.
Summary of the invention
The purpose of this utility model is to provide a kind of piston, the nonabradable hydraulic clutch of hydraulic cylinder actuator.
In order to address the above problem, the technical solution of the utility model is:
Hydraulic clutch actuator, comprise hydraulic cylinder, hydraulic cylinder has the piston cavity that axis extends along fore-and-aft direction, and in described piston cavity, pilot seal slidable fit has piston, on the chamber wall of described piston cavity and/or the outer circumferential face of described piston be provided with impurity and accumulate groove.
Described impurity accumulates the ring that is shaped as of groove.
The front end of described piston is connected with piston rod, on the outer circumferential face of described piston, be also provided with driving groove, the rear side cell wall of described driving groove court gradually from front to back extends away from the axial direction of piston, on described hydraulic cylinder, be provided with mounting hole with the corresponding position of described rear side cell wall, the axis of mounting hole is from front to back gradually towards extending near piston direction, the slidable fit that leads in mounting hole has displacement take-off lever, be positioned at the one end and the described rear side cell wall sliding friction top press fit that on take-off lever, close on described piston, one end away from described piston on displacement take-off lever is provided with displacement transducer.
On the front-end face of described piston, be provided with recess groove forward, the right part of described piston rod is the ball head structure coordinating with described groove transmission,
On described hydraulic cylinder, be provided with in the rear side of described piston the oil inlet and outlet of arranging with described piston coaxial line.
The beneficial effects of the utility model are: the utility model is by the chamber wall in piston cavity and/or on the outer circumferential face of piston, impurity is set and accumulates groove, impurity between the chamber wall of piston and piston cavity can be stored in impurity and accumulate in groove, and can worn piston and the chamber wall of piston cavity, thereby guarantee working life of hydraulic clutch actuator.
Further, in the time that piston moves forward, the rear side cell wall of driving groove can push up presses displacement take-off lever, thereby makes displacement transducer record the displacement of piston, the all sides that are arranged at piston that displacement take-off lever tilts, have reduced the axial length of whole hydraulic clutch actuator.
