Description
Technical field
The utility model relates to vibration damper field, particularly relates to a kind of guider of shock absorber.
Background technique
Automobile is through uneven road surface, although the shock-absorbing spring in shock absorbing apparatus can filter out the vibrations on road surface, spring itself still has reciprocal jump, and vibration damper is just being used to the reciprocal jump suppressing this spring.The main structure of vibration damper inserts in cylinder with the piston rod of piston, is full of oil, piston has throttle orifice in cylinder, and the oil in two-part space separated by piston can be complemented each other.The working principle of vibration damper is when vehicle frame and vehicle bridge or when there is relative movement by vibrations between vehicle body and vehicle bridge, piston in vibration damper moves up and down, fluid in vibration damper chamber just flows in another chamber from a chamber through different holes repeatedly, friction now between hole wall and fluid and the intermolecular interior friction of fluid form damping force to vibrations, make thump Conversion of Energy be fluid heat energy, then be dispersed in air by absorber.
Guider is one of strength member in vibration damper, mainly the piston rod be slidably mounted in vibration damper clutch release slave cylinder is play the guiding role, ensure that piston starves smoothness in running, and by the oil-through hole of guider, unnecessary shock absorber fluid being transported in oil storage cylinder in piston movement process, guarantee clutch release slave cylinder is communicated with oil storage cylinder.The guider of prior art is provided with oil outlet, but oil outlet one end is arranged on the side of valve pocket, and well do not locate when using drill bit to process oilhole like this, be easy to the position deviation making oil outlet, reject rate is higher; And the guider of prior art in use, due to long-time use, some oil can be remained at piston rod surface, oil sealing pressure increase can be caused when using like this, and then reduce the working life of guider; And the oil sealing in the guider of prior art is easy to burst because of instantaneous pressure, and then reduce the working life of guider.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of easy to process, reject rate is lower and the guider of shock absorber that working life is higher.
The technological scheme that the utility model adopts is: a kind of guider of shock absorber, comprise guider body, described guider body is provided with oil sealing assembly cavity, valve pocket, for the oil outlet that fluid flows out, for installing the mounting hole of piston rod and being arranged on the lining that mounting hole inwall is slidably matched with piston lever of reducer, described oil sealing assembly cavity and valve pocket include side and bottom surface, described lining is provided with the circular groove that is communicated with oil outlet and encloses projection for being blocked by the hydraulic oil on piston rod and scraping one in circular groove, described oil outlet one end is positioned at outside guider body, the oil outlet the other end is between oil sealing assembly cavity bottom surface and valve pocket side, and be provided with the right angle notch corresponding with oil outlet between the bottom surface of oil sealing assembly cavity and the side of valve pocket, and valve pocket bottom surface is provided with annulus boss, buffer area is provided with between described annulus boss and the perisporium of valve pocket.
Adopt above structure compared with prior art, the utility model has the following advantages: on lining, be provided with a circular groove with protruding, can be wiped off by oil on piston rod easily by projection like this pushes in circular groove, again because circular groove is communicated with oil outlet, these oil be scraped off can be flowed out by oil outlet like this, such use is of a specified duration also can not increase the pressure of oil sealing, makes the working life of guider higher; The bottom surface of oil sealing assembly cavity and the side of valve pocket are provided with the right angle notch corresponding with oil outlet, drill bit can be located by right angle notch when punching with drill bit by this, the position skew produced when avoiding punching, not only makes processing convenient, and greatly reduces reject rate; The bottom surface of valve pocket arranges annulus boss, and be provided with buffer area between annulus boss and the perisporium of valve pocket, well can prevent oil sealing from bursting because of the surge pressure being subject to moment like this, the working life of guider is improved.
As preferably, described circular groove is communicated with oil outlet and refers to, described oil outlet side is provided with branch's oilhole, and described circular groove is communicated with branch oilhole.Such setting, can better import to the hydraulic oil scraped off from piston rod in oil outlet.
As preferably, the cross section of described annulus boss is isosceles trapezoid, and is connected by cambered surface between upper end face with two central planes.It is comparatively large that buffer area is set like this, can better prevent oil sealing from bursting because of the surge pressure being subject to moment, and be connected by cambered surface, can prevent from hurting hand when installing like this.
As preferably, the diameter of described branch oilhole is identical with the width of circular groove.Such setting can reach good Oil Guide effect, and less to the intensity effect of guider.
As preferably, the surface of described projection is cambered surface.Less on the impact of piston rod itself when being arranged on the hydraulic oil scraped on piston rod like this, can not piston rod be damaged.
