Description
Technical field
The utility model relates to automobile absorber field, particularly a kind of combined piston for automobile absorber.
Background technique
The Main Function of automobile absorber is when vehicle body and car sedan-chair or when there is relative movement by vibrations between wheel and vehicle body, piston in vibration damper moves up and down, and the pressure oil in vibration damper just flows in shock absorber oil storage cylinder from vibration damper clutch release slave cylinder through different throttle orifices repeatedly.Friction now between hole wall and hydraulic oil and the intermolecular interior friction of hydraulic oil form damping force to vibration, make automobile vibrational energy be converted into fluid heat energy, then are dispersed in air by absorber.The size of damping force is relevant with factors such as oil flow, oil passage sectional areas.The vibration damper valve seat bottom clutch release slave cylinder is arranged on together with the shock absorber piston that the automobile absorber of prior art comprises vibration damper clutch release slave cylinder, be linked in oil storage cylinder outside vibration damper clutch release slave cylinder, match with vibration damper clutch release slave cylinder.The bottom surface of shock absorber piston and top are provided with interval notch and the relative hydraulic oil channel that misplaces, and are provided with the center hole installing piston rod at the center of piston only; Piston only is also provided with the throttle orifice axially communicated, is equipped with valve block at the end face of piston only and bottom surface; The valve block of both ends of the surface is all socketed on the piston rod, is coordinated the mistake oil mass regulating throttle orifice by piston only two ends valve block with throttle orifice sequence, to reach the object of vibration damper damping shock absorption.The piston of the automobile absorber of prior art is generally the iron-based powder metallurgy parts of integral molding, and beat by machining the Functional Requirement that inclined hole meets oil outlet again after shaping, cost is higher.The shock absorber piston combinationally used after although some mould-formings have also appearred in market, but the bit combination precision between two splits is difficult to ensure, and oil through when restoring normally runs through the both ends of the surface of piston, in the process of high speed operation, the lubrication effect of piston and piston rod is unsatisfactory, easily produces heating and wearing and tearing, damping effect can be caused to be deteriorated, travelling comfort is good not, and greatly reduces the working life of vibration damper entirety.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of oil-feed and fuel-displaced mode more reasonable, the combined piston for automobile absorber of better lubrication can be played.
The technical scheme in the invention for solving the above technical problem is: a kind of combined piston for automobile absorber, comprise piston only, described piston only is made up of first piston body and the second piston body integral type drive fit, the second described piston body vertically offer from lower end surface multiple for compressing time oil-feed the first oil through, described first piston body is circumferentially provided with multiple through first piston body sidewall and the second oil through of cross setting, and the lower end of the second described oil through is connected with the first corresponding oil through; 3rd oil through of oil-feed when described first piston body vertically offers for restoring from upper-end surface, the second described piston body is circumferentially provided with the 4th oil through that the 3rd multiple with corresponding oil through is connected, and the lower end of the 4th described oil through is oblique runs through the second described piston body sidewall.
Compared with prior art, the utility model has the advantage of: this combined piston being used for automobile absorber is made up of first piston body and the second piston body integral type drive fit, second piston body vertically offer from lower end surface multiple for compressing time oil-feed the first oil through, first piston body is circumferentially provided with multiple through first piston body sidewall and the second oil through of cross setting, and the lower end of the second oil through is connected with the first corresponding oil through; 3rd oil through of oil-feed when first piston body vertically offers for restoring from upper-end surface, second piston body is circumferentially provided with the 4th oil through that the 3rd multiple with corresponding oil through is connected, and the lower end of the 4th oil through is oblique runs through the second described piston body sidewall.Like this, when compressing, hydraulic oil is from the second piston body lower end surface oil-feed, and fuel-displaced from first piston body sidewall, then from the upper-end surface oil-feed of first piston body during recovery, and oblique fuel-displaced from the second piston body sidewall, oil-feed and fuel-displaced mode more reasonable, better lubrication can be played, not easily produce heating and wearing and tearing, cause good damping effect, travelling comfort is good, and substantially increases the working life of vibration damper entirety.
As preferably, the second described piston body upper-end surface is provided with the positioning block for matching with a certain second oil through.
Be provided with angle α between the second described oil through two side, and described angle α is 20 ~ 25 °.
The described skew wall of the 4th oil through lower end and the angle β of vertical direction are 20 ~ 30 °.
The first described oil through, the second oil through, the 3rd oil through and the 4th oil through are 5.
The first described oil through and the 3rd oil through spaced apart along the circumference of the second described piston body; The second described oil through and the 4th oil through spaced apart along the circumference of described first piston body.
