Abstract
The utility model discloses a buffer of shock absorber, including the buffer block of suit on the damper cylinder piston rod, the cover is equipped with the elasticity spacing ring on the external diameter of buffer block, the elastic deformation volume of buffer block is greater than the elastic deformation volume of elasticity spacing ring, the surface of buffer block is followed the buffer block axis direction is the unsmooth setting of wave, the elasticity spacing ring is located in one of them concave surface that the wave is unsmooth in setting up, the elasticity spacing ring is located the middle part of buffer block, the inner wall of buffer block is followed the axis direction interval of buffer block is provided with a plurality of annular grooves. The utility model discloses simple structure can reduce the injury to the buffer block under abominable road surface transport condition, improve its life, can also satisfy in time or provide in advance the rigidity requirement of corresponding carload demand, finally protects the suspension, has avoided suspension quilt " puncture " and the striking of production.
Description
Technical field
The utility model relates to automotive suspension technical field, is specifically related to a kind of shock absorber of shock absorber.
Background technology
Vibratory force suffered by automobile travels in different road conditions is different, and travel for good road surface, occupant feels comfortable to make to take, and often wishes that the rigidity of vehicle damping mechanism is lower; And the fierceness vibrations caused in order to cope with bad road conditions, occupant wishes again the rigidity improving damping.For this seeking on the contrary, automobile industry usually uses bump rubber to improve traveling comfort and the stability of driving on shock absorber.
Bump rubber is the device that can limit suspension maximum deformation quantity.It alleviates the direct collision of axletree to vehicle frame (or vehicle body), prevents elastic element from producing excessive distortion.When wheel is jumped certain stroke; " punctured " to prevent suspension the shock that causes; bump rubber is in parallel with main elastic element (being generally coil spring) forms the stronger elastic element of a nonlinear degree; be used for limiting suspension travel; while passing to the impact of vehicle body with absorption from wheel; prevent suspension from " being punctured ", and then improve travelling comfort and protection suspension.But under the road conditions that some are severe, wheel skipping to range, be also impact bump rubber, and bump rubber long-term work is on maximum flexibility deformation extent, to there is certain influence the service life of bump rubber, also makes bump rubber easily damage simultaneously.
Utility model content
For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is: how to provide a kind of when severe road traveling, reduces, to bump rubber injury, to improve the shock absorber of the shock absorber in its service life.
In order to solve the problems of the technologies described above, the utility model have employed following technical scheme:
A shock absorber for shock absorber, comprises the bump rubber be sleeved on damper cylinder piston bar, it is characterized in that: the external diameter of described bump rubber is arranged with elastic spacing ring, and the elastic deformation amount of described bump rubber is greater than the elastic deformation amount of described elastic spacing ring.
In the utility model, when journey that wheel slips a line is increased to a certain degree, bump rubber bottom starts contact damping cylinder top.Along with the progressively increase of journey that wheel slips a line, bump rubber along the direction of damper cylinder piston bar along with helical spring compression by compressive deformation, thus bump rubber serves the part impact load absorbing and to pass to from wheel vehicle body, improves vehicle riding comfort.When wheel continues upper jumping, continuations is compressed by bump rubber, and simultaneous buffering block radially expands, and now fractional load is delivered on sheathed elastic spacing ring on it by bump rubber, and elastic spacing ring starts to be out of shape simultaneously.The elastic deformation amount of bump rubber is greater than the elastic deformation amount of elastic spacing ring, and then the distortion of elastic spacing ring and bump rubber limits, avoid it to be in for a long time to be operated on maximum flexibility deformation extent, reduce the injury to bump rubber, improve its service life.
As optimization, the outside face of described bump rubber is the concavo-convex setting of waveform along described bump rubber axis direction, and described elastic spacing ring is arranged in concavo-convex one of them concave surface arranged of described waveform.Bump rubber stressed flexible time, corrugated outside face also can along with prolongation shorten, there will not be the situation of forced breakage, improve the service life of bump rubber.
As optimization, described elastic spacing ring is positioned at the middle part of described bump rubber.Bump rubber is in the process of stress deformation, and in the middle part of it, amplitude of deformation is radially maximum, and the elastic spacing ring be positioned in the middle part of bump rubber can better carry out spacing to bump rubber, improves its service life.
As optimization, the inwall of described bump rubber is arranged at intervals with multiple annular groove along the axis direction of described bump rubber.Bump rubber is in deformation process, and surface can outwards outside distortion except for the outer, and inwall equally also can to internal strain, and annular groove provides a deformation space for inwall, avoids it to damage.
In sum; the beneficial effects of the utility model are: the utility model structure is simple; can under severe road traveling state; reduce the injury to bump rubber; improve its service life; the rigidity requirement that corresponding carload demand is provided in time or in advance can also be met, finally protect suspension, avoid suspension and " punctured " and the shock produced.
