Abstract
The utility model discloses a buffer block, which comprises a cylindrical elastic body, wherein the upper surface, the lower surface and the inner wall of the elastic body are provided with a plurality of salient points. The buffer block has a simple structure and good buffering and exhausting effects, is convenient to manufacture, and contributes to prolonging the service life of the buffer block and enhancing the driving comfort and stability.
Description
Technical field
The utility model relates to the bumper and absorbing shock technical field of automobile, refers in particular to a kind of buffer stopper in the buffer damping mechanism.
Background technique
Automobile is different in the different road conditions suffered vibration force of going, and goes for good road surface, and the occupant feels comfortable in order to make to take, and often hopes that the rigidity of vehicle damping mechanism is low; And the fierceness that causes for the cope with bad road conditions shakes, and the occupant hopes to improve the rigidity of damper mechanism again.To this opposite seeking for, automobile industry usually uses buffer stopper to improve the travelling comfort and the stability of driving.
Buffer stopper commonly used at present is an injection molding process, makes as main raw material(s) with rubber in the past, generally adopts polyurethane material to make buffer stopper at present.Buffer stopper is main to be assembled with shock absorber piston rod, also has after the part buffer stopper directly be contained in afterwards on the vehicle body.Buffer stopper contacts with liquid storage cylinder cap with shock absorber piston rod, is used for cushioning the impact and the spacing effect of wheel that are delivered to vehicle body.But still lack friction on the existing buffer stopper structure, buffering and exhaust effect are not ideal enough, are prone to abnormal sound in the compression process.
The day for announcing is that the patent that October 14, notification number in 2009 are CN201325297Y has proposed a kind of buffer stopper; Buffer stopper offers the center hole that can be placed on the piston lever of reducer; Particularly buffer stopper is the frustum shape of hollow with the end that the shock absorber sealing lid contacts, and its surface has groove.This model utility helps improving the working life of buffer stopper and avoiding the buffer stopper stiffness curve to change with the increase of temperature; And can reduce the buffer stopper noise that its internal gas produced when being compressed; But cushioning effect is still not enough to some extent; Need further to improve, frictional force is big not enough, is prone to abnormal sound in the compression process.
Summary of the invention
Existing technology automatic buffer block buffering and exhaust effect are not ideal enough in order to solve, be prone to the problem of abnormal sound in the compression process; The utility model provides a kind of buffer stopper; The upper surface of buffer stopper, lower surface and inwall are equipped with a lot of small salient points; Can effectively discharge air and increase frictional force that compression produces, prevent that buffer stopper is loosening.
The technological scheme that the utility model adopted is: a kind of buffer stopper, comprise columnar elastic body, and elastic body's upper surface, lower surface and inwall are provided with several salient points.Buffer stopper upper surface, lower surface and inwall all have a lot of little salient points; Wherein, The salient point of upper surface and lower surface mainly is when buffer stopper is compressed; The liquid storage cylinder cap collision of the upper bracket of the spring of buffer stopper and upper surface and lower surface, the air that produces in the compression can be effectively discharged in the gap between the small salient point, reduces the abnormal sound that produces in the collision process; The salient point of buffer stopper inwall mainly be because buffer stopper and piston rod are interference fit, and small salient point can effectively increase frictional force, prevents that buffer stopper is loosening.
As preferably, the elastic body is a cylinder barrel shaped.The elastic body of cylinder barrel shaped is receiving vibration force to do the time spent except the two end part that the big frictional force that receives vibration damping mounting influences, and its internal stress distribution is relatively balanced.
As preferably, the elastic body is the round platform tubular.The elastic body of round platform tubular is easier to realize becoming the purpose of rigidity.
As preferably, elastic body's inwall is provided with the inner groovy of some roads around inwall.
As preferably, inner groovy is divided into several zones with the salient point on elastic body's inwall.The salient point of buffer stopper inwall mainly is present in the non-groove part that buffer stopper and piston rod closely contact, because buffer stopper and piston rod are interference fit, and small salient point can increase frictional force effectively, prevents that buffer stopper is loosening.
As preferably, elastic body's outer wall has the outer groove of some roads around the elastic body.
As preferably, the section of outer groove is trapezoidal.Trapezoidal waveform is out of shape receiving the vibration force effect, can utilize its nonlinear stiffness variation and help the absorption resonance ripple, avoids buffer stopper to damage.
The beneficial effect of the utility model is: simple in structure, easy to make, buffering and good exhaust effect in the working life that helps improving buffer stopper, improve the travelling comfort and the stability of driving.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model;
Fig. 2 is an A-A sectional view partial schematic diagram among Fig. 1.
Among the figure, 1-elastic body, 2-upper surface, 3-lower surface, 4-inwall, 5-inner groovy, the outer groove of 6-, 7-salient point.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.
Embodiment 1
As shown in Figure 1, a kind of buffer stopper comprises the elastic body 1 of round platform tubular, all irregular dozens of salient point 7 that is distributed with on elastic body 1 upper surface 2, lower surface 3 and the inwall 4.As shown in Figure 2, have the inner groovy 5 of three roads on elastic body 1 the inwall 4 around inwall, the salient point 7 on the inwall 4 is divided into five zones by three road inner groovies 5, and elastic body 1 outer wall has the outer groove 6 of three roads around elastic body 1.
Buffer stopper upper surface, lower surface and inwall all have a lot of little salient points; The salient point of upper surface and lower surface mainly is when buffer stopper is compressed; The liquid storage cylinder cap collision of the upper bracket of the spring of buffer stopper and upper surface and lower surface; Small salient point can be discharged the air that produces in the compression effectively, reduces the abnormal sound that produces in the collision process; The salient point of buffer stopper inwall mainly be because buffer stopper and piston rod are interference fit, and small salient point can increase frictional force effectively, prevents that buffer stopper is loosening.
Embodiment 2
Elastic body 1 is a cylinder barrel shaped among the embodiment 2, and elastic body 1 inwall 4 is provided with the inner groovy 5 of five roads around inwall, and elastic body 1 outer wall has the outer groove 6 of five roads around elastic body 1, and all the other are identical with embodiment 1.
