Abstract
The utility model discloses a reinforced bumper block, overcomes the defect that the bumper block is apt to be fatigued and damaged in the prior art, and provides a reinforced antifatigue bumper block which comprises a cylindrical elastic body. At least one groove which surrounds the cylindrical elastic body is arranged on the external circumference of the cylindrical elastic body. At least two reinforcing ribs are transversely and evenly arranged in the groove. Since the corrugated groove is arranged on the external surface of the bumper block, the variable stiffness can be realized to adapt to all kinds of road situations; and since the reinforcing ribs are arranged in the corrugated groove on the external surface of the bumper block, the extreme distortion of the corrugated groove during the compression of the bumper block can be limited to prevent local parts from being fatigued and damaged at an early stage.
Description
Technical field
The utility model belongs to the vehicle chassis technology field, is specifically related to a kind of bump rubber structure.
Background technology
Automobile travels on the road surface of different stage, and suffered vibratory force differs widely, and for travelling in good road surface, the occupant feels comfortable in order to make to take, and often wishes that the rigidity of vehicle damping mechanism is low; And the fierceness that causes for the cope with bad road conditions shakes, people wish to improve the rigidity of damping again, at this opposite seeking for, there is the inventor to propose a kind of buffer of damper block structured solution that becomes rigidity, Chinese patent notification number CN 201143882Y for example, name is called the utility model patent of " the spacing bump rubber of a kind of bumper ", discloses a kind of bump rubber structure, comprise the bump rubber body, offer the centre hole that can be placed on the piston lever of reducer on this bump rubber body; Wherein, described bump rubber body is the inversed taper platform shape; The sort buffer piece also is provided with the profile of tooth ring structure at its this external surface of frustum, puts a ring stiffener again in profile of tooth ring structure outside.When being subjected to less vibratory force, be easy to generate distortion because the tooth root position rigidity of the frustum small end of bump rubber and profile of tooth ring structure is less, play buffer action; When vehicle generation high vibration, bump rubber continues big end of frustum and the ring stiffener stress deformation that downward compressive deformation causes bump rubber, thereby plays bigger buffering effect.The deficiency that the sort buffer piece exists is: in the described organization plan because of there being a ring stiffener on the bump rubber body, bump rubber is when being subjected to big compression, the ring stiffener distortion is less, impel the groove of the profile of tooth ring of bump rubber to increase distortion, easily cause the bottom portion of groove early fatigue of profile of tooth ring to damage after compressing the excess distortion repeatedly, make defective shock absorber.
Summary of the invention
The utility model technical issues that need to address are, overcome the deficiency that the bump rubber fatiguability of prior art damages, and a kind of bump rubber of heavier-duty antifatigue is provided.
The purpose of this utility model is achieved by following technical proposals: a kind of heavier-duty bump rubber, comprise the cylindrical shape elastic body, periphery at cylinder body is provided with the groove around body, at least two strengthening ribs of horizontal uniform setting in the groove of described groove at least one.Strengthening rib is set limits the ultimate deformation amount of bump rubber at compression process medium wave connected in star.
As preferably, described cylindrical shape elastic body is the cylindrical drum shape; The elastic body of cylindrical drum shape is being subjected to vibratory force to do the time spent except the both ends that the big friction force that is subjected to vibration damping mounting influences, and its internal stress distribution is relatively balanced, helps increasing the service life.
As preferably, described cylindrical shape elastic body is the taper barrel shape; The elastic body of taper barrel shape is easier to realize becoming the purpose of rigidity.
As preferably, the section of described waveform groove is a trapezoidal waveform, when trapezoidal waveform is out of shape being subjected to the vibratory force effect, can utilizes its nonlinear stiffness to change and helps the absorption resonance ripple; And can reduce the probability of bottom portion of groove generation stress concentration, avoid the bump rubber early fatigue to damage.
As preferably, the upper bottom surface of described bump rubber is laid with several circular arc cutaway.
The beneficial effects of the utility model are:
1. the outside face at bump rubber is provided with the waveform groove, can realize becoming rigidity to adapt to the road conditions of various grades;
2. in the waveform groove of the outside face of bump rubber, strengthening rib is set, can limits the ultimate deformation amount of bump rubber, prevent that local early fatigue from damaging at compression process medium wave connected in star.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Among the figure, 1. bump rubber body; 2. groove; 3. ring stiffener; 4. strengthening rib.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiments the utility model is further described.
Embodiment: as shown in Figure 1, a kind of heavier-duty bump rubber comprises cylinder barrel shaped elastic body 1, is provided with the groove 2 of bipassage ring around body at the periphery of cylinder body 1, the section of groove 2 is a trapezoidal shape, horizontal uniform two strengthening ribs 4 that are provided with in the groove of groove 2; The section of groove is a trapezoidal shape.
The inside of bump rubber is stepped through hole, have in the endoporus one section can with the piston rod interference fit of bumper, the other position of endoporus and piston rod keep the gap.
The upper bottom surface of bump rubber is laid with 4 and is trapezoidal breach, and being shaped as of breach is trapezoidal.
Be provided with the ring stiffener of a thinner thickness at the middle part of bump rubber, this ring stiffener elastic force is less, can play booster action.
Claims (5)
1. a heavier-duty bump rubber comprises the cylindrical shape elastic body, is provided with at least together around the groove of body at the periphery of cylinder body, it is characterized in that at least two strengthening ribs of horizontal uniform setting in the groove of described groove.
2. heavier-duty bump rubber according to claim 1 is characterized in that, described cylindrical shape elastic body is the cylindrical drum shape.
3. heavier-duty bump rubber according to claim 1 is characterized in that, described cylindrical shape elastic body is the taper barrel shape.
4. according to claim 1 or 2 or 3 described heavier-duty bump rubbers, it is characterized in that the section of described waveform groove is a trapezoidal waveform.
