A pressing assembling and detaching manner of the buffering block is changed, the structure is simple and the cost is low; the abnormal sounds generated in a working process of the buffering block are effectively reduced through design characteristics of a groove and the lug boss on the buffering block, the initial rigidity of the buffering block is reduced, and the comfort performance of sitting in an automobile is improved.
Description
Technical field
The present invention relates to a kind of bump rubber, particularly relate to a kind of suspension buffer block assembly.
Background technology
Suspension buffer block is a kind of vibration isolator, and Main Function is the vibration reducing automobile suspension system, the rigid collision avoided suspension system because of elastic deformation and produce between other parts, and plays the effect of restriction suspension range.Rubber and steel plate are mainly connected as one by sulfuration by existing bumper-mounting structure, then are assemblied on vehicle frame or other positions by bump rubber vulcanization member with bolt and nut.
In making proof procedure, there is following problem:
(1) bump rubber and steel plate sulfide, and are bolted on vehicle frame, add vulcanization process and bolt part, add bump rubber cost.
(2) bump rubber is owing to being bolted, and bump rubber intermediate demand opens a larger circular hole, and when being unfavorable for spacing, the rigidity of needs realizes.
(3) has larger circular hole in the middle of bump rubber, reduce bump rubber fatigue life, be unfavorable for stability when bump rubber compresses.
Summary of the invention
The technical problem to be solved in the present invention is, buffer block structure for prior art is complicated, the problem of the abnormal sound produced in high expensive, working process and the initial insufficient rigidity of bump rubber, one is provided to be applicable to automotive suspension, under can guaranteeing to meet the prerequisite of automobile suspension bouncing stroke, effectively can realize the simple and easy Assembly And Disassembly of bump rubber, ensure the bump rubber assembly of the comfort property of bump rubber.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of suspension buffer block assembly, comprise bump rubber support, bump rubber base and bump rubber, described bump rubber support is provided with bump rubber base, bump rubber cone boss is had bottom described bump rubber, the bump rubber attachment face of described bump rubber support has circular hole, and described bump rubber cone boss is fixed on described bump rubber base through described circular hole.Bump rubber, by the circular hole on bump rubber, is fitted in the cone boss of bump rubber on the bump rubber base of Frame Welding, and this makes bump rubber by the free assembly and disassembly of circular hole, and then to make to press-fit and convenient disassembly, and structure is simple, reduces costs; On the other hand, described bump rubber base and circular hole also can the structures of firm bump rubber assembly, the displacement of restriction bump rubber, thus improve the service life of bump rubber assembly.
Further, the bump rubber attachment face upper punch of described bump rubber base is pressed with one section of flange, and described bump rubber is fixed on described bump rubber base flange by described bump rubber cone boss extruding.This makes to install and dismantle more simple, and the design of described bump rubber cone boss groove simultaneously effectively can reduce bump rubber press-in and extract required power.
Further, the striking face of described bump rubber is designed with spherical boss.This effectively can reduce described bump rubber and clash into the abnormal sound produced, and improves the comfort property of suspension.
Further, described spherical boss circumferentially arranged in arrays.This can make spherical boss can bear impact and the displacement of all directions, and this can reduce the abnormal sound produced when bump rubber is started working effectively, improves the comfort property taken.
Further, described bump rubber cone boss has multiple groove.Bump rubber cone boss is designed with groove, significantly reduces power required when bump rubber press-fits and dismantles, under ensureing the prerequisite dropped in the middle part of described bump rubber working process simultaneously, reduce bump rubber as much as possible and press-fit and power required for dismantling.
Further, the bottom surface of described bump rubber is designed with multiple groups of slots.This can effectively reduce in the course of the work due to when described bump rubber bottom surface and described bump rubber base contacts due to abnormal sound that air movement causes.
Further, described bump rubber is made up of rubber or polyurethane material, and described bump rubber manufacturing process is injection moulding.This can improve the intensity of bump rubber and reduces rigidity by actv., can improve service life of bump rubber by actv., reduce cost of manufacture simultaneously.
Implement a kind of suspension buffer block assembly of the present invention, there is following beneficial effect: what change bump rubber press-fits dismounting mode, structure is simple, cost is low, by the design feature of groove on bump rubber and boss, significantly reduce the abnormal sound produced in bump rubber working process, reduce the initial rigidity of bump rubber, improve the comfort property taken.

Detailed description of the invention
Can understand for the ease of those of ordinary skill in the art and implement the present invention, below in conjunction with figure, embodiments of the present invention is further illustrated.
In automobile torsion beam rear suspension Buffer Unit embodiment 1 of the present invention, its structure as shown in Figure 1,2,3, 4:
A kind of suspension buffer block assembly, comprise bump rubber support 1, bump rubber base 2 and bump rubber 3, described bump rubber support 1 is provided with bump rubber base 2, cone boss 302 is had bottom described bump rubber, described bump rubber is fixed on described bump rubber base by described bump rubber cone boss, described bump rubber support 1 is welded on vehicle frame, described bump rubber base 2 is welded on described bump rubber support 1, described bump rubber 3 is fitted on described bump rubber base 2, a circular hole is had centered by described bump rubber base 2, described bump rubber cone boss 302 press-fits through described circular hole and is fixed on described bump rubber base.Described bump rubber can realize being separated of bump rubber and bump rubber base by circular hole, makes bump rubber easy to loading and unloading.
