The technical solution adopted for the present invention to solve the technical problems is: provide a kind of suspension buffer block assembly, bag
Include buffer stopper support, buffer stopper base and buffer stopper, described buffer stopper support is provided with buffer stopper base, at the bottom of described buffer stopper
There is buffer stopper cone boss in portion, and the buffer stopper installed surface of described buffer stopper support has circular hole, described buffer stopper cone boss
It is fixed on described buffer stopper base through described circular hole.Buffer stopper is by the circular hole on buffer stopper, convex for the taper of buffer stopper
Platform is fitted on the buffer stopper base of Frame Welding, and this makes buffer stopper can pass through the free assembly and disassembly of circular hole, and then makes
Must press-fit and convenient disassembly, simple in construction, reduce cost；On the other hand, described buffer stopper base and circular hole can also consolidate slow
Rush the structure of block assembly, limit the displacement of buffer stopper, thus improve the service life of buffer stopper assembly.
Further, the buffer stopper installed surface of described buffer stopper base being stamped with one section of flange, described buffer stopper passes through
The extruding of described buffer stopper cone boss is fixed on described buffer stopper base flange.This makes to install and dismantle the simplest, with
The design of Shi Suoshu buffer stopper cone boss groove can be effectively reduced buffer stopper press-in and extract required power.
Further, the striking face of described buffer stopper is designed with spherical boss.This can be effectively reduced described buffering
Block clashes into the abnormal sound produced, and improves the comfort property of suspension.
Further, described spherical boss circumferentially array is arranged.This is so that spherical boss can bear each side
To impact and displacement, this can be effectively reduced the abnormal sound produced when buffer stopper is started working, improve the comfort property taken.
Further, described buffer stopper cone boss has multiple groove.It is designed with groove on buffer stopper cone boss,
Significantly reduce power required when buffer stopper press-fits and dismantles, ensure to drop in the middle part of described buffer stopper work process simultaneously
Under premise, reduce buffer stopper as far as possible and press-fit and power required for dismantling.
Further, the bottom surface of described buffer stopper is designed with multiple groups of slots.This can be effectively reduced worked
The abnormal sound caused due to air movement time in journey due to described buffer stopper bottom surface and described buffer stopper base contacts.
Further, described buffer stopper is made up of rubber or polyurethane material, and described buffer stopper manufacturing process is for being injected into
Type.This can effectively improve the intensity of buffer stopper and reduce rigidity, can effectively improve the service life of buffer stopper, simultaneously
Reduce cost of manufacture.
Implement a kind of suspension buffer block assembly of the present invention, have the advantages that the pressure changing buffer stopper
Mode, simple in construction, low cost are unloaded in mounting or dismounting, by groove on buffer stopper and the design feature of boss, significantly reduce buffering
The abnormal sound produced in block work process, reduces buffer stopper and initiates rigidity, improve the comfort property taken.

Detailed description of the invention
For the ease of those of ordinary skill in the art it will be appreciated that and implement the present invention, below in conjunction with figure to the present invention
Embodiment is described further.
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, including buffer stopper support 1, buffer stopper base 2 and buffer stopper 3, described buffering
Being provided with buffer stopper base 2 on block support 1, have cone boss 302 bottom described buffer stopper, described buffer stopper is by described buffering
