Description
Technical field
The present invention relates to auto parts machinery and manufacture technical field, a kind of buffer stopper for rear overhang rack.
Background technology
Automobile in motion, causes the suspension spring impact to vehicle body to alleviate wheel hop, can be under vehicle body
The buffer stopper of rubber is installed in portion, to play buffering and spacing effect, typically installs and uses rubber integrally formed at rear suspension
Buffer stopper, in order to clash into the boss of flexible member.Existing a kind of rear suspension buffer stopper as depicted in figs. 1 and 2, this rear overhang
Frame buffer stopper includes a fairlead 1-3 being provided with centre bore, and fairlead 1-3 is provided with flange part 1-4 in centre bore outer rim；Leading
Being provided with buffer stopper in set 1-3, this buffer stopper includes the cylinder 1-2 being contained in fairlead 1-3 and stretches out fairlead 1-3 center
The frustum 1-1 in hole, the bottom surface of frustum 1-1 abuts against with the end face of centre bore flange part 1-4.This rear suspension buffer stopper is using
During there are the following problems: owing to fairlead 1-3 is sheet metal component, the flange part 1-4 of fairlead 1-3 centre bore is high when flange
There is certain tolerance in degree, therefore, rear suspension buffer stopper after completion of installation, cylinder 1-2 end face and fairlead 1-3 inner chamber top
Exist between face and between gap, and cylinder 1-2 outer wall and fairlead 1-3 inwall, there is gap, thus cause buffer stopper to exist
Occur during traveling loosening, be even hit and produce abnormal sound.
Summary of the invention
It is an object of the invention to provide a kind of rear suspension buffer stopper, it can solve existing buffer stopper and the most easily produce
The raw problem loosened with abnormal sound.
In order to solve the problems referred to above, the technical solution used in the present invention is: this rear suspension buffer stopper, is provided with including one
The fairlead of centre bore, described guiding is placed on centre bore outer rim and is provided with flange part；Buffer stopper it is provided with in described fairlead, described
Buffer stopper includes the cylinder being contained in described fairlead and stretches out the frustum of described fairlead centre bore, the bottom surface of described frustum
Abutting against with the end face of described flange part, the described cylinder end face in nearly described frustum side is provided with multiple pellet shapes projection, institute
State cylinder and be provided with many wedge shape reinforcements in its cylindrical body outer wall.
In technique scheme, more specifically technical scheme is it may also is that described wedge shape reinforcement is in described frustum side
Highly less than the height of described cylinder bottom side.
Further, the height of described pellet shapes projection is 0.7 millimeter～0.9 millimeter.
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that
1, buffer stopper is after snapping in fairlead, and the deformation of cylinder dependence pellet shapes salient point provides certain pretightning force, makes cylinder
Body end face is tightly fitted on fairlead inner chamber end face, eliminates impact abnormal sound.
2, many wedge shape reinforcements on cylindrical body outer wall, it is possible to reduce cylindrical body outer wall and the gap of fairlead inwall,
The radial direction reducing buffer stopper rocks probability, Improving The Quality of Products.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing rear suspension buffer stopper；
Fig. 2 is the structural representation of existing buffer stopper；
Fig. 3 is the structural representation of the embodiment of the present invention；
Fig. 4 is the structural representation of embodiment of the present invention buffer stopper.
Detailed description of the invention
The invention will be further described for embodiment below in conjunction with the accompanying drawings:
Embodiment 1:
Rear suspension buffer stopper as shown in Figure 3 and Figure 4, including a fairlead 3 being provided with centre bore, fairlead 3 is at centre bore
Outer rim is provided with flange part 4；Being provided with buffer stopper in fairlead 3, buffer stopper includes the cylinder 2 being contained in fairlead 3 and stretches out
The frustum 1 of fairlead 3 centre bore, the bottom surface of frustum 1 abuts against with the end face of flange part 4, and cylinder 2 is in the top of nearly frustum 1 side
Face is provided with six pellet shapes projections 5, and the height h of pellet shapes projection 5 is 0.8 millimeter；Cylinder 2 is uniformly provided with four on its external wall
Root wedge shape reinforcement 6, the wedge shape reinforcement 6 height in frustum 1 side is less than the height of cylinder 2 bottom side.
Embodiment 2:
The cylinder 2 end face in nearly frustum 1 side is provided with seven pellet shapes projections 5, and the height of pellet shapes projection 5 is 0.7 millimeter, circle
Cylinder 2 is uniformly provided with five wedge shape reinforcements 6 on its external wall, and remaining feature is same as in Example 1.
Embodiment 3:
The cylinder 2 end face in nearly frustum 1 side is provided with eight pellet shapes projections 5, and the height of pellet shapes projection 5 is 0.9 millimeter, circle
Cylinder 2 is uniformly provided with six roots of sensation wedge shape reinforcement 6 on its external wall, and remaining feature is same as in Example 1.
Buffer stopper is after snapping in fairlead 3, and cylinder 2 relies on the deformation of pellet shapes salient point 5 to provide certain pretightning force, makes
Cylinder 2 end face is tightly fitted on fairlead 3 inner chamber end face, eliminates impact abnormal sound；Many wedge shapes on cylinder 2 outer wall add
Strong muscle 6, it is possible to reduce cylinder 2 outer wall and the gap of fairlead 3 inwall, the radial direction reducing buffer stopper is rocked probability, is promoted and produce
Quality.
