A kind of spindle bushing
Technical field
A kind of auto parts and components are the utility model is related to, more particularly, to a kind of spindle bushing.
Background technology
In multi-connecting-rod separated suspension system, knuckle bushing is one of important component therein, is connection automobile
" joint " of knuckle and vehicle frame.The performance of suspension directly influences the vehicles such as the control stability of vehicle, riding comfort
Energy.And rubber bushing characteristic has vital effect to suspension system, seem more particularly with the vehicle run at high speed
It is important.The quality of its performance is by the NVH effects for directly influencing automobile chassis, the handling of vehicle or even rides and drives
The comfortableness of personnel.
With the development of auto industry, also more and more higher is more and more finer for requirement of the people to automobile, and people increasingly note
Impression in weight driving procedure.Due to vehicle steering and jolt, the requirement to rubber bushing is also diversified.Knuckle is needed to serve as a contrast
Set can provide different rigidity properties in different directions, and vehicle NVH directions can have relatively low rigidity, play damping, buffering
Effect.
Following defect be present in traditional knuckle bushing;1. traditional knuckle bushing uses integral rubber structure, nothing
Method meets the rigidity requirement of different directions on vehicle.2. original bushing does not have spacing anti-dropout to design, exist under limiting condition
Come off risk.3. original bushing does not assemble anti-skidding design, there is the problem of sliding in automobile during exercise.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of spindle bushing, realizes in different directions energy
The requirement of two greater stiffness difference is provided, solves the existing problem and in vehicle traveling process of coming off under limiting condition
Sliding problem.
Technical scheme is used by the utility model solves above-mentioned technical problem:A kind of spindle bushing, including
Inner frame, outer skeleton and rubber parts, the middle skeleton of two fan loop configuration is additionally provided between described inner frame, outer skeleton,
Two middle skeletons are symmetricly set on the both sides of inner frame, described rubber parts be filled with gap between inner frame and middle skeleton,
And the gap between middle skeleton and outer skeleton, filled without rubber parts between two middle skeletons, one end of described outer skeleton is set
The flange being bent outwardly is equipped with, upper surface, the lower surface of described inner frame are provided with multiple equally distributed anti-slop serrations.
The further preferred scheme of the utility model:Described inner frame is cylindrical-shaped structure, described anti-slop serrations along
Inner frame is radially arranged.
The further preferred scheme of the utility model:The both sides of the flange of described outer skeleton are cut into planar structure.
The further preferred scheme of the utility model:Whole middle skeleton is wrapped in interior by described rubber parts.
The further preferred scheme of the utility model:The height of described inner frame is more than the height of middle skeleton, described
The height of middle skeleton is more than the height of outer skeleton.
Compared with prior art, the utility model has the advantage of two fan annulars are provided between inner frame, outer skeleton
The middle skeleton of structure, two middle skeletons are symmetricly set on the both sides of inner frame, and rubber parts is filled between inner frame and middle skeleton
Gap and middle skeleton and outer skeleton between gap, filled without rubber parts between two middle skeletons.In being moved through for automobile
Cheng Zhongneng reduces the noise and vibration that vehicle body is delivered to by road surface, relative to the unicity of conventional bushing radial rigidity, the bushing
It can meet that the different directions in radial direction provide different rigidity properties, vehicle NVH directions can have relatively low rigidity, play damping
The effect of buffering, increase comfortableness, the handling direction of vehicle can provide higher rigidity, there is less relative displacement, increase
What is turned to is handling.Flange position limiting structure is added on outer skeleton, the spacing knot of flange is added in the outer skeleton upper end of bushing
Structure, the structure primarily serve spacing effect, strengthen fatigue life of the bushing in the case of big displacement is travelled, solve bushing
The risk to come off.Equally distributed anti-slop serrations are designed with bushing inner frame upper and lower end face, prevent the slip in complex working condition
Caused by security problems.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional view of the present utility model.
Embodiment
Below in conjunction with the accompanying drawings, the utility model is described in detail.
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining this
Utility model, it is not used to limit the utility model.
As shown in Figure 1 to Figure 2:A kind of spindle bushing, including inner frame 1, outer skeleton 2 and rubber parts 3, inner frame
1st, the middle skeleton 4 of two fan loop configuration is additionally provided between outer skeleton 2, two middle skeletons 4 are symmetricly set on the two of inner frame 1
Side, rubber parts 3 are filled with the gap between the gap between inner frame 1 and middle skeleton 4 and middle skeleton 4 and outer skeleton 2, and two
Filled between individual middle skeleton 4 without rubber parts 3, one end of outer skeleton 2 is provided with the flange 5 being bent outwardly, the upper end of inner frame 1
Face, lower surface are provided with multiple equally distributed anti-slop serrations 6.
Inner frame 1 is cylindrical-shaped structure, and anti-slop serrations 6 are radially arranged along inner frame 1.Prevent the cunning in complex working condition
Safety problem caused by dynamic.
The both sides of the flange 5 of outer skeleton 2 are cut into planar structure.Facilitate it is of the present utility model installation with it is spacing.
Whole middle skeleton 4 is wrapped in interior by rubber parts 3.Play a part of damping, buffering, meet the comfortableness driven.
The height of inner frame 1 is more than the height of middle skeleton 4, and the height of middle skeleton 4 is more than the height of outer skeleton 2.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
