Abstract
The utility model discloses an upper connecting board assembly of a shock absorber. The upper connecting board assembly comprises an upper connecting board outer framework and an upper connecting board inner framework, wherein a rubber structure is arranged between the upper connecting board outer framework and the upper connecting board inner framework, and the upper end and the lower end of the rubber structure are respectively provided with a groove-shaped structure. The friction noise can be reduced by reducing the contact area between rubber and a metal plate; and meanwhile, an elastic gasket is additionally arranged between the upper connecting board assembly and a supporting gasket, thus flexible connection can be formed between the upper connecting board assembly and the shock absorber, the friction noise can be further eliminated, abnormal sound caused by an upper connecting board can be removed, and the whole automobile riding comfort can be increased.
Description
Technical field
The utility model relates to the automobile absorber technical field, especially relates to a kind of vibration damper upper junction plate assembly.
Background technique
At present, the upper junction plate noise reduction measure of vibration damper mainly is to design rubber bumps or rubber convex tendon with tapering at the surface of contact of the rubber of upper junction plate and upper junction plate.
Be 201020526956.2 the disclosed a kind of vibration damper upper bracket assembly of Chinese patent such as the patent No., it comprises vulcanization of rubber part, bearing and cover plate, and vulcanization of rubber part is formed by articulated stand, pad and the vulcanization of rubber; Up and down two end faces of vulcanization of rubber part are respectively arranged with the rubber small embossment with tapering, and the side is provided with the rubber convex tendon along circumference.This kind noise-reduction method can only reduce the noise that upper junction plate causes in actual use, but can not abate the noise fully; And Applicable scope has narrow limitation, and at special-shaped upper junction plate and do not having in the upper junction plate of regular planar, this kind noise reduction measure can't use.
The model utility content
Technical problem to be solved in the utility model provides a kind of vibration damper upper junction plate assembly, eliminates the abnormal sound that upper junction plate causes to reach, and promotes the purpose of car load NVH performance.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of vibration damper upper junction plate assembly, comprise the outer skeleton of upper junction plate and upper junction plate inner frame, be provided with rubber structure between the outer skeleton of described upper junction plate and the upper junction plate inner frame, the upper/lower terminal section of described rubber structure is equipped with groove shape structure.
The outer skeleton of described upper junction plate is provided with the bolt that is connected for vehicle body.
Resilient pad between the upper junction plate Support cushion of the lower end surface of described upper junction plate inner frame and vibration damper.
The outer skeleton of described upper junction plate and upper junction plate inner frame are sulfided into an overall structure by rubber structure.
The utility model compared with prior art has the following advantages: upper junction plate assembly rubber surface of contact is provided with groove shape structure, dwindles the area of contact between rubber and the sheet metal, reduces friction noise; Simultaneously between upper junction plate assembly and Support cushion, set up a resilient pad, make to form between upper junction plate assembly and the vibration damper to flexibly connect further elimination friction noise, eliminate the abnormal sound that upper junction plate causes, promote the riding comfort of car load.
Description of drawings
The below makes brief description to the expressed content of each width of cloth accompanying drawing of this specification and the mark among the figure:
Fig. 1 is the utility model upper junction plate assembly organigram.
Among the figure: 1. the outer skeleton of upper junction plate, 2. rubber structure, 3. resilient pad, 4. upper junction plate inner frame, 5. piston lever of reducer, 6. upper junction plate Support cushion, 7. bolt, 8. pad, 9. nut.
Embodiment
The below contrasts accompanying drawing, by the description to embodiment, embodiment of the present utility model is described in further detail.
As shown in Figure 1, a kind of vibration damper upper junction plate assembly is used for being connected between vehicle body and the vibration damper, and it comprises the outer skeleton 1 of upper junction plate and upper junction plate inner frame 4, upper junction plate inner frame 4 centers are provided with via hole, and piston lever of reducer 5 passes by nut 9 fixing from via hole; Be provided with rubber structure 2 between the outer skeleton 1 of upper junction plate and the upper junction plate inner frame 4, and by rubber structure 2 the outer skeleton 1 of upper junction plate be sulfided into an overall structure with upper junction plate inner frame 4, between nut 9 and rubber structure 2, be provided with pad 8; Upper/lower terminal section at rubber structure is equipped with groove shape structure, reduced the area of contact between the pad of rubber structure and metal, reduced the friction sound of rubber structure and pad, existence with time slot shape structure, also be conducive to the be squeezed discharge of space-time intracavity gas of rubber, reduce exhaust sound.
Wherein, the outer skeleton 1 of upper junction plate is provided with for 7, three bolts of three bolts that are connected with vehicle body on the identical graduation circle.
The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that design of the present utility model and technological scheme carry out; or without improving design of the present utility model and technological scheme are directly applied to other occasion, all within protection domain of the present utility model.
