Abstract
An automobile buffer shock-proof device can let spring be tightly inserted into working grooves to reinforce the elastic force of the helical spring by annular working grooves on two upper and lower faces of the annular rubber. The circumference of the annular rubber is equispaced and can respond sharply to the pressure variation acted on it, which has buffer action on the spring when the automobile turns or is on an uneven road. The utility model is provided with an extra reinforcement layer on the opening end, which increases service life greatly. The utility model can be produced as serial products for various vehicles.
Description
Technical field:
The utility model relates to automotive field, belongs to a kind of shock-absorbing protecting device of motor spring.
Background technique:
At present; automobile damping spring can lose efficacy in use for some time; must in time change; a kind of automobile spiral spring buffer is arranged; adopt ring rubber groove protection motor spring; can play the bumper and absorbing shock effect; but have two elongated slot through holes on this buffer; be positioned at ring-shaped rubber opening both sides, make full annular rubber discontinuity can not guarantee the stable of support force; reduced the working life of buffer again; especially the most fragile in the opening slot end, owing to there are these defectives, make the sort buffer device be difficult to promote the use of.
Summary of the invention:
The purpose of this utility model is to overcome the deficiency that above-mentioned prior art exists, thereby a kind of automatic buffer damping device is provided, and stressed even, wear-resisting, improve working life greatly.
The purpose of this utility model realizes in the following way.
This damping device main body is a ring-shaped rubber, have axial opening 4, the upper and lower end face of ring-shaped rubber respectively has the last processing groove 2 and the following processing groove 3 of annular, processing groove cross section opening is little, rounded cross section in the groove also has the through hole 5 that connects inside and outside wall in the ring-shaped rubber side, wherein: perforation 5 is a circular hole also, evenly distribute along ring-shaped rubber 1 circumference, have reinforced layer 6 on opening 4 surfaces.
The material of reinforced layer 6 can be the rubber of good springiness, is connected with the end face heat seal of opening 4, on the end face about also can being embedded between the processing groove.
The material of reinforced layer 6 can be the nylon-type rigid material, divides on two sections end faces that are embedded in opening groove about in the of 4.
The utlity model has following advantage:
The processing groove that the utility model forms by the upper and lower surface at circular buffer, helical spring is closely inserted, allow helical spring elastic force be strengthened, equally distributed circular hole makes stressed even, can make the reaction of quick tax to effect variation in pressure thereon, when automobile turning, can play buffer function to the lateral pressure that acts on the helical spring, and when brake, improve the stability of spring, on irregular road, spring is played buffer function simultaneously, reinforced layer can make the utility model open end not fragile, thereby has improved working life of the present utility model.
Description of drawings:
Fig. 1 is an outline drawing of the present utility model.
Fig. 2 is a main sectional view of the present utility model.
Fig. 3 is the utility model user mode figure.
In Fig. 1: 1. ring-shaped rubber; 2. go up processing groove; 3. descend processing groove; 4. opening, 5. through hole, 6. reinforced layer.
In Fig. 3,7. helical spring
Embodiment:
See that Fig. 1 bumper material is a rubber product, form by cutting, through hole is circular, quantity is 4, is distributed on the ring-shaped rubber circumference, and concrete the use seen Fig. 3, on the helical spring above the wheel 7, use the utility model, by the processing groove 2 and 3 of buffer upper and lower surface, spring is inserted also tightly encase, four wheels preferably all use.The utility model can be designed to series product according to the model of spring, and same model can be general.Fig. 2 has shown the sectional shape of processing groove.
Fig. 1 represents embodiment of the utility model, and opening 4 end faces have reinforced layer 6 by heat seal, and reinforced layer 6 can be softer rubber; opening 4 is shielded; can select hard material yet, be embedded in the end face of processing groove up and down respectively, present embodiment does not give demonstration.
