Abstract
The utility model relates to a shock damper for a towing hook of a car. A sliding sleeve, a flange, an annular rubber pad, a flange and a sliding sleeve are installed on the towing hook in sequence, wherein, both end faces of the annular rubber pad are respectively provided with an annular groove, and the end faces of the two flanges, which contact the annular rubber pad, are respectively provided with annular tenons which are compensated with the annular grooves. Disengagement stop hooks are respectively arranged between the end faces of the annular rubber pad and the end faces of the flanges. The shock damper for the towing hook of a car of the utility model can satisfy the use of cars with different carrying capacities and has the advantages of unique structure, high safety factor, good damping effect, long service life, high safety, easy maintenance, low price, strong practicability, wide range of application, etc.
Description
The utility model belongs to vehicular spare parts, is specifically related to a kind of Automotive Drawbar bumper.
In the prior art, Automotive Drawbar generally all adopts the steel spring.Because the safety factor of steel spring is on the low side, make the steel spring when work, be subjected to the effect of shearing force, fatigue damage easily makes spring failure.
The purpose of this utility model solves above existing in prior technology problem with regard to being, provides that a kind of structure uniqueness, safety factor height, damping are good, long service life, safe and reliable Automotive Drawbar bumper.
The technical solution of the utility model is to realize like this.The Automotive Drawbar bumper comprises towing hook, flange, sliding sleeve, annular rubber cushion etc., and sliding sleeve, flange, annular rubber cushion, flange and sliding sleeve are installed on the towing hook successively; Be respectively equipped with circular groove on two end faces of annular rubber cushion, be respectively equipped with on two flanges and the contacted end face of annular rubber cushion with annular rubber cushion on the annular tenon that compensates mutually of set circular groove, between the end face of annular rubber cushion and the end face of flange locking hook is housed.
Described annular rubber cushion can be an integral body, also can be compound type annular rubber cushion, and compound type annular rubber cushion is by two annular rubber cushions and be contained in two damping fins between the annular rubber cushion and form.
Described compound type annular rubber cushion also can be made up of two annular rubber cushions, damping fin and annular nylon support, between two annular rubber cushions damping fin is housed, and annular nylon carrying sleeve is contained on the towing hook, and is fixedly connected with damping fin.
Described flange and sliding sleeve are made by metallic material.
Below in conjunction with accompanying drawing the utility model is further described.
Structural representation when Fig. 1 is an integral body for the utility model annular rubber cushion;
Structural representation when Fig. 2 adopts compound type annular rubber cushion for the utility model;
Another structural representation when Fig. 3 adopts compound type annular rubber cushion for the utility model.
Referring to shown in Figure 1, the Automotive Drawbar bumper is made up of towing hook 7, flange 3,5, magnesium iron sliding sleeve 2,6, annular rubber cushion 4 etc.Magnesium iron sliding sleeve 2, flange 3, annular rubber cushion 4, flange 5, magnesium iron sliding sleeve 6 are installed on the towing hook 7 successively, and annular rubber cushion 4 is an integral body, is respectively equipped with circular groove on two end face, and certain giving under the tight power, annular rubber cushion 4 is born pressure jointly with pressurized air.Flange 3,5 is made by cast iron or cast steel material, be respectively equipped with annular tenon on flange 3,5 and the annular rubber cushion 4 contacted end faces, set circular groove compensates mutually on annular tenon and the annular rubber cushion 4, for preventing to break away from the flange positioning grooves, between the end face of the end face of annular rubber cushion 4 and flange 3,5, locking hook 1 is housed because of inertia causes annular rubber cushion 4.
This scheme rubber cushion good springiness, load-carrying capacity is big, and the return performance is good, and bearing capacity can be above 20 tons.
Structural representation when Fig. 2 adopts compound type annular rubber cushion for the utility model.This compound type annular rubber cushion is made up of annular rubber cushion 8,9, damping fin 10, and damping fin 10 is contained between the annular rubber cushion 8,9.
Another structural representation when Fig. 3 adopts compound type annular rubber cushion for the utility model.This compound type annular rubber cushion is made up of annular rubber cushion 11,12, damping fin 13 and annular nylon support 14.For overcoming the problem of the excessive early stage defatigation of somatotype place local deformation; between annular rubber cushion 11,12, set up steel damping fin 13; be protection steel damping fin 13; be provided with annular nylon support 14; annular nylon support 14 is sleeved on the towing hook 7, and is fixedly connected by rivet and steel damping fin 13.
More than the automobile absorber of several different structures, can satisfy the automotive use of different bearer ability, be several times to tens times of former steel spring service life, and have simple in structure, unique, the safety factor height, damping is good, safe and reliable, easy to maintenance, advantage such as cheap is a kind of Automotive Drawbar bumper practical, applied widely.
