Abstract

The utility model discloses a bidirectional buffering traction device used for the traction of an automobile over a trailer. The device at least comprises a traction device body, wherein the traction device body comprises a base provided with screw holes and traction rings fixedly arranged on the base, and is fixedly arranged on an environmental part of the automobile by bolts penetrating through the screw holes; a front buffering spacer is arranged between the base and the environmental part; clamping grooves are arranged at entering ends of the screw holes; and buffering gaskets are arranged in the clamping grooves. The bidirectional buffering traction device has a simple structure, and a bidirectional buffering function can be realized in a limited mounting space only by adding the forward buffering spacer and the backward buffering gaskets in an internal structure of the current buffering device, and extra buffering devices do not need to be added.

Description

The bidirectional buffering draw gear
Technical field
The utility model relates to draw gear, and specifically a kind of being installed in is used to the bidirectional buffering draw gear that draws on the automobile.
Background technology
Present cross-country car needs drawbar trailer usually, because the quality of trailer is bigger, when main car (cross-country car) starts or brakes, is easy to main car is brought impact, and very the person causes hurt to main car.Therefore, the draw gear that needs forward and backward bidirectional buffering is to reduce the impact to main car.But existing draw gear with bidirectional buffering function, general required installing space is big, is fit to be installed on the sufficient vehicle in space, for the not enough vehicle of installing space, not only increases the burden of main car, and influences the outward appearance of main car.
Summary of the invention
The utility model purpose is to overcome the deficiency of above-mentioned prior art and a kind of bidirectional buffering draw gear is provided, and under the situation that does not increase the draw gear volume, realizes the forward and backward bidirectional buffering to vehicle.
Realize that the technical scheme that the utility model purpose adopts is: a kind of bidirectional buffering draw gear; At least comprise the draw gear body; Said draw gear body comprises the base that has screw and is fixed on the eye hitch on the base that the draw gear body is provided with preceding buffering spacer by on the environment part that is bolted to automobile that passes screw between said base and the environment part; The upstream end of said screw is provided with draw-in groove, is provided with buffer gasket in the said draw-in groove.
Further, said buffer gasket comprises spacer layer and buffering rubber layer, and said yielding rubber layer snaps in the draw-in groove.
Further, the aperture of said yielding rubber layer is slightly less than the aperture of spacer layer.
The utility model is provided with preceding buffering spacer between the environment part of traditional draw gear body and automobile, the impulsive force when being used to cushion main car brake between base and the environment part.Impulsive force when buffer gasket is used to cushion main car and starts between base and the bolt.
The utility model is simple in structure, only need between the inner structure of existing shock absorber, to increase forward directed buffering spacer and back to buffer gasket, need not to increase extra shock absorber, can guarantee in limited installing space, realize the function of bidirectional buffering.
Description of drawings
Fig. 1 is the structural representation of the utility model bidirectional buffering draw gear.
Fig. 2 is a traction main body structure scheme drawing among Fig. 1.
Fig. 3 is the birds-eye view of buffer gasket among Fig. 1.
Fig. 4 is that the E-E of Fig. 3 is to cutaway view.
The specific embodiment
As depicted in figs. 1 and 2; The bidirectional buffering draw gear comprises draw gear body 1; Draw gear body 1 comprises the base 11 that has screw 13 and is fixed on the eye hitch 12 on the base 11; Draw gear body 1 is fixed on by the bolt that passes screw 2 on the environment part 4 of automobile, and the environment part 4 in the present embodiment is the rear bumper of automobile.Wherein, buffering spacer 6 before being provided with between base 11 and the environment part 4, the upstream end of screw 13 is provided with draw-in groove 8, is provided with buffer gasket 5 in the draw-in groove 8.
Like Fig. 3 and shown in Figure 4; Buffer gasket 5 comprises spacer layer 51 and buffering rubber layer 52; The aperture of spacer layer 51 is slightly less than the aperture of yielding rubber layer 52, and yielding rubber layer 52 snaps in the draw-in groove 8, because the aperture of spacer layer 51 is little; Therefore can yielding rubber layer 52 be stuck in the draw-in groove 8 securely, improve the steadiness of buffer gasket 5.Bolt 2 passes buffer gasket 5 and from screw, passes environment part 4, after through nut bolt being tightened draw gear body 1, preceding buffering spacer 6 and environment part 4 securely is connected again.
Because preceding buffering spacer 6 is between the base 11 and environment part 4 of draw gear body 1, when main car braked, the impulsive force between preceding buffering spacer 6 buffering bases 11 and the environment part 4 cushioned before plaing a part.When main car started, the base 11 of buffer gasket 5 buffering draw gear bodies 1 and the impulsive force between the bolt 2 played the back buffering.

Claims (3)

1. bidirectional buffering draw gear; At least comprise the draw gear body; Said draw gear body comprises the base that has screw and is fixed on the eye hitch on the base that the draw gear body is characterized in that: be provided with preceding buffering spacer between said base and the environment part by on the environment part that is bolted to automobile that passes screw; The upstream end of said screw is provided with draw-in groove, is provided with buffer gasket in the said draw-in groove.
2. bidirectional buffering draw gear according to claim 1 is characterized in that: said buffer gasket comprises spacer layer and buffering rubber layer, and said yielding rubber layer snaps in the draw-in groove.
