Abstract
The invention discloses a hitch buffer unit comprising a front connecting member, a buffer member and a rear connecting member connected in sequence; the buffer member comprises a rubber buffer, an elastic cement buffer and a folded-collapse tube connected in sequence; the elastic cement buffer is connected with the rubber buffer through a hinge member; the folded-collapse tube is fixedly connected with the elastic cement buffer. The hitch buffer unit can well absorb bumping energy, is excellent in buffer performance, can keep buffer force to be stable, and can prevent large impact.
Description
Technical field
The present invention relates to field of track traffic, particularly to a kind of coupler and draft gear.
Background technology
It is said that in general, train occurs the probability collided little, it might even be possible to stop the generation of this type of accident theoretically.But, reality not ensuring that, train car accident absolutely not occurs, particularly with the system of the such bulky complex of Shanghai Underground.And once there is train car accident, it is possible to cause vehicle damage, or even personnel's heavy casualties.Therefore, coupler and draft gear is the important component part of train.Coupler and draft gear, except having cushioning effect during train traction braking, also has the kinetic energy absorption when train clashes into, relaxes impact and the effect of protection passenger.But, the shock-absorbing capacity of existing coupler and draft gear is relatively low, it is impossible to collide the requirement not damaged when meeting train speed 25km/h.
Summary of the invention
The technical problem to be solved in the present invention is the defect that the shock-absorbing capacity in order to overcome prior art to exist is low, it is provided that a kind of coupler and draft gear.
The present invention is to solve above-mentioned technical problem by following technical proposals:
A kind of coupler and draft gear, it include being sequentially connected with one before connection member after connection member, a buffer unit and, its feature is, described buffer unit includes a rubber bumper, an elastic cement buffer and the conquassation pipe being sequentially connected with, described elastic cement buffer is connected with described rubber bumper by an articulated elements, described conquassation pipe is fixing with described elastic cement buffer to be connected, described front connection member is connected with described rubber bumper, and described rear connection member is connected with described conquassation pipe.
It is preferred that described rubber bumper includes that a rubber bumper, described rubber bumper are annular.
It is preferred that described elastic cement buffer includes that a cylinder body and is located at described cylinder body inner carrier, between described piston and described cylinder body, it is provided with an elastic cement.
It is preferred that described front connection member is hook-shaped.
It is preferred that described rear connection member is hook-shaped.
The most progressive effect of the present invention is:
1, under the collision situation of relatively low velocity, rubber bumper and elastic cement buffer act on jointly, make cushion effect be maintained at smoothly in relatively low scope.
2, when impact velocity is higher, elastic cement buffer and conquassation pipe act on jointly, can either effectively absorb bigger collision energy, can be maintained in the range of the crushing force less than conquassation pipe by cushion effect again, effectively utilize buffer stroke.
3, the present invention can make hitch buffer structure absorb collision energy according to the size of impact velocity by different level, keeps cushion effect steady, it is to avoid bigger impact occurs.
4, the present invention can also avoid conquassation pipe to it is frequently necessary to the shortcoming changed.
Accompanying drawing explanation
Fig. 1 is the structural representation of present pre-ferred embodiments.
Detailed description of the invention
Name preferred embodiment, and combine accompanying drawing and become apparent from intactly illustrating the present invention.
As shown in Figure 1, a kind of coupler and draft gear, it includes front connection member 1, buffer unit and the rear connection member 2 being sequentially connected with, buffer unit includes rubber bumper 3, elastic cement buffer 4 and the conquassation pipe 5 being sequentially connected with, elastic cement buffer 4 is connected with rubber bumper 3 by an articulated elements, conquassation pipe 5 is fixing with elastic cement buffer 4 to be connected, and front connection member 1 is connected with rubber bumper 3, and rear connection member 2 is connected with conquassation pipe 5.
Rubber bumper, elastic cement buffer and conquassation pipe are existing common parts, just repeat no more at this.
Rubber bumper can have various version, and in the present embodiment, rubber bumper includes an annular rubber bumper.So, both decreased the weight of rubber bumper, can guarantee that again buffering effect.
Elastic cement buffer can have various version, and in the present embodiment, elastic cement buffer includes that a cylinder body and is located at cylinder body inner carrier, is provided with an elastic cement between piston and cylinder body.By coordinating of piston and elastic cement, preferably realize the effect of buffering.
In said structure, front connection member and rear connection member can be hook-shaped.So, there is advantage easy to connect.
Using the coupler and draft gear of the present invention on train, if train collides when relatively low velocity, rubber bumper and elastic cement buffer can act on jointly, make cushion effect be maintained at smoothly in relatively low scope.
If train collides when speed is higher, elastic cement buffer and conquassation pipe act on jointly, can either effectively absorb bigger collision energy, cushion effect can be maintained in the range of the crushing force less than conquassation pipe again, effectively utilize buffer stroke.
The coupler and draft gear of the present invention can make hitch buffer structure absorb collision energy according to the size of impact velocity by different level, keeps cushion effect steady, it is to avoid bigger impact occurs, avoids conquassation pipe to it is frequently necessary to the shortcoming changed simultaneously.
In describing the invention, it will be appreciated that, term " on ", D score, "front", "rear", "left", "right", " vertically ", " level ", " top ", " end ", " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, it is for only for ease of the description present invention and simplifies description, rather than instruction or hint indication device or element must have specific orientation, with specific azimuth configuration and operation, be therefore not considered as limiting the invention.
Although the foregoing describing the detailed description of the invention of the present invention, it will be appreciated by those of skill in the art that this is merely illustrative of, protection scope of the present invention is defined by the appended claims.These embodiments, on the premise of without departing substantially from the principle of the present invention and essence, can be made various changes or modifications, but these changes and amendment each fall within protection scope of the present invention by those skilled in the art.
