Abstract
The utility model provides a semi-permanent coupler of a rail vehicle, which comprises a hollow rod body, a front part connecting end and a tail part connecting end. The front part connecting end andthe tail part connecting end are respectively arranged on the two ends of the rod body, wherein the front part connecting end is provided with a connecting surface which is provided with at least twoconnecting holes, the tail part connecting end is provided with a connecting pin hole which is connected with a buffer. The utility model has the following advantages that: the connecting surface of the semi-permanent coupler is provided with the connecting hole, and the bolt is used for transmission of the traction force, thereby the capability of the coupler for transmission of the traction force is greatly improved; the coupler can directly replace the existing coupler connected in the sealing way and be used in the train of the existing motor train unit without any transformation; and thecoupler has an integrated structure, the performance thereof is stable, and the production and maintenance costs are low.
Description
Technical field
The utility model relates to a kind of vehicle shock absorber, and is especially a kind of for satisfying traveling comfort and operation security requirement that the passenger takes, reducing the semi-permanent car coupler of train cost of manufacture, belongs to the guideway vehicle technical field.
Background technology
Along with the fast development of China Express Railway and urban track traffic, the passenger has proposed more and more higher requirement to the safety and the comfort level of train operation.According to the result of rolling stock kinetic theory and simulation calculation, dwindle the longitudinal impulse that gap between the hitch can reduce vehicle effectively, improve the dynamic performance of train.Therefore extensively adopt novel hitch to replace common hitch to reduce the inexorable trend that coupler slack is the guideway vehicle development.The gap is little though tight lock coupler has, technology integrated level height, advantage such as easy to operate, but there is the high deficiency of complex structure, manufacturing and maintenance cost, therefore not all to adopt tight lock coupler on motor train unit, subway and light rail vehicle, junior unit inside in the fixedly marshalling of vehicle, usually adopt semi-permanent car coupler to replace tight lock coupler, to save cost.Two semi-permanent car couplers that connect together fasten as one, and the gap is zero, does not have mutual motion, use therefore that performance is better, wearing and tearing are littler, and the vehicle comfort level is better.
As shown in Figure 1, by being located at annular boss 101 and two the semi-ring connector 14 transmitting tractive power up and down on the relative joint face 103 on the hitch, the outside that connector 14 is stuck in annular boss 101 is used to connect two semi-permanent car couplers between the present existing semi-permanent car coupler vehicle.Because the height of annular boss generally has only about 9mm, the tractive force of transmission is less, generally is used to be no more than the vehicle of 1000kN, therefore is mainly used in subway and light rail vehicle; In addition, semi-permanent car coupler also need be divided into several major parts to be processed respectively, comprises body, the afterbody coupling end of hollow, anterior coupling end, then with these several parts by being threaded togather.This semi-permanent car coupler structure is comparatively complicated, and safety is not high, makes simultaneously and the maintenance cost height.
The utility model content
The purpose of this utility model is to solve above-mentioned technical matters, a kind of used for rail vehicle semi-permanent car coupler is provided, can bear bigger tractive force, can be used on the high speed train, and can directly replace existing tight lock coupler and have motor train unit train now, need not to reequip with existing energy disperser supporting being used for.
The purpose of this utility model is achieved through the following technical solutions:
A kind of used for rail vehicle semi-permanent car coupler comprises the body of rod of hollow and lays respectively at the anterior coupling end and the afterbody coupling end at body of rod two ends that described anterior coupling end has a joint face, and described joint face is provided with at least two connecting bores.Described afterbody coupling end is provided with and is used for the pin-and-hole that is connected that links to each other with energy disperser.
Further, described joint face is perpendicular to the axis of described hollow lever.
Again further, vertically be provided with convex cone and concave cone on the described joint face, described convex cone and concave cone are projected as two circles that area equates on described joint face.
Further, described joint face is provided with at least one air AUI.
The beneficial effects of the utility model are mainly reflected in:
1) described semi-permanent car coupler joint face has connecting bore, and by bolt transmitting tractive power, can improve the ability of hitch transmitting tractive power greatly;
2) can directly replace existing tight lock coupler, be used for existing motor train unit train and need not to transform;
3) hitch is an integral body, and performance is more stable, and making and maintenance cost are lower.

The specific embodiment
The utility model has disclosed a kind of used for rail vehicle semi-permanent car coupler, is used for the connection between the guideway vehicle.As Fig. 2, Fig. 3, shown in Figure 4, described used for rail vehicle semi-permanent car coupler comprises the body of rod 37, anterior coupling end 38 and the afterbody coupling end 39 of hollow.Described anterior coupling end 38 has a joint face 803, and described joint face 803 is perpendicular to the axis of described hollow lever 37.
Vertically be provided with convex cone 801 and concave cone 802 on the described joint face 803, described convex cone 801 and concave cone 802 are projected as two circles that area equates on described joint face.Described convex cone 801 and concave cone 802 can match mutually, promptly the convex cone 801 on semi-permanent car coupler can be inserted in the concave cone 802 on another semi-permanent car coupler, and the convex cone 801 on another semi-permanent car coupler can be inserted in the concave cone 802 on this semi-permanent car coupler.
Described joint face 803 is provided with at least two connecting bores 804, and this preferred embodiment is provided with four connecting bores 804 on four jiaos of the anterior coupling end 38 that roughly is square.On described joint face 803, can have one or more than one air AUI 40 according to the needs of train.
Described afterbody coupling end 39 has the pin-and-hole 901 of connection, is connected with energy disperser by pin.Described connection pin-and-hole 901 runs through the body of rod 37 of described hollow.
When two hitches are even hung, as shown in Figure 5, convex cone 801 inserts respectively in the hole of cooresponding concave cone 802, so just limited horizontal and vertical the moving of hitch, for the position has been reserved in the alignment of hitch connecting bore 804, behind two hook joint faces, 803 closed contacts, two hitches are even be suspended to the position, utilize bolt 41 and nut 42 that two hitches are linked together, reach the purpose of transmitting tractive power.As required, can on joint face 803, design two or more connecting bore.When between the vehicle during transmitting tractive power, the front end vehicle is delivered to the hitch of front end with tractive force, is delivered to the hitch of back then by screw bolt and nut, is delivered to back vehicle at last, reaches the purpose of traction; If when transmitting compressive force between the vehicle, the back vehicle is delivered to the hitch of back with compressive force, by joint face compressive force is delivered to the fwd hitch then, is delivered to the fwd vehicle at last, and this moment, screw bolt and nut did not bear compressive force.
Semi-permanent car coupler of the present utility model can improve the ability that hitch bears tractive force by the material that changes hitch, the quantity of joint face connecting bore, satisfies the needs of different trains.
The utility model also has multiple implementation.All employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the claimed scope of the utility model.
