The coupler of the device adopts the CA-3 coupler which is manufactured according to the national standard of the commonwealth of the independent states, the coupler is applied to the effective connection of two trucks and the effective connection of a locomotive and a truck, and requirements on the generality and interchangeability of the coupler buffering device of a wagon of the commonwealth of the independent states can be met.

Description

A kind of coupler and draft gear

Technical field

The utility model relates to draw gear and the shock absorber technical field that is specially adapted for rolling stock, relates in particular to a kind of coupler and draft gear.

Background technology

Coupler and draft gear is one of most important parts of rolling stock, and it is mainly dimerous by hitch and energy disperser.Wherein, hitch is used for realizing that the company between rolling stock hangs, transmitting tractive power, impulsive force, and make and keep certain distance between vehicle; Wherein, energy disperser be used for relaxing vehicle in operational process due to the variation of the locomotive tractive effort or when starting, braking and the shunting service vehicle mutually collide longitudinal impact and the vibration that causes, so that the shock and vibration between the dissipation vehicle, thereby alleviate destructive effect to vehicle structure and lade.

At present, domestic railway freight-car coupler shock absorber selects type and spec also to be not quite similar due to the difference of load-carrying, but correlation technique is ripe, and promulgates with the form of standard, obtains on railway truck at home using in batches.Because member country of the Commonwealth of Independent States's railway freight-car coupler shock absorber is different from China accepted standard, interconnection technique is also different; So can not satisfying the existing railway truck of member country of the Commonwealth of Independent States, the interconnection technique of China railways freight car coupler shock absorber uses and exchanges requirement.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of coupler and draft gear, and described device can satisfy the railway truck of member country of the Commonwealth of Independent States and requirement is hung by the company of lorry, lorry and locomotive, and has general characteristics.

For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of coupler and draft gear, it is characterized in that comprising CA-3 type hitch, draft key, hitch slave plate and hook tail frame, be connected by draft key is rotating between described CA-3 type hitch and hook tail frame, described hitch slave plate is between the end and hook tail frame of described CA-3 type hitch.

Preferably: described device also comprise the recovery joist that is positioned at CA-3 type hitch downside with is connected end with restore the joist hook and be connected the hook holder boatswain chair that the other end is connected with the compartment.

Preferably: described device also comprises the hook tail frame supporting plate that is positioned at described hook tail frame downside and captives joint with the compartment.

Preferably: described device also comprises the stay bearing plate that an end is connected with CA-3 type hitch by iron chains.

The beneficial effect that adopts technique scheme to produce is: the hitch of described device adopts CA-3 type hitch, CA-3 type hitch adopts member country of the Commonwealth of Independent States's standard manufacture, be applied between lorry and lorry, the effective connection between locomotive and lorry, can satisfy the General Requirement of member country of the Commonwealth of Independent States's railway freight-car coupler shock absorber and exchange requirement.Under the combined action of hook holder boatswain chair and recovery joist, can control the relative height of draw gear head, hook tail frame supporting plate can change the relative height of hook tail frame, controls the height of draw gear tail, and is highly adjustable, easy to use.The main accessory that described device adopts all can satisfy the operating needs of low-temperature impact, has satisfied simultaneously commonality, the interchangeability of accessory and has been connected with existing the effective of vehicle of member country of the Commonwealth of Independent States.
