Description

Spherical joint car coupler of railway wagon

Technical field

The utility model relates to a kind of coupling device of rolling stock lorry, especially relates to a kind of spherical joint car coupler of railway wagon.

Background technology

The joint hitch is developed by the U.S. the earliest, is mainly used on the railway transportation heavy-duty freight car.Many vehicle stationary can be connected to one unit car group by the articulated type hitch, can reduce the quantity of bogie truck, energy disperser, brake equipment etc. like this, also can reduce maintenance, reduce the unhook probability, reduce complete vehicle weight, shorten train length, improve the heavy degree of utilization of axle, improve the vibrations performance of car body.

Existing joint hitch comprises the SAC-I type joint hitch of eliminating clearance type joint hitch and the production of U.S. WABTEC company certainly that U.S. ASF company produces.

The keystone configuration of eliminating clearance type joint hitch certainly that U.S. ASF company produces is made up of a plurality of parts such as insertion end, socket end, slave plate, ball, pin bearing slide block, stub, voussoir and ring seats.Any abrasion for accumulation produces can recline to keep seamless connectivity by the voussoir automatic compensation.Vertically after the abrasion, the stroke of voussoir can be recovered by increasing disk gasket.The stroke of voussoir can be seen by inspection door, and assembling for convenience and decomposition allow inspection door to insert ripping bar and lever up wedge.This from eliminating clearance type joint adaptor union because component part is many, when newly making assembling or changing new product more loaded down with trivial details, also need contact surface between lubricated each part; Described from eliminate clearance type joint hitch decompose remove between, must pass inspection door with crow bar and lever up voussoir, during maintenance, need to use model to check the abrasion of each part, difficulty is repaired in part abrasion back.

SAC-I type joint hitch mainly is made up of a buttknuckle, recessed joint and bindiny mechanism etc., the structure decrease of forming than traditional employing two bearings circle parts, be easy to install.But its lubricated form that adopts is single, the material composition complexity, and cost is higher.

Summary of the invention

Problem to be solved in the utility model be exactly provide a kind of compact conformation at above deficiency, number of parts is few, self-lubricating is non-maintaining, no gap, spherical joint car coupler of railway wagon that safety factor is high.Its technical scheme is as follows:

It comprises insertion end and socket end, its gordian technique is that insertion end has the insertion end body, insertion end body one end has the cylindricality through hole, spherical axle is installed in the cylindricality through hole, between spherical axle and cylindricality through-hole wall, the bearing shell with sphere inner chamber is installed, bearing shell has the steel body, and at the bonding self-lubricating of the Internal Spherical Surface of steel body watt lining, self-lubricating watt lining cooperates with the sphere of spherical axle; Socket end has the socket end body, and the socket end body has left side wall, right side wall and diapire, and left side wall, right side wall and diapire constitute spherical inner chamber, and the built-in goal oblique crank Z of spherical inner chamber links together insertion end and socket end.

Advantage compared with prior art of the present utility model and beneficial effect are:

1, the effect of the utility model spherical joint hitch is that two underframe are connected together, and makes the shared bogie truck of two cars.The spherical joint hitch can not only transmit longitudinal force, also can transmit vertical force.Adopt the spherical joint hitch, lorry has been cancelled hitch and energy disperser at the adaptor union place, realizes hanging seamless company of train, can significantly reduce the train longitudinal impulse, optimizes longitudinal dynamic force of train and learns performance, ensures the train safe transportation.

2, because the setting of spherical axle and bearing shell makes the spherical joint hitch realize absolute tight seamless connection, need not adjust the clearance, thereby make compact conformation, and reduce amount of parts.

3, owing to adopt the alloy steel integral body of high abrasion, high strength, self-lubricating composite watt lining or self-lubricating function to make, make spherical hitch need not unnecessary lubricating system, really accomplish non-maintaining, applicating maintenance to railway truck has realistic meaning, reaches 40 years fatigue life or 8,000,000 kilometers.

4, because ball coupling, this joint hitch can rotate suitable wide-angle at vertical direction, several axis directions of horizontal direction, makes vehicle all need not uncoupling at change of wheels with when safeguarding.

5, described utility model makes railway truck reduce weight, shortens length, and cost-cutting reduces the unhook probability, improves safe reliability, makes railway truck improve conveying efficiency.
