Abstract
The utility model discloses a plane bar system drawbar apparatus which comprises two drawbars, two radius bar assemblies and a connecting rod. The middle end of the radius bar assembly is connected with a bogie framework side beam through a radius bar pin. The inner end of the radius bar assembly is connected with the connecting rod through a connecting rod pin. The inner end of the drawbar is connected with the outer end of the radius bar assembly through a rubber ball joint. The outer end of the drawbar is connected with a frame side beam through the rubber ball joint. The rubber ball joint comprises a ball body, a rubber layer which is coated on the outside surface of the ball body and a metal ring which is coated on the outside surface of the rubber layer. Two metal gaskets are also arranged between the rubber layer and the metal ring. The plane bar system drawbar apparatus can transmit traction and braking force better, thus the running quality of the locomotive is improved.
Description
Technical field
The utility model relates to a kind of draw bar device, particularly a kind of plane leverage draw bar device.
Background technology
The draw bar device of locomotive has multiple version, and wherein plane leverage draw bar device is made up of two draw bars, two connecting lever assemblings, a pipe link and their keying.Wherein the intermediate ends of connecting lever assembling links to each other with the truck frame curb girder by the connecting lever pin, the inner end of connecting lever assembling links to each other with pipe link by connecting lever pin, the outer end of draw bar links to each other with car frame side beam by towing pin, the inner end of draw bar links to each other by the outer end of towing pin and connecting lever assembling, thus the purpose of realization draw bar device transmitting tractive power and braking force between truck frame and vehicle frame.
Because towing pin is a rigid construction, need carry by the rigidity oscillating bearing, the gap that exists between towing pin and the oscillating bearing is easy to generate impact like this, thereby influences the transmission of tractive force and braking force.And in use have wear problem, and make the gap grind bigger and bigger, can further influence the transmission of tractive force and braking force, though regularly can add lubricating oil, can't be from deal with problems at all.
The utility model content
The purpose of this utility model is to overcome the problems referred to above, and the plane leverage draw bar device of a kind of better transmitting tractive power and braking force is provided.
The technical scheme that realizes the utility model purpose is: a kind of plane leverage draw bar device, comprise two draw bars, two connecting levers assemble and pipe link, the intermediate ends of connecting lever assembling links to each other with the truck frame curb girder by the connecting lever pin, the inner end of connecting lever assembling links to each other with pipe link by connecting lever pin, the inner end of draw bar links to each other by the outer end of rubber spherical joint with the connecting lever assembling, and the outer end of draw bar links to each other with car frame side beam by rubber spherical joint.
Described rubber spherical joint comprises spheroid, covers the rubber layer of outer surface of spheroid and covers the outer wire loop of rubber layer.
Also have two strip metal pads between described rubber layer and the wire loop.
The utlity model has positive effect: plane of the present utility model leverage draw gear has replaced towing pin and oscillating bearing with rubber spherical joint, make and do not have the gap in being connected of draw bar and car frame side beam and connecting lever assembling, also avoided the sassafras loss that rubs, make flat draw bar device better transmitting tractive power and braking force like this, improved the riding quality of locomotive.And this position is also maintenance free in the life cycle of rubber, has prolonged the service life of draw bar device
