Description
Technical Field
The utility model relates to a rail train braking technical field especially relates to a rail transit is brake block for train.
Background
The monorail is generally used in domestic and foreign cities due to the advantages of small occupied space, low manufacturing cost, short construction period and the like, but the monorail uses independent rails, two balance rails of a non-traditional railway have larger and larger braking load along with the continuous increase of the speed of the train, and the requirement on the strength of a brake pad is higher and higher;
at present, the single-rail brake pad is commonly synthesized into an integral brake pad, so that the brake pad is not resistant to high temperature when a train brakes, and the high-temperature brake pad is in rigid contact with a friction surface in the braking process, so that the abrasion and deformation of the brake pad are serious, even the brake pad cracks, and the normal braking of the train in the running process is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem that the prior art does not have high temperature resistance, and provides a brake pad for rail transit train.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a brake lining for track traffic train, includes the backplate, the equal fixed mounting in both ends of backplate has the go-between, two the guiding hole has all been seted up to one side of go-between, two the guiding hole is located the both ends of backplate respectively, fixed mounting has a plurality of friction bodies on the roof of backplate, the friction body is fan-shaped evenly distributed on the backplate, the internal equal fixed mounting of friction has the heat conduction piece, the heat conduction piece all runs through the backplate, on the same fan-shaped cambered surface the bottom fixed mounting of heat conduction piece has the heating panel, the heating panel is the arc structure, the heating panel distributes along vertical direction equidistance.
Preferably, the back plate is of a symmetrical fan-shaped plate structure, and the radian of the back plate is the same as that of the heat dissipation plate.
Preferably, the bottom of the friction body is fixedly provided with a threaded head, the back plate is provided with a threaded groove matched with the threaded head, and the threaded head is in threaded connection with the inner wall of the threaded groove.
Preferably, the thread head is sleeved with a corresponding elastic gasket.
Preferably, a plurality of heat dissipation holes are formed in the middle of the back plate.
The utility model provides a pair of brake pad for rail transit train, beneficial effect lies in: when the friction body is in the braking process, the generated high-temperature heat is guided to the heat dissipation plate by the heat conduction block, the heat dissipation plate can be in large-area contact with air to dissipate heat, meanwhile, the heat dissipation hole can accelerate the contact of the air and the heat dissipation plate, and therefore the heat on the surface of the friction body is rapidly released, the friction body is prevented from being abraded by high temperature, and the service life of the friction body is prolonged.
