Abstract
The utility model discloses a novel composite material friction plate and relates to the technical field of wagon bogie vibration reduction. An enhancement layer is composed of a plane and a cylinder, small round holes are formed in a cylindrical surface at one end of the cylinder, the plane is arranged at the bottom of the other end of the cylinder; a wearing layer is in tight fit with the bottom of the plane, and a U-shaped groove is formed in the middle of the wearing layer. By the novel composite material friction plate, the static rigidity and the movable rigidity of the bogie are favorably increased, the abrasion between heavy haul train wheel tracks is effectively reduced, the operation cost of the heavy haulage is reduced, the high-frequency vibration between the wheel tracks is isolated, the vertical dynamics performance of trains is improved, the running stability of trains is improved, the fatigue service life of parts such as a side frame is favorably improved, and the stability of snake movement of the bogie can be controlled.
Description
Technical field:
The utility model relates to the railway goods train bogie antivibration area, be specifically related to that bogie side frame in roller bearing adapter stabilizer bar forms and bolster in a kind of advanced composite material friction plate.
Background technology:
Along with advancing by leaps and bounds of market economy, the step of social development is constantly accelerated, and people also require more and more higher to the demand of the energy and material, more and more the promptness practicality, in order to satisfy the daily required of customer, railway freight is a very economical, quick, safe transportation mode.Undeniable, the High Performance that improves goods train is the current most important thing.
Bogie truck is goods train requisite Infrastructure in service, the quality of its quality directly affects speed and the safety of train, train is more steady when running at high speed, vibratory sensation is smaller in order to make, generally to improve the sound rigidity of lorry, but because train constantly raises speed, present only depend General Purpose Rubber spare elasticity alone and can not play good cushioning effect, rigidity is difficult to arrive the high speed requirement, special in the train of speed per hour higher than 200Km, this common rubber damper can not satisfy the train requirement of synchronized development.
Train produces in the train of running at high speed momentum and kinetic energy are larger, and that train vibrations are jolted is more severe if the effectiveness in vibration suppression of bogie truck is bad, also may make to have potential safety hazard in train driving; Require the quiet rigidity of vibration isolation rubber spare of bogie truck larger in the train of running at high speed, and the ratio of sound rigidity requires to reduce, and only have Rubber Parts, its rigidity is difficult to also just can not guarantee the steady and safety of high speed goods train to requiring.
The utility model content:
The purpose of this utility model is to provide a kind of advanced composite material friction plate, it is conducive to increase quiet rigidity and the dynamic stiffness of bogie truck, effectively reduce the abrasion between the heavy haul train wheel track, reduce the operation cost of heavy haul transport, isolate high-frequency vibration between wheel track, improve the vertical dynamics performance of vehicle, improve the running stability of vehicle, be conducive to improve the fatigue life of the parts such as bogie side frame, the hunting stability of bogie truck is had controlled effect.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises friction plate body 1, and friction plate body 1 is comprised of wearing layer 2 and enhancement layer 3; Enhancement layer 3 is comprised of plane 3-1 and cylinder 3-2, and the cylinder of cylinder 3-2 one end is provided with small sircle hole 3-3, and plane 3-1 is arranged on the bottom of the cylinder 3-2 other end, and wearing layer 2 fits tightly bottom the 3-1 of plane, and is provided with U-lag 2-1 in the middle of wearing layer 2.
Described wearing layer 2 can compensate the integral rigidity of bogie truck.
Described enhancement layer 3 is in order to be fixed on the intensifier on bogie side frame in conjunction with described wearing layer.
The heat that described U-lag 2-1 can make friction plate body 1 produce in friction process is easy to distribute.
Described small sircle hole 3-3 is convenient to friction plate body 1 and can be installed on vehicle frame.
The utility model is conducive to increase quiet rigidity and the dynamic stiffness of bogie truck, effectively reduce the abrasion between the heavy haul train wheel track, reduce the operation cost of heavy haul transport, high-frequency vibration between the isolation wheel track, improve the vertical dynamics performance of vehicle, improve the running stability of vehicle, the fatigue life that is conducive to improve the parts such as bogie side frame, the hunting stability of bogie truck is had controlled effect.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment:
See figures.1.and.2, this concrete enforcement by the following technical solutions: it comprises friction plate body 1, and friction plate body 1 is comprised of wearing layer 2 and enhancement layer 3; Enhancement layer 3 is comprised of plane 3-1 and cylinder 3-2, and the cylinder of cylinder 3-2 one end is provided with small sircle hole 3-3, and plane 3-1 is arranged on the bottom of the cylinder 3-2 other end, and wearing layer 2 fits tightly bottom the 3-1 of plane, and is provided with U-lag 2-1 in the middle of wearing layer 2.
Described wearing layer 2 can compensate the integral rigidity of bogie truck.
Described enhancement layer 3 is in order to be fixed on the intensifier on bogie side frame in conjunction with described wearing layer.
The heat that described U-lag 2-1 can make friction plate body 1 produce in friction process is easy to distribute.
Described small sircle hole 3-3 is convenient to friction plate body 1 and can be installed on vehicle frame.
This specifically implements and is beneficial to quiet rigidity and the dynamic stiffness that increases bogie truck, effectively reduce the abrasion between the heavy haul train wheel track, reduce the operation cost of heavy haul transport, high-frequency vibration between the isolation wheel track, improve the vertical dynamics performance of vehicle, improve the running stability of vehicle, the fatigue life that is conducive to improve the parts such as bogie side frame, the hunting stability of bogie truck is had controlled effect.
