Buffer rubber sleeve for railway carriage bogie

Abstract

The utility model discloses a buffer rubber sleeve for a bogie of a passenger train, which comprises a rubber sleeve main body, and a rigid spring is mounted in the middle of the rubber sleeve main body. According to the buffer rubber sleeve, the rigid spring is additionally arranged in the middle of the rubber, the vertical rigidity of the buffer rubber sleeve is increased, the transverse rigidity of the buffer rubber sleeve is increased, high compression of a product after being assembled is effectively guaranteed, the problem that installation is affected due to size creep reduction after a pure rubber part is used for a long time can be solved, and the service life of the buffer rubber sleeve is prolonged.

Description

Technical Field

[0001] The utility model relates to the technical field of railway passenger cars, in particular to a buffer rubber sleeve for a railway passenger car bogie. Background Art

[0002] Railway passenger car bogie buffer rubber sleeve is an important shock-absorbing component of the bogie axle box and frame of rail transit vehicles, and is widely used in urban rail trains such as subways and light rails. The main function is to mitigate and attenuate vehicle vibration and impact, make the vehicle run smoothly, and improve the train ride comfort.

[0003] Traditional buffer rubber sleeves are made of pure rubber vulcanized, and use rubber to carry and cushion. However, after long-term loading, rubber will creep and its size will continue to shrink, thus affecting the assembly of the structure. The traditional buffer rubber sleeve structure can no longer meet the design requirements of the bogie, which puts forward new requirements for the structure of the buffer rubber sleeve. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a buffer rubber sleeve for a railway passenger car bogie. The device adds a rigid spring in the middle of the rubber, increases the vertical stiffness of the buffer rubber sleeve, increases the lateral stiffness of the buffer rubber sleeve, effectively ensures the compression height of the product after assembly, avoids the problem of the pure rubber part creeping and shrinking in size after long-term use, and affects the installation, thereby extending the service life of the buffer rubber sleeve.

[0005] The utility model also provides the above-mentioned buffer rubber sleeve for railway passenger car bogie, comprising: a rubber sleeve main body, and a rigid spring is installed in the middle of the rubber sleeve main body.

[0006] According to the buffer rubber sleeve for a railway passenger car bogie, the rubber sleeve main body is formed by vulcanizing rubber.

[0007] According to the buffer rubber sleeve for a railway passenger car bogie, the rigid spring is added into the rubber during the vulcanization process of the rubber sleeve body.

[0008] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
