Vehicle rubber buffer

Abstract

A vehicle rubber buffer includes a protective housing, a first reinforcing plate is rotatably connected to a side of the first threaded rod away from the protective housing, a cushion shell is fixedlyconnected with that middle symmetrical positions of the inner walls on both sides of the protective shell, a cushion rubber is fixedly connected to the middle position of the fixed partition plate onthe side far away from the protective shell, the cushioning rubber inner cavity is provided with a cushioning spring, a rubber cushion auxiliary device is slidably connected with the inner surface ofthe cushion chute, a cushion rod is slidably connected with the buffer shell at a middle position on a side far away from the fixed partition plate, and a second reinforcing plate is rotatably connected with a side far away from the protection shell. The invention relates to the technical field of vehicle rubber cushion. The buffer effectively expands the occupying volume of rubber and spring, increases its cushioning performance, ensures its cushioning efficiency, and cushions with multiple structures, reduces the pressure of internal components, and ensures the service life of the device.

Description

technical field [0001] The invention relates to the technical field of vehicle rubber buffers, in particular to a vehicle rubber buffer. Background technique [0002] Railway vehicles are connected to each other through couplers. During operation and marshalling, a large impact force will be generated between the connected couplers and the car body. For this reason, a buffer device with a buffer as the main body must be provided between the coupler and the car body to achieve shock absorption and noise reduction functions and improve vehicle performance. The existing vehicle rubber buffer has complex structure, heavy weight, and high manufacturing cost. During maintenance, it needs to be cut with a cutting machine. , The rear steel seat not only greatly increases the weight of the buffer, but also occupies the buffer space of the buffer frame, so that when the existing buffer transmits the same impact force, the stress intensity of the rubber increases, resulting in poor bu...
