Abstract

The invention discloses a motor train unit elastic daub buffering device. The motor train unit elastic daub buffering device comprises a pull head, a pull head base, a top plate, an inner piston rod assembly, an outer piston rod assembly, a cylinder body, a cylinder cover assembly, a pull sleeve assembly, a back pull ring and an outer cylinder assembly. Through adoption of the characteristics of inner and outer double piston rod structures, two-stage dynamic static damping ratio, a flat key and plane two-state anti-rotation mechanism, a split type positioning ring as well as alternating use ofthe first and second sealing piece double-seal structures under the static and dynamic states, the motor train unit elastic daub buffering device has the advantages of stable property, sealing reliability, high low-temperature property, high adsorption rate, long life, low manufacturing cost and the like.

Description

technical field [0001] The invention relates to a buffer device for couplers of rail transit equipment, in particular to an elastic cement buffer device for concentrated power standard EMU locomotives and vehicles, and belongs to the technical field of rail transit equipment. Background technique [0002] As one of the important components of railway equipment, the buffer device is mainly used to transmit traction, moderate impact force, reduce vibration, absorb impact kinetic energy, reduce longitudinal impulse, and improve the longitudinal dynamic performance of trains. In recent years, with the rapid development of rail transit equipment, the types of buffer devices installed are moving towards diversification and serialization. The comprehensive performance of the buffer device directly affects the running quality of the train, the traction weight, the reliability of the car body structure, etc. A good buffer device can effectively reduce the force of the coupler, reduc...
