Central cross beam type traction device

Abstract

The invention relates to a central cross beam type traction device. The central cross beam type traction device replaces the swing bolster transmission structure in the prior art, and can effectively reduce the entire weight of a steering frame, simplify the traction structure to be convenient for repair, reduce the energy consumption in the transmission process of longitudinal traction force, andcontrol and reduce the generation of running noise. The central cross beam type traction device is provided with a central cross beam for connecting framework side beams on two sides, the side part of the central cross beam is provided with a base of a longitudinal pulling rod connected with a longitudinal traction rod, and the longitudinal traction rod is connected with a linear motor. The central cross beam is provided with a base of a traction pulling rod, which is used for connecting with the traction pulling rod, and the traction pulling rod is connected with a traction beam. A central pin upwardly connected with a vehicle body is respectively connected with a traction beam and the central cross beam in penetration. The longitudinal traction force is directly transmitted to the central cross beam by the linear motor through the longitudinal traction rod, and the traction beam through the traction pulling rod, and the traction beam transmits the longitudinal traction force to thevehicle body through the central pin to realize the purpose of driving the vehicle body by the linear motor.

Description

technical field [0001] The invention relates to a traction device for rail vehicle bogies, belonging to the field of mechanical manufacturing. Background technique [0002] The linear motor bogies currently used in rail vehicles generally adopt a bolster structure to transmit the longitudinal traction force transmitted from the linear motor to the vehicle body. The traction force of the linear motor is transmitted to the frame through the longitudinal drawbar, then to the bolster through the drawbar, and finally to the car body through the central pin. [0003] The braking force is transmitted to the frame by the wheel set, then to the bolster, and finally to the car body through the center pin. , [0004] Due to the large mass of the bogie, the bogie structure using the bolster traction method is also relatively complicated, which brings cumbersome parts maintenance process and increases the energy consumption in the process of longitudinal traction transmission.
