Problems solved by technology

[0004] Due to the limitation of the internal space of the bogie frame, the traditional suspended monorail vehicle bogie traction device transmits the traction and braking force through the center pin, the center pin seat and the traction rubber stack. When the lateral force is relatively large, it also passes the center pin outside The rubber stack is transmitted to the frame. This structure is greatly affected by rubber creep and has a relatively short service life. At the same time, the center pin of this structure needs to bear a relatively large force and has relatively poor stability.

Abstract

The invention provides a traction device for a suspended monorail vehicle. The traction device is fixedly connected with a sleeper beam above a bogie frame. The traction device comprises a center pin inserted into the center of the interior of the bogie frame, and a traction base connected to the lower end of the center pin in a sleeving mode, wherein a connecting plate is arranged on the traction base, parallel traction pull rods are arranged at the two ends of the connecting plate perpendicular to the connecting plate in a zigzag mode, one end of each traction pull rod is hinged to the connecting plate of the traction base, the other end of each traction pull rod is hinged to a traction pull rod installation base, an elastic element is arranged at the position where the center pin is connected with the traction base in the sleeved mode, and an elastic transverse stopping block is transversely arranged inside the bogie frame. According to the traction device, large transverse force is transmitted through the elastic transverse stopping block and the center pin; the movement of a vehicle body relative to a bogie is fully guaranteed by means of an elastic rubber joint through the traction device provided with the center pin and the two pull rods arranged in the zigzag mode; meanwhile, the characteristic of the traction pull rods arranged in the zigzag mode that centering performance is high is fully utilized, traction force and braking force are well transmitted, and the curve passage capacity of the vehicle is improved.

Description

technical field [0001] The invention relates to the field of traction devices for monorail vehicles, in particular to a traction device for a bogie of a suspended monorail vehicle. Background technique [0002] The traction device of the bogie of the suspended monorail vehicle is an important mechanism connecting the car body and the bogie. On the car body, at the same time, the center pin transmits the vertical force of the vehicle to the running wheels. Whether the design of the traction device is reasonable or not is directly related to the quality of vertical force and longitudinal force transmission. The design of the traction device must meet the requirements of kinematics, dynamics, safety, etc. at the same time. [0003] Since the bogie moves in all directions relative to the car body, a traction device with a reasonable structure must ensure that it does not interfere with the relative movement of the bogie and car body when the vehicle is running normally. At the...
