Problems solved by technology
In related technologies, the traction connection between the bogie and the vehicle body is mainly realized through the central traction pin assembly. During driving, the power of the running wheels is transmitted to the bogie frame, and then the traction force is transmitted to the vehicle through the central traction pin assembly. However, this traction mechanism is only suitable for two-axle bogies, and cannot suppress the pitching motion of the bogies. The structure is complicated, and it takes up a lot of installation space, so there is room for improvement.

The invention discloses a traction mechanism, a bogie assembly and a straddle type monorail vehicle. The traction mechanism includes: a traction assembly, the traction assembly includes a traction link, a lower crank and a drive shaft, and the traction link is suitable for It is hinged with the bogie frame, the outer end of the lower crank is hinged with the traction link, and the other end of the lower crank is fixedly connected with the transmission shaft, and the transmission shaft is suitable for being rotatable with the car body. ground connection; traction crank, the two ends of the traction crank are adapted to be respectively hinged with the bogie frame and the vehicle body. The traction mechanism of the present invention has a simple and compact structure, short transmission path of traction force, convenient disassembly and assembly of the traction mechanism, small space occupation, wide application range of the traction mechanism, can be used for low-floor and high-floor vehicles, and is also suitable for single Axle bogies, double-axle bogies and multi-axle bogies.
Description
technical field [0001] The invention belongs to the technical field of vehicle manufacturing, and in particular relates to a traction mechanism, a bogie assembly with the traction mechanism, and a straddle monorail vehicle with the bogie assembly. Background technique [0002] The laying cost of the straddle-type monorail transportation system is much lower than that of the subway transportation system, and its application range is wider. Among them, the traction mechanism between the car body and the bogie frame is an important transmission part of the straddle monorail vehicle, and its performance directly affects the safety and ride comfort of the straddle monorail vehicle. In related technologies, the traction connection between the bogie and the vehicle body is mainly realized through the central traction pin assembly. During driving, the power of the running wheels is transmitted to the bogie frame, and then the traction force is transmitted to the vehicle through the ...
