technical field

The utility model relates to the technical field of urban rail vehicles, in particular to a bogie of a straddle type monorail vehicle.

Background technique

In a rail vehicle, the bogie refers to the part of the rail vehicle that is responsible for carrying, transferring the weight of the vehicle body and guiding it. It is one of the most important components of the rail vehicle and is of great significance to the safe operation of the rail vehicle. The reliability of the bogie structure is an important factor to ensure the safety of the vehicle. Various parameters of the bogie directly determine the safety and ride comfort of the vehicle. The traditional straddle-type monorail bogie has a complex structure and heavy weight. The running wheels are fixed on the bogie, which makes it difficult to serve on small-radius curved lines and has poor adaptability to line distortion. The running wheels wear seriously during operation, and the operation and maintenance costs are relatively high. In addition, due to the large mass of the spring loaded on the damping spring, the force transmitted to the wheel and the track becomes larger, and the running performance is poor.
