Abstract

The invention provides a bogie. The bogie comprises a framework, a transverse shock absorber, a traction pull rod, a traction beam and a center pin, wherein one end of the transverse shock absorber is fixed to the framework, the traction pull rod is fixed to the framework, the traction beam is fixed to the traction pull rod, and the center pin is fixed to the traction beam. The center pin is also connected with a vehicle body simultaneously, and thus, the vehicle body and the bogie can be connected together through the center pin and the traction beam. The other end of the transverse shock absorber is fixed to the traction beam through a transverse shock absorber support, the impact load is absorbed through the transverse shock absorber, and the taking comfort degree is well promoted. The transverse shock absorber support and the traction beam are of an integrated structure, and the assembly welding process of the traction beam of the integrated structure is omitted, so that the production efficiency is improved. Stress concentration generated by assembly welding is avoided, the strength of the traction beam is improved, and the powerful guarantee is provided for safe operation of a train. The invention further provides a rail vehicle.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a bogie and a rail vehicle with the bogie. Background technique [0002] With the popularity of high-speed rail, people have put forward higher and higher requirements for the ride comfort of high-speed rail. High-speed rail engineers have put forward higher requirements for the manufacturing process of trains on the basis of meeting the needs of passengers. [0003] The bogie and the car body are the main components of the train. The part connecting the car body and the bogie is called the traction device. The quality of the traction device is not only related to the safety of the train but also directly related to the comfort of the passengers. Therefore, How to ensure the quality of the traction device, make the traction device better transmit kinetic energy while reducing manufacturing costs, and simplify the installation process is the subject of research by technician...
