The invention discloses a traction suspension composite mechanism of a bogie, including secondary side bearings arranged on the surface of the frame on both sides, secondary traction cylinders sleevedon the surface of the secondary side bearings, a traction mount is arranged on the surface of the frame on both sides, and a traction rod connected between the secondary traction cylinders and the traction mount for transmitting the traction force of the frame to the secondary traction cylinders, wherein the surface of the each secondary traction cylinder is connected with the vehicle body chassis, and the secondary side bearings have elasticity in both axial and radial directions. The traction suspension composite mechanism disclosed by the invention can reduce the occupied space on the bogie on the basis of ensuring the normal suspension and traction function of the bogie, can improve the utilization rate of the space on the bogie, and can facilitate the installation and arrangement ofthe safety monitoring components. The invention also discloses a bogie and a rail transit vehicle, the beneficial effects of which are described above.
Description
technical field [0001] The invention relates to the technical field of rail transportation, in particular to a traction and suspension composite mechanism of a bogie. The invention also relates to a bogie and a rail transit vehicle. Background technique [0002] With the development of China's machinery industry, more and more machinery and equipment have been widely used. [0003] In the field of rail transit, due to the high speed of vehicles, the requirements for vehicle safety performance are more stringent. For rail vehicles, the safety performance of the bogie is particularly important, which leads to more and more safety monitoring equipment that needs to be arranged on the bogie, such as axle temperature detection system, obstacle detection system, gearbox temperature rise monitoring system, etc. At the same time, in order to meet the requirements of high passenger capacity and fast start and stop, the bogie needs to be equipped with huge magnetic rail braking equi...
