Abstract

The embodiment of the invention provides a bogie and a rail vehicle. The bogie comprises: side beams, wherein the number of the side beams is two, and the two side beams are parallel and arranged sideby side; a wheel set arranged below the side beams, wherein the wheel set comprises an axle, wheels symmetrically arranged on the axle and axle boxes symmetrically arranged on the axle. a primary suspension device arranged between the side beams and the axle box; and a safety stop device arranged at the top of the primary suspension device. According to the bogie and the rail vehicle, it can be guaranteed that the vehicle body load is borne through the safety stops when the side beams fail, and driving safety is guaranteed.

Description

technical field [0001] The present application relates to rail vehicle running technology, in particular to a bogie and a rail vehicle. Background technique [0002] Rail vehicles are an important transportation link connecting cities, and have gradually become the main means of transportation in cities. Rail vehicles are also the main carrier for cargo transportation. A rail vehicle mainly includes: a car body and a bogie arranged under the car body. The bogie is used to carry the car body and realize the running and steering functions. [0003] The bogie includes structures such as frame, wheelset, traction device, and primary suspension device. The frame includes two side beams extending along the length of the vehicle and a beam connecting the two side beams. Between the axle box in the wheel set, it is used to buffer the vibration between the side beam and the wheel set. During operation, when the side beam fails due to fracture and deformation, it will lead to the ov...
