Abstract

The invention discloses a railway running part and a road and railway dual-purpose vehicle. The railway running part includes a frame, a wheelset axle box positioning device, a central suspension traction lifting device, a braking device and a driving device. The frame includes cross beams and side beams. The wheelset axle box positioning device includes axles, wheels and a transmission device. The central suspension traction lifting device includes air springs, traction pull rods, lifting shock absorbers, traction pins, transverse stoppers and locking devices. The railway running part solvesthe problems that in the prior art, the running speed is slow, the weight is high, the running smoothness is poor, and the occupied space under the vehicle is large.

Description

technical field [0001] The invention relates to the field of transportation machinery, in particular to a railway running part and a dual-purpose vehicle for road and rail. Background technique [0002] At present, most of the running parts used in road and railway vehicles in China are in the form of two-axle bogies, which have the characteristics of slow running speed, heavy weight, poor running stability, and large space under the car. The running speed is up to 80km / h. [0003] It is a problem to be solved urgently to develop a new type of running part applied to road and rail dual-purpose vehicles to solve the disadvantages of slow running speed, heavy weight, poor running stability and large space under the vehicle in the prior art. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a railway running part and a dual-purpose vehicle for road and rail, which solves the problems of slow running speed, heavy weigh...
