Abstract

The invention discloses a railway running portion and a rail-road vehicle. The railway running portion includes a first framework, a wheel set axle box positioning device, a drive device, a brake device, a second suspension traction device, and a lifting device; the first framework is arranged between a first spring and a second spring; a second framework is arranged between the second spring andthe lifting device; and the lifting device is cross-shaped and adopts an electrical pushing rod. The problem that the conventional railway running portion is low in operation speed, is heavy, is poorin operation stability, and is large in occupied space under the vehicle in the prior art can be solved.

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...
