Abstract

The invention discloses a highway and railway dual-purpose vehicle, which comprises a vehicle body, and further comprises a non-power running portion and a power running portion installed below the vehicle body. The non-power running portion comprises a framework, a traction lifting device and a non-power wheel pair axle box positioning device and braking devices. The power running portion comprises the framework, the traction lifting device, a power wheel pair axle box positioning device and driving devices. The non-power wheel pair axle box positioning device comprises an axle and a pair offirst wheels arranged on the axle. The braking devices are arranged at the both ends of the axle and on the inner sides of the first wheels. The power wheel pair axle box positioning device comprisesa crankshaft and a pair of second wheels arranged on the crankshaft. The driving devices are arranged at the both ends of the crankshaft. The highway and railway dual-purpose vehicle solves the problems that in the prior art the operation speed is slow, the weight is heavy, the running stability is poor, and a large space under the vehicle is occupied.

Description

technical field [0001] The invention relates to the field of transportation machinery, in particular to a dual-purpose vehicle for road and rail. Background technique [0002] The running part is the part where the vehicle runs along the line under the action of traction power. The function of the running part is to ensure that the vehicle runs flexibly, safely and smoothly along the rail and through the curve; reliably withstands various forces acting on the vehicle and transmits them to the rail; eases the mutual impact between the vehicle and the rail, reduces vehicle vibration, and ensures sufficient smooth operation and good running quality; with a reliable braking mechanism, the vehicle has a good braking effect. [0003] At present, the running parts of domestic road and rail vehicles have disadvantages such as slow running speed, heavy weight, poor running stability, and large space under the vehicle. The highest operating speed in China is 80km / h, mostly in the fo...
