Problems solved by technology

[0002] In the prior art, the suspension system of road-rail vehicles is mainly composed of laminated springs or circular springs. This type of suspension system has the following disadvantages: the suspension system can only be passively stressed, and its spring compression cannot be adjusted. Therefore, the vehicle In the case of no load and heavy load, the load on the left and right sides is unbalanced, which will cause a relatively large inclination, which will affect driving safety.
Therefore, road-rail vehicles in the prior art are generally only suitable for working conditions with a speed of less than 20km / h.

Abstract

The invention relates to a road and railway dual purpose vehicle, which comprises a highway travel system, a railway travel system and a suspension system arranged on the highway travel system and railway travel system. The suspension system comprises a suspension device composed of an air spring and a height regulation mechanism, and the height of the air spring is regulated by regulating the air amount charged in the air spring. The combined vehicle has the advantages that the air suspension system is used to actively level the height of the left-right two sides of the vehicle body to guarantee the driving safety without roll-over, according to regulating the charging of the air amount in the air spring arranged on different wheel pairs, the distribution of the axle load of the lifting transport vehicle of the highway and railway under the conditions of highway or railway, no-load or heavy-load can be regulated.

Description

technical field [0001] The invention relates to a road-rail dual-purpose vehicle that uses air springs as load-bearing springs and can run on both roads and railways. Background technique [0002] In the prior art, the suspension system of road-rail vehicles is mainly composed of laminated springs or circular springs. This type of suspension system has the following disadvantages: the suspension system can only be passively stressed, and its spring compression cannot be adjusted. Therefore, the vehicle In the case of no load and heavy load, the load on the left and right sides is unbalanced, which will cause a relatively large inclination, which will affect driving safety. Therefore, the road-rail vehicle in the prior art is generally only applicable to the working condition that the vehicle speed is less than 20km / h. Contents of the invention [0003] The purpose of the present invention is to provide a road-rail dual-purpose vehicle which can automatically level the bod...
