Improved pure electric highway-railway dual-purpose vehicle

Abstract

The invention relates to an improved pure electric road-rail car which mainly comprises a car body capable of bearing loads, road wheels powered by a storage battery and driven by a hub motor, rail steel wheels driven by gears and capable of running on a steel rail, a rotatable large arm used for switching different running states of the road and the rail, and a limiting device capable of automatically locking the large arm. The road wheel is characterized in that in a road state, the hub motor independently drives the road wheel to rotate. In a railway state, the road wheels rotate synchronously, and the driving gears coaxially mounted on the inner sides of the road wheels are transmitted to the meshed driven gears to drive the coaxially mounted rail steel wheels to rotate. When a highway state is switched to a railway state, the limiting device can automatically lock the large arm at a fixed position in a power-off state, and tight meshing transmission of the driving gear and the driven gear is guaranteed. When the railway state is switched to the highway state, the large arm can be unlocked only after the limiting device is powered on by the switching power supply, and the reliability and the safety when the vehicle is switched to the highway state from the railway state are guaranteed.

Description

technical field [0001] The invention relates to a road-rail dual-purpose multi-purpose vehicle, in particular to an improved road-rail dual-purpose vehicle using pure electric power, which belongs to the technical field of green transportation equipment. Background technique [0002] The road-rail vehicle is a special vehicle that can quickly switch between the two operating states of the road and the track, and can run on the ordinary road or on the track. Highway and railway vehicles are flexible, versatile, and convenient to use. They can be used in urban rail transit, railway depots, mining, ports, warehousing and logistics industries such as rail vehicle traction and shunting, railway engineering construction, emergency rescue, and cargo transfer. And other application fields, the applicability is good. Foreign road-rail vehicles have been put into research earlier. At present, Germany, the United States, Japan and other countries have the world's leading level in the ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to address the shortcomings and deficiencies of the above-mentioned common road-rail vehicle design scheme, and propose an improved pure electric road-rail vehicle technical solution to alleviate the power of several existing internal combustion engine road-rail vehicles. The device is single, the chassis structure and the driving and switching devices for road and rail are relatively complex, there are problems such as environmental pollution and noise, and the cost of daily operation and post-maintenance is high
