Wheel type public transport and railway dual-purpose chassis and public transport and railway dual-purpose vehicle

By designing a combination of steel wheels and rubber wheels, the steel wheels roll on the steel rails, solving the problems of derailment and slippage in rainy or snowy weather that are common in dual-purpose road and rail vehicles. This achieves highly stable and safe track operation, making it suitable for travel and construction work under complex conditions.

AI Technical Summary

Technical Problem

Existing dual-purpose road and rail vehicles are prone to derailment when running on tracks, especially in rainy or snowy weather when the friction coefficient decreases, affecting traction and braking safety.

Method used

The design employs a combination of steel wheels and rubber wheels. The steel wheels roll on the steel rails, while the rubber wheel assembly drives the steel wheels, avoiding direct contact between the rubber wheels and the steel rails. By utilizing the low rolling resistance and strong guiding properties of the steel wheels, the stability and safety of the vehicle on the track are ensured.

Benefits of technology

It improves the stability and safety of dual-purpose road and rail vehicles on the track, enhances traction and braking capabilities, reduces maintenance costs, and adapts to traffic and construction operations under complex conditions.

Abstract

The utility model relates to a kind of wheel type public rail dual-purpose chassis and public rail dual-purpose vehicle.Wheel type public rail dual-purpose vehicle includes frame, four steel wheel assemblies, two steel wheel frames, four rubber wheel frames and four rubber wheel assemblies, when using on track, steel wheel is contacted with steel rail, four rubber wheel assemblies are respectively one-to-one correspondingly pressed on four steel wheels, steel wheel can roll on steel rail under the rotating action of rubber wheel assembly, to realize the walking of public rail dual-purpose vehicle on track, so rubber wheel assembly will not be directly contacted with steel rail, avoid the emergence of the security problems such as easy derailment in running process, easy to skid under rain and snow weather, thereby affecting vehicle traction and braking, and rubber wheel is directly contacted with steel rail, because the rolling resistance of steel wheel is extremely low, steel wheel has inherent directivity, steel wheel has strong carrying capacity, steel wheel has high running stability when walking on track, so public rail dual-purpose vehicle has high use safety, and also has strong carrying capacity.
