Road-rail car driven by rubber wheels

Abstract

The invention provides a road-rail car driven by rubber wheels. The road-rail car driven by rubber wheels comprises a car frame. Rotary rubber-wheel sets are arranged at the front end and the rear end of the car frame correspondingly, and each rubber-wheel set comprises two car wheels; the convertible car for the highways and the railways driven by the rubber wheels is characterized in that each rubber-wheel set is provided with a railway guiding device, and the railway guiding device comprises an upper rotary seat, a lower rotary seat and guide wheels capable of lifting; bearings are arranged between the upper rotary seat and the lower rotary seat, a restoring plate extending downwards is arranged at the bottom of the upper rotary seat, and a plurality of rubber blocks are arranged on the lower rotary seat; the multiple rubber blocks are symmetrically arranged on the two sides of the restoring plate, the restoring plate is clamped among the rubber blocks, and the guide wheels are arranged on the lower rotary seat; and the upper rotary seat is fixed at the bottom of the car frame, and the railway guiding device is located.between the two car wheels of the corresponding rubber-wheel sets. And thus, the curve passage capacity and the universality of the road-rail car driven by rubber wheels are improved.

Description

technical field [0001] The invention relates to a railway and highway vehicle, in particular to a road-rail vehicle driven by rubber tires. Background technique [0002] At present, the dual-purpose vehicle for railway and highway is widely used in the rail transportation industry because it can run on both the road and the railway. Among them, the dual-purpose vehicles driven by rubber tires are usually used for railway traction, emergency repair, construction and emergency operations. The dual-purpose vehicles in the prior art are mainly improved on the basis of existing automobiles. The guide device can be used on the railway. Chinese Patent No. 201210554322.1 discloses a guide wheel mechanism and a dual-purpose railway and road vehicle, wherein the guide wheel mechanism includes components such as a guide wheel, an oil cylinder and an oil cylinder frame, and the guide wheel is driven by the oil cylinder to realize lifting. The guide wheel mechanism is fixed on the car t...

AI Technical Summary

Problems solved by technology

However, in actual use, when a dual-purpose vehicle for railway and highway passes through a curve on the rails, it is limited by its own structural form and connection mode, so the requirements for the turning radius of the curve are relatively large, and the minimum curve radius of the railway that can pass is 35m, unable to meet the requirements of 25m curved lines in subway and tram depots, resulting in poor curve passing ability and versatility of railway guide devices in the prior art
