Guide wheel mechanism and autorailer

Abstract

The invention provides a guide wheel mechanism and an autorailer. The guide wheel mechanism comprises two guide wheels which are connected together through an axle, axle blocks are arranged on the axle, and each guide wheel is correspondingly provided with a guide link mechanism which comprises an oil cylinder holder, a sliding support, a first rotating arm, a second rotating arm and an oil cylinder; the oil cylinder holders are fixed on a chassis of the autorailer, the bodies of the oil cylinders are articulated with the oil cylinder holders, the sliding supports are horizontally and slidably connected with the oil cylinder holders, the piston rod of each oil cylinder is articulated with one end of the related sliding support, the upper ends of the first rotating arms are articulated with the chassis, the upper ends of the second rotating arms are articulated with the other ends of the sliding supports, the lower ends of the first rotating arms are articulated with the middles of the second rotating arms, and the axle blocks are fixed on the lower ends of the second rotating arms. By means of the guide wheel mechanism, the reliability of the autorailer is enhanced.

Description

technical field [0001] The invention relates to mechanical equipment for vehicles, in particular to a guide wheel mechanism and a dual-purpose railway and road vehicle. Background technique [0002] At present, the dual-purpose vehicle for railway and road is widely used in the rail transportation industry because it can run on both the road and the railway. The dual-purpose vehicle for railway and highway is usually used for operations such as railway traction, emergency repair, construction and emergency rescue. The dual-purpose vehicle for railway and highway in the prior art mainly includes: an underframe, a driver's cab, wheels and guide wheels. The driver's cab and the power unit are assembled on the upper part of the underframe, the wheels are arranged on the bottom of the underframe, and the guide wheels are installed on the bottom of the underframe through the guide mechanism. When the rail-road vehicle is running on the road, the guide wheel is retracted by the gu...
