Bus with idler gear mechanism

Abstract

The invention provides a bus with an idler gear mechanism, comprising a power car and a tractor, wherein the power car and the tractor are connected through an articulated shaft; first track wheel mechanisms are arranged at the bottom of the power car and the tractor, and two sets of second track wheel mechanisms are arranged between the two sets of the first track wheel mechanisms; and the frontand rear frames are adopted and the hydraulic steering system is cooperated to realize flexible steering on the highway. The bus with an idler gear mechanism has the advantages that: the bus with an idler gear mechanism can ensure that no traveling resistance will be generated during the turning process of the high-speed railway car, and allows for smaller corners; the first track wheel mechanismsand the second track wheel mechanisms are respectively arranged at the bottom of the power car and the tractor; and the second track wheel mechanisms are positioned between the first track wheel mechanisms, thereby reducing the span distance between the track wheels, and making the highway car more stable and safe in the turning process.

Description

technical field [0001] The invention relates to a dual-purpose vehicle for railway and highway, in particular to a road-rail vehicle with an idler mechanism. Background technique [0002] At present, dual-purpose vehicles for railway and road are widely used in the rail transportation industry because they can run on both roads and railways. Dual-purpose vehicles for railway and road are usually used for railway traction, emergency repair, construction and emergency rescue operations. . Because the quality of rail transport vehicles such as trains is generally large, the existing public and railway vehicles are generally relatively large in order to provide greater traction, but the volume is relatively large. If it is small, it will produce greater resistance or even rollover, which poses a greater safety hazard. Those skilled in the art propose to adopt the structure that the front and rear parts of the vehicle frame of the existing loader cooperate to reduce the turning...

Problems solved by technology

Because the mass of rail transport vehicles such as trains is generally large, the existing public and railway vehicles are generally relatively large in order to provide greater traction, but the volume is relatively large. Small but will produce greater resistance or even rollover, and there is a greater potential safety hazard

Those skilled in the art propose to adopt the structure that the front and rear parts of the vehicle frame of the existing loader cooperate to reduce the turning radius of the road-rail car, but the steering system of the existing loader consists of two ends of the steering hydraulic cylinder respectively connected to the front vehicle frame, The rear frame is hinged, the rear frame and the front frame are connected by a hinge point, and the two can rotate around the hinge point to realize the turning function, but when this structure is used on a public rail car, the front frame, rear frame The angle of the steering wheel is locked and cannot change with the direction of the rail
