Embodiment 1
[0022] The guiding device of the present invention is mainly composed of a single-axis bogie (or called a guiding bridge), a suspension system, a lifting mechanism, a two-way acting cylinder type shock absorber and the like. A road and railway dual-purpose vehicle needs to be equipped with a guiding device of the present invention behind the steering axle and the driving axle. When driving on the road, the lifting mechanism of the guiding device is used to lift the guiding bridge away from the ground, and the driving state is the same as that of an ordinary road vehicle. . When the railway is running, the guide bridge is put down, the steering bridge of the vehicle is withdrawn and left from the ground, and the vehicle is supported and driven on the rail by the front and rear guide bridges and the vehicle driving axle together. At this time, the driving direction of the vehicle is controlled by the front and rear guide axles, while the driving force and braking force of the ve...
Embodiment 2
[0032]This example is basically the same as Embodiment 1, except that the hydraulic cylinder used in the lifting mechanism 7' is lifted. When the oil cylinder lifts the single-axis bogie 4', the air spring air bag of the guide mechanism suspension 5' is deflated; when the guide mechanism suspension When the 5' air spring air bag is inflated, the 7' oil cylinder of the lifting mechanism is recovered, realizing the change of driving on roads and railways.
Embodiment 3
[0034] This example is an embodiment of the guide device for road and rail dual-purpose vehicles using hydraulic suspension, and its hydraulic cylinder has both bearing and lifting functions. The drive axle suspension 3″ and the guide mechanism suspension 5″ are both hydraulic suspensions. At the same time, the separate lifting mechanism is cancelled. The movement of the hydraulic device of the guide mechanism suspension 5″ drives the single-axis bogie to realize the vehicle road / Transformation of rail travel.
[0035] Same as Embodiment 1, in this embodiment, the hydraulic cylinders of the drive axle suspension 3″ and the guide mechanism suspension 5″ are directly connected, and the hydraulic pressures of the two suspensions are always equal. Proportionally distribute the load to realize the vehicle's requirements for the distribution of adhesion.
