Embodiment Construction

[0017] see first figure 1 , wherein a road-rail vehicle 10 is shown. The vehicle is made up of a lower part 20 and an upper part 30 , wherein the upper part 30 is pivotally connected to the lower part 20 by a turntable 40 . The upper part 30 is freely rotatable and relative to the lower part 20 at least 360°. The different components of the hydraulic system are generally placed in the lower part 20 and the upper part 30 of the vehicle 10 whereby a swivel is provided for the connection between the upper part 30 and the lower part 20 .

[0018] As shown, the vehicle 10 has two different means of transport. The lower part 20 comprises at least four wheels 22a, 22b, 22c, 22d adapted to travel on the track 50 and two tracks 24a, 24b for traveling outside the track 50 . When the vehicle 10 is to be driven on the track 50 , the vehicle 10 is in a position such that the wheels 22 a , 22 b , 22 c , 22 d are above the track 50 . The wheels 22a, 22b, 22c, 22d are then lowered onto th...

Abstract

A drive unit for a road-rail vehicle having at least four wheels, for movement on rails, wherein each wheel is driven by a separate hydraulic motor. Further the hydraulic motors driving the wheels situated on one side of a longitudinal central axis of the vehicle are connected in

Description

technical field [0001] The present invention relates to a road-rail vehicle or a two-way vehicle for carrying out construction or maintenance work along a railway. Background technique [0002] It is known that rail vehicles, road vehicles or track-road vehicles can be used to carry out construction or maintenance work along railway lines. These vehicles typically include at least four wheels for rail transport and some form of hydraulic drive. [0003] DE-A1-102005002407 describes a vehicle of this type with four wheels and at least one hydraulic motor. It also describes that the hydraulic motor connected to the wheel is connected in series to another hydraulic motor connected to the other wheel on the same side, so that the left front and rear wheels are connected together through the hydraulic motor. One disadvantage of this is that when a user moves the vehicle forward or backward during construction or maintenance work on the side of the track, the wheels may start to...
