Work machine

Abstract

A work machine, more particularly a wheeled loader, having a cab for the operator of the work machine, wherein the work machine has a drive which can be operated with hydrogen and that one or more tanks for receiving hydrogen are provided, wherein components for receiving the tanks are provided, wherein the tank or tanks are arranged below the cab and, when the work machine is viewed from above, next to the cab of the work machine, wherein the components for receiving the tanks do not have a direct mechanical connection to the cab, and that an armor is provided which partially or completely surrounds the tank.

Claims

1. A work machine comprising: a front chassis section and a rear chassis section which are connected to one another in an articulated manner; a cab for an operator of the work machine; one or more hydrogen tanks; an armor which at least partially surrounds each tank of the one or more hydrogen tanks; and a drive which can be operated with hydrogen, wherein the one or more hydrogen tanks are located on the rear chassis section and are arranged below the cab on at least a first side.

2. The work machine according to claim 1, wherein the work machine has two or more axles, and that at least one tank of the one or more hydrogen tanks is arranged in an articulation region, between the two or more axles.

3. The work machine according to claim 1, wherein the work machine has a frame and the armor is arranged outside of the frame.

4. The work machine according to claim 1, wherein on both sides of the work machine, at least one tank of the one or more hydrogen tanks having the armor is arranged.

5. The work machine according to claim 1, wherein the one or more hydrogen tanks are suitable for storing hydrogen in liquid and/or gaseous form and/or in bonded form.

6. The work machine according to claim 1, wherein the work machine has steps for accessing the cab and the steps are located in a rear region of the work machine.

7. The work machine according to claim 1, further comprising an internal combustion engine for the combustion of hydrogen.

8. The work machine according to claim 1, further comprising a fuel cell for generating electrical energy by means of hydrogen.

9. The work machine according to claim 1, wherein at least one tank of the one or more hydrogen tanks has an elongate form.

10. The work machine according to claim 1, wherein the one or more hydrogen tanks are not fixedly connected to the work machine and are replaceable.

11. The work machine according to claim 1, wherein there are at least two hydrogen tanks.

Description

BRIEF DESCRIPTION OF THE FIGURES

(1) The figures are drawn approximately to scale, although other relative dimensions may be used.

(2) FIG. 1 shows a schematic side view of a wheeled loader from the right,

(3) FIG. 2 shows a schematic side view of a wheeled loader from the left,

(4) FIG. 3 shows a schematic top view of the wheeled loader,

(5) FIG. 4 shows a schematic view of a wheeled loader from below and

(6) FIG. 5 shows a schematic view of the wheeled loader from the left with the means of access moved to the rear.

DETAILED DESCRIPTION

(7) FIGS. 1 and 2 show side views of a wheeled loader 1 according to an embodiment.

(8) The wheeled loader has a front chassis section 2 and a rear chassis section 3, which are connected to one another in an articulated manner.

(9) Reference sign 4 denotes the cab for the operator of the wheeled loader.

(10) The wheeled loader furthermore has a front axle and a rear axle, both of which are denoted by reference sign 7.

(11) As can be seen from FIGS. 1 and 2, there is a hydrogen tank 5 located on each side of the wheeled loader, in each case surrounded by an armor 6. The wheeled loader has components for receiving the tanks, where the components for receiving the tanks do not have a direct mechanical connection to the cab.

(12) The tank 5 and the armor 6 are, on both sides of the wheeled loader, located on the rear chassis section 3 in a region under the cab 4 and between the two axles 7.

(13) From the top view according to FIG. 3 and the illustration from below according to FIG. 4, it is discernible that the two tanks 5 with the respective armor 6 are arranged next to the cab 4, i.e. arranged offset to the side relative to the cab 4.

(14) The armor 6 in each case surrounds of the tanks 5 completely, i.e. on all sides.

(15) FIG. 5 shows an embodiment which corresponds to the embodiment of FIGS. 1 and 2 but with the difference that the stairs or other means of access 8 for the machine operator is arranged in the rear region, i.e. behind the rear axle 7.

(16) After accessing, the machine operator walks forward to the cab 4 over the rear wheel house or body parts.
