DESCRIPTION OF THE INVENTION

[0031] FIG. 1 is a view in perspective of a remotely controlled mobile machine 1 according to the invention, for example a forestry machine.

[0032] The mobile machine 1 comprises a chassis 2, which in the illustrated embodiment is formed by two tracks 2a, 2b, each of which is driven by a hydraulic traction drive motor, for example.

[0033] As the drive source, the mobile machine 1—as shown in FIGS. 3 and 4—has a drive unit M which is located inside the forward section of a hood-like or shaped housing 4. The machine 1 does not have a driver workplace for an operator and can be operated remotely by an operator by means of a remote control which is not illustrated in any further detail.

[0034] In the illustrated embodiment, the machine 1 also has a rope winch 5, a stanchion 6 and an adjustable ramp plate 7, which is located on the rear of a vehicle body 9 of the machine 1 so that it can be adjusted around a horizontal transverse vehicle axis 8.

[0035] The stanchion 6 is located in the vertical direction above a base plate 10 of the vehicle body 9.

[0036] The hood-like housing 4 in which the drive unit M and the rope winch 5 are located forms a forward half of the machine 1. The base plate 10 with the stanchion 6 on it forms a rear half of the machine 1. The drive unit M is located in a forward section of the hood-like housing 4 and the rope winch 5 in a rear section of the hood-like housing 4.

[0037] The drive unit M—as is visible in FIGS. 3 and 4—has an internal combustion engine 15 and at least one hydraulic pump 16, 17 driven by the internal combustion engine 15, which hydraulic pump supplies a hydraulic system of the machine with pressure medium. The internal combustion engine 15—as shown in FIGS. 3 and 4—is oriented with a longitudinal axis in the transverse direction of the vehicle and drives the at least one hydraulic pump 16, 17, for example a variable displacement pump, which supplies the hydraulic system of the machine 1 with pressure medium. As consumers, the hydraulic system comprises the traction drive motors, a hydraulic motor that drives the rope winch 5 and additional hydraulic consumers, for example hydraulic cylinders for adjusting the ramp plate 7.

[0038] The internal combustion engine 15 and the hydraulic pumps 16, 17 and thus the drive unit M are located in a closed engine compartment 20 located inside the hood-like housing 4. The engine compartment 20 is bounded on the sides by sheet metal side walls 21, 22, on the bottom by the base plate 10 and on the top by the cover plate 23. The sheet metal side wall 22 thereby forms a lateral exterior wall of the hood-like housing 4. The cover plate 23 is bent at a right angle and, in the vicinity of the internal combustion engine 15, has a section that is higher than in the vicinity of the hydraulic pumps 16, 17. In the longitudinal direction of the vehicle, toward the rear and front, the engine compartment 20 is bounded by a front wall and a rear wall. The engine compartment 20 is preferably provided with insulation (thermal insulation and acoustic insulation).

[0039] In the vertical direction, above the engine compartment 20 in which the internal combustion engine 15 and the hydraulic pumps 16 and 17 are located, in the hood-like housing 4 there is a radiator and exhaust gas space 30 in which are a first radiator device 31, a second radiator device 32 and an exhaust system with a muffler 33 of the internal combustion engine 15. In the illustrated exemplary embodiment, the first radiator device 31 is a radiator device of the internal combustion engine 15 and the second radiator device 32 is a radiator device, for example a hydraulic fluid cooler, of the hydraulic system. It goes without saying that the radiator devices 31, 32 can also have interchanged functions, so that the first radiator device 31 is in the form of a radiator device, for example a hydraulic fluid radiator, of the hydraulic system and the second radiator device 32 is in the form of a radiator device for the internal combustion engine 15.

[0040] The radiator device 31 and/or the radiator device 32 can be provided with a driven fan which generates a cooling airflow. The radiator and exhaust gas space 30 is bounded on the side by the sheet metal side walls 21, 22 and on the bottom by the cover plate 23 of the engine compartment 20. The radiator and exhaust gas space 45 is essentially open on top and is provided with an air exhaust grate 35.

[0041] The radiator device 31 of the internal combustion engine 15 and/or the radiator device 32 of the hydraulic system are preferably oriented horizontally and have an air outlet that directs a cooling airflow vertically upward. The radiator device 31 of the internal combustion engine 15 and/or the radiator device 32 of the hydraulic system therefore make it possible to discharge air and heat upward. The radiator device 31 of the internal combustion engine 15 is located on the elevated section of the cover plate 23 above the internal combustion engine 15 and the radiator device 32 is located on the lower section of the cover plate 23 above the hydraulic pumps 16, 17.

[0042] The muffler 33 is also located on the lower section of the cover plate 23 above the hydraulic pumps 16, 17. The muffler 33 is also located in a noise reduction enclosure 40 located in the radiator and exhaust gas space 30.

[0043] FIG. 2 is an overhead view of the radiator and exhaust gas space 30 located above the engine compartment with the air outlet grate 35 removed, showing the muffler 33, the radiator device 32 of the hydraulic system and the radiator device 31 of the internal combustion engine 15. As shown in FIG. 2, the radiator device 31 of the internal combustion engine 15 and the radiator device 32 of the hydraulic system are located next to each other in the transverse direction of the vehicle and the muffler 33 is located forward of the radiator device 32 in the longitudinal direction of the vehicle.

[0044] According to the invention—as is visible in FIGS. 2 to 4—located inside the hood-like housing 4 is at least one storage compartment 50 or 51 that can be heated by the waste heat of the drive unit M. In the illustrated exemplary embodiment there are two storage compartments 50, 51, wherein inside the hood-like housing 4 there is a first storage compartment 50 that can be heated by the waste heat of at least one hot component of the drive unit M and inside the hood-like housing 4 there is at least one second storage compartment 51 that can be heated by the waste heat of at least one warm component of the drive unit M.

[0045] In the illustrated exemplary embodiment, the hot component of the drive unit M that heats the first storage compartment 50 is formed by the muffler 33. Alternatively, the hot component of the drive unit M that heats the first storage compartment 50 can be formed by a manifold 80 of the exhaust system of the internal combustion engine 15. In the illustrated exemplary embodiment, the warm component of the drive unit M that warms the second storage compartment 51 is formed by the radiator device 32. Alternatively, the warm component of the drive unit M that warms the second storage compartment 51 can be formed by the radiator device 31 or by one or both hydraulic pumps 16 and 17 or hoses or pipes connected to the hydraulic pump 16 or 17.

[0046] According to the invention, therefore, located inside the hood-like housing 4—as shown in FIGS. 2 and 3—near or adjacent to the hot component of the drive unit M, in the illustrated exemplary embodiment near or adjacent to the muffler 33, is the first storage compartment 50 that can be heated by the waste heat of the hot component of the drive unit M. The first storage compartment 50 is therefore designed as a hot compartment, which is provided for carrying, warming and keeping hot foods and beverages, in particular tea or coffee, hot.

[0047] According to the invention, therefore, located inside the hood-like housing 4—as shown in FIGS. 2 and 4—near or adjacent to the warm component of the drive unit M, in the illustrated exemplary embodiment near or adjacent to the radiator device 32, is the second storage compartment 51 that can be warmed by the waste heat of the warm component of the drive unit M. The second compartment 51 is therefore designed as a warming compartment, which is provided for carrying, heating and keeping articles of clothing, for example gloves, warm.

[0048] The first storage compartment 50 is hereby located in the radiator and exhaust gas space 30 near or adjacent to the muffler 33.

[0049] The second storage compartment 51 is accordingly located in the cooling and exhaust gas space 30 near or adjacent to the radiator device 32.

[0050] The first storage compartment 50 is bounded on the outside by the sheet metal side wall 22 and on the inside by a vertical sheet metal partition 55 and a side wall 41 of the noise reduction enclosure 40. The first storage compartment 50 extends toward the front in the longitudinal direction of the vehicle to the forward wall 60 of the hood-like housing 4 and toward the rear to a rear wall 61. The first storage compartment 50 is located to the side of and vertically above the muffler 33 and in the lateral area next to the muffler 33 extends to the cover plate 23. The thermal transport from the hot component, in the illustrated exemplary embodiment from the muffler 33, to the first storage compartment 50 preferably takes place via radiation from the hot component and/or via the mass transport of hot air and/or by thermal conduction via the supporting components that hold the hot component in place, which can be made of metal or aluminum.

[0051] The second storage compartment 51 is bounded on the outside by the sheet metal side wall 22 and on the inside by a side wall 56 which lies in the exhaust flow of the radiator device 32. In the illustrated embodiment, the side wall 56 extends diagonally downward and is connected at its lower end to the sheet metal side wall 22. The second storage compartment 51 extends forward in the longitudinal direction of the vehicle to the back wall 61 of the first storage compartment 50 and to the rear to a rear wall 63. The second storage compartment is located to the side of and vertically above the radiator device 32 and extends in the transverse direction of the vehicle from the sheet metal side wall 22 over approximately one-half of the surface area of the radiator device 32. The thermal transport from the warm component, in the illustrated exemplary embodiment from the radiator device 32, to the second storage compartment 51 preferably takes place via radiation from the warm component and/or via the mass transport of warm air and/or by thermal conduction via the supporting components that fasten the warm component in place, which can be made of metal or aluminum.

[0052] The first storage compartment 50—as shown in FIG. 1—is accessible by means of a cover 70 located in a top wall of the hood-like housing 4.

[0053] The second storage compartment 51—as shown in FIG. 1—is accessible by means of a cover 71 located in the top wall of the hood-like housing 4.

[0054] The cover 70 and the cover 71 are thereby located next to the air outlet grate 35 in the transverse direction of the vehicle.

[0055] The first storage compartment 50 is therefore in the form of a storage compartment enclosed by the walls 22, 41, 55, 60, 61, 23 and the cover 70.

[0056] The second storage compartment 51 is therefore in the form of a storage compartment enclosed by the walls 22, 56, 61, 63 and the cover 71.
