Industrial truck with a drive unit which is fastened to a neighboring frame segment of a vehicle frame
An industrial truck, in particular a fork lift truck, is provided with a rear weight and an internal combustion engine. The internal combustion engine is fastened to the rear weight. The internal combustion engine is advantageously mounted so that it can oscillate around an axis that extends in the transverse direction of the industrial truck.
1. An industrial truck, comprising:
a drive unit having an internal combustion engine having an end;
at least one unit driven by the engine and located on the end, wherein the unit is fastened to a neighboring frame segment of a vehicle frame; and
a plurality of bearings located inside an axial extension of the drive unit including a first bearing and a second bearing, wherein the second bearing is at a spaced distance in an axial direction from the first bearing, wherein the first and second bearings are located diagonally below a center of gravity of the drive unit, and wherein a third bearing is located diagonally above the center of gravity.
2. The industrial truck as claimed in claim 1 , wherein the first and the second bearings are located in a common plane.
3. The industrial truck as claimed in claim 2 , wherein the second bearing is in the vicinity of an intermediate flange of the drive unit located axially between the internal combustion engine and the at least one unit.
4. An industrial truck as claimed in claim 2 , wherein the industrial truck is a fork-lift truck with a rear-end counterweight, wherein the drive unit is oriented transverse to a longitudinal axis of the truck, and the counterweight is provided as a frame segment for the mounting of the drive unit.
5. The industrial truck as claimed in claim 2 , wherein the plane is located below the drive unit.
6. The industrial truck as claimed in claim 1 , wherein the second bearing is in the vicinity of an intermediate flange of the drive unit located axially between the internal combustion engine and the at least one unit.
7. An industrial truck as claimed in claim 6 , wherein the industrial truck is a fork-lift truck with a rear-end counterweight, wherein the drive unit is oriented transverse to a longitudinal axis of the truck, and the counterweight is provided as a frame segment for the mounting of the drive unit.
8. An industrial truck as claimed in claim 1 , wherein the industrial truck is a fork-lift truck with a rear-end counterweight, wherein the drive unit is oriented transverse to a longitudinal axis of the truck, and the counterweight is provided as a frame segment for the mounting of the drive unit.
9. The industrial truck as claimed in claim 1 , including an exhaust system connected to the internal combustion engine and fastened to the counterweight, including an isolating element that equalizes movements of the internal combustion engine integrated into the exhaust system, and wherein the bearings are arranged so that the movements of the drive unit relative to the counterweight excited by bumps in the floor or road occur around a center of motion which is located in the vicinity of the isolating element or next to it.
10. The industrial truck as claimed in claim 1 , wherein the unit is a hydraulic pump.
11. An industrial truck, comprising:
a drive unit having an internal combustion engine having an end;
at least one unit driven by the engine and located on the end, wherein the unit is fastened to a neighboring frame segment of a vehicle frame; and
a plurality of bearings located inside an axial extension of the drive unit including a first bearing, a second bearing, and a third bearing, wherein the first bearing is located diagonally below a center of gravity of the drive unit in a direction of the frame segment, wherein the third bearing is at a spaced distance in an axial direction from the second bearing, and wherein the second and third bearings are located diagonally above the center of gravity.
12. The industrial truck as claimed in claim 11 , wherein the second and the third bearings are located in a common plane.
13. An industrial truck as claimed in claim 12 , wherein the industrial truck is a fork-lift truck with a rear-end counterweight, wherein the drive unit is oriented transverse to a longitudinal axis of the truck, and the counterweight is provided as a frame segment for the mounting of the drive unit.
14. An industrial truck as claimed in claim 11 , wherein the industrial truck is a fork-lift track with a rear-end counterweight, wherein the drive unit is oriented transverse to a longitudinal axis of the truck, and the counterweight is provided as a frame segment for the mounting of the drive unit.
15. The industrial truck as claimed in claim 11 , including an exhaust system connected to the internal combustion engine and fastened to the counterweight, including an isolating element that equalizes movements of the internal combustion engine integrated into the exhaust system, and wherein the bearings are arranged so that the movements of the drive unit relative to the counterweight excited by bumps in at least one of a floor or road occur around center of motion which is located in the vicinity of the isolating element or next to it.
16. The industrial truck as claimed in claim 11 , wherein the unit is a hydraulic pump.
