Arrangement of a motor on a support winch
An arrangement of a motor on twin landing gears is described. The landing gears are interconnected via a connecting shaft and can be telescoped by starting up the motor. To minimize damage to the motor and at the same time to ensure cost-effective production, it is provided that the motor with its driveshaft engages with the connecting shaft and is supported on a component that is fixed relative to the motor.
1. An apparatus, comprising: arrangement of a motor on twin landing gears on a semi-trailer of a tractor-trailer, wherein the landing gears are interconnected via a connecting shaft and can be telescoped by starting up the motor, wherein a driveshaft of the motor directly engages with the connecting shaft and the motor is supported on a component that is fixed relative to the motor, and wherein a spring element is arranged between the motor and the fixed component.
2. An apparatus as claimed in claim 1 , wherein the spring element comprises a spiral spring, a torsion element or a shock absorber.
3. An apparatus as claimed in claim 2 , wherein the torsion element comprises an elastic hose.
4. An apparatus as claimed in claim 3 , wherein the connecting shaft is arranged within the spiral spring or the torsion element without contacting the spiral spring or torsion element.
5. An apparatus as claimed in claim 1 , wherein the fixed component is at least one of the two landing gears.
6. An apparatus as claimed in claim 5 , wherein a spiral spring or a torsion element is non-rotatably mounted to at least one of the landing gears and to the motor.
7. An apparatus as claimed in claim 5 , wherein a spiral spring or a torsion element at least partially surrounds the connecting shaft.
8. An apparatus as claimed in claim 1 , wherein the connecting shaft is fixed to and is adapted to co-rotate with the driveshaft.
9. An apparatus as claimed in claim 1 , wherein the driveshaft is configured as a hollow shaft.
10. An apparatus as claimed in claim 9 , wherein the hollow shaft has a circular cross section.
11. An apparatus as claimed in claim 1 , wherein (a) the motor is not self-locking, (b) the motor comprises an electric motor, or (c) the motor is designed for a torque of 5 to 15 Nm, or combinations thereof.
12. An apparatus, comprising: arrangement of a motor on twin landing gears on a semi-trailer of a tractor-trailer, wherein the landing gears are interconnected via a connecting shaft and can be telescoped by starting up the motor, wherein a driveshaft of the motor directly engages with the connecting shaft and the motor is supported on a component that is fixed relative to the motor, wherein a spring element is arranged between the motor and the fixed component, and wherein the motor is located between the landing gears.
13. An apparatus as claimed in claim 12 , wherein the spring element comprises a spiral spring, a torsion element or a shock absorber.
14. An apparatus as claimed in claim 13 , wherein the torsion element comprises an elastic hose.
15. An apparatus as claimed in claim 14 , wherein the connecting shaft is arranged within the spiral spring or the torsion element without contacting the spiral spring or torsion element.
16. An apparatus as claimed in claim 12 , wherein the fixed component is at least one of the two landing gears.
17. An apparatus as claimed in claim 16 , wherein a spiral spring or a torsion element is non-rotatably mounted to at least one of the landing gears and to the motor or wherein a spiral spring or a torsion element at least partially surrounds the connecting shaft.
18. An apparatus as claimed in claim 12 , wherein the connecting shaft is fixed to and is adapted to co-rotate with the driveshaft.
