Abstract

The present disclosure relates to a boat drive for driving a boat, comprising a drive unit comprising an electric motor and a mounting connected to the drive unit for connecting the boat drive to the boat, wherein the mounting is provided for distancing the drive unit from a hull of the boat, wherein a decoupling arrangement for decoupling of oscillations (S) generated in the drive unit is arranged between the drive unit and the mounting.

First claim

The invention claimed is:

1. A boat drive for driving a boat, comprising:
a drive unit comprising an electric motor;
a mounting connected to the drive unit for connecting the drive unit to the boat, wherein the mounting is provided for distancing the drive unit from a hull of the boat;
a clamping device on an end of the mounting having at least one clamping arm that is configured to clamp around an exterior of the drive unit to connect the drive unit to the mounting; and
a decoupling arrangement positioned between the drive unit and the clamping arm of the mounting such that the decoupling arrangement is configured to decouple oscillations generated in the drive unit from the mounting.

2. The boat drive according to claim 1 , wherein the decoupling arrangement comprises at least one oscillation decoupling damping element which is arranged between the drive unit and the mounting.

3. The boat drive according to claim 2 , wherein the at least one oscillation decoupling damping element comprises a resilient material.

4. The boat drive according to claim 3 , wherein the resilient material is an elastomeric material.

5. The boat drive according to claim 3 , wherein the resilient material is rubber.

6. The boat drive according to claim 2 , wherein the at least one oscillation decoupling damping element comprises at least two materials with differing resilience.

7. The boat drive according to claim 6 , wherein the at least two materials are at least two resilient materials.

8. The boat drive according to claim 2 , wherein the at least one oscillation decoupling damping element is configured as a substantially continuous intermediate layer.

9. The boat drive according to claim 1 , wherein the clamping device is configured as a sleeve, clamp or clip.

10. The boat drive according to claim 1 , wherein the mounting comprises a flange for connection to a fastening region of the drive unit, wherein the flange, the fastening region and the decoupling arrangement are arranged between the flange and the fastening region.

11. The boat drive according to claim 1 , further comprising a position securing unit for securing the position of the drive unit relative to the mounting.

12. The boat drive according to claim 11 , wherein the position securing unit is designed to counter at least one of rotation or displacement of the drive unit relative to the mounting.

13. The boat drive according to claim 1 , further comprising a damping adjustment device for adjusting a damper hardness of the decoupling arrangement.

14. The boat drive according to claim 13 , wherein at least one oscillation sensor senses at least one of an oscillation of the drive unit or the mounting.

15. The boat drive according to claim 14 , wherein the damping adjustment device adjusts the damper hardness on a basis of values obtained by the at least one oscillation sensor.

16. The boat drive according to claim 1 , further comprising one or more rod segments positioned in the decoupling arrangement, the one or more rod segments being configured to extend parallel to a longitudinal axis of the drive unit to secure the drive unit relative to the mounting to counter rotation of the drive unit relative to the mounting.

17. The boat drive according to claim 1 , wherein an internal surface of the clamping arm and an outer surface of the drive unit have a non-round cross-sectional contour to secure the drive unit relative to the mounting to counter rotation of the drive unit relative to the mounting.

18. A boat drive comprising:
a drive unit comprising an electric motor;
a mounting engaging the drive unit for engaging the drive unit to a boat, wherein the mounting distances the drive unit from a hull of the boat,
a clamping device on an end of the mounting having at least one clamping arm that is configured to clamp around an exterior of the drive unit to connect the drive unit to the mounting; and
a decoupling arrangement arranged between the drive unit and the clamping arm of the mounting, the decoupling arrangement having at least one oscillation decoupling damping element comprising a resilient material;
wherein the decoupling arrangement decouples oscillations generated in the drive unit.

19. The boat drive according to claim 18 , wherein the at least one oscillation decoupling damping element comprises at least two materials with different resiliencies.
