Abstract

Apparatus for providing electrical energy, in particular for providing electrical energy from a heat flow originating from an electric motor, including a first component part, a second component part, wherein a Peltier element is arranged between the first component part and the second component part, said Peltier element being at least partially surrounded by a layer of insulation provided between the first component part and the second component part, with the result that the Peltier element forms a thermal bridge between the first and the second component parts, and wherein the first and the second component parts are selected from the following group: gear mechanism, motor and adapter plate.

First claim

The invention claimed is:

1. Apparatus for providing electrical energy, in particular for providing electrical energy from a heat flow originating from an electric motor, comprising
a first component part,
a second component part,
wherein a Peltier element is arranged between the first component part and the second component part, said Peltier element being at least partially surrounded by a layer of insulation provided between the first component part and the second component part, such that the Peltier element forms a thermal bridge between the first and the second component parts, and
wherein the first and the second component parts are selected from the following group: gear mechanism, motor ( 16 ) and adapter plate.

2. Apparatus according to claim 1 , wherein the first and the second component parts are different.

3. Apparatus according to claim 1 , wherein the second component part is an adapter plate arranged between a motor and a gear mechanism.

4. Apparatus according to claim 1 , wherein the layer of insulation has a material with a lower thermal conductivity than the material of at least one of a housing of the first component part and a housing of the second component part.

5. Apparatus according to claim 1 , wherein the layer of insulation has a thermal conductivity of at most 25 W/(m*K).

6. Apparatus according to claim 1 , wherein supports and/or spacer sleeves are provided between the first component part and the second component part.

7. Apparatus according to claim 1 , wherein a heat-conducting film and/or a layer of heat-conducting paste is provided in each case between the first component part and/or the second component part, on the one hand, and the Peltier element, on the other hand.

8. Apparatus according to claim 1 , wherein the layer of insulation comprises cavities.

9. Apparatus according to claim 1 , further comprising an energy store connected to the Peltier element.

10. System for detecting at least one measured variable of a gear mechanism comprising an apparatus according to claim 1 and at least one sensor for detecting the at least one measured variable, wherein the sensor is connected to the Peltier element for the purpose of supplying energy to the sensor.
