Abstract
Official abstract text for this publication.
A vehicle driving device includes a case that accommodates therein a first rotary electric machine and a second rotary electric machine arranged with rotation axes thereof parallel to each other and radially adjacent to each other, and a power control device that controls electric power supplied to the first rotary electric machine and the second rotary electric machine. In the power control device, a control board, a power card and a cooler, a reactor and a capacitor, and a water jacket are disposed in order from top in a height direction.
First claim
Opening claim text (preview).
What is claimed is: 1. A vehicle driving device comprising: a case that accommodates therein a first rotary electric machine and a second rotary electric machine arranged with rotation axes thereof parallel to each other and radially adjacent to each other; and a power control device that controls electric power supplied to the first rotary electric machine and the second rotary electric machine, wherein the power control device has a three-layer structure having an upper layer, an intermediate layer, and a lower layer in the height direction, the upper layer is provided with a control board, a power card, and a cooler, the intermediate layer is provided with a capacitor, the lower layer is provided with a reactor, and a water jacket is disposed between the intermediate layer and the lower layer. 2. The vehicle driving device according to claim 1 , wherein a terminal board holding a second connection terminal electrically connected to a first connection terminal included in the power control device is disposed beside the capacitor, and a heat shielding wall connected to the water jacket is provided between the capacitor and the second connection terminal. 3. The vehicle driving device according to claim 1 , wherein the lower layer is further provided with a DC-DC converter, and a heat shielding cover connected to the water jacket is provided between the DC-DC converter and the case. 4. The vehicle driving device according to claim 3 , wherein the reactor, the heat shielding cover, and the DC-DC converter are connected to an external surface of the water jacket that faces away from the intermediate layer. 5. The vehicle driving device according to claim 1 , wherein the reactor is connected to an external surface of the water jacket that faces away from the intermediate layer.
