- the reactor L.1 is molded with an insulating resin in the configuration shown in FIG. 10, and the upper end of this mold part is a flange shape that also serves as the lid of the oil chamber 2 16. The point to do is different.
- This blister-shaped lid made of fi-resin is provided with a terminal for connecting the reactor to the bus bar, not shown.
- the other portions are the same as those in FIG. 10, and the description will not be repeated. By doing so, the assembly of the reactor L 1 becomes easy and the number of parts can be reduced. ' ⁇ '
- a driving device integrated with the boost converter and the inverter can be realized. And even if it integrates, the heat generation of the booster's rear tutor can be dissipated well, and a reduction in efficiency of the boost converter can be avoided. .
- FIG. 17 is a diagram showing a cross section of the vehicle drive apparatus in the second embodiment.
- reactor L 1 A is arranged in the oil pan below motor generator MG 2.
- the lubricating oil pumped up by the differential gear DEF and the reduction gear RG is dripped onto the reactor L 1 A as indicated by arrows F 19 and F 20.
- An oil path is provided in the partition wall 200. As a result, the heat generated in the reactor L 1 A is dissipated through the lubricating oil.
- Capacitor C 2 interferes with reactor L 1 A, and bulkhead 2 0 0
- the capacitor may be moved to the part where the rear titlel has been placed in the first embodiment.
- a capacitor C 2 A can be arranged instead of the capacitor C 2.
- the drive integrated with the boost converter and the inverter is also provided.
- a moving device can be realized. And even if it integrates, the heat of the reactor of the boost converter can be dissipated well, and the efficiency of the boost converter can be avoided from being lowered.
- FIG. 18 is a diagram for explaining a modification of the portion for circulating the lubricating oil.
- the configuration shown in Fig. 18 is the same as the configuration shown in the first embodiment. Instead of the configuration where the oil is pumped with a gear ⁇ , the lubricating oil is pumped from the oil reservoir and supplied to cool the reactor L1. An oil pump is provided.
- a trochoid type oil 10 "pump 4 0 0 is installed and the lubricating oil is pumped up from the oil reservoir at the bottom of the case to the oil passage ⁇ 0 4
- the outlet of the oil passage 4 0 7 is located upstream of the power control unit including the substrate 1 2 0 in the lubricating oil lubrication path.
- the oil pump 4 0 0 includes a drive gear 40 2 that meshes with the differential gear DEF, an inner rotor 4 0 4 that rotates together with the shaft of the drive gear 4 0 2, and 15 an inner rotor 4 0 4 And an outer rotor 4 0 6 in which the teeth mate.
- the outlet of the oil passage 4 0 7 communicates with the oil passage 2 1 0 and the oil chamber 2 1 6 for guiding the cooling lubricating oil to the reactor L 1.
- the lubricating oil flowing into the oil chamber 2 1 6 from the oil passage 2 1 0 cools the reactor L and flows as shown by the arrows F 1, F 2, F 3, F 4 and decelerates from the oil drain hole 2 1 4 Return to gear RG side.
