摘要:
A mounting structure for a drive device (2) includes: a power generation unit (3) having an engine (6) and a generator (7) driven by the engine to generate electric power; and a drive unit (4) having a motor (13) for traveling and a power transmission mechanism (15) that outputs torque from the motor toward a driving wheel (14). A frame member of a vehicle body is provided inside an engine compartment (5). The power generation unit and the drive unit are arranged, inside the engine compartment, side by side in a width direction of a vehicle so as not to contact each other, and are each connected to the frame member via a mount member (M1, M2, M3, M4, M5). Portions of the power generation unit and the drive unit, which are close to each other in the width direction, are connected by a connecting member (M6) having an anti-vibration elastic body (32).
摘要:
An electric motor includes a rotor shaft, and the rotor shaft has a shaft-core oil passage and radial oil passages. The shaft-core oil passage includes an inner wall facing radially inward. The radial oil passages are provided toward a radial outer side of the rotor shaft from the shaft-core oil passage. The radial oil passages penetrate through the rotor shaft. The radial oil passages have corresponding one of first connection openings connected to the shaft-core oil passage, so that oil that is not discharged from the first connection openings to the radial oil passage is supplied to other supply destinations. A distance of the first connection openings from the shaft core is shorter than a distance, from the shaft core, of that part of the inner wall which is not provided with the first connection openings.
