VEHICLE DRIVE DEVICE

摘要

A vehicle drive device that includes a case forming a first accommodating space that accommodates a speed change device and a second accommodating space that accommodates a rotary electric machine; an storage that is disposed under the first accommodating space and stores oil; a hydraulic pump including a suction that suctions the oil from the oil storage; a first oil passage that supplies the oil discharged by the hydraulic pump to the speed change device as hydraulic oil; a second oil passage that supplies the oil discharged by the hydraulic pump to the rotary electric machine as cooling oil; and a third oil passage that returns the oil supplied to the rotary electric machine, from the second accommodating space to the oil storage, by allowing the oil to flow in a direction from the second accommodating space toward the first accommodating space.

1. A vehicle drive device comprising:
a case forming a first accommodating space that accommodates a speed change device and a second accommodating space that accommodates a rotary electric machine; an oil storage that is disposed under the first accommodating space and stores oil; a hydraulic pump including a suction that suctions the oil from the oil storage; a first oil passage that supplies the oil discharged by the hydraulic pump to the speed change device as hydraulic oil; a second oil passage that supplies the oil discharged by the hydraulic pump to the rotary electric machine as cooling oil; and a third oil passage that returns the oil supplied to the rotary electric machine, from the second accommodating space to the oil storage, by allowing the oil to flow in a direction from the second accommodating space toward the first accommodating space; wherein
a direction from the first accommodating space toward the second accommodating space is a target direction, and the target direction coincides with a direction toward a front of the vehicle in a state where the case is attached to the vehicle;the third oil passage includes an opening/closing mechanism that opens and closes the third oil passage, and an opening that is open toward the oil storage;the opening/closing mechanism includes an opening/closing member that is swingable about a swing axis extending in a horizontal direction orthogonal to the target direction, and that has a center of gravity below the swing axis; andthe opening/closing member is configured to swing such that the center of gravity moves in the target direction to close the opening.
