  • Patent number: 11833904
    Abstract: A first inner support member that supports a first friction member of a first engagement device from an inner side in a radial direction includes a tubular support portion having a tubular shape extending along an axial direction and supporting the first friction member, and a radially extending support portion provided to extend to the inner side in the radial direction from the tubular support portion. The radially extending support portion is connected to the input member such that the input member and the first inner support member rotate integrally, and a first bearing that rotatably supports a rotor support member is disposed on a first side in the axial direction with respect to a rotor and is disposed on an outer side in the radial direction with respect to the tubular support portion.
    Type: Grant

  • Publication number: 20220242216
    Abstract: A rotor support member includes: a tubular portion having a tubular shape extending along an axial direction and supporting a rotor of a rotary electric machine; and a flange portion provided to extend along a radial direction on an inner side in radial direction with respect to tubular portion at a position adjacent to a first engagement device on a first side in the axial direction, and connected to tubular portion. The flange portion includes a cylinder forming portion protruding to first side in the axial direction so as to form a cylinder portion on which a first piston portion of the first engagement device slides. A rotation sensor includes a rotating body supported by an outer peripheral surface of cylinder forming portion on an outer side in the radial direction, and a fixed body disposed on the outer side in the radial direction with respect to the rotating body.

  • Patent number: 11254200
    Abstract: A vehicle drive device includes: rotary electric machine; rotor support member; friction engagement device disposed at position on inner side in radial direction with respect to a rotor and at which friction engagement device overlaps rotor as viewed in radial direction along radial direction; and a first and second bearing that rotatably support rotor support member. Friction engagement device has a first and second engagement device disposed side by side in axial direction. First piston portion of first engagement device and a second piston portion of second engagement device are disposed separately on both sides in axial direction across a first and a second friction member. First bearing is disposed at a position at which first bearing overlaps first piston portion as viewed in the radial direction. Second bearing is disposed at a position at which second bearing overlaps second piston portion as viewed in the radial direction.

  • Patent number: 8394001
    Abstract: A control device controlling a vehicle's automatic transmission. The automatic transmission engages first and second friction engagement elements by fluid pressure from a pump operating using motive power from the vehicle's motor when a shift position is at a reverse traveling position, places the first friction engagement element on standby at a predetermined pressure that is higher than a stroke starting pressure by which a piston stroke is started and lower than a complete engagement pressure or engages the first friction engagement at the complete engagement pressure when the shift position is at a non-traveling position, and engages a third friction engagement element as a starting shift speed when the shift position is at a forward traveling position.
