  • Publication number: 20240229923
    Abstract: A blade portion that rotates integrally with a target shaft portion is provided between a target outer peripheral surface that is an outer peripheral surface of the target shaft portion and a tubular inner peripheral surface of a case. A first opening that communicates with a first oil passage is located away, on a first axial side, from a second opening that communicates with a second oil passage. The first oil passage communicates with an oil reservoir. The second oil passage communicates with a target space to which oil is supplied. Assuming that a forward rotation state is a rotation state of each part when a wheel is rotating in a direction in which a vehicle moves forward, the blade portion force-feeds the oil to a second axial side when the target shaft portion is in the forward rotation state.

  • Publication number: 20240235316
    Abstract: A case (1) that houses a rotary electric machine (2) and an inverter device (INV) has an inlet (11) through which coolant flows, and a channel (4) along which the coolant flows. The channel (4) includes a first heat exchange portion (41) where heat is exchanged between the inverter device (INV) and the coolant, and a turbine disposition portion (43) where a turbine (7) is disposed. The turbine (7) is rotated by a flow of the coolant passing through the turbine disposition portion (43), and a pump rotor (88) of an oil pump (8) that discharges oil to be supplied to the rotary electric machine (2) is drivingly connected to the turbine (7).

  • Patent number: 7871474
    Abstract: A method for manufacturing bodies formed from insulated soft magnetic metal powder by forming an insulating film of an inorganic substance on the surface of particles of a soft magnetic metal powder, compacting and molding the powder, then carrying out a heat treatment to provide a body formed from insulated soft magnetic metal powder the method comprising: compacting and molding the powder; then magnetically annealing the powder at a high temperature above the Curie temperature for the soft magnetic metal powder and below the threshold temperature at which the insulating film is destroyed in a non-oxidizing atmosphere, such as a vacuum, inert gas, or the like; and then carrying out a further heat treatment at a temperature of from 400° C. to 700° C. in an oxidizing atmosphere, such as air, or the like.
