  • Oil supply device and vehicle drive transmission device
    Patent number: 11739834
    Abstract: An oil supply device has: a first hydraulic pump driven by power transmitted through a power transmission path; a second hydraulic pump driven by a second driving force source independent from the power transmission path; and a hydraulic circuit. In a specific state in which a first forward speed is formed by oil discharged from the second hydraulic pump being supplied to a hydraulic drive portion, when a failure occurs in which a discharge pressure of the second hydraulic pump is decreased, a state of the hydraulic circuit is switched from a first state in which oil discharged from the second hydraulic pump is supplied to the hydraulic drive portion to a second state in which oil discharged from the first hydraulic pump is supplied to the hydraulic drive portion.

  • OIL SUPPLY DEVICE AND VEHICLE DRIVE TRANSMISSION DEVICE
    Publication number: 20210003196
    Abstract: An oil supply device has: a first hydraulic pump driven by power transmitted through a power transmission path; a second hydraulic pump driven by a second driving force source independent from the power transmission path; a first supply oil passage that supplies oil discharged by the first hydraulic pump to a lubrication required part of a transmission; and a second supply oil passage that supplies oil discharged by the second hydraulic pump to a hydraulic drive portion of a specific engagement device.
