Abstract: A cooling system includes a first cooling passage in which a first cooling object is cooled by first coolant, a flow passage that supplies the first coolant to a second cooling object from the first cooling passage, a flow rate regulation mechanism that regulates a flow rate of the first coolant flowing in the first cooling passage, and a controller that controls the flow rate regulation mechanism. The controller controls the flow rate regulation mechanism so that the flow rate of the first coolant flowing in the first cooling passage is lower when temperature of the first cooling object is lower than temperature of the first coolant, than the flow rate when the temperature of the first cooling object is equal to or higher than the temperature of the first coolant.

Abstract: A cooling system for a powertrain includes: a rotating electrical machine unit including a rotating electrical machine; and a power control unit configured to drive the rotating electrical machine. The cooling system includes: a radiator configured to cool a refrigerant; a refrigerant circulation circuit configured to supply the refrigerant flowing out from the radiator to a second cooled portion via a first cooled portion; a bypass flow path bypassing the second cooled portion; a flow control valve configured to adjust the ratio of a second refrigerant flow rate to a first refrigerant flow rate; and a control device configured to control the flow control valve. The control mode of the flow control valve includes a flow rate limiting mode in which the flow control valve is controlled to adjust the ratio such that the second refrigerant flow rate becomes less than the first refrigerant flow rate.

Abstract: An automatic transmission includes a main transmission and an auxiliary transmission. The auxiliary transmission includes an auxiliary-transmission-side planetary gear mechanism, a first clutch, and a second clutch. The auxiliary-transmission-side planetary gear mechanism is provided between a pair of main-transmission-side planetary gear mechanisms, and a part of the auxiliary-transmission-side planetary gear mechanism is located within the main transmission. The first clutch fixes rotation of a sun gear of the auxiliary-transmission-side planetary gear mechanism. The second clutch connects a ring gear of the auxiliary-transmission-side planetary gear mechanism with the sun gear.

Abstract: An automatic transmission includes: a main transmission including a plurality of main transmission side planetary gear mechanisms; an auxiliary transmission having a rotation axis different from a rotation axis of the main transmission; and a low/high switching mechanism switching between a low mode and a high mode by engaging and disengaging an engaging device provided on the auxiliary transmission. Further, the low/high switching mechanism switches between the low mode and the high mode at a point where a gear ratio in the low mode coincides with a gear ratio in the high mode.

Abstract: An automatic transmission includes a first engagement mechanism selectively engaging a first rotating member to a second rotating member, a second engagement mechanism selectively engaging the first rotating member to a third rotating member, and other engagement mechanisms. At least one of the first or second engagement mechanisms is a dog clutch. The automatic transmission sets intermediate, high and low speed stages by controlling the engagement mechanisms. The first engagement mechanism is kept engaged in shifting from the high speed stage to the intermediate speed stage. The second engagement mechanism is kept engaged in shifting from the low speed stage to the intermediate speed stage. When the automatic transmission sets the intermediate speed stage by controlling the other engagement mechanisms, a rotation speed of the rotating member that is coupled to the first rotating member by the dog clutch coincides with a rotation speed of the first rotating member.

Abstract: The present invention relates to a torsional vibration damping device in which a contact site with an inertial mass can be lubricated effectively while reducing resistance of the inertial mass to oscillate. The vibration damping device includes a rotary member that is rotated by a torque, and an inertial mass that is oscillated by torque pulses. The inertial mass is held in a chamber formed on the rotary member liquid-tightly together with lubrication oil while being allowed to be oscillated by torque pulses in the rotational direction of the rotary member. An amount of the lubrication oil is adjusted in a manner such that the inertial mass will not be brought into contact with an oil film of the lubrication oil centrifugally adhering to a radially outer section of an inner face of the chamber.
