A module for a fluid circuit of a vehicle includes a unitary housing. The unitary housing of the module contains a fluid moving device, a fluid control device, and a power sharing connection. The power sharing device is configured to provide power to the fluid moving device and the fluid control device.

A vehicle temperature control system includes: a first temperature control circuit; a second temperature control circuit; a heat exchanger in which heat exchange between a first temperature control medium and a second temperature control medium is performed; and a control device. The control device is capable of controlling a carrier frequency and a flow rate control valve of the second temperature control circuit based on the temperature of the first temperature control medium detected. In a case where the temperature of the first temperature control medium is lower than a predetermined value, the control device is configured to set the carrier frequency to be lower and controls the flow rate control valve such that the flow rate to a second branch flow path is smaller, as compared with a case where the temperature of the first temperature control medium is equal to or higher than the predetermined value.

An electric drive unit and a drive axle system having an electric drive unit. The drive axle system also includes a drive shaft and an axle assembly that that is remotely positioned from the electric drive unit. The drive shaft operatively connects the electric drive unit to the axle assembly.

An apparatus for controlling an electric oil pump (EOP) includes a controller calculating first revolutions per minute (RPM), second RPM and third RPM, the first RPM being EOP RPM required for control of a brake in a transmission, the second RPM being EOP RPM required for cooling of a plurality of motors, and the third RPM being EOP RPM required for lubrication of the plurality of motors, the controller comparing the second RPM with the third RPM and driving the EOP at an RPM obtained by adding the first RPM to the greater of the second RPM and the third RPM.

A gear portion of a drive device is connected to a motor shaft. An oil passage through which oil to cool a motor flows includes a first oil passage, a second oil passage, a third oil passage, and a fourth oil passage. The first oil passage connects a gear accommodation portion and a pump accommodation portion. The second oil passage connects the pump accommodation portion and an oil cooler. The third oil passage connects the oil cooler and the fourth oil passage. The fourth oil passage connects the third oil passage and a motor accommodation portion. Each of the first oil passage, the second oil passage, and the third oil passage is in a first housing portion. The fourth oil passage is in a third housing portion.

A transmission including an electric machine, a torque converter and a planetary gearset in a transmission housing that is connected to an engine. A turbine shaft is configured to transfer torque from the engine and the electric machine to the planetary gear set. A disconnect clutch selectively couples the input shaft from the engine to the torque converter housing of the torque converter. The disconnect clutch includes a disconnect clutch piston and a first balance dam. A torque converter clutch selectively connects the torque converter housing to the turbine and the turbine shaft. The torque converter clutch includes a torque converter clutch piston and a second balance dam. Ports in the housing permit automatic transmission fluid to flow between the turbine shaft and the torque converter clutch piston; the turbine shaft and the torque converter clutch piston; and the turbine shaft, the first balance dam, and the second balance dam.

A vehicle drive device includes: a rotating electrical machine that functions as a driving force source for wheels; an input member drivingly connected to rotating electrical machine; a pair of output members each drivingly connected to wheel; a differential gear mechanism that distributes rotation transmitted from rotating electrical machine to pair of output members; a transmission gear mechanism that drivingly connects input member and differential gear mechanism; a hydraulic pump that includes a pump rotor and chamber housing the pump rotor and that supplies oil to at least the rotating electrical machine; and a case. The case includes a partition portion that separates in an axial direction a first housing chamber housing rotating electrical machine and a second housing chamber housing transmission gear mechanism and differential gear mechanism). Pump chamber is formed in partition wall so as to be located between first and second housing chambers in the axial direction.

A module for a fluid circuit of a vehicle includes a unitary housing. The unitary housing of the module contains a fluid moving device, a fluid control device, and a power sharing connection. The power sharing device is configured to provide power to the fluid moving device and the fluid control device.

A hydraulic supply system provides hydraulic power to functional systems of a work vehicle and includes first and second hydraulic circuits. The first hydraulic circuit includes a first fluid pump operable to generate a first hydraulic fluid, a pressure storage reservoir coupled with the first fluid pump, and a first port coupled with the first fluid pump and with the pressure storage reservoir operable to store a reserve hydraulic fluid. The first port delivers a boost hydraulic fluid from the first circuit for use by the work vehicle to operate a first functional system of the work vehicle. The second hydraulic circuit includes a second fluid pump that generates a second hydraulic fluid, and a second port coupled with the second fluid pump delivers the second hydraulic fluid from the second hydraulic circuit for use by the work vehicle to operate a second functional system of the work vehicle.

A gear portion of a drive device is connected to a motor shaft. An oil passage through which oil to cool a motor flows includes a first oil passage, a second oil passage, a third oil passage, and a fourth oil passage.
