A planetary carrier where the second pinion gears are disposed so as to be at least partially located in the spaces between the adjacent bridge portions, an outer peripheral surface of each of the bridge portions is provided with a spline onto which a friction engagement plate constituting a friction engagement element is fitted, an inner peripheral surface of each of the bridge portions is provided with a pair of wall portions that extend in the axial direction along side edges on both sides of each of the bridge portions and protrude radially inward, and each of the bridge portions is provided with a plurality of oil holes through which an inside and an outside of each of the bridge portions communicate with each other.

A dual clutch transmission comprises a housing formed therein with a gear chamber incorporating an odd-numbered speed gear train group and an even-numbered speed gear train group. An end of the input shaft is connected to an engine, and a cover is detachably attached to the housing opposite the end of the input shaft so as to define a clutch chamber divided from the gear chamber. A first clutch for the odd-numbered speed gear train group and a second clutch for the even-numbered speed gear train group are disposed in the clutch chamber. Fluid passages for supplying hydraulic fluid to the first and second clutches are formed in the cover.

A brake device of a transmission according to the present invention includes: a rotary-side holding member including an inner peripheral surface having a cylindrical surface shape about an axis extending in a forward/rearward direction and configured to hold a rotary-side friction plate on the inner peripheral surface; a fixed-side holding member including an outer peripheral surface having a cylindrical surface shape about the axis extending in the forward/rearward direction and configured to hold a fixed-side friction plate on the outer peripheral surface; and a lubricating oil supply portion supplying lubricating oil to the fixed-side friction plate and the rotary-side friction plate. The fixed-side holding member is provided in a transmission casing so as not to rotate. The rotary-side holding member is provided in the transmission casing at a radially outer side of the fixed-side holding member and is rotatable about a central axis of the inner peripheral surface.

A vehicle driveline component having a dual friction clutch differential assembly and a hydraulic circuit for operating the friction clutches. The hydraulic circuit includes a pair of normally open, solenoid operated valves that are selectively closed to control the fluid pressure that acts on the friction clutches. The hydraulic circuit provides a simplified and cost-effective means for providing disconnecting and/or torque vectoring capabilities to the vehicle driveline component.

A gearbox for a motor vehicle. The gearbox comprises at least one fluid supply system. The fluid supply system comprises at least one pump. The fluid supply system comprises at least one fluid sump. The fluid supply system comprises at least one fluid reservoir. The fluid reservoir comprises at least a first fluid outflow leading into the fluid sump. The first fluid outflow can be controlled as a function of a state variable.

A clutch assembly includes a clutch housing, a clutch hub, a clutch pack and an oil deflector. The clutch pack includes at least one friction plate connected to one of the clutch housing and the clutch hub and at least one separator plate connected to the other of the clutch housing and the clutch hub. The oil deflector includes a circumferential wall and a flange. The circumferential wall includes a drain slot. The flange extends radially outwardly from an end of the circumferential wall and is mounted to one of the at least one separator plate and the at least one friction plate. The circumferential wall and the first flange cooperate to define a channel. Lubricant flowing along the clutch housing flows to the channel where the lubricant is directed away from the clutch pack and out of the drain slot.

An engine power unit for a vehicle has a crankcase made up of tow left and right crankcase members, and a lubricant feed pump disposed in one crankcase member in such a fashion that one side surface of pump rotors of the feed pump lies on the mating surface of the crankcase members. The feed pump is mounted on one end of the shaft of the feed pump while a drive gear for rotating the shaft is disposed on the opposite end of the shaft. A lubricant oil filter to which oil is delivered from the feed pump is disposed on the other crankcase member. Thus, the structure for supplying lubricating oil is simplified, and the power unit is reduced in size in its entirety.

A dual clutch unit includes an outer disk carrier rotationally driven about a rotation axis, first and second inner disk carriers, first and second disk packs for torque transmission between the outer disk carrier and the respective inner disk carrier, wherein the first and second inner disk carriers are arranged rotatably relative to each other about the rotation axis, a central oil supply to supply the first and second disk packs with coolant, a first distributor channel being formed in the first inner disk carrier and comprising a feed opening through which the first distributor channel is fluidly connected to the central oil supply, a second distributor channel being formed in the second inner disk carrier and being fluidly connected to the central oil supply via the first distributor channel, and drain channels being formed in the inner disk carriers to conduct the coolant into the disk packs.

An agricultural system including an agricultural baler and a control unit. The baler includes a driveline including at least one heat generating component; a rotatable flywheel; a rotary input shaft connectable by the driveline to the rotatable flywheel; and at least one pump for supplying cooling fluid at a cooling fluid pressure to the at least one heat generating component. The control unit is configured to: receive baler-data indicative of one or more operating conditions of the agricultural baler; receive cooling-pressure-data indicative of a flow of the cooling fluid supplied by the at least one pump; set a threshold-condition based on the baler-data; and provide a control-signal to the agricultural baler based on a comparison between the cooling-pressure-data and the threshold-condition.

A first valve is disposed in an oil passage through which the engaging pressure generated by a linear solenoid valve is supplied to A second brake. The first valve is closed when the second brake is released, so as to close the oil passage, and is opened when the second brake is engaged, so as to open the oil passage. A second valve is disposed in a lubricating oil passage through which lubricating oil is supplied to the second brake, and communicates with the linear solenoid valve. The second valve is opened when the engaging pressure is supplied from the linear solenoid valve, so as to open the lubricating oil passage, and is closed when no engaging pressure is generated by the linear solenoid valve.
