10302186 · 2019-05-28 · ·

A transfer case comprises a primary output shaft, a secondary output shaft, a clutch, and a plurality of valves. The primary output shaft includes a hub rotationally coupled thereto. The clutch selectively couples the primary output shaft to the secondary output shaft to transfer torque therebetween. The clutch includes a housing, interleaved plates, and an apply plate. The housing is rotationally coupled to the secondary output shaft. The interleaved plates alternate between a first subset of the interleaved plates rotationally coupled to the hub and a second subset of the interleaved plates rotationally coupled to the housing. The apply plate compresses the interleaved plates for transferring torque between the hub and the housing. The valves selectively release oil supplied through the primary output shaft into the housing. Each valve includes a bore formed in the hub and a valve rod movable by the apply plate to open the valve.

Embodiments relate to an off-road vehicle comprising a frame, including at a frame, a passenger compartment, a driveline that includes at least a drive system and a driven system, and a constant velocity (CV) joint for coupling the driven system to the drive system. The CV joint includes a housing, a coupling shaft, a detent, a plunge pin and an actuation pin, wherein the actuation pin has a first end that is accessible via an aperture in the housing, wherein actuation of the actuation pin determines whether the plunge pin is in the first position or the second position.

Multi-mode powertrain for work vehicle providing selective power distribution between axles

A work vehicle includes a multi-mode power distribution assembly that selectively distributes power from a drive shaft between a first axle and a second axle. The power distribution assembly includes a plurality of clutches, each moveable between an engaged position and a disengaged position. The power distribution assembly includes a first mode, a second mode, and a third mode. In some embodiments, the first mode may be a four-wheel drive mode, the second mode may be an all-wheel drive mode, and the third mode may be an overdrive mode. Also, a park mode may be provided, wherein the clutches are in the engaged position.

Method for operating a multi-axle drive train for a motor vehicle, and corresponding multi-axle drive train

A device and a method for operating a multi-axle drive train for a motor vehicle. A first axle and a second axle are operatively connected, at least temporarily, to a drive device. When the second axle is decoupled from the drive device and a request for multi-axle drive with a first value is present, the second axle is coupled to the drive device only when a noise-masking event occurs, or when the second axle is coupled to the drive device and the request for multi-axle drive is absent, the second axle is decoupled from the drive device only when the noise-masking event occurs.

Positive Drive Differential

A positive drive differential assembly including a differential with an input pinion configured to operably engage with a drive shaft so as to permit the drive shaft to rotate the pinion. A bi-directional overrunning clutch assembly is configured to transmit torque between the pinion and two drive axle segments. A pinion disconnect assembly is provided for controlling transmission of rotation to the pinion and including a rotary coupler. A linear actuator is connected to the rotary coupler and configured to translate the rotary coupler between connected and disconnected positions.

Disconnecting all-wheel drive driveline having flat tow capabilities

An all-wheel drive vehicle driveline that includes a PTU input member, a spindle, a stub shaft, an axle shaft, a PTU clutch and a stub shaft clutch. The PTU input member, the spindle, the stub shaft and the axle shaft are rotatable about a first rotary axis. The axle shaft is received through the spindle. The PTU clutch is operable in a first PTU clutch mode, in which the PTU input member is rotatably coupled to the spindle, and a second PTU clutch mode in which the PTU input member is rotatably decoupled from the spindle. The stub shaft clutch is operable in a first stub shaft clutch mode, in which the stub shaft is rotatably coupled to the axle shaft, and a second stub shaft clutch mode, in which the stub shaft is rotatably de-coupled from the axle shaft.

Axle assembly with hydraulically-operated disconnect mechanism and spin-on hydraulic filter

An axle assembly can include a housing defining a reservoir and cylindrical bore open thereto. A clutch can selectively transmit torque between input and output members. A first inlet/outlet of a pump can be in fluid communication with the reservoir and define first threads coaxial with the cylindrical bore. The pump can be configured to pump fluid from the first inlet/outlet to an actuator of the clutch via a second inlet/outlet. The filter can include a base, port, and filter element. The port can define second threads that threadably engage the first threads. The base can be fixedly coupled to the port and include a cylindrical wall coaxial with the second threads. A seal member can form a seal between the cylindrical wall and the cylindrical bore when the first and second threads are engaged. The filter element can be disposed between the reservoir and the first inlet/outlet.

Multi-Purpose Vehicle
