A rear vehicle module is interconnected in an articulated manner about a second vertical pin to the rear of the load-bearing bin, the rear vehicle module having at least one wheeled axle whereby the bin is supported by the front and rear vehicle modules. The rear module only articulates about the second vertical pin when the articulation of the front module to the bin exceeds 30 degrees and then in a synchronous manner. Typically the maximum articulation of the front module is around 42 degrees and the rear module some 13 degrees. | 05-23-2013 |
| 20150343901 | POWER TRANSFER UNIT - A power transfer unit includes an input shaft extending along an input axis and an intermediate drive shaft extending at least partially through the input shaft along the input axis. The power transfer unit further includes a ring gear assembly having a ring gear and a ring gear shaft coupled to the ring gear. The ring gear shaft at least partially surrounds the input shaft and extends along the input axis. The power transfer unit also includes a collar coupled to the input shaft. The collar surrounds the input shaft and is movable relative to the ring gear shaft along the input axis between an engaged position and a disengaged position. When the collar is in the engaged position, the input shaft is coupled to the ring gear shaft. When the collar is in the disengaged position, the input shaft is decoupled from the ring gear shaft. | 12-03-2015 |
| 20160039284 | VEHICLE AND METHOD OF CONTROLLING A VEHICLE - A vehicle having a four-wheel-drive system including an auxiliary portion that has an auxiliary driveshaft and drive means between the auxiliary driveshaft arranged to releasably connect a second group of wheels to the driveline via a releasable torque transmitting device. The releasable torque transmitting device is operable to allow slippage of the input portion with respect to the output portions, thereby to vary an amount of torque that is transmitted to the second group of wheels. | 02-11-2016 |
| 20160107523 | CONTROL APPARATUS FOR A VEHICULAR 4-WHEEL DRIVE SYSTEM - A control apparatus for a vehicular 4-wheel drive system provided with: primary drive wheels to which a drive force is transmitted from a drive power source; auxiliary drive wheels to which the drive force is selectively transmitted; a first clutch configured to selectively place a first power transmitting path in a power transmitting state and a power cutoff state; and a second clutch disposed in a second power transmitting path to selectively place the second power transmitting path in a power transmitting state and a power cutoff state. The first and second clutches are placed in fully released states to establish a 2-wheel drive mode. The control apparatus includes a first-clutch control portion configured to bring the first clutch into a partially engaged state when a predetermined condition in which the vehicular 4-wheel drive system generates or is considered to generate a noise is satisfied in the 2-wheel drive mode. | 04-21-2016 |
| 20160114680 | HYDRAULICALLY ACTUATED POWER TRANSFER UNIT - A power transfer unit for an all-wheel drive drivetrain that includes an engine, a transmission having a pump for circulating hydraulic fluid from a sump, and a driveshaft. The power transfer unit includes an input for receiving driving power from the transmission, an output for delivering driving power to the driveshaft, a first clutch, a first fluid supply path for delivering the hydraulic fluid from the pump to the first clutch, and a fluid return path for retuning the hydraulic fluid from the power transfer unit to the sump of the transmission. | 04-28-2016 |
