Abstract:
A drive train having a locking differential and a control unit for controlling operation of the locking differential. The control unit is responsive to selected vehicle characteristics to sua sponte activate or inactivate a locking mechanism of the locking differential to cause the locking differential to operate in a locked manner or an unlocked manner, respectively. A method for operating a locking differential is also provided. The method includes: utilizing only preselected vehicle criteria indicative of the operational state of the vehicle to identify a situation in which a locking mechanism associated with the locking differential is to be energized; and responsively energizing the locking mechanism.
Abstract:
A transfer case includes an input shaft, first and second output shafts and a planetary gearset including a ring gear fixed for rotation with the input shaft. A planet carrier is fixed for rotation with the first output shaft. A range clutch is operable in a first range position to drivingly connect the ring gear and the planet carrier as well as in a second range position to restrict the sun gear from rotation to drive the first output shaft at a reduced speed. A mode clutch is operable to connect and disconnect the first output shaft and the second output shaft. A range actuator moves the range clutch between its first and second range positions. A mode actuator moves the mode clutch between its first and second mode positions. A control system controls the range clutch and the mode clutch.

Abstract:
A vehicle brake unit is provided for use with a drive train having a drive train subassembly. The brake unit comprises a brake unit housing for enclosing a braking mechanism, the braking mechanism arranged to act on a power shaft configured for operatively connecting the output drive shaft of the drive train subassembly with a further drive shaft, in order to transfer power therebetween. The brake unit housing is arranged for mounting directly to a housing of the drive train subassembly. In one embodiment of the invention, the brake unit housing replaces the rear tail housing of a four-wheel drive transfer case.

Abstract:
A dynamic speed regulator comprises a dynamic transmission mechanism, an output gear group, a multistage speed controller and a speed regulating mechanism, wherein the dynamic transmission mechanism connects a cushion mechanism and a power source unit. The first planetary gear group meshes with the input driven gear. The second planetary gear group is contacted with the output shaft. The output gear group mounted on the output shaft. The multistage speed controller meshes with the output sun gear through the third planetary gear group and a ring gear. The input gears of said speed regulating mechanism mesh with the output gears of the output gear group. Said speed regulator drives the input gear depending on the scheduled time. The output and input gear groups rotate in the destined ratio and drive the output shaft to rotate.
