| 20090062054 | MULTIPLE SPEED POWER TRANSFER UNIT - A power transfer unit for directing power to the front wheels and rear wheels of a motor vehicle includes an input, a rear drive shaft driveably connected to the rear wheels, a first gear unit having an output for producing first and second ratios of a speed of the input and a speed of the gear unit output, a differential mechanism driveably connected to the gear unit output for driving right-hand and left-hand front wheels differentially, and a second gear unit driveably connecting the rear driveshaft and the output of the first gear unit. | 03-05-2009 |
| 20090253548 | TORQUE VECTORING AXLE ASSEMBLY - In at least one embodiment of the present invention, a torque vectoring axle assembly for a non-driven axle of a motor vehicle is provided. The assembly comprises a first torque vectoring system ( | 10-08-2009 |
| 20090270217 | DIFFERENTIAL GEAR UNIT FOR MOTOR VEHICLES HAVING CONTROLLABLE DRIVING POWER DISTRIBUTION - A differential gear unit for motor vehicles for the controllable distribution of the driving power comprises a housing and a differential gear ( | 10-29-2009 |
| 20100144483 | YAW ASSEMBLY FOR A ROTATABLE SYSTEM AND METHOD OF ASSEMBLING THE SAME - A yaw drive assembly for a rotatable system includes an input shaft configured to receive a torque from a yaw drive motor coupled within a body of the rotatable system, wherein the torque facilitates rotating the rotatable system about a yaw axis. The yaw drive assembly includes at least two output shafts configured to receive the torque and transmit a rotational yaw force to the rotatable system, and a differential gear stage operatively coupled to the two output shafts, wherein the differential gear stage includes a differential planetary gear configured to drive a pinion coupled to each of the two output shafts. | 06-10-2010 |
| 20110045933 | HIGH TORQUE CAPACITY THREE OUTPUT DIFFERENTIAL - A differential for interconnecting an input member to a first, second, and third output member includes a housing interconnected with the input member and with the first output member, the housing having a first portion connected to a second portion, the first portion defining a first recess and the second portion defining a second recess, wherein the first recess and the second recess are aligned and cooperate to define a slot. A key member is disposed within the slot between the first portion and the second portion. A cross member is attached to the housing. A set of pinion gears is rotatable about the cross member. A set of side gears is intermeshed with the set of pinion gears, wherein one of the set of side gears is interconnected with the second output member and another of the set of side gears is interconnected with the third output member. | 02-24-2011 |
| 20120021864 | Drive axle system having a clutching device - A drive axle system for a vehicle drive train having a clutching device is provided. The drive axle system includes a first shaft, a first axle assembly, a second axle assembly, a first clutching device, and a second clutching device. The first axle assembly is drivingly engaged with the first shaft. The first clutching device divides one of a pair of output axles into first and second portions. The second clutching device selectively engages a driving gear of the second axle assembly with one of the first shaft and a portion of the first axle assembly. | 01-26-2012 |
| 20140011625 | GEAR REDUCTION MECHANISM - A gear reduction mechanism, particularly for use in an offset final drive unit for vehicular applications, has an input gear meshing directly with the output gear and two additional gear trains between the input and output gears. Three separate load paths therefore exist for the transmission of torque from the input gear to the output gear which means that the face widths of all the gears can be substantially reduced in comparison with a conventional single-mesh arrangement and the overall mechanism can therefore be of reduced width. | 01-09-2014 |
| 20140073472 | FOUR-WHEEL DRIVE VEHICLE - A power transmitting shaft transmits power of a driving force source to driven wheels. A differential gear is connected to an axle of the driven wheels. A ring gear is provided between the power transmitting shaft and the differential gear. A switching mechanism between the driving force source and the power transmitting shaft switches between a four-wheel drive state and a two-wheel drive state. A two-way clutch is provided between the ring gear and the differential gear. The two-way clutch switches between a power transmitting state and a power transmission interrupted state. | 03-13-2014 |
| 20140309074 | Transfer Case - A transfer case includes a planetary differential including an input, a first output and a second output, a sprocket journalled on the second output, and a sleeve driveably connected to the second output, for (i) releaseably connecting the first output to the sleeve, (ii) releaseably connecting the sprocket to the sleeve, (iii) releaseably connecting the first output and the sprocket to the sleeve, and (iv) disconnecting the sprocket and first output from the sleeve. | 10-16-2014 |
| 20140357445 | MODULAR POWER TRANSFER UNIT ASSEMBLY FOR A VEHICLE - A power transfer unit assembly for transferring torque from a differential carrier to a propeller shaft includes an input shaft configured to be rotatably driven by the transmission differential carrier about a first axis of rotation of the differential carrier. A first bevel gear is engaged with a second bevel gear. The first bevel gear is annular and concentrically surrounds the input shaft. The second bevel gear is configured to rotatably drive the propeller shaft about a second axis of rotation of the propeller shaft that is substantially perpendicular to the first axis of rotation. The power transfer unit assembly has a compound planetary gear set concentric with the first axis of rotation. The compound planetary gear set is configured to transfer torque from the input shaft to the first bevel gear at a reduction ratio. Modular power transfer unit assemblies having common components are disclosed. | 12-04-2014 |
