VECTORING AXLE DRIVE
An electrical vehicle includes an electric machine and a vectoring motor that propel the vehicle. The vectoring motor drives a right axle shaft and a left axle shaft axle through a torque multiplier. First and second planetary gear sets are connected to right and left ends of a linking shaft that extends through a central opening defined by a rotor and a tubular output shaft of the motor. Torque is provided through the linking shaft to the first and second planetary gear sets. First and second grounding clutches normally lock the first and second planetary gear sets to a case of the vectoring motor. The grounding clutches are selectively and partially released to allow the ring gear of one of the first and second planetary gear sets to reduce a torque output of one of the first and second planetary gear sets to right and left axle shafts.
Drive device for a vehicle axle of a two-track vehicle
A drive device for a vehicle axle, especially a rear axle, of a two-track vehicle, wherein the vehicle axle includes an axle differential, which can be connected at the input end to a primary drive machine and can be connected at the output end across flange shafts arranged on either side to vehicle wheels of the vehicle axle, wherein the vehicle axle is associated with an additional drive machine and a shiftable superimposing gear, which can be shifted to a torque distribution gear in which a drive torque is generated by the additional drive machine, a torque distribution on the two vehicle wheels can be changed depending on the magnitude and direction of rotation of the drive torque, and shifting can be done to a hybrid mode in which the drive torque generated by the additional drive machine can be coupled to both flange shafts of the vehicle wheels.
DRIVELINE INCLUDING A VARIABLE END REDUCER ASSEMBLY
A driveline assembly for a vehicle including at least one primary shaft rotatable about an axis. At least one reducer assembly is coupled with the at least one primary shaft. The reducer assembly includes a sun gear rotatable with the primary shaft. A plurality of planet gears are rotatable about the sun gear. A ring is positioned about the planet gears. A planet carrier is rotatably connected to a center of each of the planet gears. An output shaft is fixed to the planet carrier. A sliding clutch fixes the ring to a ground in a high torque position to provide a gear reduction, and fixes the ring to the planet carrier in a low torque position to provide a 1:1 gear ratio. A method for operating such a driveline assembly is also provided.
TORQUE VECTORING DEVICE
A downsized torque vectoring device that is easily to be mounted on an automobile. The torque vectoring device comprises: a differential mechanism that allows a first driveshaft and second driveshaft to rotate at different speeds; an actuator that applies a control torque to the differential mechanism to rotate the first driveshaft and the second driveshaft at different speeds; and a reversing mechanism that allows the first driveshaft and the second driveshaft to rotate in opposite directions. A gear ratio of a first gear train and a gear ratio of the second gear train are different from each other.
In-line torque biasing mechanism
A differential device may include a housing having an inner surface and an outer surface, said inner surface having an outer ring gear and said outer surface having a first receptacle and a sun gear positioned within the housing, the sun gear having a second receptacle positioned opposite the first receptacle. The differential device may further include an intermediate gear interposed between the sun gear and the outer ring gear, a bearing interposed between the inner surface of the housing and the sun gear, and a central axis intersecting the first receptacle and the second receptacle. The housing and the sun gear may be configured to rotate freely about the central axis.

The reducer assembly includes a sun gear rotatable with the primary shaft. A plurality of planet gears are rotatable about the sun gear. A ring is positioned about the planet gears. A planet carrier is rotatably connected to a center of each of the planet gears. An output shaft is fixed to the planet carrier. A sliding clutch fixes the ring to a ground in a high torque position to provide a gear reduction, and fixes the ring to the planet carrier in a low torque position to provide a 1:1 gear ratio. A method for operating such a driveline assembly is also provided.
Hybrid axle drive with torque vectoring
An electric axle drive utilizes an electric motor to propel both half-shafts via final drive gearing and a differential. Torque vectoring gearing alters the torque distribution by transmitting power from one of the half shafts to the motor or from the motor to the half-shaft in response to engagement of brakes. Both the final drive gearing and the torque vectoring gearing are implemented using stepped planetary gear sets. The final drive gearing and differential are located on one end of the electric motor. The torque vectoring gearing is located on the opposite end of the electric motor.
