An improved differential unit (101) for an integrated hydrostatic transmission (IHT) is provided. The differential unit comprises an input gear (200), a cross-shaft (202) disposed within a central opening of the input gear, and a pair of clutch members (204L,204R) disposed coaxial with the input gear. One of each clutch member is disposed on opposite sides of the cross-shaft. A first plurality of friction members (208) extend from each clutch member. The differential unit also comprises a pair of side couplings (210L,210R), each coaxially disposed within one of the clutch members, and a second plurality of friction members (212) extending from each side coupling. Each clutch member includes a cam surface (206) that comes in contact with the cross-shaft when the differential unit is under normal operating conditions. Alternative embodiments are also described herein.

A vehicle driving force control apparatus is configured to prevent co-rotation of the motor caused by rotation of a pair of wheels when a clutch connecting the wheels and the motor is released (disconnected). When the clutch is released, the motor is braked by short circuiting the armature. The motor is then braked again by setting the field current of the motor to 0 when the rotational speed of the motor reaches 0. After the clutch is released, a braking-direction field current is applied to the motor in accordance with the decreasing rotational speed of the motor such that the braking force is decreased as the rotational speed of the motor decreases.

The invention relates to an individual wheel drive for individually suspended wheels of a motor vehicle comprising a joining shaft (2) which connects the output shaft socket (10) of a drive device to the input shaft socket of a wheel and has a main cross-section (4) and at least one end cross-section (8) rotatably coupled with the output shaft socket (10) arranged on the end above a homocinetic joint (6), wherein the joining shaft (2) has a permanent inclined position compensating the offset between the drive device and means for reducing a permanent deviation angle due to said inclined position is provided. The end cross-section (8) associated with the homocinetic joint (6) and the shaft socket (10) coupled to said cross-section are connected to each other by means of a bevel gear pair (16, 18) whose deviation angle (α) corresponds, at least partly, to a permanent deviation angle between the joining shaft (2) and the shaft socket (10).

A hydrostatic transaxle (3) is provided for a vehicle having a first axle (55) and a second axle. The hydrostatic transaxle comprises: a hydraulic pump (17); a first hydraulic motor (19) drivingly connected to the first axle; a closed circuit fluidly connecting the hydraulic pump to the first hydraulic motor; and a fluid-supply switching device shifted between a supply position for supplying fluid from the closed fluid circuit to a second hydraulic motor, which is disposed on the outside of the hydraulic transaxle and is drivingly connected to the second axle, and a supply-stop position for stopping the supply of fluid from the closed fluid circuit to the second hydraulic motor. The first hydraulic motor is variable in displacement, and the hydrostatic transaxle further comprises a linkage system for associating the switching of the fluid-supply switching device between the supply position and the supply-stop position with operation for changing the displacement of the first hydraulic motor.

The application relates to varied torque distribution between driven wheels or driven axles. It provides a differential torque generator comprising a main differential (5) including drive shafts (7RR,7RL) and a supplemental differential (10) including first and second rotary members (14a,14b), driven by a motor (20) and each rotationally connected to the first and second shaft. The drive shafts (7RR,7RL) are arranged coaxially, as are the rotary members (14a,14b). The axes of rotation of the shafts (7RR,7RL) and rotary members (14a,14b), however, do not coincide. Further independent claims are included for planetary gearsets used for driving the rotary members (14a,14b).

Disclosed is a 4-wheel drive of hydraulic manual and automatic transmission of a vehicle running on a road by transmitting rotational engine force to rear wheels, which allows manual or automatic gear shifting using hydraulic rotary machines rotating a main shaft by hydraulic pressure and hydraulic rotary machines independently installed to each wheel and allows to drive 4-wheels including front wheels whitout use of a differential gear. A transmission control panel that is installed to a center portion of a steering wheel and acts as a manual and automatictransmission causing instant gear shifting without a differential gear or a clutch by manipulating a transmission level and a transmission switch in a convenient and easy way. A switch device having many switches concentrated on the fixed center portion of a steering wheel to allow a user to rapidly turn on or off the switch buttons during stopping or running.
