A wheel structure with a built-in reducer and motor is provided. As the driving wheel in a rudder wheel, which has a high degree of integration and significantly reduces the overall height of the rudder wheel while maintaining high speed and acceleration. The wheel structure includes a wheel coupled to a reducer, a drive motor connected to the reducer, and the reducer.

A drivetrain for an agricultural vehicle includes a rear axle, and a front axle, a first electric drive unit, and a transmission. The transmission has a first output shaft connected to the rear axle. The drivetrain includes a front axle drive unit having a second output shaft. The first output shaft is connected to the second output shaft. The first electric drive unit is connected to the second output shaft. A torque can be introduced into the second output shaft by the first electric drive unit. The torque can be transmitted from the second output shaft via the transmission to the rear axle such that the rear axle can be driven by the first electric drive unit.

A wheel-driven vehicle (1), comprising a front vehicle unit (1 A), a rear vehicle unit (1B), a power source (4), a first centre beam (8) and a second centre beam (9), a first driving means (10) and a second driving means (11) provided on each opposite sides of the first centre beam (8), a third driving means (13) and a fourth driving means (14), provided on opposite sides of the second centre beam (9), wherein the respective driving means (10, 11, 13, 14) comprises at least a driving wheel (16), a power-transmitting arrangement for transmission of power from said power source (4) to the driving wheel (16) that is included in each of the driving means (10, 11, 13, 14), wherein the power-transmitting arrangement comprises an engine (19) and a transmitting arrangement (20). The engine (19) is a hydraulic engine, the power-transmitting arrangement comprises separate hydraulic circuits (22, 23, 24, 25) for driving the hydraulic engine (19) of the respective driving means (10, 11, 13, 14), the power-transmitting arrangement comprises one or more pumps (26, 27, 28, 29) driven by the power source (4) for driving the respective hydraulic engine (19) as well as regulating means configured to individually regulate a power output on the respective hydraulic engine (19).

A vehicle is described that includes a multi-mode powertrain system having a first drive unit and a second drive unit. A controller is arranged to monitor the high-voltage DC power bus and is in communication with and operatively connected to first and second inverters. The controller is able to detect operation of one of the first inverter or the second inverter in an uncontrolled generating (UCG) mode, determine a driveline torque associated with the operating of the one of the first inverter or the second inverter in the UCG mode, and determine a compensating torque that is needed to counteract the driveline torque associated with the operating of the one of the first inverter or the second inverter in the UCG mode. The controller can further operate to detect a fault that may induce unintended lateral motion (ULM), and control torque outputs of the inverters based thereon.
