A vehicle drive system configured to achieve a required driving force of braking force without changing an orientation of a vehicle in the event of slippage of a wheel. The vehicle drive system comprises: a torque generating device; a differential mechanism that allows a relative rotation between a right wheel and a left wheel; a differential restricting device that restricts a differential rotation between the right wheel and the left wheel; and a steering mechanism that controls a turning angle of pairs of the wheels. A first controller controls the relative rotation between the right wheel and the left wheel to be smaller than a predetermined value and second controller further controls a turning angle of the wheels controlled by the steering mechanism.

An electrical axle drive device includes at least one first electrical machine, which has a stator and a rotor rotatable around a machine axis of rotation relative to the stator. A gear unit is drivable by the first electrical machine having at least one first planetary gear stage drivable by the first electrical machine and at least one first spur gear stage drivable by the first electrical machine. The device also includes at least one drive wheel of the motor vehicle being able to be rotated around a wheel axis of rotation running parallel to the machine axis of rotation and being drivable by the first electrical machine via the gear unit. The first electrical machine is arranged at least partially on a first side of the longitudinal central plane with respect to a longitudinal central plane of the vehicle that is spanned by the vehicle vertical direction and the vehicle longitudinal direction and the first spur gear stage is arranged on a second side of the longitudinal central plane opposite the first side in the vehicle transverse direction.

An actuation mechanism, a flap mechanism, and an aircraft. The actuation mechanism includes drive links and drive mechanisms connected to opposite ends of the flap that move the flap to various positions. The drive mechanisms are actuated by torque tubes connected to a drive motor via a differential. The differential distributes torque to the torque tubes. In the event of abnormal operation of one of the drive links or drive mechanisms, the differential limits torque to the remaining drive link and drive mechanism such that the flap does not deploy or retract in a skewed manner.

A method of detecting a ball loss condition in a ball and ramp assembly. The method includes providing a drive unit having one or more clutch pack assemblies, one or more motors with a motor output shaft and one or more ball and ramp assemblies. One or more actuation profiles are ran by the motors and an amount of motor current used and a position of the output shaft of the motor is measured during the running of actuation profiles. One or more motor current vs. motor output shaft position plots are generated having one or more characteristic curves based on the amount of current measured and the position of the output shaft measured. The amount of motor current is compared to the motor current of characteristic curve at a given output shaft position and based on that comparison a ball loss condition is identified.
