A control element for a motor vehicle having at least two steerable wheels provides that the actuating force in the transverse direction of the vehicle is measured redundantly by a control element transverse force sensor system and the control element angle is influenced by at least one electromotive control element actuator, whose rotational speed and torque are converted by a control element gearbox. Further, a control for a motor vehicle, provides for averaging the actuating forces exerted in the transverse direction of the vehicle on two control elements and using the averaged forces for influencing the radius of the trajectory of the motor vehicle while the actuating forces exerted in the longitudinal direction of the vehicle on the control elements are used for calculating a desired change of float angle of the motor vehicle.

Actuating part and control for a motor vehicle

The present disclosure describes a variable belt tensioner of an internal combustion engine for adjusting a belt tensioning. The tensioner includes in a series configuration an electric motor, a worm drive, a lever drive and a belt tensioner roller. The worm drive is driven by the electric motor and is mechanically connected to the lever drive for transmitting a rotation thereto. The lever drive is mechanically connected to the belt tensioner roller for transmitting a translation thereto, thus allowing the belt tensioner roller to adjust the belt tensioning.
