The invention relates to an electric steering and drive system for a vehicle having a wheel-based steering system, having drive elements for traction tracks or for wheels and having two drive shafts, the first end of which is connected to the drive element of the respective one vehicle side and the second end of which is connected to a differential gear mechanism arrangement, and at least one traction motor is connected to at least one of the two drive shafts, and having an electric steering drive which is drive-connected to the differential gear mechanism arrangement, it being possible for the traction motors and steering drives to be supplied with electric current from at least two energy sources which are independent of one another.

Electric steering and driving system for a lateral wheel-steering vehicle

A device for reversing a steering movement of a steering wheel shaft of a vehicle includes a switching element movable between two switching positions to activate or deactivate the reversal of the steering movement. A mechanical actuating device includes a shaft which is rotatable in different rotational directions, and a slide for actuating the switching element. The slide can be moved along the axial direction of the shaft as a function of the rotational direction of the shaft in order to transfer the switching element between the switching positions.

Device for reversing the steering movement of a steering wheel shaft

A cooling device for an electrical power unit of electrically operated vehicles, comprising at least one power section and at least one control section. A first cooling circuit containing a heat exchanger with a low coolant temperature is provided mainly for cooling elements of the control sections, and a further cooling circuit with a higher coolant temperature is provided mainly for cooling elements of the power sections.

Cooling device for electrical power units of electrically operated vehicles

The invention relates to an electrical steering and drive system for a vehicle with wheel-based steering with at least two electrically driven axles, a mechanical coupling between the drive sides being provided on at least one driven axle in order to transmit power from one drive side to the other, and a purely electrical transmission of drive power being provided on the other driven axles.

Electric steering and drive system for a vehicle with wheel side steering system

A fault-tolerant electromechanical actuating device for converting an electrical actuating signal into a mechanical output actuating value for use in vehicles, having two mutually independent control loops. Each loop has at least one controller and at least one electric motor which is driven by this controller and which, in each case via a self-locking transmission, drives the input to a summing transmission, which superimposes the actuating values of the actuating motors to form the output actuating value. The fault tolerance or reliability of the actuating device is ensured by a comparator controller, which monitors the functions of the other controllers. Interfaces between the controllers and between the subsystems ensure stringent isolation of electrical potential.
