A joystick device having a grip assembly pivotably connected to a base assembly. The base assembly having sensing elements that detect the movement of the grip assembly as it pivots about the base assembly. Disposed within the base assembly and the sensing elements is a microprocessor. The microprocessor verifies an output signal prior to transmitting to a remote controller.

Joystick device with redundant sensor processing

A steering device with a steering angle transducer, a steering drive having a motor and a first gear, at least one wheel driven by the steering drive and a sensor arrangement for detecting the angle position of the wheel with a detection device, which produces a reference signal for at least one reference position of the steering device. In this connection, it is desired to improve the reliability of the steering device. For this purpose, the detection device is connected with the motor via a second gear.

Steering device

The invention concerns a steering arrangement ( ) with a steering handwheel ( ), which is unrotatably connected with a steering sensor, and with a wheel ( ) steered by a steering drive ( ) without a mechanically active connection between steering handwheel ( ) and steered wheel ( ). In this steering arrangement a simple way of realizing a counter action of the steered wheel on the steering handwheel ( ) is wanted. For this purpose the steering sensor is made as an electrical machine ( ), which works as a generator, for the production of a steering signal and is connected with a switching device ( ), whose load behavior is variable.

Steering arrangement

The invention concerns a steering arrangement ( ) for a vehicle, in particular for an automotive machine, with a steering drive ( ) controlled by a steering unit ( ). In a steering arrangement of this kind, it is endeavoured to make the steering less straining for the operator. For this purpose the steering unit ( ) has a keyboard ( ) instead of a steering handwheel.

Steering arrangement for a vehicle

The invention concerns a compact drive with an electric motor, a frequency converter and a gear. Such a drive should be made in the most compact way possible. For this purpose frequency converter is arranged at one front end of the motor and the gear is arranged at the other front end of the motor.
