The invention relates to a toothed belt () with two mutually oppositely arranged running surfaces (), wherein, on the running surfaces (), there are arranged toothings () arranged obliquely with respect to the axial direction (X), wherein the obliquity is defined in each case by helix angles () between the axial direction (X) and the direction of the tooth flanks of the respective toothings (). It is provided that the helix angle () of the first toothing () is oriented oppositely to the helix angle () of the second toothing ().

Toothed belt comprising running surfaces provided on opposite sides and having tooth systems, the helix angles of the tooth systems being oriented in opposite directions, and associated toothed belt gear

An apparatus is provided for measuring a torque in a force-feedback actuator for a steer-by-wire steering system has a housing element, a control unit, a drive apparatus, and a transmission apparatus to be coupled to a steering device. At least one motion sensor detects a motion of the transmission apparatus relative to the housing element and provide a motion signal resulting from the motion to the control unit. The transmission apparatus is coupled to the housing element by way of at least one reset-reversible adjusting device which has at least one mechanical property. A torque of the transmission apparatus, and thus of a connectable steering device, may be ascertained by the control unit using the at least one mechanical property, which has at least one changing state value during the movement of the transmission apparatus, in combination with the motion signal.

A steering handle for inputting a driver's steering command into a steer-by-wire vehicle steering mechanism comprises a rotatably mounted main part for actuation by the driver. A transmission is arranged in a receptacle on the main part, an input member of the transmission can be coupled to an electric motor, and an output member of the transmission is coupled to the main part.

Steering handle

A utility vehicle steering system includes a steering gear for transmitting a manual torque from a steering wheel to a steering drop arm. An electric motor provides an auxiliary torque for the steering boost, which is provided exclusively electrically over the entire operating range of the steering system. An input shaft and an output shaft have axes of rotation that are skewed with respect to each other. A first gear device couples the input shaft to the output shaft. A second gear device has the electric motor connected to the input side and has at least one speed-reduction gear stage in the form of a coaxial gear with a high transmission ratio. The output side of the second gear device is coupled to the output shaft and its speed reduction gear stage, a coaxial gear with a high transmission ratio, is coaxial with the output shaft.
