Blocking apparatus, as well as a gearbox drive unit containing such a blocking apparatus, as well as a method for production of a gearbox drive unit such as this for blocking any rotary movement of a shaft () with respect to a housing () of a gearbox drive unit (), having a first blocking element () and having a second blocking element () which can be moved axially with respect to the first blocking element () by means of an electromagnet () and at least one return element (), in order to produce a connection between the first blocking element () and the second blocking element () such that they cannot rotate with respect to one another, with the electromagnet () having an inner pole () which is surrounded by an electrical coil (), and with the inner pole () having an axial projection () which engages in a corresponding opening () in the second blocking element (), for axial guidance and centering.

A rotary angle encoder in which the adjustment of the sensor signal desired in the starting position can be changed by simple manipulation. In the rotary angle encoder set forth herein, upon assembly, the coupling is slid only partially onto a cylindrical shaft connected to the sensor part in a first position. In this first position, the coupling can be rotated in relation to the sensor part. Then the sensor signal desired in the starting position is set and after that, the coupling is slid still further onto the cylindrical shaft so that an unintentional rotation of both parts in relation to each other is not possible after the adjustment is complete. The rotary angle encoder is provided for controlling the power of a vehicle drive unit.

In a pedal-travel sensor device with a kick-down mechanism, when the gas pedal is actuated, an electrical signal should be produced at the same time as a clearly perceptible jump in force. The pedal-travel sensor device proposed here is provided with leaf springs ( ) which provide electrical contacts. As a result, the production of the electrical signal can occur completely without play and at the same time as the production of the jump in force. The clearly perceptible jump in force is provided by a spring biased detent means. The pedal-travel sensor device is provided for controlling the power of a drive engine of a motor vehicle.

Pedal-travel sensor device

An accelerator pedal module is provided that is actuated by the driver's foot for controlling the output of a drive engine. Frequently undesirable noise is generated by means of characteristic vibration in the restoring springs of prior pedal modules. The accelerator pedal module of this invention includes an intertwined multi-wire spring which helps to eliminate undesirable vibration of the restoring spring. The accelerator pedal module is provided for controlling the output of a drive engine of a vehicle and forces the pedal module from a full load stop, back to an idle stop
