  • Publication number: 20060156846
    Abstract: The present invention relates to an actuator drive mechanism with a control motor (1), which on the power takeoff side drives a control gear that includes a final control element (3) on the drive side and a final control element (5) on the power takeoff side. The final control element (5) on the power takeoff side cooperates with an adjusting element (11), by way of which engines or machines can be varied in their operating behavior. Associated with the final control element (3, 5) on the drive side or the power takeoff side is a power takeoff component (8), which includes a force-transmission-free region (25), and on which a spring element (21) is received movably within a recess (19).

  • Patent number: 6969934
    Abstract: The invention is based on a control drive for operating drive components or adjusting components in motor vehicles. The control drive comprises an electric actuator (12) that acts on force-transmitting elements (19, 13; 40, 41). With these, the adjusting motion is transmitted to the drive or adjusting components to be adjusted. A throwout element (19) is provided that interrupts the transmission of force by the force-transmitting elements (10, 13; 40, 41) in the de-energized state (23, 55) of the electric actuator.

  • Patent number: 6295891
    Abstract: 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.
