Blocking device for a motor vehicle door

A central interlocking system for a motor vehicle performs in a normal operation all opening and closing functions. A vehicle provided with the system can be opened and locked without the operation of door closing motors. The outer and inner handles can be selectively blocked individually and jointly by a motor operated control member having two parallel control discs which cooperate with two locking levers. The control member can be released for opening of the door also in a purely mechanical way by turning a door lock keybolt with a key. The locking system has a simple construction and locking motors operating without loads.

A power-assisted hand brake for motor vehicles, which can be operated in an automatic and power-assisted mode with the aid of an electric motor. If the power assisted brake fails, a conventional parking brake is operated mechanically to apply emergency brakes. The handbrake includes a rotatable spindle with a threaded nut thereon which operates the brake by use of the motor. A carrier plate and pivot plates function to disconnect the nut so that a hand-operated lever can be used to manually operate the brake.

A system for transferring a control position of a set-point value transducer between the gas pedal and the throttle valve. The system includes an electromechanical device which can adjust a throttle valve out of its position of reponse in opposite directions. This is attained by an intermediate element, which is capable of coming to rest on a repose-position stop. The system is particularly well suited to motor vehicles having traction and/or cruise control.

An apparatus which serves to actuate the throttle valve of an internal combustion engine of a motor vehicle. The actuating device includes a reversible electric drive motor, the output shaft of which is operatively connected to the throttle valve, which is pivotable via a throttle valve shaft. The set-point pivoted position of the throttle valve can be predetermined by means of a gas pedal. A simple, economical design of such an actuating device is attained by coupling the throttle valve to a stop such that they rotate together; associated with the stop is a counterpart stop that is spring-loaded in the closing direction of the throttle valve by a restoring spring. The counterpart stop is coupled with the gas pedal in such a way that it is moved by the drive lever counter to the force of the restoring spring.

Device for actuating the throttle valve of an internal combustion

A device that serves to actuate a throttle valve. The actuating device includes an electric drive motor and a step-down gear driven by the motor; an output shaft of the step-down gear is operatively connected to a throttle valve shaft which controls the throttle valve. The actuating device is compact in structure as well as versatile in use, even with various sizes of throttle valve, the step-down gear is embodied as a planetary gear having its output shaft provided with a gear wheel, which is operatively connected via a toothed belt with a second gear wheel, disposed on the throttle valve shaft. The motor is controlled by a control means assembled in the same housing as the motor and the throttle valve.
