Abstract
A motion transmitting apparatus wherein an electric motor, an engine or another prime mover rotates an axially fixed first part relative to a coaxial axially movable non-rotatable second part. The structure which serves to move the second part axially in response to clockwise or counterclockwise rotation of the first part includes a follower borne by the first part and a helical spring having end convolutions affixed to the first part. The follower extends between two intermediate convolutions of the helical spring. If the apparatus is utilized in the power train of a motor vehicle, the axially movable part can serve to engage or disengage or change the extent of engagement of the friction clutch between the output element of the engine and the input element of the change-speed transmission.
Claims107
Apparatus for effecting relative movements of first and second parts at least one of which is turnable relative to the other, comprising:
- at least one tracking device fixed relative to said first part;
- a helix non-rotatably associated with said second part and having a plurality of convolutions including first and second packages of neighboring convolutions, each of said packages comprising abutting convolutions and said tracking device having a portion extending between at least two of said convolutions;
- and
- means for turning said one part relative to said other part.
Apparatus for effecting relative axial movements, comprising:
- first and second parts at least one of which is rotatable relative to the other about an axis common to said first and second parts;
- at least one tracking device fixed relative to said first part as seen in the direction of said axis;
- a helix non-rotatably associated with said second part and having a plurality of convolutions including first and second packages of neighboring convolutions, each of said packages comprising abutting convolutions and said tracking device having a portion extending between at least two of said convolutions;
- and
- means for rotating said at least one part relative to said other part.
Apparatus for effecting relative movements of first and second parts at least one of which is turnable relative to the other, comprising:
- at least one tracking device fixed relative to said first part;
- a helix non-rotatably associated with said second part and having a plurality of convolutions, said tracking device having a portion extending between at least two of said convolutions;
- and
- means for turning said one part relative to said other part, said other part being non-rotatably affixed to a shaft and the one pad being braked against a housing for the purpose of actuating the apparatus in a first axial direction whereas, for the purpose of actuating the apparatus in a second axial direction, said one part being non-rotatably affixed to the shaft and the other part being braked against the housing.
