Clutch motor

Claim 2

In a clutch motor, the combination of an electric motor, a flywheel operatively connected to said electric motor, a clutch wheel normally spaced away from said flywheel and engageable by the latter, a brake place normally engaging that surface of said clutch wheel remote from the flywheel, an axially movable sleeve type bearing having connected thereon said clutch wheel, a compression spring for normally urging said movable bearing in a predetermined direction, an operating lever coupled to said movable bearing operable to move same in said predetermined direction and the direction opposite thereto, and at least one electromagnet unit including a movable iron core connected to said movable bearing effective when energized to move said movable bearing in said opposite direction against the action of said compression spring while said operating lever is disabled.

Claim 3

A clutch motor as claimed in claim 1, wherein said operating lever has one end in the form of a yoke provided with a pair of opposite control pins and said sleeve-type movable bearing includes means defining a pair of opposite holes into which said control pins extend to normally form a free play on the side thereof remote from the clutch wheel sufficient to permit the clutch wheel to engage the flywheel.

Claim 4

In combination: a rotationally driven input member rotatable about a longitudinal axis; a stationary braking surface spaced apart from said input member along said longitudinal axis; a clutch disc having friction facings on each side thereof movable disposed between said input member and said braking surface; an output member connected to said clutch disc for movement therewith; mounting means mounting said clutch disc and output member for both rotary movement together about said longitudinal axis and translational movement together along said longitudinal axis between a first working position wherein said clutch disc frictionally engages with said input member and a second working position wherein said clutch disc frictionally engages with said braking surface; mechanical means for mechanically moving said clutch disc to said first and second working positions; and electromagnetic means electromagnetically effecting movement of said clutch disc to said first working position independently of said mechanical means.

Claim 5

In combination: a rotationally driven input member rotatable about a longitudinal axis; a stationary braking surface spaced apart from said input member along said longitudinal axis; a clutch disc having friction facings on each side thereof movable disposed between said input member and said braking surface; an output member connected to said clutch disc for movement therewith; mounting means mounting said clutch disc and output member for both rotary movement together about said longitudinal axis and translational movement together along said longitudinal axis between a first working position wherein said clutch disc frictionally engages with said input member and a second working position wherein said clutch disc frictionally engages with said braking surface; mechanical means for mechanically moving said clutch disc to said first and second working positions; and electromagnetic means electromagnetically effecting movement of said clutch disc to said first working position independently of said mechanical means.

Claim 6

A combination according to claim 3; wherein said mechanical means comprises a pivotally mounted operating lever connected to said mounting means, means mounting said operating lever for pivotal movement in one direction to one position to effect movement of said clutch disc and output member to said first working position and in the opposite direction to another position to effect movement of said clutch disc and output member to said second working position, and biasing means for normally biasing said operating lever in said opposite direction; and wherein said electromagnetic means comprises at least one magnetic member, means mounting said magnetic member for translational movement with said clutch disc and output member, and means spaced-apart from said magnetic member for selectively creating a magnetic flux coacting with said magnetic member to effect movement of said clutch disc and output member to said first working position.

Claim 7

A combination according to claim 4; wherein said mounting means includes a sleeve bearing disposed around a portion of said output member, means mounting said sleeve bearing for translational movement along said longitudinal axis, and means mounting said clutch disc and output member for translational movement witH said sleeve bearing and rotary movement relative to said sleeve bearing; means connecting said operating lever to said sleeve bearing to effect translational movement of same in response to pivotal movement of said operating lever; and means connecting said magnetic member to said sleeve bearing to effect translational movement of same in response to said magnetic flux.

Claim 8

A combination according to claim 5; including means defining a pair of holes in said sleeve bearing, and a pair of pins on said operating lever each positioned in one of said holes and cooperative therewith to effect translational movement of said sleeve bearing in response to pivotal movement of said operating lever, said holes being sufficiently oversized with respect to said pins to permit translational movement of said sleeve bearing by said electromagnetic means when said operating lever is in said another position.

Claim 9

A combination according to claim 6; wherein said rotationally driven input member comprises an electric motor and a flywheel having a surface portion frictionally engageable with said clutch disc rotationally driven by said electric motor.
