Abstract

Abstract An electric regulating device, particularly for a speed control device for motor vehicles, with a servomotor and a rotatably mounted element which actuates the regulating member, the rotatable element particularly being a cable pulley which stands in operative connection with the servomotor via a gearing and a coupling device containing an electromagnet. At least one of the gears of the gearing is radially and at an angle or axially moveable mounted, and is connected indirectly or directly with an armature, which in turn cooperates with the electromagnet.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 101 words
An electrical regulating device, particularly for a speed control device for motor vehicles, comprising a regulating member, means for actuating said regulating member, said means constituting a rotatably mounted element, said element is formed as a cable pulley, a servomotor, a coupleable mechanical gearing means and a coupling means therefor including an electromagnet for operatively connecting said cable pulley with said servomotor, an armature cooperating with said electromagnet, and said gearing means includes a plurality of gears, at least one of said gears of said gearing means being substantially radially and/or axially moveably mounted and being operatively connected with said armature.
Claim 2
Dependent Claim 101 words
An electrical regulating device, particularly for a speed control device for motor vehicles, comprising a regulating member, means for actuating said regulating member, said means constituting a rotatably mounted element, said element is formed as a cable pulley, a servomotor, a coupleable mechanical gearing means and a coupling means therefor including an electromagnet for operatively connecting said cable pulley with said servomotor, an armature cooperating with said electromagnet, and said gearing means includes a plurality of gears, at least one of said gears of said gearing means being substantially radially and/or axially moveably mounted and being operatively connected with said armature.
Claim 3
Dependent Claim 22 words
The electrical regulating device as set forth in claim 1, wherein said at least one gear is indirectly connected to said armature.
Claim 4
Dependent Claim 60 words
The regulating device as set forth in claim 2, with said one gear being radially moveable, further comprising a housing, said at least one gear constitutes a gearwheel having a shaft, said shaft is articulated on one end thereof on said housing, an arm disposed on said armature, and the other end of said shaft is disposed on said arm.
Claim 5
Dependent Claim 68 words
The regulating device as set forth in claim 3, wherein said one end of said shaft is formed semi-spherically, said housing is formed with a spherical indentation, said one end of said shaft is mounted in said spherical indentation, said other end of said shaft is formed into a pin-shaped set-off, said arm is formed with an opening, said set-off is inserted through said opening in said arm.
Claim 6
Dependent Claim 38 words
The regulating device as set forth in claim 4, wherein said cable pulley is operatively mounted on said housing, a carrier is secured to said housing parallel to said shaft, said arm is pivotally mounted on said carrier.
Claim 7
Dependent Claim 51 words
The regulating device as set forth in claim 1, wherein said gearing means includes a gearwheel operatively coordinated to said at least one gear, spring means for biasing said armature by a spring force for moving said one gear out of engagement with said gearwheel when said electromagnet is without current.
Claim 8
Dependent Claim 19 words
The regulating device as set forth in claim 1, wherein said gearwheel is coaxially secured to said cable pulley.
Claim 9
Dependent Claim 22 words
The electrical regulating device, as set forth in claim 1, wherein said at least one gear is directly connected to said armature.
Claim 10
Dependent Claim 34 words
The regulating device as set forth in claim 1, wherein said at least one gear has a shaft, said shaft and said at least one gear form an integral unit made of synthetic material.
Claim 11
Dependent Claim 30 words
The regulating device as set forth in claim 1, wherein said regulating means is a cable windably connected to said rotatably mounted element and articulated to the throttle control rod.
Claim 12
Dependent Claim 130 words
An electrical regulating device, particularly for a speed control device for a motor vehicle having a throttle control rod, comprising a motor vehicle speed control regulating means for adjusting the throttle control rod of the motor vehicle, means for actuating said regulating means, said actuating means constituting a rotatably mounted element, a servomotor, a coupleable mechanical gearing means and a coupling means therefor including an electromagnet for operatively connecting and disconnecting, said element with and from said servomotor, respectively, independently of the action and direction of rotation of said gearing means, an armature cooperating with said electromagnet, and said gearing means includes a plurality of gears, at least one of said gears of said gearing means being substantially radially and/or axially moveably mounted and being operatively connected with said armature.
Claim 13
Dependent Claim 130 words
An electrical regulating device, particularly for a speed control device for a motor vehicle having a throttle control rod, comprising a motor vehicle speed control regulating means for adjusting the throttle control rod of the motor vehicle, means for actuating said regulating means, said actuating means constituting a rotatably mounted element, a servomotor, a coupleable mechanical gearing means and a coupling means therefor including an electromagnet for operatively connecting and disconnecting, said element with and from said servomotor, respectively, independently of the action and direction of rotation of said gearing means, an armature cooperating with said electromagnet, and said gearing means includes a plurality of gears, at least one of said gears of said gearing means being substantially radially and/or axially moveably mounted and being operatively connected with said armature.
