Abstract
Abstract To be able to automatically operate an electric vehicle coupling with a contact bush, there is provided a one way drive which both advances the contact bush (for coupling) and retracts it (for uncoupling) via an eccentrically mounted rolling wheel and a slide rail in which the rolling wheel slides. The rolling wheel has an eccentricity of (Δx+ε)/2, where Δx is a desired advance and ε is a compression advance.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
201 words
An electrical vehicle coupling between two rail vehicles, comprising: an electrical contact bush for each of said vehicles, each of said contact bushes being movable between an advanced position where said contact bushes are mutually coupled and provide electrical connection between said two rail vehicles and a retracted position where said contact bushes are mutually uncoupled; drive means for moving each of said bushes between said advanced position and said retracted position, each of said drive means including: an eccentric element mounted to a rotatable disk wheel at a position eccentric to the axis of rotation of said disk wheel; means for rotating said disk wheel in one direction; a slide rail associated with a respective said bush, wherein said eccentric element moves in a slide of said slide rail, whereby said bush moves from said retracted position to said advanced position and back to said retracted position for each revolution of said disk wheel; thrust pins on which said bushes are respectively mounted, said slide rails being respectively slidably mounted to said thrust pins for movement in the direction of the axis of said thrust pins, wherein each said slide extends perpendicular to a respective one of said thrust pins.
Claim 2
Dependent Claim
201 words
An electrical vehicle coupling between two rail vehicles, comprising: an electrical contact bush for each of said vehicles, each of said contact bushes being movable between an advanced position where said contact bushes are mutually coupled and provide electrical connection between said two rail vehicles and a retracted position where said contact bushes are mutually uncoupled; drive means for moving each of said bushes between said advanced position and said retracted position, each of said drive means including: an eccentric element mounted to a rotatable disk wheel at a position eccentric to the axis of rotation of said disk wheel; means for rotating said disk wheel in one direction; a slide rail associated with a respective said bush, wherein said eccentric element moves in a slide of said slide rail, whereby said bush moves from said retracted position to said advanced position and back to said retracted position for each revolution of said disk wheel; thrust pins on which said bushes are respectively mounted, said slide rails being respectively slidably mounted to said thrust pins for movement in the direction of the axis of said thrust pins, wherein each said slide extends perpendicular to a respective one of said thrust pins.
Claim 3
Dependent Claim
28 words
The coupling of claim 1 including spring means for elastically coupling each said bush to a respective said slide rail in the axial direction of said thrust pin.
Claim 4
Dependent Claim
49 words
The coupling of claim 2, wherein each said eccentric element has an eccentricity of: (Δx+ε)/2 where: Δx is a distance in the axial direction of each said thrust pin between said retracted position and said advanced position, and ε is a coupling compression advance of each said slide rail.
Claim 5
Dependent Claim
35 words
The coupling of claim 3, wherein said means for rotating each said disk wheel in one direction comprises a single directional motor and speed reducing gear means connected between said motor and said disk wheel.
Claim 6
Dependent Claim
30 words
The coupling of claim 4, including means for selectively disengaging each said speed reducing gear means from a respective said disk wheel, whereby said disk wheel may be manually rotated.
Claim 7
Dependent Claim
48 words
The coupling of claim 4, including means for releasing a mechanical coupling between said rail vehicles, comprising a cam mounted on a second disk wheel meshing with each said speed reducing gear means, and means for releasably coupling each said second disk wheel to a respective said cam.
Claim 8
Dependent Claim
46 words
The coupling of claim 4, wherein each said speed reducing gear means comprises: a first gear driven by a respective said motor and having means for selective coupling to a shaft thereof, and a reducing gear mounted to said shaft and meshing with said disk wheel.
