1. 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.

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.
