Abstract
A device for controlling the return of the coupling head for central couplings to their central position, especially for use in connection with rail vehicles, in which the coupling head is by means of a coupling rod linked to a housing arranged on a vehicle. A cam operatively connected to the coupling rod extends between two abutments which in the horizontal path of the cam are displaceable hydraulically, electrically or pneumatically. In one end position of the abutments, the full horizontal lateral deviation of the coupling rod is available, whereas in the other end position, the cam is clamped in between the two abutments.
Claims15
A device for adjustably returning to central position in a horizontal plane the coupling head of central couplings, especially for automatically connecting individual rail vehicles, which includes in combination:
- a coupling rod, housing means for mounting on a vehicle to be coupled, said coupling head being pivotally connected to said housing means through the intervention of said coupling rod, cam means movable in a horizontal plane and operatively connected to said coupling rod, two adjustable abutment means respectively arranged on opposite sides of said cam means for cooperation therewith, and power operable means operatively connected to said abutment means and operable to move said abutment means along said horizontal plane from a first position corresponding to the central horizontal position of said coupling rod in which said cam means is clampled in between said abutment means to a second position in which said coupling rod occupies the position of its maximum lateral horizontal deviation from said first and thereby said central position, and vice versa, dish-shaped means having said cam means arranged thereon and being directly connected to said coupling rod, and a cushion of rubber material, said cam means being arranged on said dish-shaped means, and said dish-shaped means being frictionally connected to said coupling rod through said cushion, a sliding member and guiding means for guiding said sliding member, one end of said intermediate lever means being pivotally connected to said sliding member, and said sliding member being rigidly connected to said piston rod.
