US 6,474,488 B1 · Electrical contact coupling for automatic center- or central buffer couplings for rail vehicles

Abstract

An electrical contact coupling (3) is provided for automatic center- or central buffer couplings for rail vehicles, more particularly for claw couplings with protective arm, rotatable claw and fall bar of the “AAR” or “Janney” type or with two rigid claws and claw bar of the “Willison” type. The coupling has a contact carrier (8) secured to the coupling head and guided so as to be displaceable longitudinally in the longitudinal direction of the center buffer coupling. An economic and flat-construction solution, indicated for a center- or central buffer coupling of the aforementioned type, for the design and arrangement of an electrical contact coupling (3) and an air line coupling (12) is achieved wherein the longitudinally displaceable contact carrier (8) is arranged underneath and on a supporting unit (1) which for its part is elastically supported on and secured to the coupling head underneath the said coupling head. At least one actuating cylinder (6) is arranged within the supporting unit (1) for the longitudinal displacement of the contact carrier (8). An air coupling (12) with an orifice (11) is arranged on the supporting unit (1) in the coupling plane.

Dependent claims

An electrical contact coupling for rail vehicles with a coupling head for claw couplings with a protective arm, rotatable claw and fall bar, the coupling comprising:

a supporting unit and an elastic support securing said supporting unit to the coupling head underneath the coupling head;
a contact carrier secured to the coupling head and guided so as to be displaceable longitudinally in a longitudinal direction of a central buffer coupling, said contact carrier having contacts for electrical connections provided on the contact carrier and displaceable from a rear, uncoupled position into a forward position ready for coupling, said contact carrier being arranged underneath and on said supporting unit;
a swivelable protective flap covering the contact carrier in a rear position and being freed in the forward position as the protective flap is swivelled;
actuating cylinders arranged within said supporting unit for the longitudinal displacement of the contact carrier;
an air line coupling with an orifice, said air line coupling being arranged on the supporting unit in the coupling plane.
