FR2967614A1 - Automatic mechanical coupler for coupling semi-trailer with tractor, has conical circular steel plate fixed under semi-trailer and specific ring, and specific ring provided with two guide arms - Google Patents

Abstract

The coupler has a conical circular steel plate fixed under a semi-trailer and a specific ring. The specific ring is provided with two guide arms for arranging contour of the plate between the semi-trailer and the tractor. A case of wiring is attached to twisted ring cables that are fixed on a junction box mounted on the semi-trailer.

Description

i

The present invention relates to the design of an automatic coupling mechanism for the coupling between a semi-trailer and a road tractor of maximum weight authorized by the road regulations. This automatic coupling system consists of a conical circular plate. of steel (fig 2) Fixed under the semi-trailer whose diameter or maximum width will be equal to that of the fifth wheel of the tractor, its conical thickness of a vertical angle of 10 to 45 degrees, should be between 10 and 15 centimeters in height; in the center and under this plate would be fixed by stamping the traditional hanging hook and that around this plate would turn by greasing a wrought iron ring (fig 1) marrying the conical shape of the plate, ring consisting of one or more parts, including two half-collars supporting two specifically shaped guide arms, supporting an interlocking box that would hold the male tapered air intakes and the male (either slat or pin-type) electrical outlets from the rear of this ring a cable transfer box would receive the rigid air and electrical cables-of-the-box-nesting passing around the ring and returning from this box cables Twisted flexible cables on a fixed junction box under the trailer supplying the brakes In air and the lights of the semi-trailer: to complete the automation of the semi-trailer, the lift of the stand would be carried out either by a motor Inverted trolley mounted on a traditional crutch Actuated from the cab by a reversing timer button or by a side-mounted kickstand by a cylinder actuated during the attachment of the tractor to the air while moving the semi-tractor unit ; for the stall a spring rappei.plus the air of the parking brake bottle of the semi-trailer would reposition the entire stand in the low position (semi uncoupled); concerning the device of the invention on the tractor a nesting housing grouping the female air intakes and the female electrical sockets would be fixed on the saddle (cabin side) by specific brackets with brackets with bumper spring to facilitate the branching and oscillatory movements, to complete the device a piston solenoid valve actuated by push button secure, located in the cabin would replace the manual and traditional system of unlocking the coupler lock of the fifth wheel of the tractor
