Abstract

1324822 Semi-trailer coupling mechanism KALMAR VERKSTADS AB 10 Aug 1970 [13 Aug 1969] 38424/70 Heading B7T In a mechanism for coupling a semi-trailer to a tractor, a fifth wheel 9 secured to the tractor 1 has an opening to receive a hollow king pin 30 secured to the semi-trailer, the fifth wheel including a hollow locking bolt 11 which engages and retains the king pin 30 after said king pin has been introduced into said opening. The locking bolt 11 is mounted in a bearing bushing 12 supported by a sleeve-shaped portion 14 of the fifth wheel 9. The locking bolt 11 is moved downwardly by compressed air fed to a box 21 via conduit 28, and upwards by a spring 20. The vertical movement of the king pin 30 is prevented by flange 34 engaging in a groove 35 beneath a flange 36 of the fifth wheel 9. The fifth wheel 9 is mounted on a vertically movable section 6 pivoted to the tractor frame 11 at 17a and 17b. A lifting device 5, which may be electrically, pneumatically or hydraulically operated, is provided to adjust the height of said fifth wheel. Mounted in the upper part of king pin 30 is a compressed air and electrical power connector to lead supplies of these from tractor to trailer, the connector being a box 40 rotatable in both the king pin 30 and the upper wall 46 of frame section 32 at the front end of trailer 2, compressed air being supplied via flexible air hoses 41 and electrical power via cables 42. Corresponding air and electric power lines are provided in the locking bolt. The electrical contacts are made via fixed contacts 54-59 in the locking bolt and spring loaded moving contacts 541-591 mounted in the king pin 30 in an insulator body 44. The compressed air connector, Fig. 12, comprises a locking ring 77 which keeps sealing means 76 and the valve member of a non-return valve 74 in position in the tube 70 providing automatic closure of the air pressure lines when they are disengaged. A swing arm (300) (Fig. 13 not shown) may be attached to the box 40 which will maintain its orientation relative to the tractor when tractor and semi-trailer are not aligned. This swing arm may be connected via wires (301) to control stabilizers for the semitrailer or for steering the rear axle of the semitrailer. Pneumatic, hydraulic and/or electrical connections between the coupling mechanism and the driver’s cab provide information for the driver by means of light signals in the cab and enable him to control the coupling procedure therefrom (Figs. 14 and 15, not shown).
