Truck and trailer coupling system - has automatic sliding draw-bar for trailer central shaft

摘要

The slidable drawbar is for a central shaft of a trailer. It has two gear wheels providing self steering. Turning point of truck/trailer coupling is 365 m/m behind the centre of coupling (1) of the trailer central shaft. The extra straight piece is via a pull eye connected to the clutch coupling via a stabilising device (2). Coupling includes gear wheel (5) connected to a pinion with a given transmission ratio. The drawbar has an outer casing (7) fixed to the trialer and inner housing (6) fixed to the turning point section. Both parts are slidable.
