Automatic coupling for draw bar - has sprung socket around drawbar to complete supply connections

摘要

The coupling drawbar has a bell shaped socket (2) into which a cone shaped fitting (1) on the end of the drawbar is pushed. The cone and bell have couplings for the electric and hydraulic lines which are automatically coupled when the two sections are pushed together. The cone slope provides a self locating control without the driver having to leave the cab. The bell is pivoted to allow drawbar adjustment on cornering. A PTO drive shaft (13) can be located through the centre of the coupling with a plined connection for a push fit.
