Quick-action coupling for the connection of agricultural working machines

摘要

The invention relates to a quick-action coupling for the automatic connection of agricultural working machines to the links of the tractor hydraulics and to the power take-off shaft connection of a tractor. A tractor-side connection frame (5), which has a mounting for the tractor-side portion (8) of the cardan shaft, is provided. The mounting consists of two blocking members (23) which are mounted on the connection frame (5) so as to be pivotably movable under spring effect about pivot axes (22) pointing in the direction of travel. The tractor-side portion of the cardan shaft is thus fixed in an initial position allowing automatic coupling, this fixing being cancelled automatically after the connection of the connection frame (5) to the appliance frame (7) has been made. <IMAGE>
