Abstract
An assembly with a lower steering arm has a strut 1 and an attaching end 16. To achieve a cost-effective design while at the same time reducing the play between the attaching end 16 and the end of the strut 1 received therein, the attaching end 16 includes a base member 18 and a cover 19. A blocking pawl 34 is supported in the base member 18. The cover 19 is welded to the base member 18 and comprises a stop face 30 for the end face 10 of the strut 1. Thus, any tolerances in the region of the base member 18 provided in the form of a forging do not affect the position of the stop face 30. The latter can be aligned when connecting the base member 18 and the cover 19. Because of its setting contour, the actuating lever 43 can be used for both the right hand and the left hand lower steering arm.
Claims10
A lower steering arm assembly for an implement attaching device, comprising:
- a strut pivotably attachable to a tractor or a self-driving working machine, an attaching end removably fixed to the free end of the strut providing a connection with an implement;
- the strut constituting one component and the attaching end a further component and with one of the components including a blocking pawl;
- an actuator, said blocking pawl being pivotable between a locked position and an open position, in the locked position said blocking pawl engaging a recess of the other component and in the open position, the blocking pawl is disengaged from said recess, and a spring loading said blocking pawl for assuming the locked position, said actuator including an actuating lever which is pivotable around a pivot axis, at least one actuating arm extending radially from the pivot axis, said actuator further including a setting contour on which the actuating arm is at least partly supported and an indentation with a base, in opposed pivoting directions of the actuating lever, setting faces risingly extending in the supporting region, and with a connecting element connecting the actuating lever with the blocking pawl at a distance from the pivot axis of the blocking pawl.
