Length-adjustable holding device for the lower steering arm of a three-point coupling device |
摘要 |
The invention relates to a length-adjustable holding device (5) for supporting the lower steering arms of a three-point coupling device of an agricultural tractor. The holding device (5) comprises a helical spring (6) and an adjusting member (9). The spring and adjusting member are connectable to each other by means of through-bores (10) in the adjusting member (9) and a pin (11) insertable between two coils (6a, 6b) of the helical spring (6). The axes (12) of the through-bores (10) extend at an angle and the distance between the bores (10) differs from the pitch of the two coils (6a, 6b) in order to achieve a fine length adjustment. The adjusting member (9) is guided via a guiding projection (15) in a bore (16) of a guiding sleeve (14) which is received in the cavity of the helical spring (6) so as to be non-rotatable and axially unmovable.
