Stabilizer for a lower guide arm and / or an upper guide arm of an agricultural tractor

摘要

Stabilizer for a lower and / or an upper guide arm of a three-point suspension of an agricultural tractor, where the stabilizer (1) has at least one telescope (8) consisting of a tube (5) and a piston ( 6) held displaceably therein, which are elastically coupled to each other through at least one spring (7), wherein the plunger (6) through at least one thread (12, 13 ) can be adjusted longitudinally by rotation and at least one lock bracket (15) is pivotally held in the tube (5) which in a locked position is coupled with at least one counter support (17) of the piston (6) ) and in a releasing position of the telescope (8) it can move freely, where the locking bracket (15) is coupled with the at least one counter-support (17) on both sides, characterized in that the counter-support (17) it is formed by at least one disk essentially with rotation symmetry, so that s e can make an adjustment of the length of the plunger at or near the locked position, in which the telescope (8) is locked.
