6.2 Oscillating articulated joint

6.2.1 Repair overview for oscillating articulated joint...... 167
6.2.2 Removing and installing the oscillating articulated

joint........................................................................ 169

6.2.3 Repairing the oscillating articulated joint............... 170

Oscillating articulated joints are used to establish a moveable con-

nection between the rear and front frames of agricultural and con-

struction equipment. The machine can be steered around the ver-

tical axis by means of an articulated movement; the rear frame can

oscillate on the horizontal axis. The advantage of the oscillating

articulated joint is the fact that front and rear frame move in the

same track.

The oscillation compensates for uneven surfaces and creates an

even drum pressure. Both the pivot point of the oscillating joint,

which was purposely designed to be low, as well as the low centre

of gravity of the machine ensure good stability.
