At the rear, the tried-and-examined single-joint swing axle turned into outfitted with a compensating spring, placed horizontally above the pivot factor as a way to distribute axle load similarly to each pressure wheels. The surprise absorbers at the the front and rear wheels had been now placed proper at the out of doors, a degree that now no longer handiest furnished greater powerful vibration damping however additionally stepped forward accessibility.

During the manufacturing length the brake machine underwent modifications. First the 220 Sb and 220 SEb had been prepared with disk brakes to the the front wheels in April 1962. Then in August 1963 the identical change turned into introduced to the 220 b and the version turned into concurrently prepared with a brake booster - a characteristic to be had up till that factor handiest at greater value.
