The driveshaft strikes back, again ! (wink to Star Wars fans) It has 2 universal joints and slides with suspension.

This is (I guess) my fourth take on this crucial part…

This time I wanted to improve the clearance within the suspension assembly and improve working parameters (namely the maximum angles before it locks). I also wanted the sliding to work within my Unimog design parameters. So the driveshaft minimum length is 57 mm (blocked by the design - it will never shrink more) and its maximum operating length should not exceed 59 mm (constrained by the differential and portal axle positions). So the sliding yoke , the shaft and the depth of external connectors (to the differential and to the portal axle) dimensions are calculated so that no screw is needed.

The rounded shape makes for better clearance (15 mm diameter) and allows bigger angles (ca 25° in any direction).

For mounting instruction please look at my previous design.
