Dear TamiyaBase members,
I am currently builing the Tyrell P34 Six Wheeler and came across this combination of having a ball differential and a thrust bearing on one axle. What exactly is the technical reason for that? Would a ball bearing with - let's say a coil to bring the pressure on the bearing - not be sufficient already? I can understand the disk springs MC2 in the setup, kind of like a coil. But where is the need for the additional (thrust) bearing. I don't see any additional need for a circular movement of the wheel which would necessitate the bearing?

Enlighten me, please

Cheers

The thrust is here to permit the differential effect

ah yes, I get it. Since it is a solid axle that goes through both wheels, you need a pivot point. Makes sense! Thx Stingray!
