8 Spoking the CargoPower motor RN 111
CargoPower installation and operation, revision - 01 65
8.4 Spoke pattern and spoke tensions
Basically, before spoking, the user must clarify which loads the spokes will be exposed to
during operation. The following conditions must always be met:
• Spokes must not be completely free of tensile stresses in any operating case
• Basic load + dynamic operating load ≤ max. permissible spoke load
8.4.1 Spoking symmetrical wheels
The CargoPower motor RN 111 are spoked symmetrically.
plane of the rim center = plane of the axle center
The plane of the axle center does not correspond to the center plane between the motor
flanges. Consequently, the spokes are of different lengths depending on the motor side
and are retracted and tensioned to different degrees.
In the front wheel, the motor flanges deviate to the right from the plane of the rim center
when the lacing is symmetrical.
In the rear wheel, the motor flanges deviate to the left from the plane of the rim center
when the lacing is symmetrical.
