Abstract
A modular wheel and suspension assembly (MWSA) to provide mobility to a load for towing. The MWSA can have a fender housing and a suspension arm and suspension mechanism that is rotated toward a pivot arm with a suspension mount that engages with the suspension mechanism and a wheel. The suspension arm can be rotatably attached to the fender housing. A linear actuator can rotate the suspension arm to raise the fender housing while deploying the wheel from the fender housing. Rotating the suspension arm in the opposite direction causes the fender housing to be lowered over the wheel and the load to be lowered as the wheel retracts into the fender housing. The MWSA can have a rotary tongue system with an operable connection to the suspension arm. Rotating the suspension arm lowers and raises a tongue when the wheel is deployed from or retracted into the fender housing.
