My design is named tyre cell, it is also a kind of product used for vehicle transportation. It looks like a ball and contains one tire, a brake device, a pair of electric driving motors, a suspension, a tire rotating system (similar to tank turret) and a control unit. It can be considered an integrated single wheel chassis. Tyre cell uses electricity to work and is controlled by a vehicle computer using an electricity signal, so it's clean and has zero emission.

Tyre cell is general-purposed built and can be mounted on a motorcycle or a car. This makes the manufacture maintain and upgrade the vehicle more convenient.
