Device and method for transferring rotational power and method of using same

A multi-link transmission system for powering a suspended wheel of a vehicle, the multi-link transmission system comprises:

• an input shaft coupled to a rotational power source for providing a rotational power;
• an output shaft for transferring the rotational power to the suspended wheel of the vehicle;
• a first link and the second link, each comprises:
• a supporting structure;
• a first gear wheel and a second gear wheel, rotatably supported by the supporting structure;
• one or more gear wheels disposed in-between the first gear wheel and the second gear wheel to transfer rotational movement of the first gear wheel to the second gear wheel;
• wherein:
• the first gear wheel of the first link is adapted to be powered by the input shaft, the first gear wheel of the first link being a first gear wheel in the transmission system;
• the first gear wheel of the second link is rotatable by the first link;
• and
• the second gear wheel of the second link provides rotational power to the output shaft, the second gear wheel of the second link being a last gear wheel in the transmission system;
• wherein the input shaft is coaxial with the first gear wheel of the first link and the output shaft is coaxial with the second gear wheel of the second link;
• and
• wherein the first link and the second link have a common axis adapted to allow the first link and the second link to rotate freely about the common axis and thus to allow a change of an angle between the first link and the second link in both directions while the gear wheels of the first link and the gear wheels of the second link are rotating, such that the suspended wheel of the vehicle receives the rotational power when moving with respect to the input shaft in response to a movement of the suspended wheel.
