Wheel Set Assembly

An improved wheel set assembly specially for transport vehicles and similar for heavy loads, wherein each wheel assembly comprises:

• a fork or cradle to make an angular turn of the platform in relation to its vertical axis, two internally hollow independent motorised wheels located on the same central horizontal axis and separated by a certain distance, which are supported by internally hollow supports
• an activation motor that is fitted to the stated fork or cradle, and
• which is provided with an internal reduction mechanism and an internal differential mechanism (D) so that under the conditions of a change of vehicle trajectory, one of the motorised wheels is able to turn at a different speed to the other motorised wheel with both wheels still being able to maintain the same torque;
• and
• said internal reduction mechanism and said internal differential mechanism (D) being housed in the cavity formed on the inside of the supports of the two motorised wheels.
