The working principle is as follows:
A circle of independent planet wheels with an inclination angle (45°) is arranged in the circumferential direction of the center wheel. These planet wheels control the forward speed of the center wheel. It is decomposed into two directions, X and Y, so the wheels can slide laterally to achieve forward and horizontal movement. ?
Depending on the direction and speed of the respective wheels, the final combination of these forces produces a resultant force vector in any required direction, thereby ensuring that the platform can move freely in the direction of the final resultant force vector, without changing the direction of the wheel itself.
The Mecanum wheel is a patent of Swedish Mecanum Company. This omnidirectional movement method is based on the principle of a center wheel with many axles located around the wheel. These angled peripheral axles convert part of the wheel steering force into a wheel normal force.
Depending on the direction and speed of the respective wheels, the final combination of these forces produces a resultant force vector in any required direction, thereby ensuring that the platform can move freely in the direction of the final resultant force vector, and Does not change the direction of the wheel itself.
There are many small rollers distributed diagonally on its rim, so the wheel can slide laterally. The busbar of the small rollers is very special. When the wheel rotates around the fixed wheel spindle, the envelope of each small roller is a cylindrical surface, so the wheel can continuously roll forward.
The Mecanum wheel has a compact structure and flexible movement. It is a very successful all-round wheel. There are four new wheels of this type that can be combined to achieve all-round mobility more flexibly and conveniently.
