Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mobile structures, in particular to a Mecanum wheel mechanism. Background Art
[0002] Mecanum wheels rely on the direction and speed of each wheel. The final synthesis 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. There are many small rollers distributed obliquely on its rim, so the wheel can slide laterally. The generatrix of the small rollers is very special. When the wheel rotates around the fixed wheel axis, the envelope of each small roller is a cylindrical surface, so the wheel can roll forward continuously. The Mecanum wheel has a compact structure and flexible movement. It is a very successful omnidirectional wheel. There are four of these new wheels in combination, which can realize the omnidirectional movement function more flexibly and conveniently.
[0003] Although the existing Mecanum wheel mechanism can move in all directions, it cannot provide buffering. When walking on uneven roads, it is easy to produce large vibrations. Therefore, a Mecanum wheel mechanism is needed to solve the above problem. Utility Model Content
