Description
Technical Field
The invention relates to a driving wheel, in particular to a combined multidirectional driving wheel.
Background
Combined multi-directional driving wheels, also known as mecanum wheels, are mainly used in all-directional movement modes. This is based on the principle that a number of peripheral axles, i.e. rollers, located on the centre wheel rotate around the centre wheel, these angled peripheral axles transferring the centre wheel steering force of one part of the moving system consisting of a number of centre wheels to the normal force of another part of the centre wheels. Depending on the direction and speed of the respective centre wheel, the resulting combination of these forces produces a resultant force vector in any desired direction, thereby ensuring that the platform is free to move in the direction of the resultant force vector, without changing the direction of the centre wheel itself. The current Mecanum wheel is connected through the nut between running roller and wheel hub, and the running roller axle is that can axial displacement, under the condition of running roller atress, can make the running roller axle produce the drunkenness easily, influences the removal precision of Mecanum wheel. Therefore, the conventional technology has a problem that the moving precision is easily affected.
