The Mecanum wheel is more complex than ordinary tires. It is composed of many spindle-shaped rollers installed obliquely. The inclination of the rollers is 45°, so when driving and operating, the left and right forces will be very uniform. The middle position of the rolling rod is also higher than that of the other two sides, which is why the Mecanum wheel can change the direction of travel at will. Except for the rolling rod, the hub and axle are made of polyurethane and steel, so it The use will be more durable than other ordinary tires.
Operating principle
Its operating principle is not complicated at all. If you need to drive the car obliquely, let the two diagonal wheels rotate; It is enough to rotate the wheels in the opposite direction, so that even in an extremely narrow space, the mecanum wheels can be easily rotated, and driving will become extremely easy.
Scenario
Mecanum wheels are now widely used in various omni-directional mobile platforms, forklifts, wheelchairs, storage robots, stunt robots and various toys. All-round movement and all-round rotation, the huge advantages attract more and more technological attention. It can be used in industries such as heavy-duty machinery production, railway transportation, automated smart warehouses, supermarkets, large-scale automated factories, docks, ports, airports, and even aerospace.
The frictional force of the ground acting on the roller is decomposed into rolling friction and static friction. The rolling friction makes the roller rotate, which is an invalid motion; the static friction makes the roller move relative to the ground (similar to the movement of ordinary rubber tires), and the roller is "stuck" by the hub. Live", thus driving the entire wheat wheel to move along the axis of the roller (that is, the hub rotates counterclockwise, the direction of movement is 45° to the upper left; the hub rotates clockwise, and the direction of movement is 45° to the lower right).
