Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of suspension, in particular to a Mecanum wheel vertical suspension. Background Art
[0002] A mecanum wheel is a device that can move in all directions. This all-directional movement is based on the principle of a central wheel with many axles located around the wheel. These angled axles convert part of the wheel steering force into a wheel normal force. Depending on the direction and speed of the respective wheels, omnidirectional movement is often a necessary function of the mecanum wheel. Omnidirectional movement means that it can make any direction translation in a plane and rotate at the same time.
[0003] Due to the flexibility of Mecanum wheels, they can achieve true omnidirectional movement and quickly switch between different modes of movement. They are very suitable for handling materials, parts, and goods, especially in situations where the movement space requirements are high (narrow space or complex movement trajectory), such as crowded warehouses, the transfer of large parts, and precise adjustment of workpieces after they are transported to their destination.
[0004] However, most of the Mecanum wheel suspensions in the prior art are large and clumsy.
[0005] Therefore, it is necessary to provide a new Mecanum wheel vertical suspension to solve the above-mentioned technical problems. Utility Model Content
