<p>A suspension gear decelerator and suspension gear zero-crossing multi-speed transmission, both comprising: a front planetary gear train, a rear planetary gear train and a suspension gear (1); different design of the sizes of the gears included in the front planetary gear train, the rear planetary gear train and the suspension gear can achieve any different reduction ratios. The suspension gear decelerator and the suspension gear zero-cross multi-speed transmission have simple structures and high reliability, and overcome the defect in the prior art of requiring a multi-speed gear transmission mechanism to achieve a high reduction ratio, thus reducing the overall size and lowering costs.</p> |
