The invention provides a novel multi-gear transmission and belongs to the technical field of transmissions. The novel multi-gear transmission solves the problems that an existing multi-gear transmission is complicated in structure and large in manufacturing difficulty. The novel multi-gear transmission comprises an input shaft, a middle shaft and output shaft, wherein the middle shaft is parallelto the input shaft, the output shaft and the input shaft are coaxially arranged, a reverse gear structure, a first first-grade speed reduction structure, a second first-grade speed reduction structure, a third first-grade speed reduction structure, a fourth first-grade speed reduction structure are sequentially arranged between the input shaft and the middle shaft, a first second-grade speed reduction structure and a second second-grade speed reduction structure are arranged between the middle shaft and the output shaft, a first synchronous structure is arranged between the first second-gradespeed reduction structure and the second second-grade speed reduction structure, a second synchronous structure is arranged between the fourth first-grade speed reduction structure and the first second-grade speed reduction structure, a third synchronous structure is arranged between the second first-grade speed reduction structure and the third first-grade speed reduction structure, and a fourthsynchronous structure is arranged between the reverse gear structure and the first first-grade speed reduction structure. The novel multi-gear transmission has the advantages of being simple and compact in structure, low in cost and the like.
