Abstract
The invention relates to an arrangement structure of a gear shaft system of a gearbox. The arrangement structure comprises an input shaft as well as first and second output shafts which are in parallel with the input shaft and are arranged at the two sides of the input shaft, wherein a four-speed driven gear on the first output shaft and a five-speed driven gear on the second output shaft are simultaneously meshed with a four-five-speed driving gear on the input shaft; and a two-speed driven gear on the second output shaft and a three-speed driven gear on the first output shaft are simultaneously meshed with a two-three-speed driving gear. The individual reverse gear shaft is not used in the arrangement structure. The reverse gear speed ratio is jointly realized by a pair of reverse gear sets and a pair of six-speed gear sets. A driving reverse gear and a six-speed driven gear are designed as a whole to form a duplicate gear to be sleeved on the second output shaft in an idle manner. A driven reverse gear is sleeved on the first output shaft in an idle manner. In the structure, the four driven gears share the two driving gears and the two adjacent gears share one driving gear. The arrangement structure has the following beneficial effects: the gearbox has a concise and compact structure; the precise gear speed ratio is easy to realize; the inner space is reasonable in arrangement; and the joint devices have a large arrangement space.
