Abstract

The invention discloses a dual-countershaft transmission structure with a synchronous solid shaft and a shifting method of the dual-countershaft transmission structure. The dual-countershaft transmission structure comprises a solid input shaft and a hollow input shaft, wherein the solid input shaft is in transmission matching with an output shaft through an odd-gear countershaft, the hollow input shaft is in transmission matching with the output shaft through an even-gear countershaft, the solid input shaft is sequentially sleeved with a solid shaft fixed connecting synchronous gear and a solid shaft fixed connecting gear from the first end to the tail end, the solid shaft fixed connecting gear is respectively meshed with an odd-gear countershaft fixed connecting gear and an even-gear countershaft hollow sleeve gear, the solid shaft fixed connecting synchronous gear is meshed with an even-gear countershaft hollow sleeve synchronous gear, the even-gear countershaft is respectively in transmission matching with the even-gear countershaft hollow sleeve synchronous gear and the even-gear countershaft hollow sleeve gear through a synchronous friction wheel, and the even-gear countershaft fixed connecting gear is meshed with a hollow shaft fixed connecting gear on the hollow input shaft. According to the dual-countershaft transmission structure disclosed by the invention, the structure is simple, the arrangement space is small, the maintenance is convenient, and the production cost is low.

Description

technical field [0001] The invention relates to a gearbox synchronous structure, in particular to a solid-shaft synchronous double countershaft transmission structure and a shifting method thereof, which are particularly suitable for simplifying the gearbox structure, optimizing the shifting mode, and reducing production costs. Background technique [0002] The dual-clutch transmission enables the vehicle to automatically shift gears without power interruption, which not only makes the driving of the car easier, but also effectively improves the comfort, power and safety of the car. [0003] The Chinese patent application publication number is CN103032528A, and the application publication date is April 10, 2013. The invention patent discloses a double intermediate shaft DCT structure and its gear ratio calculation method, including double clutches, solid input shafts and hollow input shafts. One end of the coaxially arranged solid input shaft and the hollow input shaft are c...
