Abstract

The invention relates to a double middle shaft transmission structure with hollow shaft synchronism and a shifting method thereof. The 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-shift middle shaft, the hollow input shaft is in transmission matching with an output shaft through an even-shift middle shaft, the hollow input shaft is sequentially sheathed with a fixing connecting synchronous gear of the hollow shaft and a fixing connecting gear of the hollow shaft from front end to tail end, the fixing connecting gear of the hollow shaft is respectively engaged with a hollow sheath synchronous gear of the odd-shift middle shaft and a fixing connecting gear of the even-shift middle shaft, the fixing connecting synchronous gear of the hollow shaft is engaged with the hollow sheath synchronous gear of the odd-shift middle shaft, the odd-shift middle shift is respectively in transmission matching with the hollow sheath synchronous gear of the odd-shift middle shaft and the hollow sheath gear of the odd-shift middle shaft through synchronous friction wheels, the fixing connecting gear of the odd-shift middle shaft is engaged with the fixing connecting gear of the solid input shaft, and the fixing connecting gear of the solid input shaft is sheathed on the solid input shaft. The structure has the advantages that the structure is simple, the arrangement space is little, the overhauling is convenient, and the production cost is low.

Description

technical field [0001] The invention relates to a gearbox synchronous structure, in particular to a hollow-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 ...
