Abstract

The present invention provides a transmission, an upshift control method and device, and a downshift control method and device, which can solve the situation of power interruption in the conventional transmission during the shifting process. The transmission includes an input shaft, an intermediate shaft, a clutch, and a transmission device. , the driving gear assembly, the driven gear, the intermediate shaft, the meshing sleeve, and the synchronizer, the odd-numbered gear transmission device is respectively connected with the input shaft and the first connecting shaft of the clutch, and the even-numbered gear transmission device is respectively connected with the input shaft and the second connecting shaft of the clutch The connecting shaft is connected; the driving gear assembly is sleeved on the input shaft and connected with the transmission device through the driving gear; the driven gear is sleeved on the intermediate shaft, the driven gear is meshed with the driving gear through the gear pair, and the meshing sleeve is arranged on the input shaft to synchronize The device is arranged on the intermediate shaft; the gear transmission pair and the output shaft are respectively connected with the intermediate shaft and the output shaft.

Description

technical field [0001] The present invention relates to the technical field of transmissions, and in particular, to a transmission, an upshift control method and device, and a downshift control method and device. Background technique [0002] Mechanical automatic transmission (AMT: Automated Mechanical Transmission) is improved on the basis of traditional manual gear transmission. As an electromechanical-hydraulic integrated automatic transmission, it combines automatic transmission (AT: Automatic Transmission) and manual transmission ( MT: Manual Transmission) the advantages of both. It can be seen that AMT not only has the characteristics of automatic transmission of hydraulic automatic transmission. [0003] However, in a traditional vehicle with an AMT transmission, when the vehicle uses the AMT transmission to shift gears, due to the operation of the shifting clutch, there will be a power interruption during the shifting process, that is, the process of upshifting or d...
