Double clutch gearbox and double clutch speed change method

Abstract

The invention provides a double clutch gearbox and a double clutch speed change method. The double clutch gearbox comprises a motor, an input shaft, an intermediate shaft, an output shaft, a first-gear clutch assembly, a second-gear clutch assembly, a first-gear driving gear, a first-gear driven gear, a second-gear driving gear, a second-gear driven gear, a main speed reducer driving gear, main speed reducer driven gear, a differential mechanism assembly, a clutch sleeve and a gear shifting pull rod; the first-gear clutch assembly comprises a first-gear clutch shifting fork, a first-gear clutch driving disc and a first-gear clutch driven disc; and the second-gear clutch assembly comprises a second-gear clutch shifting fork, a second-gear clutch driving disc and a second-gear clutch drivendisc. The double clutch gearbox has the advantages that 1, gear shifting is easy, and gear shifting can be achieved only by operating the gear shifting pull rod; 2, power is not interrupted during gear shifting, a motor continues working, and gear shifting is smooth and free of impact; 3, the double clutch efficiency is high, and the service life is long; and the size is small, the weight is low,and arrangement is facilitated.

Description

technical field [0001] The invention belongs to the technical field of gearboxes, and in particular relates to a dual-clutch gearbox and a dual-clutch transmission method. Background technique [0002] The gearbox is the core component of the engine field. At this stage, when an electric vehicle changes gears, it needs to stop and change gears, that is, the power needs to be interrupted first, and then the gear shifting operation can be realized, which affects the driving experience. Contents of the invention [0003] Aiming at the defects in the prior art, the present invention provides a dual-clutch gearbox and a dual-clutch transmission method, which can effectively solve the above problems. [0004] The technical scheme that the present invention adopts is as follows: [0005] The present invention provides 1. A dual-clutch gearbox, which is characterized in that it comprises: a motor (1), an input shaft (2), an intermediate shaft (3), an output shaft (4), a first-spe...
