Abstract

The invention discloses a two-speed front-end transmission structure. The structure comprises a transmission input shaft, a first clutch, a second clutch, a third clutch, a first input shaft gear, a second input shaft gear, a first intermediate shaft gear, a second intermediate shaft gear, a third intermediate shaft gear, a main speed reducer and a differential mechanism. The two-speed front-end transmission structure is provided, the other end of the transmission input shaft is provided with a motor for assisting an engine in work, and the power performance of an automobile can be greatly improved; three clutches are used for a gearbox, so that the gear shifting impact can be effectively eliminated, and the service life is longer compared with that of a traditional transmission which is shifted by a synchronizer; the gearbox is compact in structure and occupies less space inside the automobile; the gearbox is used for a hybrid electric automobile, and the economical efficiency of theautomobile can be greatly improved; and the transmission structure is simple, the machining process is simple, and the production cost is low.

Description

technical field [0001] The invention relates to the technical field of transmissions, in particular to a structure of a two-speed front drive transmission. Background technique [0002] At present, the transmissions that appear in the automobile market in our country are mainly multi-speed, manual or automatic, and only suitable for internal combustion engine-driven transmissions. This kind of transmission has many disadvantages, mainly reflected in: 1. The starting acceleration performance is poor; 2. The structure is complex, the production cost is high, and the space of a larger car is occupied; 3. The engine fuel consumption is high; 4. The engine is discharged Exhaust gas seriously pollutes the air. Contents of the invention [0003] The invention provides a two-speed front-drive transmission structure, the transmission is suitable for hybrid vehicles, its structure is simple, compact, low production cost, and the clutch is used instead of the traditional synchronize...
