Abstract

The invention specifically relates to a hybrid multi-gear gearbox, which belongs to the technical field of vehicle transmission. A power gear-shifting hybrid gearbox for a commercial vehicle comprises an engine (101), a clutch (103), a motor (102) and a gearbox (104). The technical scheme of the power gear-shifting hybrid gearbox for the commercial vehicle is that the power of the engine (101) is input into an engine output shaft (301) after passing through the clutch (103); and the power of the motor (102) is input into a motor input shaft (305). The gearbox (104) comprises a plurality of free fixed-axle gear mechanisms, which can couple powers of the engine (101) and the motor (102) and can realize 8 gears matched with the engine, and 3 gears matched with the motor. According to the invention, power gear shifting and hybrid power working condition can be realized; vehicle power performance can be improved; gear shifting quality can be improved; clutch abrasion can be reduced; and fuel efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle transmission, and in particular relates to a hybrid multi-speed gearbox. Background technique [0002] Hybrid technology has the advantages of reducing emissions and fuel consumption, and at the same time improves vehicle dynamic performance, which has become the development direction of future automotive power transmission technology. The advantages of parallel hybrid power are: the power of the engine can be directly used to drive the vehicle without energy conversion, the energy loss is small, and the structure is simple; the motor can be used as a motor or a generator, and a smaller power can be used The motor has simple structure and low cost. In the parallel hybrid technology, the motor mainly realizes the power assist under the rapid acceleration condition or the low-speed engine condition, improves the power performance, and improves the fuel economy of the engine; in the deceleration con...
