Six-gear hybrid transmission for hybrid electric vehicle and application method thereof

Abstract

The invention relates to a six-gear hybrid transmission for a hybrid electric vehicle and an application method thereof, which belong to the technical field of hybrid electric vehicle transmissions. The technical scheme is that the six-gear hybrid transmission for the hybrid electric vehicle comprises a No. 2 driving gear (12) and a No. 3 driving gear (11), a No. 1 driving gear (21), a M1 gear driven gear (34), a G1 gear driven gear (33), a G3 gear driven gear (32), a main speed reduction driving gear (31), a No. 2 synchronizer S2 and a No. 4 synchronizer S4, an M2 gear driven gear (44), a G2 gear driven gear (43), a G4 gear driven gear (42), a main speed reduction driving gear (41), a No. 1 synchronizer S1 and a No. 3 synchronizer S3 as well as a driving gear, wherein the No. 2 driving gear (12) and the No. 3 driving gear (11) are placed on an engine input shaft (10); the No. 1 driving gear (21) is placed on a motor EM1 input shaft (20); the M1 gear driven gear (34), the G1 gear driven gear (33), the G3 gear driven gear (32), the main speed reduction driving gear (31), the No. 2 synchronizer S2 and the No. 4 synchronizer S4 are placed on an output shaft I (30); the M2 gear driven gear (44), the G2 gear driven gear (43), the G4 gear driven gear (42), the main speed reduction driving gear (41), the No. 1 synchronizer S1 and the No. 3 synchronizer S3 are placed on an output shaft II (40); and the driving gear is placed on a motor EM2 input shaft (60). The six-gear hybrid transmission for the hybrid electric vehicle is advantaged in that the driving comfort and dynamic property are improved, the oil consumption of the hybrid vehicle is reduced and the exhaust emission is reduced.

Description

technical field [0001] The invention relates to a six-speed hybrid transmission for a hybrid electric vehicle and a method for using the same, belonging to the technical field of transmissions for hybrid electric vehicles. Background technique [0002] In recent years, due to the dual pressure of energy crisis and environmental pollution, countries have introduced relevant policies to guide and encourage the development and promotion of new energy vehicles. At present, among new energy vehicles in my country, hybrid vehicles are developing most rapidly. Hybrid generally refers to gasoline-electric hybrid. Hybrid vehicles have dual engines of motor and engine, which can be driven by the single power of the motor or the engine, or simultaneously driven by the motor and the engine. When the engine shifts gears, the motor provides power compensation, and when the motor shifts gears, the engine provides power compensation. It works normally. It will coordinate the power output ...

AI Technical Summary

Problems solved by technology

If the car is more driven by the electric motor during driving, if the electric motor drives the transmission input shaft, there will be no power compensation for gear shifting, resulting in poor driving comfort; if the electric motor drives the transmission output shaft, the transmission gear utilization rate will be low, resulting in waste

Therefore, the perfect match of power, economy and comfort cannot be achieved
