Abstract

The invention provides a series-parallel double-planet-row two-mode hybrid electric automobile gearbox and relates to the technical field of automobiles. The gearbox comprises a front planet row, a rear planet row, a clutch, a brake, a motor system, a main reducer and a box body. Switching of different working modes is realized by controlling engagement and disengagement of the clutch and the brake. The grade ability of the automobiles can be improved during low-speed running. The transmission efficiency of the automobiles can be improved during high-speed running. The cost is lowered.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a gearbox for a mixed-connected dual-planetary dual-mode hybrid electric vehicle. Background technique [0002] As the main component of the power system, the gearbox of a hybrid hybrid electric vehicle must not only have basic functions such as speed adjustment, deceleration and torque increase, but also realize the power splitting of each power source. At present, the typical power split structure forms are Toyota's THS system and the general AHS system. Among them, Toyota's THS system is a single-mode power splitting form of a single planetary row, which has the advantages of simple structure and easy control. However, the THS system relies heavily on the motor, and it often needs to match a large power level to meet the power requirements. Therefore, there is a problem of low hardware utilization. At the same time, the THS system also has poor climbing ability at low spe...
