Abstract

The invention relates to a hybrid four-shaft transmission device, which comprises an outer gear ring, a planet carrier, a planet row and sun gears and is characterized in that: the planet row has a double-planet row structure consisting of a front planet row and a back planet row; the front planet row and the back planet row correspond to a sun gear respectively; a front row of planetary gears have small tooth widths and large reference circles; a back row of planetary gears have large tooth widths and small reference circles; the front row of planetary gears are meshed with the outer gear ring and a small sun gear so as to form a front row gear train; and the back row of planetary gears are meshed with the front row of planet gears and a large sun gear so as to form a back row gear train. A double-planet row four-shaft transmission device with a large transmission ratio between the sun gear of the back row gear train and the outer gear ring is realized.

Description

technical field [0001] The invention relates to a hybrid electric vehicle, in particular to a hybrid electric output power balancing device and a control method thereof. Background technique [0002] An existing double-star row four-shaft hybrid power transmission device, the small sun gear is connected with the generator E1, the big sun gear is connected with the motor E2, the engine is connected with the planetary carrier, and the driving half shaft passes through the differential, decelerates The device is connected with the outer ring gear. The whole vehicle control system achieves: 1) optimizing and adjusting the output power of the engine by coordinating the control of the generator E1 and the electric motor E2, and maximizing the efficiency of the entire hybrid system and reducing the fuel consumption of the whole vehicle on the premise of meeting the driving performance requirements of the driver ; 2) Balance the charging and discharging power of the battery, protec...
