Problems solved by technology
[0010] However, the power splitting hybrid electric drive device in the prior art has the following problems: the structural characteristic parameter of the splitting planetary row 6 is 2.6, and the existing splitting planetary row 6 cannot be completely embedded in the first motor 2 and the second The inner cavity of the motor 3 still occupies a certain space in the axial direction, and the addition of two coaxially arranged motors makes the axial length of the hybrid power device still relatively large

The invention provides a hybrid electric driving device, and belongs to the technical field of vehicle driving. The device comprises an engine, a first motor, a second motor, a first planet row, a second planet row and wheels. The first planet row comprises a first sun gear, a first planet carrier and a first gear ring. The second planet row comprises a second sun gear, a second planet carrier and a second gear ring. The engine is connected with the first planet carrier. The first motor is connected with the first sun gear. The first planet carrier is connected with the second sun gear. The first gear ring is connected with the second gear ring. The second planet carrier is connected with the wheels through the second motor. According to the hybrid electric driving device, the two planet rows are arranged, the two planet rows can be completely embedded into inner cavities of the two motors, and therefore the hybrid electric driving device with the compact axial length is obtained.
Description
technical field [0001] The invention relates to the technical field of vehicle drive, in particular to the technical field of vehicle hybrid drive, and in particular to a hybrid electric drive device. Background technique [0002] Such as figure 1 As shown, the existing power-split hybrid electric drive device includes an engine 1 , a first motor 2 , a second motor 3 , a split planetary row 6 and wheels 7 . Wherein, the distribution planet row 6 includes a sun gear 61 , a planet carrier 62 and a ring gear 63 . The engine 1 is connected with the planet carrier 62 of the distribution planetary row 6, the first motor 2 is connected with the sun gear 61 of the distribution planetary row 6, and the ring gear 62 of the distribution planetary row 6 is connected with the second motor 3 to drive the wheel 7, The power of the engine 1 is split into two paths through the planetary row 6, one path of power drives the first generator to generate electricity and supplies it to the secon...
