Embodiment Construction

[0019] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0020] Such as figure 1 As shown, the present invention is made up of engine 1, ISG motor 10 and compound planetary gear mechanism three major parts. The compound planetary gear mechanism includes a first sun gear 2, a first planet gear 3, a planet carrier 4, a first outer ring 5, a second outer ring 6, a second planetary gear 7, a second sun gear 8 and a bull gear 9 . Wherein, the first sun gear 2 is fixedly sleeved on the output shaft of the engine 1, and the first sun gear 2 is located in the first outer ring 5, and the first outer ring 5 has its own locking mechanism, which can lock the first The outer ring 5 is locked or released, so that the first outer ring 5 can be fixed or rotated as required. The structure and working principle of the locking mechanism are prior art, and will not be repeated here.

[0021] Such as figure 1 As shown, between the...

Abstract

The invention discloses a hybrid power coupling mechanism. An output shaft of an engine (1) is fixedly sleeved with a first sun wheel (2), the first sun wheel (2) is meshed with a first outer ring (5) through first planet gears (3), all the first planet gears (3) are arranged on one end face of a planet carrier (4), second planet gears (7) are arranged on the other end face of the planet carrier (4), and all the second planet gears (7) are meshed with a second outer ring (6) and a second sun wheel (8); a big gear wheel (9) is coaxially fixed to the second sun wheel (8) and meshed with a pinion (11), and the pinion (11) is arranged on a main shaft of an ISG motor (10) in a sleeved mode. According to the hybrid power coupling mechanism, the optimum driving form under different working conditions can be achieved, power performance demands can be met, and fuel economy can be effectively improved; the hybrid power coupling mechanism has the advantages of being simple and compact in structure, small in size, easy to assemble, low in production cost, convenient to control, little in power loss, good in reliability, and the like.

Description

technical field [0001] The invention belongs to the technical field of power transmission, and in particular relates to a hybrid power coupling mechanism. Background technique [0002] In today's world, human beings are facing two major challenges: energy scarcity and environmental degradation. Traditional automobiles are increasingly plagued by the oil crisis. Electric vehicles have become the mainstream of industry development. Among them, hybrid electric vehicles are excellent in balancing economy and power, and have become the main development content of electric vehicles. The hybrid coupling mechanism directly determines the power distribution method and determines the power and economy of the vehicle. The existing hybrid coupling mechanism is generally composed of a set of planetary wheels + two clutches or two sets of planetary wheels + two clutches, which has complex structure, bulky size, difficult assembly, high production cost, inconvenient operation, and large p...
