Problems solved by technology

[0002] The pure gear continuously variable transmission used in the industry at present, its speed change transmission effect is many steel chain type, belt type, etc. Many continuously variable transmissions cannot achieve the best speed change transmission mode. For a long time, due to the speed change and control of the pure gear continuously variable transmission The device is too complicated, causing many difficulties in manufacturing, maintenance and other work, so the cost of production and use is too high, which restricts the popularization and promotion of gear CVT

Embodiment 2

[0037] Embodiment two: figure 2 Shown is the second embodiment of the speed differential dual-drive compound continuously variable transmission method of the present invention, which is different from the first embodiment above in that the front planetary gear 11 of the front resolution mechanism 1 is a single gear. The planetary gear on the pre-decomposition mechanism adopts a single gear, so that the power of the pre-decomposition mechanism can be decomposed symmetrically and in the same direction. The front-end input power of the power of the A road and the power of the B road is equal. For the front planetary gear 11 of the front disassembly mechanism 1 meshes with the front ring gear 21, a part of the power of the front disassembly mechanism 1 is transmitted to the rear planet of the rear composite mechanism 4 through the front ring gear 21 and the rear ring gear 22 The pinion 411 of the gear. The specific transmission route of the B-way power is that the front planetar...

Embodiment 3

[0038] Embodiment three: image 3 Shown is the third embodiment of the speed differential dual-drive compound stepless speed change method of the present invention, which differs from the first embodiment in that the rear planetary gear of the rear compound mechanism 4 is a single gear 41, and the front decomposition mechanism The power is decomposed into A-way power and B-way power in the same direction. The specific transmission route of the A-way power is that the pinion 111 of the front planetary gear of the front disassembly mechanism 1 meshes with the front ring gear 21, and the front disassembly mechanism Part of the power of 1 is transmitted from the front ring gear 21 to the rear planetary gear 41 of the rear compound mechanism 4 through the rear ring gear 22 . The specific transmission route of the B-way power is that the large gear 112 in the planetary gear of the front disassembly mechanism 1 meshes with the front sun gear 31, and another part of the power of the f...
