Problems solved by technology

[0002] The pure gear automatic transmission currently used in the field of power machinery transmission is adopted by mechanical equipment with high economic value due to its advantages such as stable speed change, low noise, high transmission efficiency, and long service life, but the pure gear continuously variable transmission has always been unable to solve the problem. The control mechanism is complex, difficult to process and produce, resulting in high cost, inconvenient maintenance and many other troubles
Steel chain and belt-type automatic continuously variable transmissions, although they have automatic continuously variable transmission performance, but their service life is short, compared with pure gear automatic transmissions, the wear and tear is relatively large, and the transmission stability is reduced by the increase in the service cycle. Pure gear automatic transmission, steel chain type and belt type automatic continuously variable transmission have the above-mentioned shortcomings, which is the fundamental reason why it is still difficult to be popularized and applied

Embodiment 1

[0033] like figure 1 As shown, the responsive automatic continuously variable transmission device of the present invention includes a pre-disassembly mechanism, a multi-functional linkage mechanism, a booster and a speed regulation mechanism.

[0034] The front decomposition mechanism includes a front planetary carrier 1, a front ring gear and an intermediate sun gear assembly 2, and a front and rear sun gear assembly 3. The front planetary carrier 1 includes a front planetary gear 11 and a front planetary carrier 12 supporting the front planetary gear 11, The front ring gear and middle sun gear assembly 2 includes a front ring gear 21 and a middle sun gear 22. The front and rear sun gear assemblies 3 include a front sun gear 31 and a rear sun gear 32. The outer diameter of the front sun gear 31 is greater than or equal to that of the rear sun gear. 32 OD.

[0035] The multifunctional linkage mechanism includes a multifunctional planet carrier assembly 4, a rear double ring g...

Embodiment 2

[0052] like figure 2As shown, the responsive automatic continuously variable transmission device of the present invention is an automatic continuously variable transmission device designed to meet the required heavy and light working conditions of motor vehicles, and is also suitable for high-speed stamping, hydraulic pressure, lifting, etc. equipment. It differs from the first embodiment above in that its central planetary gear 41 is a double gear, and the double gear includes a central small planetary gear 411 and a central large planetary gear 412, and the central large planetary gear in the central planetary gear 41 The gear 412 meshes with the central sun gear 22 and the central large ring gear 414 respectively, and the central small planetary gear 411 of the central planetary gear 41 meshes with the central small ring gear 413 . The central small ring gear 413 is provided with a one-way device IIF2 for cooperating with limiting the reverse rotation of the central small...

Embodiment 3

[0055] like image 3 As shown, the responsive automatic continuously variable transmission device of the present invention differs from the first embodiment above in that: the front ring gear 21 is connected with the multifunctional planetary carrier 44, and the combination is connected to form the front ring gear and the multifunctional planetary carrier assembly 23, namely The pre-disassembly mechanism and the multifunctional linkage mechanism share the front ring gear 21 and the multifunctional planetary carrier 44, which is only a simplified form of Embodiment 1, and the power of the A road is directly transmitted to the multifunctional planetary carrier 44. Other structures and working principles Same as the first embodiment, it has the advantage of effectively saving axial space. It is suitable for those that require low speed but do not require high speed: such as bicycles, hydraulic lifting machinery and other tools or equipment.
