Description

  The present invention generally relates to a transmission mechanism that can be independently controlled in series. More specifically, the energy input and the energy output can be variably utilized by using two planetary gear sets and two transmission connection sets that are located in series. The present invention relates to a transmission mechanism that can be controlled independently.

  As a conventional transmission mechanism, for example, Patent Document 1 proposes a vehicle transmission structure in which a slide is installed on a main shaft. A forward gear and a drive gear are installed on both sides of the slide, and a backward slide is installed on the interlocking shaft. A reverse bevel gear and a forward bevel gear are installed on the interlocking shaft located on the reverse slide side, and a final shaft that is transmitted by a shaft is installed between the reverse bevel gear and the forward bevel gear. . Positioning the final shaft between the reverse bevel gear and the forward bevel gear, and positioning the drive gear and the forward gear between the reverse bevel gear and the forward bevel gear; Reduce the width of. At the same time, the reverse bevel gear and the forward bevel gear of the interlocking shaft are engaged with the transmission bevel gear of the final shaft, thereby reducing the size of the transmission. However, since the slide that slides due to friction is installed in the transmission, the transmission efficiency is lowered.

  As another transmission mechanism, for example, Patent Document 2 proposes a continuously variable transmission set. The continuously variable transmission set includes a first planetary gear set and a second planetary gear set that are used to transfer the power of the first motor and the second motor to the transmission shaft. However, the continuously variable transmission set transfers the power of the first motor and the second motor to the transmission shaft via the first planetary gear set and the second planetary gear set in a fixed manner. In other words, in the continuously variable transmission set, the first motor and the second motor are fixedly set at two power input ends, and the transmission shaft is fixedly set at a single power output end. In short, in power transmission, there is a need to further provide a transmission mechanism that can variably control energy input and energy output in order to satisfy different power transmission requirements.

Accordingly, the present invention provides a transmission mechanism that can be independently controlled in series in order to improve the above-described drawbacks or satisfy the above-described requirements. The transmission mechanism variably controls energy input and energy output using two planetary gear sets and two transmission connection sets located in series. The transmission mechanism includes an energy output end, a control end, an energy input end, and a free transmission end. The control end controls the free transmission end to freely switch to an energy input end or an energy output end, and achieves the purpose of independently controlling transmission and increasing transmission efficiency. In addition, the said transmission mechanism can achieve the objective which improves a transmission efficiency, without using another friction sliding member.
