<p>A planetary gear mechanism includes an input sun gear assembly (1), at least one planet pinion assembly (2), a carrier assembly (4) and an output sun gear assembly (3). The input sun gear assembly (1), the carrier assembly (4) and the output sun gear assembly (3) have one common rotation axis, and any two of them can be rotated relative to one another. The carrier assembly (4) and/or the output sun gear assembly (3) can be fixed, and only one of them can be fixed, and any two of the input sun gear assembly (1), the carrier assembly (4) and the output sun gear assembly (3) can be locked relative to one another, wherein the fixation and the lock thereof can only be performed alternatively. The planet pinion assemblies (2) are rotatably installed on the carrier assembly (4) about its axis. Each planet pinion assembly (2) includes two planet pinions (21, 22), and the two planet pinions (21, 22) are connected together via a shaft to rotate coaxially and synchronistically. One of the two planet pinions (21, 22) is meshed with an input sun gear (11), the other is meshed with an output sun gear (31). The present invention also relates to a transmission including the planetary gear mechanism.</p> |
