Abstract

A first clutch unit of a clutch mechanism (C) of the transmission comprises a one-way overrunning clutch assembly (2) capable of enabling a first gear (G1) as a gear to rotate along with a first shaft (S1) towards one side in the circumferential direction and a jaw meshing assembly (3) capable of enabling the first gear (G1) to rotate along with the first shaft (S1) towards at least one side in the circumferential direction. In the process of shifting through the transmission, the jaw meshing assembly (3) can be separated at the initial stage of the shifting process, the one-way overrunning clutch assembly (2) can ensure that the transmission still provides power in the shifting process, the power interruption phenomenon cannot be generated, the power interruption time is short, the shifting is stable, and in addition, the clutch mechanism (C) can still realize the shifting work under the condition of high rotational inertia.
