Title:
TRANSMISSION AND TWO-SPEED ELECTRIC BRIDGE-BASED DRIVING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/226856
Kind Code:
A1
Abstract:
A transmission and a two-speed electric bridge-based driving system comprising the transmission. A first clutch unit of a clutch mechanism (C) of the transmission comprises a one-way overrunning clutch assembly (2) capable of causing a first gear (G1) serving as a shift gear to rotate with a first shaft (S1) towards a side in a circumferential direction and a jaw engagement assembly (3) capable of causing the first gear (G1) to rotate with the first shaft (S1) towards at least one side in the circumferential direction. During shifting performed by means of the transmission, the jaw engagement assembly (3) is separated at an initial stage of the shifting, and the one-way overrunning clutch assembly (2) ensures that the transmission still provides power during the shifting. Power interruption does not occur, or the duration of power interruption is relatively short, and the shifting is smooth. In addition, the clutch mechanism (C) can still achieve shifting even when the moment of inertia is high.
