Abstract

The invention provides a speed transmission and a two-gear electric-bridge driving system. A clutch mechanism of the speed transmission comprises a one-way clutch unit which enables an actuating assembly to be alternatively actuated to realize connection / separation and a friction dual-directional clutch unit which can realize separation / connection, wherein the one-way clutch unit corresponds to a first gear and the dual-directional clutch corresponds to a second gear, and thus, power interruption phenomenon is avoided in a process of changing gears of the clutch mechanism and the gears can be changed stably; and in addition, the clutch mechanism still can realize gear changing operation under the situation of higher rotation inertia.

Description

technical field [0001] The invention relates to the field of vehicles, more specifically to a transmission for a vehicle and a two-gear bridge drive system including the transmission. Background technique [0002] Existing transmissions used in two-speed transaxle drive systems such as hybrid vehicles often employ conventional synchronizers for shifting. Although the synchronizer can meet the shifting requirements of the transmission, there may be the following defects when using the synchronizer to shift gears: [0003] 1. Power interruption may occur during the shifting process; [0004] 2. The shifting process is not smooth; and [0005] 3. Only when the moment of inertia is low can shifting be realized. Contents of the invention [0006] The present invention is made in view of the above-mentioned defects of the two-speed bridge drive system. It is an object of the present invention to provide a transmission which avoids power interruptions and which is smooth duri...
