Document Type and Number:
WIPO Patent Application WO/2021/115374
Kind Code:
A1
Abstract:
A power assembly, a drive system and an automobile, belonging to the technical field of automobile driving. The power assembly comprises: a drive motor (1), a gear mechanism (2), a left half shaft (3), a right half shaft (4), a differential (5), a clutch (6) and a clutch control assembly (7); an output shaft of the drive motor (1) is connected to the gear mechanism (2), and the gear mechanism (2) is mounted on the differential (5) by means of a bearing (8); the left half shaft (3) is connected to a left gear in the differential (5), and the right half shaft (4) is connected to a right gear in the differential (5); a driving disc (61) of the clutch (6) is located between the gear mechanism (2) and the differential (5), is fixedly mounted on the gear mechanism (2) and is sleeved on the differential (5), and a driven disc (62) of the clutch (6) is slidably sleeved on the differential (5); and the clutch control assembly (7) is mounted on the driven disc (62), and is used to control the driven disc (62) to slide on the differential (5) in a direction close to the driving disc (61), so that the driven disc (62) is combined with the driving disc (61), and to control the driven disc (62) to slide on the differential (5) in a direction away from the driving disc (61), so that the driven disc (62) is separated from the driving disc (61). Thereby, the driving effect of the power assembly can be improved.
