駐車メカニズム、ＥＭＢシステム、及び車両

Japanese Patent JP7371176

B2

This application provides a parking mechanism, an electronic mechanical brake (EMB) system, and a vehicle. The parking mechanism may be integrated into an EMB system of the vehicle to brake the vehicle to standstill. The parking mechanism includes a wheel disc (1), a wedge disc (2), and a drive assembly (3). An axis of the wheel disc and an axis of the wedge disc both are aligned with an axis of a motor shaft. A wedge groove (21) with an opening facing the wheel disc is formed on a surface of the wedge disc facing the wheel disc, and a movable part (22) in contact with the wheel disc is disposed in the wedge groove. In a direction from a bottom of the wedge groove to the wheel disc, a groove depth at a first end of the wedge groove is greater than a size of the movable part, and a groove depth at a second end of the wedge groove is less than the size of the movable part. An elastic part (23) is disposed between the movable part and the first end of the wedge groove, and the elastic part has a trend of driving the movable part to move from the first end to the second end of the wedge groove. The drive assembly is configured to drive the movable part to move from the second end to the first end of the wedge groove. The parking mechanism can provide stepless variable parking force. This can implement unidirectional locking of the motor shaft when the parking force increases.
