摘要:
An electro-mechanical actuator (1) including a plurality of motors (2, 3) for driving an output shaft (10). The actuator may be incorporated into a window lift mechanism (30), such as a mechanism including a dual rack and pinion assembly (1314). According to another aspect of the invention there is provided a variety of anti-back-drive mechanisms, e.g. clutches. A clutch according to one embodiment includes locking pawls (1616, 1618) that resist back-drive. In another embodiment, locking cams (2108) rotate relative to a carrier (2106) to resist back-drive. An actuator consistent with the invention may incorporate an impact mechanism (2616) including a flexible carrier (2618). The carrier (2106) flexes to prevent impact forces at an output gear train (2610, 2612) from coupling to an input gear train (2604, 2606).
摘要:
An electro-mechanical actuator (100) including a motor (104) for driving an actuator output shaft (126) through a gear train and a drive belt (112) for coupling torque from the motor (104) to the gear train. In one embodiment, elastomeric motor supports (130) are provided between the motor (104) and an actuator housing (102).
