摘要:
By providing two separate units (A, B) for actively opening and closing a door (1) of an automobile, safe and reliable door opening and closing operation may be acheived. The first unit (A) is operated to open the door in a normal way and closes the door to its not fully latched state while the second unit (B) completes the door closure operation by closing it to the fully latched state, thereby reducing the unfavourable influences arising from the impact which is otherwise unavoidable for complete closure of the door.
摘要:
In order to render an actuator which is capable of selectively operating two remotely arranged latches or the like devices (102,104) highly compact, the device is provided with a reversible motor, a reduction gear and an clutch arrangement which includes a solenoid coil. In some embodiments the clutch includes a two stage arrangement which perits a small power economical solenoid arrangement to be used. The invention further features the use of a compact reduction gear which includes two ring gears (126, 128) and stepped pinion gears (124).

摘要:
A centrifugal clutch comprises a clutch drum (4) loosely rotated relative to a rotary drive shaft (21) and provided with large inner diameter portions (43) and engaging protuberances (44) inwardly projecting from the large inner diameter portions (43); a clutch body (5) loosely fitted within the clutch drum (4), admitting insertion and fitting of the rotary drive shaft (21) to be driven by the rotary drive shaft (21), and provided with a retaining hole (53) opening radially from the centre thereof toward the inner wall of the clutch drum (4); and an engaging permanent magnet (6) loosely movably retained in the retaining hole (53) of the clutch body. When the clutch body (5) is in a standstill state, the engaging permanent magnet (6) exerts its magnetic attraction onto the rotary drive shaft (21) and thereby is accommodated within the retaining hole (53). When the clutch body (5) continues its rotation, centrifugal force is generated. The centrifugal force allows the engaging permanent magnet (6) to protrude from the retaining hole (53), come into contact with the slide on the inner wall of the clutch drum (4) and engage with one of the engaging protuberances (44) of the clutch drum (4).
