In an active suspension system, an electromagnetic actuator is interposed between a tube connected to a vehicle body and a rod connected to a wheel. The electromagnetic actuator includes a motor vertically slidably accommodated within the tube and supported in a floating manner by motor supporting springs, and a ball screw driven by the motor. The displacement between the vehicle body and the wheel and the load are controlled by driving the ball screw by the motor. When a fierce load is applied from the wheel, the motor itself resiliently moves upwardly while compressing one of the motor supporting springs, thereby permitting the upward movement of the rod to prevent the locking of the active suspension system, leading to an enhanced riding comfort.
An active suspension system comprising an electromagnetic actuator which is disposed between a wheel and a vehicle body and which comprises a screw means having externally and internally threaded members meshed with each other, and a motor for driving said screw means in an expanding and contracting manner in response to external forces acting on the wheel and the vehicle body while traveling, wherein at least one of said motor and said screw means is resiliently supported on at least one of said wheel and said vehicle body through a spring means.
An active suspension system comprising an electromagnetic actuator which is disposed between a wheel and a vehicle body and which comprises a screw means having externally and internally threaded members meshed with each other, and a motor for driving said screw means in an expanding and contracting manner, wherein at least one of said motor and said screw means is resiliently supported on at least one of said wheel and said vehicle body through a spring means;
