PROBLEM TO BE SOLVED: To provide an electromagnetic suspension device having improved vibration suppressing performance by accurately transmitting an impelling force and a damping force in a high-frequency range to a sprung member. SOLUTION: An outer yoke 16A of an electromagnetic linear motor 2B is directly connected to an upper mount 11 of a vehicle body 10. Since the impelling force and the damping force of the electromagnetic linear motor 2B are directly transmitted to the vehicle body 10 side, the impelling force and the damping force in the high-frequency range can be effectively and accurately transmitted to the vehicle body 10 side, and the vibration suppressing performance is improved. Since the outer yoke 16A is touching to the outside air and a coil 15 is efficiently cooled even though the device has an air spring device 4B, vibration isolation and suppression of the attitude change of the vehicle body can be more improved by increasing the impelling force by making a large current flow. The heat generated by the electromagnetic linear motor 2A is prevented from transmitting to the hydraulic damper 3 as the direct contact is suppressed. Therefore, the hydraulic damper 3 brings out the regular characteristics of the damping force. COPYRIGHT: (C)2004,JPO |
