えば第3図のようになる。If the road surface (4) is uneven, the tires (3)
The axle (2) vibrates up and down, and this vibration is transmitted to the vehicle body (1) via the shock absorber (5) and coil spring (6).
). At this time, the response characteristic of the vibration of the vehicle body (1) to the vibration frequency f due to the unevenness of the road surface <4> is as shown in FIG. 3, for example.

である。In Fig. 3, the vertical axis is the amplitude ratio R with respect to the vehicle body (1> road surface 4), and the horizontal axis is the road surface (4), that is, the tire (3>
is the vibration frequency f of the side. The dashed line, solid line, and dashed-dotted line are characteristic curves when the damping force of shock absorber <5> is changed.The dashed line shows the case where the damping force is small, the solid line shows the case where it is intermediate, and the dashed-dotted line shows the case where it is large. . Further, f is the resonance frequency of the spring 2, ie, the vehicle body (1) side, f2 is the resonance frequency of the bottom of the spring, ie, the tire (3) side, and A is the human discomfort range.
第3図から、ショックアブソーバ〈5〉の減衰力に関し

あるため、乗り心地が悪くなる。(When the IBM damping force is small, the response in the discomfort band A decreases as shown by the broken line, but the resonance frequency f of the vehicle body (1)
, the amplitude is large. Therefore, when the vehicle runs over an obstacle such as a protrusion on the road surface (4), the vibrations do not converge and become unstable, resulting in poor ride comfort.
(II)減衰力が大きい場合は、共振周波数f、及びf
、のような共振点がほとんどなくなり、振動の収束性も
良くなるが、不快感帯域Aでの応答性が増加するため、
やはり乗り心地が悪くなってしまう。(II) If the damping force is large, the resonance frequency f and f
There are almost no resonance points such as , and the vibration convergence is improved, but the response in the discomfort band A increases.
After all, the ride becomes uncomfortable.
従って、乗り心地及び安定性の両面から妥協して、減衰
力は、実線のように、(1)及び(1■)の中間に設定
されている。Therefore, as a compromise in terms of ride comfort and stability, the damping force is set between (1) and (1), as shown by the solid line.
次に、コイルバネ(6)の強さについて考慮する。Next, consider the strength of the coil spring (6).

ある。しかし、バネ係数kを大きくすると、車体(1)
側の共振周波数f、がシフI・して不快感帯域Aに近づ
くため乗り心地が悪くなる。For example, pitching moment force due to braking and acceleration, and rolling moment force due to turning are:
This acts as a force acting on the car body (1), but in order to counter this and keep the attitude angle of the car body (1) constant, a coil spring (
6) must be made somewhat stiff (increase the spring coefficient k).However, if the spring coefficient k is increased, the car body (1)
The side resonant frequency f shifts to I and approaches the discomfort band A, resulting in poor ride comfort.

ある。To solve this problem of ride quality, coil springs (6)
In addition to reducing the spring coefficient k of the shock absorber (
5) so that the damping force follows the lowest line in Figure 3, vibration frequency f<discomfort band A→damping force large vibration frequency f-
Discomfort band A-=damping force small vibration frequency f> Discomfort band A
→It is necessary to set the damping force to medium. However, it is difficult to vary the damping force according to the region of the vibration frequency f due to the characteristics of the shock absorber (5) that uses hydraulic pressure.

という問題点がある。Also, if the strength of the coil spring (6) is lowered, the car body (
It is necessary to prepare another measure to stabilize the posture of 1). For this reason, for example, it may be possible to use a known air spring or the like instead of the coil spring (6) and control the spring coefficient k by the intake IJF air, but there is a problem that the response is poor.

点がある。Furthermore, the shock absorber (5) is replaced with a hydraulic actuator, and an elastic body is provided in parallel with the hydraulic actuator, so that the position of the vehicle body (1) follows the target vehicle height while reducing vibrations from the lower suspension member, that is, the axle (2). For this purpose, a method may be considered in which the thrust of the hydraulic actuator is controlled so as not to cancel the restoring force of the coil spring (6). However, although the hydraulic actuator has better responsiveness than the pneumatic actuator, there is a problem in that high-speed control is required because vibrations are directly transmitted due to the incompressibility of the liquid.

うに安定に支持される。If the road surface (4) on which the vehicle is running is very uneven, the tires (
Since the vibration frequency f of the vehicle body (1) transmitted from the linear motor (10) is high, the linear motor (10) is in the vibration isolation mode, and the supply current i from the drive circuit (34) is constant. At this time, the linear motor (10) is controlled to have a constant thrust, and even if high-frequency vibrations higher than a predetermined frequency are transmitted from the road surface (4) to the unsprung member (3a), the vehicle body <1> is not transmitted. As a result, the vehicle body (1) does not follow high frequency vibrations at all, and is stably supported so that the absolute vehicle height is constant.

determines the supply current i to the linear motor (10). As a result, the linear motor (10) is in a mode that follows the undulation vibration, and the vehicle body (1) is supported so as not to resonate with the undulation.

アモータ(10)の消費電力は著し、く節減される。Generally, the linear motor (10) generates thrust by spatial electromagnetic action, and this thrust does not depend on the slide position, so the unsprung member <3a> and the sprung member (1a)
) The supporting force does not change depending on the amount of displacement. Therefore, it has the characteristic that high frequency vibrations are not transmitted at all, and since it is controlled by switching between the thrust force and the supply current i, the response is extremely good, and the following control of the vehicle body (1) and the absolute vehicle height Both constant control and constant control are possible.As a result, it is possible to realize an automobile suspension system with extremely excellent high-frequency vibration isolation properties and high absolute vehicle height stability ability for the vehicle body (1). With the vehicle height tracking mode, it is possible to realize an automobile suspension system with excellent posture controllability.Furthermore, since most of the mass of the vehicle body (1) is supported by the coil IL spring (6), the linear motor The power consumption of (10) is significantly reduced.
