性能上好ましくなかつた。従つて従来では乗心地
を調整することができなかつた。 It is well known in the art to support cabs or axles with air bellows. However, in conventional air suspensions, the lower surface of the air bellows is fixed to a fixed surface and supported by the upper surface, so if the internal pressure of the air bellows is changed to adjust ride comfort, the overall height and posture of the vehicle will change. This was not desirable in terms of performance. Therefore, in the past, it was not possible to adjust the riding comfort.
本発明は、このような従来の問題点を解決した
エアサスペンシヨンを提供するものである。 The present invention provides an air suspension that solves these conventional problems.
以下本発明の実施例を図面に基いて説明する。 Embodiments of the present invention will be described below based on the drawings.

Air bellows 2a and 2b are disposed on both upper and lower surfaces of this support member 1. The upper surface of the upper air bellows 2a is fixed to the upper fixing surface 1a, and the lower surface of the lower air bellows 2b is fixed to the lower fixing surface 1b. Furthermore, the surge tank 3 and the upper and lower air bellows 2
Throttle valves 4a and 4b are provided in air pipes 3a and 3b that communicate with air pipes a and 2b. Furthermore, the throttle valve 4a,
4b may be manually controlled, but
It is also possible to automatically control the microcomputer 5 according to various conditions, and at the same time, the air pressure regulating valve 6 of the surge tank 3 can also be automatically controlled.

FIG. 2 shows a case in which a cab 8 is supported, and a support member 1 is fixed to the cab 8, and air bellows 2a and 2b are arranged on both upper and lower surfaces thereof.
The fixing means on the upper surface of the upper air bellows 2a abuts on a fixing member 7 fixed to the frame 9, and the lower surface of the lower air bellows 2a abuts on the frame 9.

ある。 Figures 3 and 4 show the body 11 and the axle 10.
This is a case where support is given. In this case, the support member 1 is fixed to the body 11, the air bellows 2a and 2b are arranged on both the upper and lower surfaces of the support member 1, and the upper surface of the upper air bellows 2a is fixed with the fixing member 7a fixed to the axle 10. , the lower surface of the lower air bellows 2b is fixed on the axle 10. FIG. 5 shows another design modification example in which the axle 10 is used as a support member, air bellows 2a and 2b are arranged on both upper and lower surfaces of the axle 10, and the upper surface of the upper air bellows 2a is a body 11.
The lower surface of the lower air bellows 2b is fixed on a fixing member 7a fixed to the body 11.

デイ１１の高さや姿勢が変化することがない。 Since the present invention has the above-described structure, the object to be elastically supported, that is, the cab 8 or the body 11, is supported by two upper and lower air bellows 2a, 2b.
It will be held at Furthermore, even if the internal pressure of the two upper and lower air bellows 2a and 2b is changed, the lower air bellows 2b tries to push up, but the upper air bellows 2a cannot be pushed downward because its upper surface is fixed. The height and posture of the cab 8 or the body 11 do not change.
従つて、エアベローズ２ａ，２ｂの内圧を絞り

ている。 As described above, the present invention provides a suspension using air bellows that is conventionally known, in which both upper and lower surfaces of a support member integrated with a movable body are supported by elastics with two upper and lower air bellows, and the upper surface of the upper air bellows is connected to the lower air bellows. It has a special arrangement structure in which the lower surface of the bellows is fixed to a fixed surface, and a throttle valve is provided in the piping path of each air bellows, so that the internal pressure of each air bellows can be freely adjusted.
This has the advantage that ride comfort can be adjusted, which was not possible in the past, without changing the overall height or posture of the vehicle.
