本ＪｉＱＱはエアサスペンション車におけるクロスメン
バ構造に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present JiQQ relates to a cross member structure in an air suspension vehicle.
自動車の車輪懸架装置に、封入されたエアの容積弾性を
利用するエアダンパを用いた所謂エアサスペンション車
においては、該エアダンパのエア封入部にエアを供給す

上記のような車高調整を的確に行う為にはかなり大型の
エアタンクが必要であり、その大型のエアタンクの設置
スペースが問題となる。In a so-called air suspension vehicle that uses an air damper that utilizes the volumetric elasticity of sealed air in the wheel suspension system of a car, air is supplied to the air sealed portion of the air damper to raise the vehicle height and release the sealed air. By discharging it, the vehicle height can be lowered.
In order to accurately adjust the vehicle height as described above, a fairly large air tank is required, and the installation space for such a large air tank becomes a problem.

大型エアタンクの設置スペースの問題をも解消させたも
ので、以下本発明を附図実施例につき説明する。The present invention utilizes a hollow cross member to which a suspension arm supporting a wheel is rotatably attached, and uses the cross member as an air tank for adjusting the vehicle height of an air suspension, thereby eliminating the need for a dedicated large air tank. This invention also solves the problem of installation space for the large air tank, and the present invention will be explained below with reference to the accompanying drawings.

弾力支持するよう構成される。In the figure, reference numeral 1 denotes a hollow cylindrical cross member, and an outer arm 2 and an inner arm 3 are connected to a shaft 22 t through elastic bushings 21 and 31 made of rubber or the like, respectively.
, 32, and a wheel 4 is rotatably supported at the tip of a suspension arm consisting of the outer arm 1 and the inner arm 3, and an air damper 5 is interposed between the suspension arm and a vehicle body structural member (not shown). The air damper 5 is configured to elastically support the swinging of the suspension arm due to the vertical movement of the wheel 4.

成される。The cross member 1 is attached by fixing brackets 6 fixed to both sides of the cross member 1 to a vehicle body structural member 7 such as a frame with bolts or the like via an elastic material 8 such as rubber. The elastic material 8 absorbs and reduces the transmission of load to the vehicle body structural member T.

を下げるようＫなっている。An inlet/outlet pipe 11 having a tank pulp TV is connected to the inlet/outlet 9, and when the air pressure in the cross member 1 becomes less than a predetermined value, a near compressor 12 is driven by a signal from a pressure switch 10, and a tank pulp TV is connected to the inlet/outlet pipe 11.
opens to supply air into the cross member 1 to maintain the air pressure in the cross member 1 within a predetermined value range, and the front and rear air dampers 5F and 5RK70 valves FV and rear pulp RV are installed in the inlet/outlet piping 11. For example, when the air pressure of each air damper decreases and the vehicle height decreases, the tank pulp TV opens due to a signal from a vehicle height sensor (not shown), and at the same time the front pulp FV or When the valve RV or both open, the air stored in the cross member 1 is supplied to a designated air damper to raise the vehicle height, and when a signal to lower the vehicle height is issued, the front pulp F
At the same time when V or rear valve RV or both open, exhaust valve EV opens and exhausts air in the air damper to the outside to lower the vehicle height.

ヤである。In the top view, Cv is cut pulp, which prevents the air damper tg-xa from flowing from one of the left and right air dampers to the other and causing the left and right balance to collapse when the car body rolls on a curve etc. It is an air trill.
以上のように本発明によれば、クロスメンバラエアサス

。As described above, according to the present invention, by adopting a configuration in which air is used as a tank for adjusting the vehicle height of the cross member air suspension, a dedicated large air tank can be omitted, resulting in significant weight and cost reductions. The only benefit is that there is no need for a large air tank installation space.
It can bring about extremely excellent effects.

供給すべきエアダンパまでの距離が非常に近くエア配管
が楽になる等実用上長くの効果をもたらし得る。Although any cross member can be used as the air tank, if the cross member that constitutes the suspension assembly to which the wheel suspension arm is rotatably attached as in the illustrated embodiment is used as the air tank, it can be used to create an airtight seal, an air inlet/outlet, and a breather switch. Since the installation port etc. can be configured at the component stage, the work is extremely easy, and even more air-free.
The distance to the air damper to be supplied is very short, making air piping easier, and can bring about long-lasting effects in practical terms.
