Abstract

PURPOSE:To facilitate the assembling and adjusting operations of a height sensor by installing suspension arms to a suspension cross member which is formed in a separate body from a vehicle body and installed on the vehicle body and making the linking portion of the height sensor to springing weight the suspension cross member. CONSTITUTION:First, suspension arms 11-14 are linked to a cross member 1 in a condition that no cross member 1 is installed on a vehicle body, while linking the arms 11-14 to a wheel supporting portion 15. Then, the body 21 of a height sensor is linked to a front side lower arm 12 by means of the links 23 and 24 of the height sensor 21. The installation of the body 21 to the cross member 1 may be carried out at an appropriate time, e.g., either before or after linking the arm 11-14 to the cross member 1 so long as it is prior to the linking operation of the links 23, 24. The adjusting operation of the height sensor 21 is carried out after the linking operation of the links 23, 24 and, finally, the cross member 1 is installed on the vehicle body.

Description

【発明の詳細な説明】 （産業上の利用分野） 本発明は車高センサを備えた車両のサスペンション装置
およびその組立方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a suspension device for a vehicle equipped with a vehicle height sensor and a method for assembling the same.

（従来技術） 最近の車両では車高調整等を行なうものが増加する傾向
にあり、このために、車高を検出するための車高センサ
が必要となる。(Prior Art) There has been a trend in recent vehicles to have vehicle height adjustments, etc., and for this reason, a vehicle height sensor for detecting the vehicle height is required.

この車高センサは、結局のところ、ばね下重量に対する
ばね下重量の上下方向位置を知るものであり、このため
１例えば、ポテンショメータ等の本体をばね下重量に固
定する一方、リンク機構を介して当該ポテンショメータ
すなわちばね上重量とばね下重量とを連結するようにな
っている。This vehicle height sensor ultimately knows the vertical position of the unsprung weight relative to the unsprung weight, and for this reason, 1. For example, while fixing the main body such as a potentiometer to the unsprung weight, The potentiometer, that is, the sprung weight and the unsprung weight are connected.

そして、従来は、車高センサのばね下重量に対する連結
部としては、実開昭５９−１１１７１１号公報に示すよ
うに、車体フロアの下面というようようにされて、直接
的に車体に連結されるようになっていた。Conventionally, the connection part for the unsprung weight of the vehicle height sensor was connected directly to the car body, such as on the lower surface of the car body floor, as shown in Japanese Utility Model Application Publication No. 59-111711. It was like that.

（発明が解決しようとする問題点） しかしながら、上記従来のように、車高センサのばね下

う問題を生じる。(Problem to be Solved by the Invention) However, if the connection part for the unsprung weight of the vehicle height sensor is directly connected to the vehicle body as in the above-mentioned conventional method, the assembly work and assembly of the vehicle height sensor may be done later. This causes the problem that the work becomes troublesome.

この点を詳述すると、車高センサはばね下重量とばね下

ことになっていた。そして１組付は後の調整作業（微調
整）も、同様に車体下方にもぐりこんだ状態で行なうこ
とが強いられる。To explain this point in detail, the vehicle height sensor must be connected to both the unsprung weight and the unsprung weight, so for this connection work, the suspension arms etc. must be assembled to the vehicle body later. The worker was forced to crawl under the vehicle body in an awkward position to connect the vehicle height sensor to the underside of the vehicle floor and to the suspension arm, etc. After the first assembly, subsequent adjustment work (fine adjustment) must also be done while crawling under the vehicle body.

を受けることになる。In addition to this, when trying to accurately detect the vehicle height,
It is necessary to ensure that the connecting part of the vehicle height sensor to the vehicle body does not deform easily, but considering the fact that the floor surface of the vehicle body is quite easily deformed, this requirement is more than satisfied. It becomes difficult to do so. Of course, it is possible to select a portion of the vehicle body with excellent rigidity as the connecting portion, but in this case, the connecting portion of the vehicle height sensor is restricted.
