ここで、図７に示した止め具調整式の車高調整具１は、車高調整具本体１Ａに対する止め具２の高さ方向取付位置を調整可能にし、車高調整具本体１Ａに対するばね受具３の高さ方向取付位置を常時固定化するものとしている。 Here, the stopper adjustment type vehicle height adjuster 1 shown in FIG. The mounting position of the tool 3 in the height direction is always fixed.

即ち、図７に示した止め具調整式の車高調整具１にあっては、車高調整具本体１Ａにおける上端部寄りの外周につば状ばね受具３を常時固定的に備えるとともに、車高調整具本体１Ａの外周におけるばね受具３より下方の全長に渡ってねじ部を備える。車高調整具本体１Ａにおけるつば状ばね受具３より上方への突出部３Ｐにはばね６の下端内径部が挿着される。止め具２は、車高調整具本体１Ａのねじ部に螺着される筒状部２Ａを備えるとともに、筒状部２Ａの上端部につば部２Ｂを備える。止め具２の筒状部２Ａにおけるつば部２Ｂより下方への突出部２Ｐは、ロアアーム４に設けた取付孔４Ａに上方から挿着される。そして、車高調整具本体１Ａのねじ部に螺着された止め具２の筒状部２Ａにおける突出部２Ｐがロアアーム４の取付孔４Ａに挿入され、止め具２のつば部２Ｂの下面がロアアーム４の取付孔４Ａまわりの上面に載置された状態で、上記止め具２の下方から車高調整具本体１Ａのねじ部に螺着されたロックナット２Ｒの上端面が止め具２における筒状部２Ａの下端面に高さ方向で圧接される。これにより、車高調整具本体１Ａがロアアーム４に取付けられ、同時に止め具２が車高調整具本体１Ａにおけるねじ部の任意の高さ位置に螺着された一定の高さ方向取付位置に固定化され得るものになる。 That is, in the stopper adjustment type vehicle height adjuster 1 shown in FIG. A threaded portion is provided over the entire length below the spring support 3 on the outer periphery of the height adjuster main body 1A. A lower inner diameter portion of a spring 6 is inserted into a projecting portion 3P of the vehicle height adjuster main body 1A which protrudes upward from the collar-shaped spring receiver 3. As shown in FIG. The stopper 2 has a tubular portion 2A screwed onto the screw portion of the vehicle height adjuster main body 1A, and has a flange portion 2B at the upper end portion of the tubular portion 2A. A projecting portion 2P extending downward from the collar portion 2B of the tubular portion 2A of the stopper 2 is inserted into a mounting hole 4A provided in the lower arm 4 from above. Then, the projecting portion 2P of the cylindrical portion 2A of the stopper 2 screwed onto the threaded portion of the vehicle height adjuster main body 1A is inserted into the mounting hole 4A of the lower arm 4, and the lower surface of the collar portion 2B of the stopper 2 is attached to the lower arm. A lock nut 2R is screwed onto the threaded portion of the vehicle height adjuster body 1A from below the stopper 2 while being placed on the upper surface around the mounting hole 4A of the stopper 2. It is pressed against the lower end surface of the portion 2A in the height direction. As a result, the vehicle height adjuster main body 1A is attached to the lower arm 4, and at the same time, the stopper 2 is screwed to an arbitrary height position of the threaded portion of the vehicle height adjuster main body 1A and fixed at a fixed height direction mounting position. become something that can be transformed.

図７に示した止め具調整式の車高調整具１では、車高調整具本体１Ａにおける上端部寄りに常時固定化されているばね受具３のロアアーム４に対する高さ方向取付位置を図７（Ａ）の最低位置に設定することで、車高を低くした最小車高状態を得る。他方、上記ばね受具３のロアアーム４に対する高さ方向取付位置を図７（Ｂ）の最高位置に設定することで、車高を高くした最大車高状態を得る。 In the height adjuster 1 of the stopper adjustment type shown in FIG. 7, the mounting position in the height direction with respect to the lower arm 4 of the spring receiver 3, which is always fixed near the upper end portion of the height adjuster main body 1A, is shown in FIG. By setting to the lowest position of (A), a minimum vehicle height state is obtained in which the vehicle height is lowered. On the other hand, by setting the mounting position of the spring bearing 3 to the lower arm 4 in the height direction to the highest position in FIG. 7B, the maximum vehicle height is obtained.

従って、図７に示した止め具調整式の車高調整具１では、図７に示したＨ1が車高調整範囲となり、車高調整具本体１Ａに形成されるねじ部を長く設定することで、車高調整範囲Ｈ1を大きくとることができる（Ｈ1＞図８の例において、車高調整具本体１Ａの全高を図７の例におけると同一高さに設定したときの車高調整範囲Ｈ2）。 Therefore, in the fastener adjustment type vehicle height adjuster 1 shown in FIG. 7, H1 shown in FIG. , the vehicle height adjustment range H1 can be widened (H1> vehicle height adjustment range H2 when the overall height of the vehicle height adjuster main body 1A is set to the same height as in the example of FIG. 7 in the example of FIG. 8). .

また、図７に示した止め具調整式の車高調整具１では、最小車高状態で車体５のバンプ時にばね６が密着しても、車高調整具本体１Ａがロアアーム４より上方に大きく突出していないから、図７（Ｃ）に示す如く、車体５の凸部５Ａが車高調整具本体１Ａの上端面に干渉するおそれがない。 In addition, in the height adjuster 1 of the stopper adjustment type shown in FIG. 7, even if the spring 6 is in close contact when the vehicle body 5 bumps in the minimum vehicle height state, the vehicle height adjuster main body 1A will be greatly above the lower arm 4. Since it does not protrude, as shown in FIG. 7(C), there is no possibility that the convex portion 5A of the vehicle body 5 will interfere with the upper end surface of the vehicle height adjuster main body 1A.

但し、図７に示した止め具調整式の車高調整具１では、最小車高状態に設定されたときの車高調整具本体１Ａがロアアーム４より下方に大きく突出する（突出長さＬ1）。下方に突出した車高調整具本体１Ａと路面とのクリアランスが狭くなり、車高調整具本体１Ａが路面側の障害物に接触する可能性が大きくなる。また、車高調整具本体１Ａが下方に大きく突出していて、車両の美観も損なう。 However, in the fastener-adjustable vehicle height adjuster 1 shown in FIG. 7, the vehicle height adjuster main body 1A protrudes greatly downward from the lower arm 4 when set to the minimum vehicle height state (projection length L1). . The clearance between the vehicle height adjuster main body 1A projecting downward and the road surface becomes narrower, and the possibility of the vehicle height adjuster main body 1A coming into contact with obstacles on the road surface side increases. In addition, the vehicle height adjuster main body 1A protrudes greatly downward, which impairs the appearance of the vehicle.

他方、図８に示したばね受具調整式の車高調整具１は、車高調整具本体１Ａに対するばね受具３の高さ方向取付位置を調整可能にし、車高調整具本体１Ａに対する止め具２の高さ方向取付位置を常時固定化している。 On the other hand, the spring bearing adjustment type vehicle height adjuster 1 shown in FIG. 2 is always fixed in the height direction mounting position.

即ち、図８に示したばね受具調整式の車高調整具１にあっては、車高調整具本体１Ａにおける下端部寄りの外周につば状止め具２を常時固定的に備えるとともに、車高調整具本体１Ａの外周における止め具２より上方の全長に渡ってねじ部を備える。車高調整具本体１Ａにおけるつば状止め具２より下方への突出部２Ｐはロアアーム４に設けた取付孔４Ａに上方から挿着される。そして、ばね受具３は、車高調整具本体１Ａのねじ部に螺着される筒状部３Ａを備えるとともに、筒状部３Ａの下端部につば部３Ｂを備える。ばね受具３の筒状部３Ａにおけるつば部３Ｂより上方への突出部３Ｐにはばね６の下端内径部が挿着される。これにより、止め具２の突出部２Ｐがロアアーム４の取付孔４Ａに挿着された状態で、車高調整具本体１Ａがロアアーム４に取付けられるものになる。また、車高調整具本体１Ａのねじ部にばね受具３の筒状部３Ａが螺着され、該ばね受具３の上方又は下方から該車高調整具本体１Ａのねじ部に螺着されたロックナット３Ｒ（図８（Ａ）又は（Ｂ））の下端面又は上端面が上記ばね受具３の筒状部３Ａの上端面に又は下端面に高さ方向で圧接されることにて、ばね受具３が車高調整具本体１Ａにおけるねじ部の任意の高さ位置に螺着された一定の高さ方向取付位置に固定化され得るものになる。 That is, in the vehicle height adjuster 1 of the spring bearing adjustment type shown in FIG. A screw portion is provided over the entire length above the stopper 2 on the outer periphery of the adjuster main body 1A. A projecting portion 2P of the vehicle height adjuster main body 1A extending downward from the flange-like stopper 2 is inserted into a mounting hole 4A provided in the lower arm 4 from above. The spring receiver 3 includes a tubular portion 3A screwed onto the threaded portion of the vehicle height adjuster main body 1A, and a flange portion 3B at the lower end of the tubular portion 3A. The inner diameter portion of the lower end of the spring 6 is inserted into the projecting portion 3P of the cylindrical portion 3A of the spring receiver 3 which protrudes upward from the flange portion 3B. As a result, the vehicle height adjuster main body 1A is attached to the lower arm 4 while the projection 2P of the stopper 2 is inserted into the attachment hole 4A of the lower arm 4. As shown in FIG. The cylindrical portion 3A of the spring receiver 3 is screwed onto the threaded portion of the vehicle height adjuster main body 1A, and the spring receiver 3 is screwed from above or below to the threaded portion of the vehicle height adjuster main body 1A. The lower or upper end surface of the lock nut 3R (FIG. 8(A) or (B)) is pressed against the upper or lower end surface of the cylindrical portion 3A of the spring receiver 3 in the height direction. , the spring receiver 3 can be fixed at a fixed height mounting position screwed to an arbitrary height position of the threaded portion of the vehicle height adjuster main body 1A.

図８に示したばね受具調整式の車高調整具１では、ばね受具３を、車高調整具本体１Ａに対する高さ方向の下端側取付位置に固定化し、結果として、ロアアーム４に対するばね受具３の高さ方向設定位置を図８（Ａ）の最低位置に設定することで、車高を低くした最小車高状態を得る。他方、ばね受具３を車高調整具本体１Ａに対する高さ方向の上端側取付位置に固定化し、結果として、ロアアーム４に対するばね受具３の高さ方向設定位置を図８（Ｂ）の最高位置に設定することで、車高を高くした最大車高状態を得る。 In the spring-receiving-adjustable vehicle height adjuster 1 shown in FIG. By setting the setting position of the tool 3 in the height direction to the lowest position in FIG. 8A, a minimum vehicle height state is obtained. On the other hand, the spring bearing 3 is fixed at the upper mounting position in the height direction with respect to the vehicle height adjuster main body 1A. By setting it to the position, the maximum vehicle height state with the vehicle height raised is obtained.

従って、図８に示したばね受具調整式の車高調整具１では、図８に示したＨ2が車高調整範囲となる。また、図８に示したばね受具調整式の車高調整具１では、最小車高状態における車体５のバンプ時にばね６が密着したとき、車高調整具本体１Ａがロアアーム４より上方に大きく突出するから、図８（Ｃ）に示す如く、車体５の凸部５Ａが車高調整具本体１Ａの上端面に干渉しないように該車高調整具本体１Ａの高さを制限する必要がある。即ち、図８に示したばね受具調整式の車高調整具１では、車高調整具本体１Ａを高いものにしてそのねじ部を長くすることに制限があり、車高調整範囲Ｈ2を大きくとることに困難がある。 Therefore, in the vehicle height adjuster 1 of the spring bearing adjustment type shown in FIG. 8, H2 shown in FIG. 8 is the vehicle height adjustment range. 8, the vehicle height adjuster body 1A protrudes significantly above the lower arm 4 when the spring 6 is in close contact with the vehicle body 5 when the vehicle body 5 bumps in the minimum vehicle height state. Therefore, as shown in FIG. 8C, it is necessary to limit the height of the vehicle height adjuster main body 1A so that the convex portion 5A of the vehicle body 5 does not interfere with the upper end surface of the vehicle height adjuster main body 1A. That is, in the vehicle height adjuster 1 of the spring bearing adjustment type shown in FIG. 8, there is a limit to increasing the height of the vehicle height adjuster main body 1A and lengthening the threaded portion, so that the vehicle height adjustment range H2 is large. There are difficulties in

請求項２に係る発明は、請求項１に係る発明において更に、前記止め具が、車高調整具本体に螺着されるとともに、該車高調整具本体に螺着されたロックナットに高さ方向で圧接され、車高調整具本体に対する一定の高さ方向取付位置に固定化されるようにしたものである。 The invention according to claim 2 is characterized in that, in the invention according to claim 1, the stopper is screwed to the vehicle height adjuster main body, and further has a lock nut screwed to the vehicle height adjuster main body. It is fixed in a fixed height direction mounting position with respect to the vehicle height adjuster main body.

請求項３に係る発明は、請求項１又は２に係る発明において更に、前記ばね受具が、車高調整具本体に螺着されるとともに、該車高調整具本体に螺着されたロックナットに高さ方向で圧接され、車高調整具本体に対する一定の高さ方向取付位置に固定化されるようにしたものである。 The invention according to claim 3 is, in the invention according to claim 1 or 2, further comprising a lock nut screwed to the vehicle height adjuster body while the spring receiving device is screwed to the vehicle height adjuster body. , and is fixed at a fixed height mounting position with respect to the vehicle height adjuster main body.

請求項４に係る発明は、請求項３に係る発明において更に、前記止め具とそのロックナット、及び前記ばね受具とそのロックナットが螺着されるねじ部が、車高調整具本体の外周における軸方向の全長に渡って形成されるようにしたものである。 The invention according to claim 4 is the invention according to claim 3, further comprising: a threaded portion to which the stopper and its lock nut, and the spring bearing and its lock nut are screwed; It is formed over the entire length in the axial direction.

(a)止め具とばね受具の双方が車高調整具本体に対する高さ方向取付位置を調整可能にされている。従って、ばねが密着する車体のバンプ時に、車高調整具本体の上端面が車体の凸部に干渉するおそれがある最小車高状態で、止め具とばね受具のそれぞれが車高調整具本体に対してなす高さ方向取付位置を車高調整具本体の高さ方向の中間の好適位置に設定することで、車高調整具本体の上端面が車体の凸部に干渉しない位置まで該車高調整具本体をロアアームの上方へ最大限突出させることができ、結果として最小車高状態における車高調整具本体のロアアームより下方への突出長さを最小限に納めることができる。 (a) Both the stopper and the spring retainer are adjustable in the height direction mounting position with respect to the vehicle height adjuster body. Therefore, when the vehicle body bumps against which the spring is in close contact, the stopper and the spring receiver are in the minimum vehicle height state where the upper end surface of the vehicle height adjuster body may interfere with the convex portion of the vehicle body. By setting the mounting position in the height direction to a suitable position in the middle of the vehicle height adjuster body in the height direction, the upper end surface of the vehicle height adjuster body does not interfere with the convex portion of the vehicle body. The height adjuster main body can be projected above the lower arm to the maximum extent, and as a result, the length of protrusion of the height adjuster main body downward from the lower arm in the minimum vehicle height state can be minimized.

下方に突出した車高調整具本体と路面とのクリアランスが広くなり、車高調整具本体が路面側の障害物に接触する可能性が小さくなる。また、車高調整具本体が下方に大きく突出することがなく、車両の美観を損なうこともない。 The clearance between the vehicle height adjuster body projecting downward and the road surface is widened, and the possibility of the vehicle height adjuster body coming into contact with an obstacle on the road surface side is reduced. In addition, the body of the vehicle height adjuster does not protrude greatly downward, and the aesthetic appearance of the vehicle is not spoiled.

(b)最小車高状態では、車高調整具本体における上述(a)の中間位置に取付けた止め具をロアアームに取付け、この止め具の上部に設定されるばね受具によりばねを支承することにて、車高を低くできる。 (b) In the minimum vehicle height state, the stopper installed at the intermediate position of (a) above on the vehicle height adjuster body is attached to the lower arm, and the spring is supported by the spring receiver set on the upper part of this stopper. , the vehicle height can be lowered.

最大車高状態では、車高調整具本体における高さ方向の下端側取付位置に取付けた止め具をロアアームに取付けるとともに、車高調整具本体における高さ方向の上端側取付位置に取付けたばね受具によりばねを支承することにて、車高を高くできる。 In the maximum vehicle height state, the stopper attached to the lower mounting position in the height direction of the vehicle height adjuster body is attached to the lower arm, and the spring retainer is attached to the upper mounting position in the height direction of the vehicle height adjuster body. The vehicle height can be increased by supporting the spring.

従って、車高調整具本体の全高を高くし、該車高調整具本体に形成されるねじ部を長く設定することで、車高調整範囲Ｈ0を大きくとることができる（Ｈ0＝図７の例において、車高調整具本体の全高を図６の例におけると同一高さに設定したときの車高調整範囲Ｈ1）。 Therefore, by increasing the overall height of the vehicle height adjuster body and setting a long screw portion formed in the vehicle height adjuster body, the vehicle height adjustment range H0 can be increased (H0 = example in FIG. 7). 3, the vehicle height adjustment range H1) when the overall height of the vehicle height adjuster body is set to the same height as in the example of FIG.

車高調整具本体２１の高さ方向で止め具３０、ばね受具４０を螺動し、ねじ部２２の最下位置に止め具３０を螺着させ、ねじ部２２の最上位置にばね受具４０を螺着させ、止め具３０に対するつば部３２の下端面（ロアアーム１３への取付け面）とばね受具４０におけるつば部４２の上端面（ばね１４の支承面）とがなす間隔を最大化すように（止め具３０におけるつば部３２の上端面にロックナット３３が圧接し、ばね受具４０におけるつば部４２の下端面にロックナット４３が圧接する）、止め具３０とばね受具４０の車高調整具本体２１に対する高さ方向取付位置を調整する。この結果、ロアアーム１３に対する止め具３０とばね受具４０の高さ方向設定位置が調整され、車高調整具２０を用いた最大車高状態を得る。 (2) Maximum vehicle height (Fig. 6 (B))
The stopper 30 and the spring receiver 40 are screwed in the height direction of the vehicle height adjuster main body 21 , the stopper 30 is screwed to the lowest position of the threaded portion 22 , and the spring receiver is attached to the highest position of the threaded portion 22 . 40 is screwed to maximize the distance between the lower end surface of the flange portion 32 (attachment surface to the lower arm 13) with respect to the stopper 30 and the upper end surface (bearing surface of the spring 14) of the spring receiver 40. (the lock nut 33 is pressed against the upper end surface of the flange portion 32 of the stopper 30, and the lock nut 43 is pressed against the lower end surface of the flange portion 42 of the spring receiver 40). The mounting position in the height direction with respect to the vehicle height adjuster main body 21 is adjusted. As a result, the height setting positions of the stopper 30 and the spring support 40 with respect to the lower arm 13 are adjusted, and the maximum vehicle height using the vehicle height adjuster 20 is obtained.

(3)中間車高状態
図６（Ａ）に示した最小車高状態における止め具３０とばね受具４０の間隔を適宜拡大し、又は図６（Ｂ）に示した最大車高状態における止め具３０とばね受具４０の間隔を適宜減縮するように、止め具３０とばね受具４０の車高調整具本体２１に対する高さ方向取付位置を調整する。この結果、ロアアーム１３に対する止め具３０とばね受具４０の高さ方向設定位置が調整され、車高調整具２０を用いた最小車高状態と最大車高状態の中間の中間車高状態を得る。 (3) Intermediate vehicle height state The distance between the stopper 30 and the spring bearing 40 in the minimum vehicle height state shown in FIG. The mounting positions of the stopper 30 and the spring receiver 40 in the height direction with respect to the vehicle height adjuster main body 21 are adjusted so as to appropriately reduce the distance between the tool 30 and the spring receiver 40 . As a result, the height direction setting positions of the stopper 30 and the spring support 40 with respect to the lower arm 13 are adjusted, and an intermediate vehicle height state intermediate between the minimum vehicle height state and the maximum vehicle height state using the vehicle height adjuster 20 is obtained. .
