By providing this wall portion, it is possible to shield brake dust and splash from below from causing the corrosion. Thereby, in this invention, corrosion resistance can be improved. Further, according to the present invention, it is possible to increase the wall thickness on the knuckle side, and the NV resistance can be improved by reducing the natural vibration frequency.

さらに、本発明は、前記ナックルが、前記壁部と略直交して前記二股部の下部を繋ぐ他の壁部を有することを特徴とする。   Furthermore, the present invention is characterized in that the knuckle has another wall portion that is substantially orthogonal to the wall portion and connects the lower portion of the bifurcated portion.

本発明によれば、壁部と略直交する他の壁部を設けることで、二股部の下側からのスプラッシュを他の壁部で確実に遮蔽することができる。   According to the present invention, by providing another wall portion substantially orthogonal to the wall portion, the splash from the lower side of the bifurcated portion can be reliably shielded by the other wall portion.

The control arm connecting portion 40b is provided on the left side of the frame body 36 when viewed from the inside in the vehicle width direction (see FIG. 3A), and a control arm (not shown) is connected. The pair of brake caliper connecting portions 40c and 40d are provided at predetermined distances apart from each other on the right side of the frame body 36 and the bifurcated portion 30 when viewed from the inside in the vehicle width direction (see FIG. 3A). A caliper is attached.

二股部３０は、互いに対向し本体部２８から上方に向かって略平行に延在する一対の分岐壁４２、４２を有する。また、二股部３０は、略上下方向に沿って延在し、一対の分岐壁４２、４２の側部同士を繋ぐ側壁部（壁部）４４を有する。側壁部４４は、左前輪２０と近接する部位に設けられている（図１参照）。   The bifurcated portion 30 has a pair of branch walls 42 and 42 that face each other and extend substantially in parallel upward from the main body portion 28. The bifurcated portion 30 has a side wall portion (wall portion) 44 that extends substantially in the vertical direction and connects the side portions of the pair of branch walls 42 and 42. The side wall portion 44 is provided at a site close to the left front wheel 20 (see FIG. 1).

さらに、二股部３０は、略上下方向と直交する方向に延在し一対の分岐壁４２、４２の下端同士を繋ぐ下壁部（他の壁部）４６を有する。下壁部４６は、側壁部４４の下端から車幅方向内側に向かって突出するように設けられている。二股部３０には、一対の分岐壁４２、４２、側壁部４４、及び、下壁部４６によって囲繞された空間部４８（図２（ｂ）参照）が形成される。空間部４８は、二股部３０の車幅方向内側の開口５０及び上部側の開口５２と連通している（図２（ｂ）、図３（ｄ）参照）。   Further, the bifurcated portion 30 has a lower wall portion (other wall portion) 46 that extends in a direction substantially orthogonal to the vertical direction and connects the lower ends of the pair of branch walls 42 and 42. The lower wall portion 46 is provided so as to protrude inward in the vehicle width direction from the lower end of the side wall portion 44. The bifurcated portion 30 is formed with a space portion 48 (see FIG. 2B) surrounded by a pair of branch walls 42, 42, a side wall portion 44, and a lower wall portion 46. The space portion 48 communicates with the opening 50 on the inner side in the vehicle width direction and the opening 52 on the upper side of the bifurcated portion 30 (see FIGS. 2B and 3D).

各分岐壁４２には、ボルト５４（図１参照）が挿通されるボルト挿通孔５６が形成されている（図３（ｂ）参照）。一対の分岐壁４２、４２のボルト挿通孔５６及び突条部２６（連結部材２２）のボルト挿通孔（図示せず）に沿ってボルト５４を挿通し、ボルト５４のねじ部に図示しないナットを締結することで、連結部材２２が二股部３０によって挟持固定される。   Each branch wall 42 is formed with a bolt insertion hole 56 through which a bolt 54 (see FIG. 1) is inserted (see FIG. 3B). A bolt 54 is inserted along a bolt insertion hole 56 of the pair of branch walls 42 and 42 and a bolt insertion hole (not shown) of the ridge 26 (connecting member 22), and a nut (not shown) is attached to a screw portion of the bolt 54. By fastening, the connecting member 22 is clamped and fixed by the bifurcated portion 30.

ボルト５４及びナットによって連結部材２２が二股部３０に挟持固定された際、突条部２６の下端面と下壁部４６の上面との間には、クリアランスが形成されている。ストラット型サスペンション１０が車両に実装された際、上部側の開口部５２を介して空間部４８内に進入した水等は、このクリアランスを介して外部に排出される。また、空間部４８に臨む下壁部４６の上面は、例えば、側壁部４４から離間する方向に向かって下方に立ち下がる傾斜面で形成されることで、排出性を向上させることができる。   When the connecting member 22 is clamped and fixed to the bifurcated portion 30 by the bolt 54 and the nut, a clearance is formed between the lower end surface of the protruding portion 26 and the upper surface of the lower wall portion 46. When the strut suspension 10 is mounted on the vehicle, water and the like that has entered the space 48 through the opening 52 on the upper side is discharged to the outside through this clearance. Further, the upper surface of the lower wall portion 46 facing the space portion 48 is formed with, for example, an inclined surface that falls downward in a direction away from the side wall portion 44, so that the discharge performance can be improved.

なお、突条部２６の下端面と下壁部４６の上面との間にクリアランスを設けることなく、図示しない排水手段を設けることで、突条部２６の下端面と下壁部４６の上面とを当接させるようにしてもよい。突条部２６及び下壁部４６を互いに当接させることで、組み付け時における一対の分岐壁４２、４２のボルト挿通孔５６と、突条部２６のボルト挿通孔（図示せず）との位置決めに利用することができる。   In addition, by providing a drainage means (not shown) without providing a clearance between the lower end surface of the ridge portion 26 and the upper surface of the lower wall portion 46, the lower end surface of the ridge portion 26 and the upper surface of the lower wall portion 46 are provided. You may make it contact | abut. Positioning between the bolt insertion holes 56 of the pair of branch walls 42 and 42 and the bolt insertion holes (not shown) of the protrusion 26 by assembling the protrusion 26 and the lower wall 46 with each other. Can be used.

側壁部４４は、車幅方向内側から見て縦長矩形状の壁部からなり（図３（ａ）参照）、連結部材２２の突条部２６よりも車輪（左前輪２０）に近接した車幅方向外側に位置している（図１参照）。また、側壁部４４は、車幅方向内側から見て連結部材２２（有底円筒部２４、突条部２６）と重畳する位置に配置されている（後記する図４参照）。   The side wall portion 44 is a vertically long rectangular wall portion as viewed from the inside in the vehicle width direction (see FIG. 3A), and is closer to the wheel (the left front wheel 20) than the protruding portion 26 of the connecting member 22. It is located outside in the direction (see FIG. 1). Moreover, the side wall part 44 is arrange | positioned in the position which overlaps with the connection member 22 (bottomed cylindrical part 24, the protrusion part 26) seeing from the vehicle width direction inner side (refer FIG. 4 mentioned later).

下壁部４６は、上面視（平面視）して車幅方向に沿った略矩形状に形成されている。下壁部４６を設けることで、二股部３０の下部側の空間部４８が閉塞されている（図２（ｂ）参照）。   The lower wall portion 46 is formed in a substantially rectangular shape along the vehicle width direction when viewed from above (plan view). By providing the lower wall portion 46, the space portion 48 on the lower side of the bifurcated portion 30 is closed (see FIG. 2B).

Yes. Further, the side wall portion 44 of the knuckle 18 is provided so as to connect the side surfaces of the pair of branch walls 42 and 42 of the bifurcated portion 30.

本実施形態では、側壁部４４が防護壁として機能することで、例えば、図示しないブレーキ装置で発生し腐蝕原因となるブレーキダストや下方からのスプラッシュを、突条部２６から好適に遮蔽することができる。この結果、本実施形態では、ダンパ１２をナックル１８に取り付ける連結部材２２（突条部２６）の耐腐蝕性を向上させることができる。   In the present embodiment, the side wall portion 44 functions as a protective wall, so that, for example, brake dust generated in a brake device (not shown) and causing corrosion can be suitably shielded from the protrusion 26. it can. As a result, in this embodiment, it is possible to improve the corrosion resistance of the connecting member 22 (the protruding portion 26) that attaches the damper 12 to the knuckle 18.

また、本実施形態では、ナックル１８を構成する分岐壁４２や縦壁３２等の肉厚を従来と比較して増大させることができる。これにより、本実施形態では、固有振動周波数の低減により、耐ＮＶ性能を向上させることができる。   Moreover, in this embodiment, the thickness of the branch wall 42, the vertical wall 32, etc. which comprise the knuckle 18 can be increased compared with the past. Thereby, in this embodiment, NV performance can be improved by reducing the natural vibration frequency.
