(JA) ストラットマウント
Abstract
(EN)
This strut mount (1) is provided with an inner member (21), an outer member (22), and a body rubber (23). A stopper rubber (30) that projects outward in the axial direction is provided to the body rubber. The outer member is provided with a supporting part (22a) that covers the stopper rubber from the outer side in the axial direction. The stopper rubber is provided with: a pedestal projection part (31) that projects outward in the axial direction from the inner member; and a tip projection part (32) that projects outward in the axial direction from the pedestal projection part, abuts against the supporting part, and has more flexible spring in the axial direction than the pedestal projection part. The pedestal projection part and the tip projection part project outward in the axial direction. The pedestal projection part has: an inner side surface (35) that is located at an inner end portion of the pedestal projection part in the radial direction and that extends outward in the axial direction from the inner member side; and an outer side surface (36) that gradually extends inward in the axial direction, from the outer end portion of the inner side surface in the axial direction toward the outer side in the radial direction. The tilt angle (θ1) of the outer side surface with respect to the horizontal line (L1) orthogonal to the center axis line (O) is less than the tilt angle (θ2) of the inner side surface. The tip projection part is provided to the outer side surface.

La présente invention concerne ce support de jambe de force (1) pourvu d'un élément interne (21), d'un élément externe (22) et d'un caoutchouc de corps (23). Un caoutchouc de butée (30) qui fait saillie vers l'extérieur dans la direction axiale est disposé sur le caoutchouc de corps. L'élément externe est pourvu d'une partie support (22a) qui recouvre le caoutchouc de butée à partir du côté externe dans la direction axiale. Le caoutchouc de butée est pourvu : d'une partie saillie du socle (31) qui fait saillie vers l'extérieur dans la direction axiale à partir de l'élément interne ; et d'une partie saillie de la pointe (32) qui fait saillie vers l'extérieur dans la direction axiale à partir de la partie saillie du socle, vient en butée contre la partie support et possède davantage de ressort flexible dans la direction axiale que la partie saillie du socle. La partie saillie du socle et la partie saillie de la pointe font saillie vers l'extérieur dans la direction axiale. La partie saillie du socle possède : une surface latérale interne (35) qui se trouve au niveau d'une partie extrémité interne de la partie saillie du socle dans la direction radiale et qui s'étend vers l'extérieur dans la direction axiale à partir du côté de l'élément interne ; et une surface latérale externe (36) qui s'étend progressivement vers l'intérieur dans la direction axiale, à partir de la partie extrémité externe de la surface latérale interne dans la direction axiale vers le côté externe dans la direction radiale. L'angle d'inclinaison (θ1) de la surface latérale externe par rapport à la ligne horizontale (L1) orthogonale à la ligne d'axe centrale (O) est inférieur à l'angle d'inclinaison (θ2) de la surface latérale interne. La partie saillie de la pointe est disposée sur la surface latérale externe.

このストラットマウント(1)は、内側部材(21)と、外側部材(22)と、本体ゴム(23)と、を備える。前記本体ゴムに、軸方向の外側に向けて突出したストッパゴム(30)が配設されている。前記外側部材は、前記ストッパゴムを前記軸方向の外側から覆う支持部(22a)を備える。前記ストッパゴムは、前記内側部材から前記軸方向の外側に向けて突出した台座突部(31)と、前記台座突部から前記軸方向の外側に向けて突出するとともに、前記支持部に当接し、前記台座突部より前記軸方向のばねが軟らかい先端突部(32)と、を備える。前記台座突部、および前記先端突部は、前記軸方向の外側に向けて尖っている。前記台座突部は、前記台座突部における径方向の内端部に位置し、前記内側部材側から前記軸方向の外側に向けて延びる内側面(35)と、前記内側面における前記軸方向の外端部から径方向の外側に向かうに従い漸次、前記軸方向の内側に向けて延びる外側面(36)と、を備える。前記外側面の、中心軸線(O)に直交する水平線(L1)に対する傾斜角度(θ1)は、前記内側面の前記傾斜角度(θ2)より小さい。前記先端突部は、前記外側面に配設されている。
