Title (EN) VEHICLE HEIGHT ADJUSTING DEVICE
(FR) DISPOSITIF D'AJUSTEMENT DE HAUTEUR DE VÉHICULE

Abstract:
(EN) A displaceable spring seat (2) for supporting one end of a suspension spring (S) of a vehicle is supported by fluid pressure in an operating chamber (J).  A screw pump (P) for supplying an operating fluid to the operating chamber (J) is provided with a pump chamber (L) which is defined within a cylinder (10) by a piston (11).  A nut (13) is integrated with the piston (11), and a screw shaft (14) is engaged with the nut (13) through threads.  When the screw shaft (14) is driven rotationally, a guide member (16) which is affixed to the cylinder (10) is engaged with the outer periphery of the nut (13) or of the piston (11) so as to screw-feed the piston (11) through the nut (13).  The guide member (16) consisting of a non-metallic low-friction material reduces resistance in the driving of the piston (11), and this enhances the durability of the thread-engaged section between the nut (13) and the screw shaft (14).
(FR) Selon l'invention, un siège de ressort déplaçable (2) destiné à supporter une extrémité d'un ressort de suspension (S) d'un véhicule est supporté par une pression de fluide dans une chambre de travail (J). Une pompe à vis (P) destinée à alimenter en fluide de travail la chambre de travail (J) comprend une chambre de pompe (L) qui est définie à l'intérieur d'un cylindre (10) par un piston (11). Un écrou (13) est intégré au piston (11), et un arbre à vis (14) est en prise avec l'écrou (13) par le biais de filetages. Lorsque l'arbre à vis (14) est entraîné en rotation, un élément de guidage (16) qui est fixé au cylindre (10) est amené à venir en prise avec la périphérie externe de l'écrou (13) ou du piston (11) de façon à faire avancer le piston (11) à travers l'écrou (13). L'élément de guidage (16) consistant en un matériau à faible frottement et non métallique réduit la résistance à l'entraînement du piston (11), et ceci améliore la durabilité de la section de prise par filetage entre l'écrou (13) et l'arbre à vis (14).
(JA) 車両の懸架バネ (S) の一端を支持する変位可能なスプリングシート (2) を作動室 (J) の流体圧で支持する。作動室 (J) に作動流体を供給するねじポンプ (P) はシリンダ (10) の内側にピストン (11) に画成されたポンプ室 (L) を備える。ピストン (11) にはナット (13) が一体化され、ナット (13) にねじ軸 (14) が螺合する。ねじ軸 (14) の回転駆動により、ナット (13) を介してピストン (11) をねじ送りすべく、シリンダ (10) に固定されたガイド部材 (16) がナット (13) またはピストン (11) の外周に嵌合する。非金属製の低摩擦材料で構成されたガイド部材 (16) がピストン (11) の駆動抵抗を減らし、ナット (13) とねじ軸 (14) との螺合部の耐久性を高める。
