Title (EN) STEERING FUNCTION-EQUIPPED HUB UNIT AND VEHICLE PROVIDED THEREWITH
(FR) UNITÉ DE MOYEU ÉQUIPÉE D'UNE FONCTION DE DIRECTION ET VÉHICULE ÉQUIPÉ DE CELLE-CI
(JA) 転舵機能付ハブユニットおよびそれを備えた車両
Abstract:
(EN) This auxiliary steering function-equipped hub unit (1) is provided with: a hub unit body (2); a unit supporting member (3) which supports the hub unit body (2) such that the hub unit body (2) is rotatable about an auxiliary steering axis; and an auxiliary steering actuator (5) for rotationally driving the hub unit body (2). The auxiliary steering actuator (5) has a motor (26) and a linear motion mechanism (25) which converts rotational output of the motor (26) into a linear motion. The linear motion mechanism (25) has: a feed screw mechanism (30) which is coupled to the hub unit body (2); a rotary support bearing (31) which rotationally supports the feed screw mechanism (30); and a preload application means (33) which applies, to the rotary support bearing (31), a preload that is equal to or greater than a reaction force inputted thereto from outside.
(FR) Unité de moyeu équipée d'une fonction de direction auxiliaire (1) pourvue : d'un corps (2) d'unité de moyeu ; d'un élément de support (3) d'unité qui supporte le corps (2) d'unité de moyeu de telle sorte que le corps (2) d'unité de moyeu peut tourner autour d'un axe de direction auxiliaire ; et d'un actionneur de direction auxiliaire (5) pour entraîner en rotation le corps (2) d'unité de moyeu. L'actionneur de direction auxiliaire (5) comporte un moteur (26) et un mécanisme de mouvement linéaire (25) qui convertit une sortie de rotation du moteur (26) en un mouvement linéaire. Le mécanisme de mouvement linéaire (25) comporte : un mécanisme de vis d'alimentation (30) qui est accouplé au corps (2) d'unité de moyeu ; un palier de support rotatif (31) qui supporte en rotation le mécanisme de vis d'alimentation (30) ; et un moyen d'application de précharge (33) qui applique, au palier de support rotatif (31), une précharge qui est égale ou supérieure à une force de réaction entrée dans celui-ci depuis l'extérieur.
(JA) この補助転舵機能付ハブユニット(1)は、ハブユニット本体(2)と、ハブユニット本体(2)を補助転舵軸心回りに回転自在に支持するユニット支持部材(3)と、ハブユニット本体(2)を回転駆動させる補助転舵用アクチュエータ(5)とを備える。補助転舵用アクチュエータ(5)は、モータ(26)と、モータ(26)の回転出力を直線動作に変換する直動機構(25)とを有する。直動機構(25)は、ハブユニット本体(2)に連結された送りねじ機構(30)と、送りねじ機構(30)を回転支持する回転支持軸受(31)と、回転支持軸受(31)に外部から入力される反力以上の予圧を与える予圧付与手段(33)とを有する。
