Abstract:
(EN) Provided are a small position detection sensor, a position detection system that uses said position detection sensor, and a belt-type continuously variable transmission provided with said position detection sensor, which enable the accurate detection of a position in the movement direction of a target (9), even if the target is displaced (juddered) in a direction perpendicular to the movement direction. The target (9) has a second member (4) that is less magnetic than a first member (3) and is positioned on the outer surface of the first member (3). At least one of the outer surface of the first member (3) and the outer surface of the second member (4) is sloped with respect to a prescribed direction, or formed in a stepped configuration along the prescribed direction. There are a plurality of coils (7, 8) positioned so as to face the outer surface of the second member (4) of the target (9) and driven at different frequencies. The position of the target (9) is detected using the change in impedance of the plurality of coils (7, 8) when a body to be detected moves.
(FR) L'invention concerne un capteur de détection de position de petite taille, un système de détection de position qui utilise ledit capteur de détection de position, et une transmission à variation continue du type à courroie comprenant ledit capteur de détection de position, qui permettent la détection précise d'une position dans la direction de déplacement d'une cible (9), même si la cible est déplacée (vibrée) dans une direction perpendiculaire à la direction de déplacement. La cible (9) a un second élément (4) qui est moins magnétique qu'un premier élément (3) et est positionné sur la surface externe du premier élément (3). Au moins l'une de la surface externe du premier élément (3) et de la surface externe du second élément (4) est inclinée par rapport à une direction prescrite, ou formée selon une configuration étagée le long de la direction prescrite. Une pluralité de bobines (7, 8) sont positionnées de manière à faire face à la surface externe du second élément (4) de la cible (9) et commandées à différentes fréquences. La position de la cible (9) est détectée à l'aide du changement d'impédance de la pluralité de bobines (7, 8) lorsqu'un corps à détecter se déplace.
(JA) ターゲット(9)が移動方向に垂直な方向で変位する(がたつく)場合でも、ターゲットの移動方向における位置を精度良く検出することのできる小型の位置検出センサ、該位置検出センサを用いた位置検出システム、及び該位置検出センサを備えたベルト式無段変速機を提供する。第1部材(3)の外面に該第1部材(3)より磁性の低い第2部材(4)が配置され、前記第1部材(3)の外面及び前記第2部材(4)の外面の少なくとも一方が前記所定方向に対して傾斜している若しくは前記所定方向に沿って階段状に形成されているターゲット(9)の前記第2部材(4)の外面に対面するように配置され、異なる周波数で駆動する複数のコイル(7,8)を有し、被検出体が移動するときの前記複数のコイル(7,8)のインピーダンス変化から、前記ターゲット(9)の位置を検出する。
