(EN) ELECTRIC PARKING BRAKE
(FR) FREIN DE STATIONNEMENT ÉLECTRIQUE
(JA) 電動パーキングブレーキ
Abstract
(EN) In order to prevent an accident by enabling the monitoring of an operation failure of an electric parking brake, in an electric parking brake in which an electric motor (10) and a direct-acting mechanism (11) are connected via a deceleration mechanism (12), and a lock pin (50) is engaged with the deceleration mechanism (12) by a solenoid (13), a monitoring means for detecting a change in the reactance (L) of the solenoid (13) is provided. The detected change in the reactance (L) is caused by the displacement of a plunger (53), and therefore an accident is prevented from occurring by monitoring a sliding failure of the lock pin (50) from the displacement.
(FR) L'invention concerne un frein de stationnement électrique. Afin d'empêcher un accident en activant la surveillance d'une défaillance de fonctionnement d'un frein de stationnement électrique, dans un frein de stationnement électrique dans lequel un moteur électrique (10) et un mécanisme à action directe (11) sont connectés par le biais d'un mécanisme de décélération (12), et dans lequel une goupille de verrouillage (50) est mise en prise avec le mécanisme de décélération (12) par un solénoïde (13), un moyen de surveillance est mis en œuvre pour détecter un changement au niveau de la réactance (L) du solénoïde (13). Le changement détecté au niveau de la réactance (L) est détecté par le déplacement d'un plongeur (53), et par conséquent un accident est évité par la surveillance d'une défaillance de coulissement de la goupille de verrouillage (50) suite au déplacement.
(JA)  電動パーキングブレーキの動作不良の監視ができるようにして事故を防止する。電動モータ(10)と直動機構(11)が減速機構(12)を介して接続され、前記減速機構(12)にロックピン(50)をソレノイド(13)により係合させる電動パーキングブレーキに、前記ソレノイド(13)のリアクタンス(L)の変化を検出する監視手段を設ける。検出したリアクタンス(L)の変化は、プランジャー(53)の変位によるものなので、その変位からロックピン(50)の摺動不良を監視することで事故の発生を未然に防止する。
