Title
(EN) ELECTRONIC CONTROL THROTTLE BODY
(FR) CORPS DE PAPILLON A COMMANDE ELECTRONIQUE
Abstract
(EN)
An electronic control throttle body comprises a torque motor (20) having a stator and a mover (slider) (25) and a throttle shaft (4) rotated by the torque motor. A rack (25b) serving as teeth is provided to the mover. A gear (30) in engagement with the rack is provided to the throttle shaft (4). The radius of the gear (30) is determined appropriately with respect to the range where the slider (25) moves, and therefore the movement of the slider (25) can be transmitted to the throttle shaft (4) effectively. As a result, a simply-structured electronic control throttle body for efficiently transmitting the drive of a torque motor such as a linear motor to the throttle shaft is provided.
(FR)
Un corps de papillon à commande électronique comprend un moteur couple (20) présentant un stator et un organe de mouvement (coulisse) (25) et un axe (4) de papillon mis en rotation par le moteur couple. Une crémaillère (25b) servant de dents est destinée à l'organe de mouvement. Un engrenage (30) en prise avec la crémaillère est prévu pour l'axe (4) du papillon. Le rayon de l'engrenage (30) est déterminé de façon appropriée par rapport à la distance que parcourt la coulisse (25), et par conséquent le mouvement de la coulisse (25) peut être transmis efficacement à l'axe (4) du papillon. Ainsi on peut obtenir un corps de papillon à commande électronique de structure simple permettant de transmettre efficacement l'entraînement d'un moteur couple tel qu'un moteur linéaire à l'axe du papillon.
