Title
(EN) VEHICLE STABILIZER SYSTEM
(FR) SYSTÈME STABILISATEUR DE VÉHICULE
Abstract
(EN)
A stabilizer system for a vehicle, including: (a) a stabilizer bar (28) including (a-1) a torsion bar portion (90), and (a-2) an arm portion (92) that extends from the torsion bar portion toward a wheel (12) of the vehicle; and (b) an actuator (32) including (b-1) a motor (40), and (b-2) a speed reducer (42) that reduces a speed of the motor while transmitting a force of the motor to the torsion bar portion of the stabilizer bar. The stabilizer bar generates a stabilizing force which is dependent on a reaction generated as a result of torsion of the torsion bar portion, and which forces the wheel and the vehicle body in a direction toward each other or a direction away from each other. The actuator allows the stabilizer bar to generate the stabilizing force whose magnitude is dependent on a magnitude of the motor force and is changeable depending on an amount of rotation of the torsion bar portion. The actuator includes an actuator-efficiency changing mechanism changing a negative efficiency of the actuator, depending on a direction of the force of the motor.
(FR)
L'invention concerne un système stabilisateur pour un véhicule, comprenant: (a) une barre stabilisatrice (28) comprenant (a-1) une partie barre de torsion (90) et (a-2) une partie bras (92) qui s'étend de la partie barre de torsion à une roue (12) du véhicule; et (b) un actionneur (32) comprenant (b-1) un moteur (40) et (b-2) un réducteur de vitesse (42) qui réduit une vitesse du moteur tout en transmettant une force du moteur à la partie barre de torsion de la barre stabilisatrice. La barre stabilisatrice génère une force de stabilisation qui dépend d'une réaction générée à la suite d'une torsion de la partie barre de torsion, et qui force la roue et le corps de véhicule dans un sens de rapprochement l'un vers l'autre ou dans un sens d'éloignement l'un de l'autre. L'actionneur permet à la barre stabilisatrice de générer la force de stabilisation dont l'amplitude dépend de l'amplitude de la force du moteur et peut être modifée en fonction d'une quantité de rotation de la partie barre de torsion. L'actionneur comprend un mécanisme de modification de rendement de l'actionneur modifiant un rendement négatif de l'actionneur, en fonction d'un sens de la force du moteur.
