Title (EN) SERVO-ASSISTED GEAR SELECTOR
(FR) SELECTEUR DE VITESSES SERVOCOMMANDE
Abstract:
(EN) Servo-assisted gear selector for a motor vehicle gearbox (1) and a gear change controlled by the driver by operating a clutch. The driver is informed of the selection carried out in the gearbox by a haptic (tactile) signal at the clutch pedal (7, 70, 700). The signal is transmitted mechanically to the clutch pedal by an electromagnet, or the electromagnet is arranged in the plate (75) of the clutch pedal (7). The signal generator can also consist of an electromagnet connected to a load piston which acts on the pressure line (91) of the clutch-actuating mchanism or of an electropneumatic valve connected to a differential piston signal generator (10).
(FR) Sélecteur de vitesses servocommandé pour une boîte de vitesses (1) de véhicule à moteur et un changement de vitesses commandé par le conducteur par l'intermédiaire de l'actionnement de l'embrayage, le conducteur étant informé de la sélection opérée dans la boîte de vitesses par un signal haptique (tactile) au niveau de la pédale d'embrayage (7, 70, 700). Le signal est transmis mécaniquement sur ladite pédale par un électro-aimant, ou bien ce dernier est agencé dans le plateau (75) de la pédale d'embrayage (7). Le générateur de signal peut également consister en un électro-aimant en liaison avec un piston de pression agissant sur la conduite de pression (91) du mécanisme d'actionnement de l'embrayage, ou bien en une valve électropneumatique en liaison avec un générateur de signal à piston différentiel (10).
