Title
(EN) VALVE UTILIZING SHAPE MEMORY ALLOYS AND AN ANTI-LOCK BRAKE SYSTEM WITH THE VALVE
(FR) ROBINET UTILISANT DES ALLIAGES A MEMOIRE DE FORME ET LIMITEUR DE FREINAGE LE COMPORTANT
Abstract
(EN)
A valve (actuator) for performing pressurization, decompression and pressure maintenance drives plural spools movable up and down within a housing having plural bores by using linear shape memory alloys, and an anti-lock brake system utilizes the valve, in which respective bores have inlets and outlets, a mechanism for holding a lowering state of the spools is installed to the lower portion of the housing, and the spools return to their original positions by bias springs. A master cylinder, a wheel brake and a hydraulic pump are connected to the inlets and outlets of the valve of the anti-lock brake system and an electronic control unit is connected to the shape memory alloys to actuate the shape memory alloys, thereby attaining the operations of pressurization, decompression and pressure maintenance in connection with a brake pressure of the wheel brake.

Robinet (actionneur) assurant la mise sous pression, la détente et l'entretien de la pression, et entraînant plusieurs tiroirs montés mobiles dans le sens vertical dans un carter à plusieurs alésages, à l'aide d'alliages à mémoire de forme linéaire, et limiteur de freinage le mettant en oeuvre, dans lequel les alésages respectifs présentent des orifices d'entrée et de sortie, un mécanisme de maintien des tiroirs en position baissée est monté dans la partie inférieure du carter, et les tiroirs sont ramenés à leurs positions initiales par des ressorts de sollicitation. Un maître-cylindre, un frein de roue et une pompe hydraulique sont reliés aux orifices d'entrée et de sortie du robinet du limiteur de freinage, et une unité de commande électronique est raccordée aux alliages à mémoire de forme pour les actionner, de manière à effectuer les opérations de mise sous pression, de détente et d'entretien de la pression, en association avec la pression de freinage du frein de roue.
