SYSTEME DE FREINS A SERVOFREIN ELECTRIQUE |
摘要 |
<p>Brake system comprising a thrust rod (130) driven by the servobrake (200) and actuating the piston (110) of the master cylinder (100), the servobrake (200) being linked by a hydraulic actuator (270) to the control rod (230) of the brake pedal (PF). The servobrake (200) comprises an actuator piston (220) controlled by an electric motor (265) via a rack drive (260). A simulator chamber (250) delimited by the hydraulic actuator (270) is subdivided by an intermediate piston (240) into a rear volume (V1) and a front volume (V2), respectively delimited by the intermediate piston (240). A duct (L1) links the rear volume (V1) to a duct (L2) linked to the front volume (V2) by a first solenoid valve (EV1) and the duct (L2) to the tank (115) by a second solenoid valve (EV2). The piston (240) is linked to the rod (130) bearing an abutment (132) to be thrust by the actuator piston (220).</p> |
