ABSTRACT:
An electric power booster (12) where driver command is monitored by a transducer (38) on an input rod (34). This signal is converted to the appropriate voltage/current and operates an electric motor (42). The motor output shaft (68) is connected to a planetary gear reducer (72) appropriately sized to provide no more than +/−1/4 turn of an eccentric cam (14). Two master cylinders (16, 18) power piston rods (22, 24) ride diametrically opposed on the cam surface (20). As the cam rotates the piston rods are forced out pressurizing the respective hydraulic circuits and thereby providing fluid to each brake circuit (28, 30). In the event of power failure as well as to augment the output of the motor, the input rod is mechanically linked directly to the cam offset from the center allowing the driver to manually rotate the cam thereby pressurizing the brake circuits.
