Brake activator Yu eta

(57) to the brake actuator to perform a braking operation by [Abstract] OBJECTIVE electrical signal, incorporating the mechanical brake actuation mechanism by electrical uncontrollable it can operate the brake actuator even when the braking force disappears, the brake actuator safety to improve. [Configuration] When an electrical failure occurs lever 18 rotates in the direction perpendicular to the drawing by rotating the shaft 19 the ball ramp mechanism 17 There connecting actuated clutch 16. Furthermore shaft 1 in this state 9 rotates Continued rotation gear 14, the rotation of the screw 9, and slides in the cylinder of the nut 7 the piston 6, the nut 7 is moved to the right in the figure the sleeve 10 strikes the piston bottom. Furthermore nut 7 in this state the brake pads 2 and 3 applies a braking force to the rotor clamp the rotor 4 moves rightwards.
