Title:
ELECTRICALLY ACTUATED BRAKE DEVICE
Document Type and Number:
Japanese Patent JP3909021
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve the responsibility when changing brake force in an electrically actuated brake device.
SOLUTION: The electrically actuated brake device consists of a brake piston 17 for moving a brake pad 19 in the direction of an axis L and a first and a second electric motors 36 and 37 connected via a screw mechanism 58. The screw mechanism 58 is provided with a first screw member 21 and a second screw member 28 engaged with each other. The first screw member 21 is rotatably supported with respect to a brake caliper 11, and jammed in the direction of the axis L. The second screw member 28 is relatively rotated with respect to the first screw member 21 so that the second screw member 28 is moved toward the direction of the axis L with the brake piston 17 and the brake pad 19. The brake pad 19 is made to approach, stop and detach only by changing the rotational speed with good responsibility with respect to a brake disk 14 so that the braking force can be controlled to increase, maintain and reduce without stopping or reversing the rotation of both screw members 21 and 28.
