Abstract: An electric braking apparatus is disclosed in which a rotational movement from a motor is converted into linear movement that moves a brake piston to generate braking force. The electric brake apparatus can perform full parking brake function without sacrificing its original braking function. In operation, immediately after generation of braking force caused by rotation of the rotor 26, supply of electricity to the motor is turned off. After supply of electricity is turned off, however, the rotor 26 is restricted from returning to its original position due to an engagement with an engaging claw 54 via a claw wheel 50, thereby keeping the barking brake remain effective. When electricity is thereafter supplied to the motor, the rotor 26 generates rotational torque sufficiently strong to push down the engaging claw 54 for disengagement, thereby releasing the parking brake.

As the toggle lever extends, it pushes the brake pad closer to the surface to be slowed. Multiple toggle levers may be used to distribute the force across the brake pad. This configuration allows a single input from the incline to actuate both toggle levers. By adjusting the width of the incline actuating the toggle lever, the force on the brake pad may be adjusted.

Abstract: In a disk brake, a first surface of a wedge member is in line contact via a first roller bearing with a surface of the piston and a second surface of the wedge member is also in line contact via a second roller bearing with a surface of the guide member. Each of the first surface of the wedge member and the surface of the piston is perpendicular to a piston axis and each of the second surface of the wedge member and the surface of the guide member is inclined by a given angle to the piston axis. When a drive unit moves the wedge member substantially perpendicularly to the piston axis, the piston moves axially and presses a frictional material against a disk. Since force transmitted from the wedge member to the piston acts parallel to the piston axis with a less moment in a direction of pressing the piston against a wall surface of the cylindrical bore so that the piston moves smoothly.

A flat surface (56c) is formed on the periphery of the sleeve and the detecting head (80) of the displacement detection apparatus detects the rotation of the sleeve (56).
