摘要： 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.

摘要： In an electric brake of the present invention, a plunger of an actuator is connected through a pin to a pivot arm to which an engaging pawl engageable with a tooth portion of a ratchet is pivotably attached. A lower surface (a force-receiving portion) of the pin is adapted to receive an upward force which is applied by a tool inserted through a bolt hole threadably engaged with a watertight bolt. When the parking brake is operated (the engaging pawl is engaged with the tooth portion of the ratchet), if supply of current to the coil becomes impossible, the pin is moved upward by means of the tool, to thereby separate the engaging pawl from the tooth portion. Therefore, an emergency action to release the parking brake can be manually conducted.

摘要： In an electric booster according to one embodiment of the present invention, a brake pedal is connected to a sun gear of a differential transmission mechanism corresponding to a planetary gear mechanism. An electric motor is connected to a ring gear, and an output rod is connected to a planetary carrier, and the output rod is connected to a piston of a master cylinder. When the brake pedal is operated to rotate the sun gear, planetary pinions rotate and revolve around the sun gear. As a result, the planetary carrier rotates to move the output rod forward to push the piston. As a result, a hydraulic pressure is generated in the master cylinder. At this time, the electric motor is controlled according to the rotation of the sun gear to rotate the ring gear so that the ring gear follows the sun gear. In this manner, a servo force of the electric motor is applied to the rotation of the planetary carrier.

摘要： A motor-driven disk brake is capable of functioning as a parking brake satisfactorily without degrading the brake operating feeling and impairing the function of operating as a motor-driven brake. A stator and rotor of an electric motor are provided in a caliper body floatably supported on a carrier. The rotation of the rotor is transmitted to a piston after being converted into rectilinear motion through a ball-and-ramp mechanism and an adjusting nut. The piston, together with a claw member, presses brake pads against a disk rotor. A rotation assisting device is provided between the rear end of the rotor and a motor casing. A rotary disk constituting the rotation assisting device is rotated through a wire extending from an external operating member.

摘要： A motor-driven disk brake having a caliper containing a piston for pressing a brake pad, a rotary actuator and a rotary-to-rectilinear motion converting mechanism for transmitting rotation of the rotary actuator to the piston after converting it into rectilinear motion. The piston is driven in response to rotation of the rotary actuator to press the brake pad against a disk rotor, thereby generating braking force. A brake releasing mechanism for returning the rotary-to-rectilinear motion converting mechanism to its initial position in the event of a failure in the rotary actuator is interposed between a rotating member and a rectilinearly moving member that constitute the rotary-to-rectilinear motion converting mechanism. The brake releasing mechanism has an urging device for generating a torque in the direction for returning the piston in response to the rotation of the rotating member in the direction for advancing the piston. The urging device generates a torque greater than the rotational resistance of the rotating member of the rotary-to-rectilinear motion converting mechanism.
