Abstract: This electric braking device comprises a linear motion conversion mechanism having a screw shaft caused to rotate by an electric motor, and a nut that moves linearly in response to the rotation of the screw shaft. The electric braking device generates braking force in a vehicle wheel due to a piston coupled to the nut moving linearly within a cylinder and applying pressure to brake fluid. In the electric braking device, a coil spring, of which the extending/retracting direction is the linear motion direction of the piston, is installed in such a state as to be sandwiched between the piston and the screw shaft, so as to be compressed in response to the linear movement of the screw shaft in a direction for reducing braking force and to generate repulsive force against the compression.

Abstract: An electric brake control apparatus includes: a clamping force acquisition unit configured to acquire a clamping force generated by moving a piston toward a pad through rotation of a motor; a lower-limit clamping force acquisition unit configured to acquire a minimum value of the clamping force required to maintain a stopped state of the rotor; an upper-limit clamping force acquisition unit configured to acquire a maximum value of the clamping force to move the piston away from the pad through a power of a power supply while maintaining the stopped state of the rotor, based on a state of a power supply; and a clamping force control unit configured to control the motor such that the clamping force is confined between the minimum value and the maximum value.

Abstract: An electric actuator includes an input member that is rotationally driven by the electric motor and includes a first rotation stop part on an inner periphery, an output member that includes a second rotation stop part engageable with the first rotation stop part, and a first screw part on an outer periphery, and a linear motion member that includes a second screw part engageable with the first screw part. Both the screw mechanism and the rotation-stop mechanism are formed on the outer periphery of the output member. Therefore, in the electric actuator, the radial and axial dimensions are shortened.

Abstract: A mount member is fixed to a support member by first and second fastening members, and a caliper is mounted to the mount member by first and second guide members. A motor axis of an electric motor and an axis of a shaft member configured to press a pressing member are different from each other. The electric motor is fixed to the caliper. When viewed from an axial direction of the first guide member, the motor axis is positioned inside a fastening quadrangle having four corners corresponding to positions of respective axes of, and is perpendicular to the axis, and the motor axis is orthogonal to a plane of the fastening quadrangle. As a result, there may be provided a vehicle electric braking device in which an axial direction dimension may be reduced to suppress an amplitude caused by vibration, and components sensitive to vibration influence are appropriately arranged.
