摘要： In an electric braking device that produces brake fluid pressure by driving a second slave piston in the axial direction with the driving force by a motor, a driving force transmission mechanism for transferring the driving force by the motor includes a nut that rotates upon reception of the rotational driving force by the motor, and a ball screw shaft which is engaged with the nut and is movable in the axial direction and which abuts the second slave piston. The electric braking device further includes a worn-out reducer for reducing the worn-out of a contact part between the ball screw shaft and the second slave piston.

摘要： In a vehicle disk brake, a motor housing (46) houses in a housing recess a case (70) into which an end of an output shaft liquid-tightly protrudes, and is mounted to a caliper body (16). A reduction mechanism (35) having an output rotating member (37a) is sealed in the case while part of the output rotating member fluid-tightly protrudes from the case so as to be coaxially and operatively connected to a rear portion of the screw shaft (37). Grease is charged into the case (70). Thus, the case for housing the reduction mechanism is simply configured while preventing leakage of the grease charged into the case, and mounting of the case to the caliper body is facilitated.

摘要： PROBLEM TO BE SOLVED: To properly secure a clearance between a friction member and a braking member. SOLUTION: This brake control device 1 is constituted for controlling an electric brake device for generating braking force by pressing a friction pad 16 to a disc rotor D by supplying an electric current to an electric motor 30. The brake control device 1 has an ECU 20 for operating the electric motor 30 based on a detecting result from a turning angle sensor 93 for detecting an operation quantity of the electric motor 30. The ECU 20 selectively switches ordinary return control for controlling a driving quantity of the electric motor 30 based on the detecting result of the turning angle sensor 93 when controlling to a separating state from a state of pressing the friction pad 16 to the disc rotor D and abnormal time return control for controlling the driving quantity of the electric motor 30 by time from when a current value of an input current supplied to the electric motor 30 becomes a predetermined value or less.

摘要： PROBLEM TO BE SOLVED: To provide heat insulation measures, in which temperature rise in an electric motor, other electric parts, and reduction gear mechanism for reducing driving force of the electric motor is prevented to improve accuracy and durability in working, and to easily implement the heat insulation measures with simple structure and thereby to provide an electric disc brake with excellent assembly property, productivity and maintenability. SOLUTION: The driving force of the electric motor 15 is reduced in a reduction gear mechanism 17 to transmit an advancing/retreating motion mechanism, and lining pads 3, 4 are pressed and slid on a disc rotor 1 by the advancing/ retreating motion mechanism to perform braking. The electric motor 15 is disposed between the lining pads 3, 4 and the reduction gear mechanism 17. Heat insulating members 46 having heat conductivity lower than that of a caliper body 8 is inserted between the reduction gear mechanism 17 and the electric motor 15, and between the electric motor 15 and the lining pad 4 on a reaction portion 12 side.

An outer cylinder member 1 and an inner cylinder member 2 are arranged with a strain space 21 in the actuator 3. The strain gauges 5, 6, 13, 14 are arranged to be fixed on side surfaces of the inner cylinder member 2 and the outer cylinder member 1. A tip end 26 of the input member 25 is inserted inside the inner cylinder member 2. A side wall 30 of the inner cylinder member 2 is extended and a side wall 31 of the outer cylinder member 1 is compressed by the load from the tip end 26. The compression strain of the outer cylinder member 1 and the extension strain of the inner cylinder member 2 can be measured by gauges 5, 6, 13, 14. COPYRIGHT: (C)2011,JPO&INPIT
