摘要： An object of the present invention is to provide an electric disc brake apparatus having a simple constitution in which the operating condition of a parking brake can be reliably detected. A controller detects the operating condition (steps S25, S26) of a solenoid for driving a parking brake locking mechanism (holding mechanism) by means of a motor current (step S24). As a result, a state in which thrust generated by the motor (first electric actuator) is maintained by the parking brake locking mechanism, and accordingly the operative and inoperative states of the parking brake can be understood easily. Further, detection of the motor current is performed using a current sensor that is also used to realize a function of the motor (a function for moving brake pads toward a disc rotor), and hence separate current detection means need not be provided. Accordingly, the operative or inoperative state of the parking brake can be understood by means of a simple constitution, enabling a reduction in the cost of the apparatus.

摘要： A brake fluid pressure control system includes an external source of fluid pressure, a wheel cylinder, and a fluid pressure control valve disposed between the external source of fluid pressure and the wheel cylinder. A controller is operable to control the fluid pressure control valve whereby fluid pressure under control is fed from the external source of fluid pressure to the wheel cylinder. When a change in pressure within the wheel cylinder occurs, a fail safe valve is operable to disconnect the wheel cylinder from the fluid pressure control valve and instead, connect the wheel cylinder to a master cylinder. Inspection of the fail safe valve is carried out by disconnecting the wheel cylinder from the control valve when no brake is applied, feeding fluid pressure from the external source of fluid pressure to the wheel cylinder, and detecting a change in pressure within the wheel cylinder. An alert device is provided to give a warning in the event of a system failure.

摘要： A piston is slidably fitted in a cylinder for dividing the interior of the cylinder into upper and lower cylinder chambers. A reservoir is connected to the piston. A primary passage communicates between the upper cylinder chamber and the reservoir. The primary passage includes a primary damping valve. A secondary passage is connected to the primary passage to bypass the primary damping valve. A constant orifice, a filter, and a damping force adjusting valve are provided in the secondary passage. The primary damping valve includes a pilot line. The pilot line is connected downstream of the filter. The flow resistance of the damping force adjusting valve is directly adjusted by changing the cross sectional flow area of the damping force adjusting valve. The valve opening pressure of the primary damping valve is adjusted by changing the pilot pressure introduced from the pilot line. When the filter becomes clogged, the primary passage ensures the flow of the hydraulic fluid. The pilot pressure is then lowered so that the valve opening pressure of the primary damping valve is lowered to keep the damping force suitably low.

摘要： Two shim plates provided for a friction pad are arranged to be slidable relative to each other in the circumferential direction of a disk, thereby suppressing the transmission of rotational force from the disk to a caliper through the friction pad and so forth during a braking operation. A friction pad including a lining and a backing plate is disposed between the disk and an outer leg portion of the caliper. An inner shim plate is integrally mounted on the back of the backing plate. An outer shim plate is disposed between the inner shim plate and the outer leg portion of the caliper in such a manner as to be slidable relative to the inner shim plate in the circumferential direction of the disk. During a braking operation, when the friction pad pressed by the caliper is circumferentially displaced by being dragged by the disk, the inner shim plate, together with the friction pad, slides relative to the outer shim plate, thereby reducing rotational force transmitted from the disk to the caliper.

摘要： A robot control apparatus does not require an expert to perform programming, prepare teaching data or reprogram the motions of a work robot. The controller for the robot accepts the teaching point instructed by a beginner operator, and computes the start and end points in a track from the input teaching points. The controller also computes target start and end points in each of the passes in the track based on the current track points and the overspray width input by the operator and automatically allows for the overspray width. The control apparatus therefore facilitates operation of painting tasks which conventionally required a labor-intensive effort in reprogramming by an expert operator.

摘要： A disc brake includes a carrier with a pair of axially and outwardly extending arms. A pair of pad springs are mounted to the inner side of the arms. Each of the pad springs has a pair of return springs. The return springs extend radially of a rotor and have respective projections. Each of the return spring is made by bending an elongated tongue. A pair of backing plates are attached to a corresponding pair of friction pads and have lugs. A wear warning element is attached adjacent to the lug of each backing plate and has a bent portion. Each of the projections is resiliently in contact with the inner side of the bent portion so as to constantly urge the backing plate and the friction pad in a direction away from the rotor.

摘要： The present invention provides a suspension control apparatus including dither amplitude setting device which is adapted to set the amplitude of the dithering current to be superimposed on the command current is set to a small value in a region in which a damping force generated by the shock absorber changes at a high rate relative to changes in intensity of the current applied to the solenoid. The present invention also provides a suspension control apparatus including dither frequency setting device which is adapted to set the frequency of the dithering current to a high frequency in a region in which a damping force generated by the shock absorber changes at a high rate relative to changes in intensity of the current applied to the solenoid and set the frequency of the dithering current to a low frequency in a region other than the above-mentioned region. The suspension control apparatus of the present invention prevents generation of undesirable noise and vibration while suppressing an increase in hysteresis with respect to a damping force.

摘要： A piston is slidably fitted in a cylinder for dividing the interior of the cylinder into upper and lower cylinder chambers. The upper cylinder chamber communicates with the lower cylinder chamber through a check valve. The lower cylinder chamber communicates with a reservoir through a check valve. The upper cylinder chamber communicates with the lower cylinder chamber through an extending side damping valve. The lower cylinder chamber communicates with the reservoir through a contracting side damping valve. A piston rod is connected to the piston. When the piston rod is in an extending stroke, a damping force is generated by the extending side damping valve. When the piston rod is in a compressing stroke, a damping force is generated by the contracting side damping valve. The reservoir includes a connecting hole having an opening. A baffle plate is provided within the reservoir and above the opening of the connecting hole. Arrangement of the baffle plate above the opening of the connecting hole defines an entrance portion through which hydraulic fluid flows from the connecting hole to the reservoir. The cross sectional flow area of the entrance portion is gradually expanded, thereby decreasing the flow velocity of the hydraulic fluid to restrain generation of eddies to prevent cavitation and aeration.
