Abstract: A parking brake for a wheel rotor having a brake pad associated therewith includes a housing defining first and second passages. First and second pistons are provided in the respective first and second passages. Spindles are threadably connected with each piston. An electromagnetic locking mechanism provided between the spindles having a first magnetic polarity for placing the locking mechanism in a first condition allowing relative rotation between the spindles and the pistons such that the pistons are axially movable within the passages and into engagement with the brake pad in response to hydraulic pressure applied to the pistons. The electromagnetic locking mechanism has a second magnetic polarity for placing the locking mechanism in a second condition preventing relative rotation between the spindles and the pistons such that the pistons remain engaged with the brake pad when hydraulic fluid pressure is removed from the pistons.

Abstract: A fan brake structure includes a fan and a brake device. The fan has a frame body, a fan impeller and a stator. The brake device is disposed under a bottom of a bearing cup. The brake device has a driving member, a brake member and an elastic member. The elastic member abuts against one end of the brake member. The other end of the brake member has a boss body. The driving member has a spiral rail. When the driving member rotates, the boss body moves along the spiral rail, whereby the brake member linearly reciprocally moves upward to brake the fan impeller or linearly reciprocally moves downward to release the fan impeller from the braking.

Abstract: The flywheel device includes a sealed housing section; a rotor located in the sealed housing section where the rotor is held in a vertical position by a magnetic system; a controller coupled to the magnetic system; and a braking annular ring mounted to the sealed housing section below the rotor, where the rotor contacts the braking annular ring when the rotor is lowered or otherwise dropped from the vertical position. The controller performs operations to provide control signals to provide first power to the magnetic system to hold the rotor in the vertical position and provide second control signals to provide second power to the magnetic system to lower the rotor.

Abstract: There is provided a rotary actuator which makes it possible to operate a regulation release of a regulating member from the outside of a case body when the regulating member is in a regulation position, and can prevent an unexpected regulation release, and a robot. A drive mechanism of a joint part has a compression coil spring for biasing a regulation pin toward a regulation position, and a solenoid for moving the regulation pin 32 toward a regulation release position. A through hole is formed in a case body at a portion facing the upper end portion (the other end portion opposite to one end portion abutting against the regulation pin) of a plunger of the solenoid, and the upper end portion of the plunger is positioned on the inside of the case body while the regulation pin is in the regulation position.

Abstract: A brake system for maintaining an angular position of a spindle assembly. A pump-powered motor drives rotation of a spindle on the machine. When no rotation is desired, the spindle will slow, then stop at a desired angular orientation. A rotational sensor will determine the clock position, and a controller compares that to a desired angular orientation. If an error tolerance is exceeded, the motor will rotate the spindle back to the desired orientation.

Abstract: A method for brake lining wear detection is disclosed. The method comprises detecting a wear state of a brake lining installed in the area of a wheel housing and producing a state signal that indicates the wear state. The method also comprises coupling the state signal into at least one electrical line that leads to an evaluation unit for the state signal. The at least one electrical line also transmits at least one other signal from or to at least one other device installed in the area of the wheel housing.
