    摘要: 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.

    摘要: A toothed safe braking apparatus for use in robotic joint, comprising an electromagnetic telescoping apparatus (6) and a friction engagement component (10). The friction engagement component (10) is mounted on a shaft (C) of the robotic joint and comprises a brake lock ring gear (1) provided with a first center fitting hole (12), the brake lock ring gear (1) being provided with teeth (11) arranged on the outer circumferential surface thereof, a pretension ring (2) provided with a second center fitting hole (13), and a brake hub (4) provided with a first end surface (14), a second end surface (15), and an outer circumferential surface (16). On a locked position, a working bit (17) of the electromagnetic telescoping apparatus (6) can be engaged with the teeth (11) on the brake lock ring gear (1) of the friction engagement component (10); and, on an unlocked position, the working bit (17) of the electromagnetic telescoping apparatus (6) can be disengaged from the teeth (11) on the brake lock ring gear (1) of the friction engagement component (10). The brake lock ring gear (1) and the pretension ring (2) are arranged in parallel via the first fitting hole (12) and the second fitting hole (13) to be friction engaged on the outer circumferential surface (16) of the brake hub (4).

    摘要: 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.

    摘要: Provided are an electromechanical brake and a vehicle including the same. An electromechanical brake according to an embodiment of the present disclosure includes a first brake pad and a second brake pad configured to respectively press a front surface and a rear surface of a disc and includes a housing having one side to which the first brake pad is coupled, a carrier to which the second brake pad is fixed, the carrier being coupled to the housing so that the second brake pad advance or retreat toward the disc, a hollow motor installed on the housing and configured to provide rotational driving power, the hollow motor having an internal space penetratively formed in a direction in which the rotation axis extends, a rotary screw extending and disposed in the internal space, the rotary screw being configured to rotate about the rotation axis of the motor, a power train coupled to a rear side of the motor and configured to transmit the rotational driving power of the motor to the rotary screw, and a nut coupled to the rotary screw and configured to advance or retreat toward the second brake pad.
