  • Patent number: 10612610
    Abstract: An electromagnetic brake is provided in which short duration current pulses move the brake between engaged and disengaged states. A first current pulse having a first polarity is delivered to a conductor within a field shell when the brake is engaged and establishes an electromagnetic circuit including the field shell and an armature plate that urges the armature plate away from a rotating friction plate and towards the field shell to disengage the brake. A magnetic circuit is maintained after termination of the first current pulse due to a remanence in at least one of the armature plate and the field shell. A second current pulse having a second polarity opposite the first polarity delivered to the conductor when the brake is disengaged weakens the magnetic circuit thereby allowing a spring to move the armature plate away from the field shell and towards the friction plate to engage the brake.

  • Patent number: 10316907
    Abstract: A brake apparatus stops a rotor of an external-rotor motor that drives the head or a joint of a home robot. Frictional torque is generated when a friction pad presses a rotor surface even when a power source is switched off. A posture of a moving part, such as the head, of the robot is not abruptly disturbed even though the power source is switched off. Since a light external force is applied to the moving part of the robot in the off state of the power source, a motion in a direction desired by the user takes places without being stiff. The motion of the head of the robot stops when the external force is removed. An intention of the user who touches the robot may be satisfied even when the power source of the robot is switched off.

  • Patent number: 8657096
    Abstract: A door machine having an electric motor and a chain disk locking mechanism. The chain disk locking mechanism includes a chain disk, an engaging rotary block, a stationary shaft and a plurality of moving pins. When the chain disk is pulled to rotate, the fixed pins of the chain disk press the moving pins so as to push the engaging rotary block to rotate with the stationary shaft together. When the stationary shaft is pulled to rotate, the engaging rotary block prohibits the moving pins from rotation. When the chain disk is pulled manually, the rolling door can be rolled upward or downward; when cease pulling the chain disk, braking is immediately effected so as to prevent the rolling door from moving upward or downward. Hence, the clutch mechanism can be omitted for cost saving and the structure of the mechanism can be simplified.

  • Patent number: 8636117
    Abstract: A safety stop is provided for stopping a movable member having at least one set of opposed wheels for gripping a rail. The stop has a track on each of opposite sides forming a wedge shape of a narrow end progressively widening to a wide end in a direction of travel of the movable member. With the opposed wheels of the movable member respectively at opposite sides of the wedge shape member, the tracks of the wedge shape member engage and impart a spreading strain to the opposed wheels as the movable member moves in the direction of travel. The opposed wheels of the movable member comprise a deformable material to absorb the kinetic energy of the movable member. The tracks of the stop additionally may have undulating features comprising concave and convex surfaces in the direction of motion.

  • Patent number: 8596427
    Abstract: An output shaft of a motor is divided into a front shaft (first or second front shaft) and a rear shaft. The first front shaft is to be rotatably supported by a first shaft support plate connected directly to a motor housing. The second front shaft is to be rotatably supported by a second shaft support plate connected to the motor housing with a spacer provided between the second shaft support plate and the motor housing. A braking mechanism including a flange plate, a braking member and a biasing member is mounted to the second shaft support plate and the second front shaft. The first front shaft is used with the first shaft support plate to realize a power tool without the braking mechanism. The second front shaft is used with the second shaft support plate and the spacer to realize a power tool without the braking mechanism.

  • Patent number: 8550219
    Abstract: Disclosed is an electromagnetically released spring pressure brake that is to be mounted on a machine wall or similar. Said brake comprises a uniform rectangular coil support (1) with two preferably oval, adjacent coils (7, 7.1), to which two separately movable rectangular armature disks are assigned. Said armature disks apply pressure to a joint rotor encompassing two friction linings that are mounted on each side when the coils (7, 7.1) are de-energized. The rotor is axially movable on an axially toothed hub. Two respective fastening screws (9) are used for guiding each of the armature disks parallel along the central longitudinal axis (13, 13.1) thereof, on the radially largest possible diameter of the rotor. A manual lever (10) featuring manual releasing bolts is provided for each armature disk.

  • Patent number: 8534431
    Abstract: A braking mechanism is provided for a hydraulic motor driven wheel utilizing a two-piece design of a hub that rotates by means of a drive shaft. A hydraulic chamber is created on the hub in which a piston resides. The piston is grounded (i.e., non-rotatable relative to the motor housing) in the sealed chamber. The piston face inside of the chamber has a radial set of face teeth. These face teeth are similar to the face teeth inside of the hydraulic chamber. When the chamber is pressurized, the piston face teeth are pushed away from the hub face teeth allowing the hub to freely rotate. When pressure is released from the chamber, a spring, or a number of springs, push the piston into the hub causing it to stop rotating relative to the piston.

  • Patent number: 8528707
    Abstract: Disclosed is a disc brake for a vehicle, such as an electronic wedge brake, capable of preventing a disc from being subject to the moment due to misalignment of inner and outer friction members with respect to a disc. The disc brake includes a disc rotating together with a vehicle wheel, inner and outer friction pads disposed at both sides of the disc, respectively, a wedge unit installed at rear sides of the inner and outer friction pads to press the inner and outer friction pads against the disc, a driving device that operates the wedge unit for a braking operation, and a sync member for synchronizing braking positions of the inner and outer friction pads with respect to the disc. Since the disc is prevented from being subject to the moment, uneven wear does not occur in the friction member and/or the disc and deformation of the disc is prevented.

A brake element, which is connected displaceably to one of the bearing rings, is pressed against an opposite surface connected to the associated other bearing ring in order to produce a braking effect by frictional engagement and the frictional engagement can be cancelled by means of an electromagnet. The brake element is arranged as an integral bearing component inside one of the bearing rings and is pressed against the opposite surface by means of a spring force. The spring force is variably settable and the electromagnet includes one of the bearing rings as a soft-iron core and a coil enclosing the latter.
