Patent number: 10316907Abstract: 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.Type: GrantFiled: November 29, 2017Date of Patent: June 11, 2019Assignee: NEDEC Co., Ltd.Inventor: Sang Sun Kang

The rail brake includes a braking plate having friction material, a spring package in communication with the braking plate, a hydraulic cylinder, a piston housed at least partially inside the hydraulic cylinder, and a brake controller. The braking plate is selectively movable relative to the guide rail, and the spring package biases the friction material to interact with the guide rail to cause braking. The piston is in communication with the braking plate and is selectively: (a) movable in a release direction to diminish or overcome force from the spring package; and (b) movable in an engage direction to supplement the force from the spring package. The brake controller selectively causes the piston to move in the release direction and in the engage direction.Type: GrantFiled: January 30, 2015Date of Patent: August 22, 2017Assignee: THYSSENKRUPP ELEVATOR AGInventors: Frank P. Dudde, Peter F. Feldhusen, William K. Delk, Mike Palazzola, Jie Xu, Alan M. Parker, John Keith Anderson, Olivia Stone

Patent number: 9638272Abstract: The invention relates to an electromagnetic brake and a method for making an electomagnetic brake. The electromagnetic brake comprises a frame part, an armature part movably mounted on the frame part and having a magnetic core, one or more spring elements for activating the brake by moving the said armature part forwards, an electromagnet fitted to the frame part and arranged to release the brake by pulling the said armature part backwards by resisting the said one or more spring elements, and a planar, elastically bendable damping plate fitted to be bent when the armature part is moving and, while being bent, to produce a damping force resisting the bending to dampen brake noise.Type: GrantFiled: October 25, 2013Date of Patent: May 2, 2017Assignee: Kone CorporationInventors: Mika Olkkonen, Antti Saarelainen

Patent number: 9592813Abstract: Disclosed is an assembly that includes a spindle; a brake cable in communication with the spindle; and a spring in communication with the spindle. Movement of the spindle in a first direction causes the brake cable to move so that a clamping force is created. Movement of the spindle in a second direction causes the brake cable to move in a second direction so that the clamping force is released. Movement of the spindle in both the first direction and the second direction causes the spring to compress so that a controller can determine when the clamping force is created and released.Type: GrantFiled: June 25, 2015Date of Patent: March 14, 2017Assignee: AKEBONO BRAKE INDUSTRY CO., LTDInventor: Galus Chelaidite

Patent number: 9369026Abstract: The present invention provides a motor having a braking function and used in a linear actuator. The motor includes a main body, a rotation shaft, a braking means and a stopping means. The rotation shaft penetrates the center of the main body. The braking means includes a braking ring and a helical ring. The braking ring includes a plurality of curved plates. The helical ring surrounds outer edges of the curved plates. Each curved plate is put on the outer periphery of the rotation shaft. The stopping means is disposed between the main body and the braking means for restricting the rotation of any of the curved plates. By this arrangement, a better braking and decelerating function can be achieved.Type: GrantFiled: March 25, 2012Date of Patent: June 14, 2016Assignee: TIMOTION TECHNOLOGY CO., LTD.Inventor: Chou-Hsin Wu

Patent number: 9328844Abstract: A detent mechanism is provided for a sliding valve which includes a valve slide that is accommodated within a valve housing and is linearly movable relative to a longitudinal axis. The detent mechanism has a linearly movable detent element configured to engage at least one detent notch. The detent notch is coupled with the valve slide such that when the detent element is locked into the detent notch, said valve slide is fixed along the longitudinal axis. A first spring prestresses the detent element in a direction of the detent notch. The detent element includes a permanent magnet or a ferromagnet and the detent mechanism includes an electric coil configured to generate a magnetic field. The detent element is configured to be moved in opposition to the prestressing force of the first spring and out of engagement with the detent notch via the magnet and magnetic field.Type: GrantFiled: May 24, 2013Date of Patent: May 3, 2016Assignee: Robert Bosch GmbHInventors: Davide Pingani, Luca Rovacchi, Vincenzo Bollero, Loris Rosselli

Patent number: 9240269Abstract: The invention relates to a solenoid actuator, consisting of a magnet body (1), a magnet armature, a cover (3) closing the space in which the magnet armature travels back and forth, at least one electric coil (4), which is arranged in the magnet body (1) concentrically around the axis of travel of the magnet armature, and means (5) for power transmission, which are in operative connection with the magnet armature and protrude out of the solenoid actuator. According to the invention, the magnet armature of the solenoid actuator is an axially guided annular magnet armature (2), and the means (5) for power transmission are arranged coaxially around the axis of travel of the annular magnet armature (2). This has the advantage that the solenoid actuator allows long switching paths and a small construction, along with high tightening and holding forces.Type: GrantFiled: September 17, 2012Date of Patent: January 19, 2016Assignee: BISCHOFF TECHNOLOGIE-MANAGEMENT GMBHInventors: Hans-Joachim Polack, Hartmut Bischoff
