In an approach to interlock braking, one or more driving wheels and one or more driven wheels are engaged to rotate in the same first direction. One or more braking wheels are driven by a power transmission mechanism associated with the one or more driving wheels. A first braking surface, associated with the one or more driven wheels, and a second braking surface, associated with the one or more braking wheels, engage. A braking force is generated by the engagement of the first braking surface and the second braking surface, and transmitted by the power transmission mechanism to the one or more driving wheels.

An assembly for an electromechanical brake of a vehicle having a caliper assembly driven by a motor includes a cup gear or a drive disk for receiving torque from the motor and transferring the torque to a spindle. A piston is coupled to the spindle or a ball ramp and moves axially relative to the spindle in response to rotation of the spindle to brake the vehicle during a braking operation. A force sensor is aligned with the spindle and cup gear for sensing a reaction force applied to the piston during the braking operation. A thrust bearing is provided for transferring the reaction force from the cup gear to the force sensor.

A ball ramp actuator assembly including a control ring, an activation ring including a first section and a second section, two circumferential plate grooves formed between the control ring and the sections of the activation ring which contain rolling elements, two clutches, a gear and an actuator. The first and second sections are splined together allowing for axial movement. The first clutch is connected to the first section of the activation ring and a second clutch is connected to the second section of the activation ring. The rotation of a section of the activation ring axially in one direction allows the corresponding plate groove to expand and apply a load to the corresponding clutch while the other section of the activation ring remains inactive and rotation in the opposite direction activates the other clutch respectively.

In an approach to interlock braking, one or more driving wheels and one or more driven wheels are engaged to rotate in the same first direction. One or more braking wheels are driven by a power transmission mechanism associated with the one or more driving wheels. A first braking surface, associated with the one or more driven wheels, and a second braking surface, associated with the one or more braking wheels, engage. A braking force is generated by the engagement of the first braking surface and the second braking surface, and transmitted by the power transmission mechanism to the one or more driving wheels.

A device for a brake system comprises a rotating plate including magnets having a first polarity. The rotating plate engages an output shaft of a motor. The device includes a non-rotating plate including magnets, one or more of which have the first polarity and one or more of which have a second polarity. The non-rotating plate moves axially between an engaged position and a non-engaged position. In the engaged position, the magnets in the rotating plate magnetically attract the one or more magnets in the non-rotating plate with the second polarity so that non-rotating plate moves into contact with the rotating plate. In the non-engaged position, the magnets in the rotating plate magnetically repel the one or more magnets in the non-rotating plate with the first polarity so that the non-rotating plate moves out of contact with the rotating plate and thus rotation of the rotating plate is allowed.

The present invention is directed to an electromechanical brake device for securing the structural reliability and improving the stability even when overloading. The electromechanical brake device configured to brake by pressing a disk-shaped disc, which is rotated with motor vehicle wheels, with a pair of friction pads, and including a piston unit configured to move the friction pads in a direction of the disc, including: an internal shaft connected to an external motor so as to rotate when the motor is driven; an external shaft, in which an end of the internal shaft is inserted, configured to rotate together when the internal shaft is rotated, and to which the piston unit is connected so as to move in the disc direction; and a load control unit provided between the internal shaft and the external shaft, so that the external shaft is rotated together when the internal shaft is rotated, and the internal shaft and the external shaft are rotated at different speeds when a load of a predetermined value or more is applied between the internal shaft and the external shaft.

An electronic control clutch structure of an actuator device having a driver, a cam, a clutch wheel, and a transmission wheel is provided. The cam is connected to the driver, is driven by thereof, and includes a first actuating portion and a second actuating portion. The clutch wheel is connected to the rotating draft, rotates with thereof, and is arranged atop on the cam. The cam operatively actuates the clutch wheel. The transmission wheel is connected to the rotating draft. The clutch wheel and the transmission wheel are in a detached state when the clutch wheel is located on the first actuating portion. The clutch wheel and the transmission wheel are in an embedded state when the clutch wheel is located on the second actuating portion. The electronic control clutch structure may adapt uneven areas in the grass to perform weeding work according to the terrain changes of the grassland.

A robotic surgery cart has a pair of rear wheel assemblies and a pair of front wheel assemblies. A brake assembly for the robotic surgery cart includes a gearbox interposed between and connected to the pair of rear wheel assemblies by rotatable shafts. Elongate actuators extend between and interconnect the rotatable shafts and brake mechanisms for the front wheel assemblies. A pedal lever is rotatably coupled to the gearbox and can rotate clockwise by pressing one portion of the pedal lever and can rotate counterclockwise by pressing another portion of the pedal lever. Rotation of the pedal lever causes the gearbox to rotate the rotatable shafts to substantially lock the pair of rear wheel assemblies, and substantially simultaneously causes a translation of the elongate actuators to actuate the brake mechanisms of the front wheel assemblies, such that the wheels of the front and rear wheel assemblies brake substantially simultaneously.
