A braking system for a rotating member has a lever with an apex where a first arm meets a second arm. The apex is rotationally secured to a support. A band wraps around the circumference of an end of the rotating member. A first end of the band is secured to the support. A second end of the band is secured to the second arm. A resilient member is secured to the first arm and the support. An actuator is secured to the first arm. The resilient member biases the first arm, placing the band in frictional engagement with the circumference of the rotating member, and activation of the actuator directs the first arm, which relieves the frictional engagement of the band with the circumference of the rotating member. The actuator may be connected to a throttle or a brake control.

A brake actuator (1, 1′) includes a casing (10), an electric motor for providing a driving torque, a cam disc (20) rotatably mounted to the casing (10) and operatively coupled to the electric motor, and a push rod (30) received in the casing (10), and configured to reciprocate in a longitudinal direction (100) between a retracted position (300) and an extended position (400). The push rod (30) and the cam disc (20) are operatively coupled such that a rotational movement of the cam disc (20) causes a linear movement of the push rod. A guiding member (40), in particular a bushing, is mounted to the casing (10), wherein the guiding member (40) guides the movement of the push rod (30) in the longitudinal direction (100).

Mechanisms to realize lightweight rotational joints having passive, high torque braking in one or more degrees of freedom are presented herein. In addition, robotic systems incorporating one or more rotational joints with passive, high torque braking as described herein are also presented. Each degree of freedom includes a spring element to preload the braking assembly to maintain high torque braking. The force generated by the spring is multiplied to a much larger force applied to the braking elements by a lever structure and an eccentric mechanism. A human user manually displaces the spring element and effectively reduces braking torque to a desired amount. In a further aspect, a two degree of freedom mechanical shoulder joint and brake device is disposed in a structural path between the harness assembly of an upper body support system and a surface of a working environment.

A power tool comprises a motor, a final output shaft, a tool body, a detection device, and a braking device. The motor has a motor body including a stator and a rotor, and a motor shaft extending from the rotor and being rotatable around a first rotational axis. The final output shaft is configured to be rotationally driven around a second rotational axis by torque transmitted from the motor shaft. The tool body houses the motor and the final output shaft. The detection device is configured to detect a locking state of the final output shaft. The braking device is configured to directly act on the motor shaft to brake the motor shaft in response to detection of the locking state.

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.

An axle disconnect assembly, including: a housing; a shaft; a sleeve non-rotatably connected to the shaft and including teeth; a shift assembly; and at least one resilient element directly connected to the shift assembly. In a first blocked mode, the teeth of the sleeve contact the power output without meshing with teeth of the power output, the shift assembly deflects the at least one resilient element to at least one first shape, and the at least one resilient element urges the sleeve against the power output. In a second blocked mode, the teeth of the sleeve are meshed with the teeth of the power output, a force blocks disengagement of the sleeve from the power output, the shift assembly deflects the at least one resilient element to at least one second, and the at least one resilient element urges the sleeve away from the power output without displacing the sleeve.
