Method for monitoring an electromagnetically actuable brake, and vehicle having an electromagnetically actuable brake

In a method for monitoring an electromagnetically actuable brake, which has an energizable coil that interacts with a tractive electromagnet situated so as to be linearly movable, and a vehicle having an electromagnetically actuable brake, the current flowing through the coil is acquired, the acquired current value in particular being conveyed to an evaluation unit, the voltage applied at the coil is intermittently increased, and a relative position of the tractive electromagnet with respect to the coil is determined from the thereby induced current characteristic, in particular the characteristic of the current rise, it is particularly determined from the ascertained position whether the brake is in the applied state or in the released state, the tractive electromagnet in particular is arranged as a permanent magnet or has a permanent magnet.

Brake assembly for robotic surgery system

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.

20220371640 · 2022-11-24 ·

A caster wheel brake system for a mobile support system such as a cart or other wheeled structure is operable to selectively secure caster wheels against rolling rotation. The system includes a caster wheel assembly and a braking mechanism mounted nearby. A pair of brake actuation inputs, such as handles or levers, can be secured to the cart and independently operated to rotate a rotator link, which in turn rotates a brake-actuating link. Rotation of the brake-actuating link deactivates the braking mechanism to allow rolling rotation of the caster wheels. Optionally, the operation of one of the handles to deactivate the braking mechanism has no effect on the other handle.
