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 apparatus for a vehicle according to the present disclosure includes a torque member configured to surround a brake disk, a pair of brake pads disposed in the torque member in a way to face each other, and a plurality of return parts mounted on the pair of brake pads, respectively, coupled with the torque member, and configured to guide movements of the brake pads and return the brake pads to their original positions by elastic restoring forces thereof.

A medical robotic system can include a secondary brake release to allow a user to more easily move the arms of the robotic system when the system is in a power-off or fault state. The robotic system can include a joint and a brake mechanism that can limit motion of the joint. The brake mechanism can include a braking material, a first electromagnetic assembly, and a user-commanded release mechanism. The first electromagnetic assembly can disengage the braking material from an engaged configuration to a disengaged configuration. Further, the user-commanded release mechanism can disengage the braking material from the engaged configuration to the disengaged configuration independent of the first electromagnetic assembly.

A hydrostatic transaxle includes: a casing that is provided with an openable and closable filter insertion port and is filled with hydraulic oil; a hydraulic continuously variable transmission that is arranged inside the casing; a filter holding member that includes a support base that is a hollow cylindrical portion and oil-tightly partitions an inside of a cylinder and an outside of the cylinder, and a filter connection port that is a hollow cylindrical portion extending from a peripheral side surface of the support base and communicating with the inside of the cylinder, the support base communicating the inside of the cylinder to the port, and arranged between the center section and the casing facing the port; and a filter body that is freely inserted to and removed from the casing via the filter insertion port.

Provided is an electric braking device wherein a friction member is pressed, via a piston driven by an electric motor, against a rotary member that rotates integrally with a vehicle wheel, thus generating a braking force on the vehicle wheel. The electric braking device is provided with: a controller for controlling the electric motor; a rotation angle sensor for detecting a rotation angle of the electric motor; and a return mechanism for applying a return force to a piston in a direction away from the rotary member. Furthermore, the controller executes a proper/improper determination to determine whether the return mechanism is operating properly on the basis of a change in the rotation angle after conduction of electricity to the electric motor is stopped.

An overspeed brake system for use in an elevator powerhead is provided. A brake rotor is attachable to a cable drum to rotate with a cable drum. A brake member selectively engages the brake rotor upon transition of an actuation lever from a first position to a second position. A biasing member acts on the actuation lever to bias the actuation lever from the first position towards the second position. A latch arrangement has a first orientation maintaining the actuation lever in the first position and a second orientation releasing the actuation lever for transitioning from the first position to the second position. The latch arrangement transitions from the first orientation to the second orientation when a speed sensing arrangement senses that the rotational speed of the cable drum is at least a predetermined rotational speed.

Methods and corresponding control devices for releasing an electric actuator in a reliable manner, such as an electric parking brake in particular, in a motor vehicle brake system. The aim of the invention is to provide an improved function and architecture which helps prevent the disadvantages of open-loop control systems when using a rationalized sensor system, thereby obviating closed-loop control systems. This is achieved by a release method and a corresponding electronic control unit which obtains an especially modulated change in the power requirement during the release process upon impacting the quasi-elastic release end stop of the electric actuating unit such that the change is fed back, the change being detected in order to be used as information for a power interruption or a termination of the power supply to the electric actuating unit.

The present application relates to crushable body in the form of a corrugated thin walled tube e.g. for use in a piston assembly for engaging two selectively engageable parts. The piston assembly has a housing defining a piston cylinder and a piston. The assembly also has a piston stroke limiter. The piston stroke limiter is configured to limit the length of a return stroke of the piston from an extended stroke position and a retracted stroke position. A crushable body in the form of a corrugated thin walled tube acts between the piston and the piston stroke limiter and is arranged to reduce in axial length when a length of an extended stroke exceeds a length of a retraction stroke to maintain the length of the return stroke.
