A spring applied, hydraulically released brake includes a housing having an open end adapted to align with a vehicle surface and an internal ring extending from an inner perimeter of the housing; a piston; a disc stack including a thicker stationary disc including a tab with a hole therethrough, the hole receiving a slotted spring pin, the slotted spring pin slidably receiving a pin spring over a portion thereof; and a spring assembly adapted to urge the piston into contact with the thicker stationary disc to establish a default position of the brake; where, in a released position of the brake, the piston is not in contact with the thicker stationary disc, and the pin spring urges the thicker stationary disc into contact with the internal ring of the housing to thereby prevent the thicker stationary disc from free floating.

A caster wheel brake system for carts and other wheeled articles is operable to secure caster wheels against rolling rotation along their horizontal rotation axes. The system includes a pivotable parking brake lever, an actuator arm, and a torque shaft extending between the brake lever and actuator arm. The brake lever includes a distal end portion for selectively engaging a caster wheel, a proximal end portion opposite the distal end portion, and a pivot coupling, the latter being pivotably secured to the cart or wheeled article. An actuator arm extends outwardly from a distal end portion of the torque shaft, with the actuator arm slidably engaging the proximal end portion of the brake lever. The torque shaft and the actuator arm are rotatable together to urge the brake lever toward the braking or non-braking position

An electric actuator having a hand-screw release device, including: housing, drive motor, transmission assembly, rotary screw rod and driving nut, and further including: clutch device configured to engage or disengage power transmission between the transmission assembly and the rotary screw rod; a self-locking device configured to produce a friction resistance against the rotary screw rod when the rotary screw rod rotates reversely; and a hand-screw release device including a release rotary knob, the first driving member being connected to the clutch device, the second driving member being configured to connect the self-locking device, and the release rotary knob being turned to present an initial state and a completely released state, wherein in the course of switching from the initial state to the completely released state, the first driving member activates the clutch device to disengage the power connection, and the second driving member activates the release torsion spring to release.

A method of servicing a brake system, comprising: (a) moving an actuator of the brake system from a first position to a second position; (b) conducting a manual operation on the brake system when or after the actuator reaches the second position; and (c) after completing the manual operation, moving the actuator to a third position.

A braking device of at least one rotary shaft (S) extending along an axis X includes an actuation unit (I) comprising at least one winding (B), two friction discs (D1, D2), an end flange (F1), an intermediate flange mounted between the two friction discs (D1, D2), and two magnetic armatures (A1, A2) biased by two series of springs (R1, R2). The magnetic armatures (A1, A2) are arranged in series along the longitudinal axis X, with each of the series of springs (R1, R2) respectively biasing a magnetic armature (A1, A2). A series of springs (R2) passes through the thickness of one of the two magnetic armatures (A1) in order to bias the other magnetic armature (A2).

A coupling system having an inner tube, a collar, a circular gasket concentrically disposed between the inner tube and the collar; a pair of CAM levers structurally engageable with the collar, and a handle connecting the pair of CAM levers such that a user can single-handedly move the handle between the locked position and the unlocked position.

A lift vehicle comprises a base, a battery arranged within the base, a drive motor powered by the battery and configured to drive a wheel, a scissor lift including a first end coupled to the base and being movable between an extended position and a retracted position, a work platform supported by a second end of the retractable lift, and a linear actuator having a lift motor. The lift motor is powered by the battery, and the linear actuator is coupled to the retractable lift so that rotation of the rotor moves the retractable lift between the extended position and the retracted position. The lift vehicle further includes an electromagnetic brake and a centrifugal brake coupled to the lift motor.

The invention relates to an adjustment mechanism for a vehicle disk brake, which is provided with an adjustment device for compensating the operation-induced wear on the brake linings and the brake disk, wherein the adjustment device has the following components: —a drive element (25) which is rotatably arranged within the housing of the disk brake on an axis (A) parallel to the axis of rotation of the brake disk and which can be set in rotation by a brake application device; —a shaft (40) which is arranged centrally on the axis (A), on which the drive element (25) is rotatably mounted; —a cardanic rotary bearing (45) which supports the shaft (40) in an opening (1A) of the housing in a pendulum-like manner and which is made at least partially of a deformable rubber or elastomer ring (46) and a steel ring (47) which is attached therein. In order to further develop the mentioned adjustment mechanism so that it can be produced more economically and requires only a small number of components, the steel ring (47) is supported in a sliding manner against a cylindrical bearing section (50) of the shaft (40), and a coupling consisting of a first coupling part (51), which is rotationally fixed to the shaft (40), and a second coupling part (52), which is rotationally fixed to the steel ring (47), is arranged on the axis (A), the second coupling part being a coupling ring (52) which is rotatably mounted on the shaft (40). The invention further relates to a corresponding cardanic rotary bearing (45) and a corresponding coupling ring (52).

A spring applied, hydraulically released brake includes a housing having an open end adapted to align with a vehicle surface and an internal ring extending from an inner perimeter of the housing; a piston; a disc stack including a thicker stationary disc including a tab with a hole therethrough, the hole receiving a slotted spring pin, the slotted spring pin slidably receiving a pin spring over a portion thereof; and a spring assembly adapted to urge the piston into contact with the thicker stationary disc to establish a default position of the brake; where, in a released position of the brake, the piston is not in contact with the thicker stationary disc, and the pin spring urges the thicker stationary disc into contact with the internal ring of the housing to thereby prevent the thicker stationary disc from free floating.

A brake release device and a robot manipulator employing the same are provided. The robot manipulator includes a housing and a brake element. The housing defines an inner space and has an opening, and the inner space is in communication with a space outside the housing through the opening. The brake element is disposed within the inner space. The robot manipulator stops or is allowed to actuate according to a position of the brake element. The brake release device is connected with the brake element. The brake release device is partially located in the inner space, and the brake release device partially penetrates through the opening and is exposed from the housing. When the part of the brake release device exposed from the housing is moved by an external force so as to drive the brake element to move synchronously, the robot manipulator is allowed to actuate.
