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 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.

There is provided a brake assembly structure for a transmission. An automatic transmission includes a torque converter, a transmission case, and a two-way clutch and a first brake which are accommodated in the transmission case and adjacent to each other. The first brake includes a drum, an outer plate that is fixed to the drum in such a manner that the outer plate is unrotatable with respect to the drum, an inner disk that comes in contact with the outer plate in an axial direction, and a hub to which the inner disk is fixed in such a manner that relative rotation is not permitted. The drum is provided separately from the transmission case and includes a hydraulic chamber. The two-way clutch is assembled in the transmission case and the first brake is then assembled in the transmission case.

Provided is a non-excitation operable electromagnetic brake that includes a manually operable rotary cam for switching over a rotor to a brake releasing state, but that allows easy recognition of switchover to the brake released state via an operation reaction force and that also allows reliable keeping of the rotary cam under its acting state. Even when an electromagnet is under a non-excited state, when a rotary cam is rotatably operated to an acting position, an acting portion of the rotary cam slidably operates a rotor via a releasing plate to a brake releasing state against springs. The acting portion of the rotary cam is formed linear along a tangent at a center of the acting portion with respect to a rotary cam rotational direction.

A stroller capable of making braking easy and maintaining itself in a brake release state with a simple structure is provided. The stroller includes a body frame, wheels, a brake member located at a lower end of a leg section, and displaced between a braking position and a brake release position, an operating mechanism attached to the push rod, operatively associated with the brake member through a coupling member coupling the operating mechanism and the brake member, and being capable of being displaced between a first position corresponding to the braking position of the brake member and a second position corresponding to the brake release position of the brake member, a bias member biasing the brake member to move the brake member to the braking position, and a maintaining mechanism maintaining the operating mechanism in the second position corresponding to the brake release position.

A safety device designed to lock an engine flywheel and shaft in place during maintenance and repairs on the engine.
