A bicycle disc brake caliper assembly is basically provided with a main caliper body, at least one brake pad and a mounting adapter. The main caliper body includes a first coupling portion that is configured not to be directly attached to a bicycle frame. The at least one brake pad is movably attached to the main caliper body. The mounting adapter includes a second coupling portion that is configured to be detachably coupled to the first coupling portion, and a mounting portion that is configured to be mounted to a bicycle frame.

A brake system that includes a brake piston, a rotary to linear stage mechanism, and a clutch. The brake piston extends along a longitudinal axis. The brake piston includes a piston pocket. The rotary to linear stage mechanism includes a spindle and a nut. The nut is received in the piston pocket. The brake system is operable in a first braking application and in a second braking application. During the first braking application, the clutch is adapted to provide for the nut to rotate about the longitudinal axis. During the second braking application, the clutch is adapted to restrict or prevent the nut from rotating about the longitudinal axis.

A brake used by a mine hoist, a car, a high-speed train, etc. Gas springs are used to replace belleville springs, and a positive pressure is also always applied to brake pads to both ensure and increase the brake reliability and a positive pressure per unit area. The brake resolves problems such as deformation of the belleville springs, a serious change in an elastic force, sudden cracking and decompression, inconvenient monitoring, and a manufacturing difficulty. A brake head floating structure is used to reduce a requirement on end face runout of a brake disc. An oil-gas linkage plunger pump is used to replace a hydraulic station, which greatly reduces manufacturing costs, and reduces energy consumption.

An apparatus (10) that houses functional components of a mechanical assembly includes a frame component (12) formed of a first material, the frame component (12) bearing primary load, torque or pressure applied to the apparatus (10) during operation of said mechanical assembly. The housing apparatus (10) further includes a composite reinforcement component (130) for resisting forces applied to the apparatus during operation of the mechanical assembly and an enclosure component (80) formed of a second material of lower density than the first material of the frame component (12), the enclosure component (80) covering and sealing at least the functional components of the mechanical assembly from external conditions during operation of the mechanical assembly.

A piston manufacturing device includes a first forming device (42) configured to form an annular groove (61) in a piston (11), and a second forming device (52) configured to press an edge (15) of an opening (14) of the piston (11) toward other end side in an axial direction of the piston (11) and to form a thick section (65) extruded from an inner circumferential surface (12b) arranged between the edge (15) and the groove (61) toward an axial center side of the piston (11), wherein a recessed section (53) is formed at a portion of the second forming device (52) that is arranged to abut the edge (15) so that an inner circumferential side of the edge (15) is plastically deformed toward the other end side in an axial direction of the piston (11).

The present disclosure relates to an electronic brake system. The electronic brake system includes a reservoir in which a pressurized medium is stored, an integrated master cylinder having a master chamber and a simulation chamber, a reservoir flow path provided to communicate the integrated master cylinder with the reservoir, a hydraulic pressure supply device provided to generate a hydraulic pressure by operating a hydraulic piston according to an electrical signal output in response to a displacement of the brake pedal, a hydraulic control unit including a first hydraulic circuit provided to control the hydraulic pressure to be transferred to two wheel cylinders, and a second hydraulic circuit provided to control the hydraulic pressure to be transferred to the other two wheel cylinders, and an electronic control unit configured to control valves based on hydraulic pressure information and displacement information of the brake pedal.

A brake cylinder for an air-operated brake, in particular for commercial vehicles, has a housing including a front cover (11), wherein the front cover (11) is provided with a cylindrical lateral surface (16) and with a base wall (18) adjoining the lateral surface (16). The base wall (18) is provided with an elevated portion (19) having a central bore or middle opening (23) for a cylinder plunger. The front cover (11) is provided with a rib (46). The rib (46) extends on the base wall (18) in addition to the elevated portion (19).

A field-replaceable sleeve assembly for a yaw brake assembly of a wind turbine includes a sleeve body and a sleeve attachment portion. The sleeve body is configured to be installed from a top side of a turbine bedplate into a receiving portion of the turbine bedplate of the wind turbine and secured to the turbine bedplate by activation of the sleeve attachment portion from the top side of the turbine bedplate.

A hydraulic motor brake for providing load holding torque to a hydraulic motor and comprising a housing, a plate fixedly mounted within the housing, a piston mounted for bi-directional translation relative to the plate along a longitudinal axis, and a plurality of friction-producing members arranged such that the piston and plate at least partially define a brake release chamber and the piston, normally biased in engagement with the friction-producing members to produce load holding torque, translates away from the plate and disengages from the friction-producing members to stop producing load holding torque in response to pressurized hydraulic fluid being received by the brake release chamber. The hydraulic motor brake further comprises a wear plate with the brake housing and wear plate defining bores arranged in coaxial alignment with threaded bores of the hydraulic motor for detachably attaching the hydraulic motor brake to the hydraulic motor as a self-contained unit.
