A disc brake which is particularly designed for arcuate travel of less than 360 degrees has pie shaped segments, i.e. segments which are not complete circles which are interleaved. Some segments are rotatable about an axis and others are stationary and have friction brake material carried on them at a position remote from the axis of rotation.

A disc brake having a brake carrier (10) which may be fastened to the vehicle and to which bolts are fastened, comprises brake pads (32a, 32b), in the supporting plates of which U-shaped recesses (40, 40') are formed, which are placed onto the bolts, such that the brake pads are axially movably guided relative to the brake disc.

A brake is disclosed for use with a cart. The brake includes a pad that contacts the floor to resist movement of the cart. The height of the pad is adjustable.

A brake mechanism includes an input, a chassis, a lock and a release mechanism. The input is an axially extending input having first and second ends. The chassis interfaces with the input such that the input is movable relative to the chassis. The lock is coupled to the chassis for constraining movement of the input relative to the lock. The release mechanism is coupled to the lock and is responsive to a force applied relative to the input and the chassis such that when the force is greater than...

An electronically controlled disc brake with self-servo effect comprises a ramp plate provided with a brake pad for engagement with a brake disc, an actuator for applying a control force on the ramp plate substantially transverse to the brake disc, a ramp bridge, and rollers movable in ramps in surfaces facing each other of the ramp plate and the ramp bridge. The arrangement of these members is such that a movement of the ramp plate in the tangential direction of the brake disc will cause it to ...

A brake disk has a disk body. The disk body has two sides, an outer periphery, a central hole, multiple through holes and multiple curved grooves. The central hole is defined through the disk body. The through holes are defined through the disk body around the central hole. The curved grooves are defined respectively in the sides of the disk body and each groove has a first end extending to the outer periphery of the disk body and a second end extending to and communicating with one of the throu...

An improved brake actuator is disclosed that automatically adjusts for brake pad wear, thereby retaining a given retraction space from a fully actuated position. The actuator is hydraulically actuated and the components for positive retraction are housed within the hydraulic actuator, thereby protecting the components from the elements. The brake actuator has particular application for a ring brake having opposed cylindrical braking surfaces. An improved self-locking brake pad is also disclosed.

The invention relates to a brake cylinder (100) and a hydraulic rim brake comprising a unit for receiving a brake pad (103). With known brake cylinders, it is difficult to remove the running wheel if the tire mounted on the wheel rim (6) is substantially wider than the wheel rim (6), since the wheel has to be moved through the gap between the two brake pads arranged on the brake cylinder. The brake cylinder according to the invention should have a simple structure and permit easy removal of the ...

A hand brake for manually actuating brake cylinders, particularly for an air braking system on railway vehicles, has a piston tube extending from the piston of a brake cylinder and an actuating rod connected to the brake linkage positioned within the piston tube. A device for adjusting the actuating rod with respect to the piston tube device comprises a thrust ring acting upon a portion of the piston tube. A brake ring is positioned around the piston tube and is rotatable by a manually actuated ...

When it is in a forward or backward range, in an idle state, the vehicle is perfectly stationary, brake releasing velocity Bv is larger than Bv_on, brake stroke Bs is smaller than Bs_on and braking force Bf is larger than driving force Fd, a brake ECU executes a program that includes the steps of starting a timer, controlling the braking force Bf such that it becomes approximately equal to the driving force Fd, and controlling the braking force Bf such that it gradually decreases until it attain...
