| 20080264738 | Disc brake caliper - An opposed piston disc brake caliper has a caliper housing arranged for mounting brake shoes on each of opposite sides of a rotor. The rotor in use is disposed between the brake shoes with each brake shoe having a backing plate and a friction lining applied to the backing plate. The caliper housing has side walls extending generally in a plane parallel to a plane of the rotor and on opposite sides of the plane of the rotor which accommodate a piston. The caliper housing has mounting members for engagement with each of the side edges of each backing plate between the radially inner edge and the radially outer edge of the friction lining. The engagement is such as to substantially limit movement of each brake shoe other than in a direction toward or away from the rotor with at least one of the mounting members being removable from the caliper housing to facilitate removal of the brake shoe from the caliper housing. | 10-30-2008 |
| 20080277212 | Service Disc Brake for a Heavy Vehicle - A service disc brake is provided for a heavy vehicle. The brake includes a brake disc, a first brake pad and a second brake pad arranged on opposite sides of the brake disc, a first displaceable piston and a second displaceable piston which are arranged to act on the first brake pad and the second brake pad, respectively, and an actuator for braking the brake disc. The disc brake includes a third displaceable piston, the second piston and the third piston being connected to each other via a closed space containing a hydraulic fluid. The braking actuator is arranged to act on the first piston and the third piston for displacement of the first piston towards the brake disc and for displacement of the third piston so as to displace the second piston towards the brake disc by the hydraulic fluid in the closed space. | 11-13-2008 |
| 20090071767 | Disc brake caliper body and a disc brake caliper comprising such a body - A body for a disc brake caliper has a mounting side limb and a non-mounting side limb, each limb housing at least one hydraulic brake cylinder. The body has a peripheral stiffening band that extends about an outer lateral surface of at least one of the limbs. In a preferred embodiment, a peripheral stiffening band extends about an outer lateral surface of each of the limbs. The stiffening band or bands provide stiffness in the body under dynamic braking conditions with a minimum of material. A method of designing and manufacturing a body for a disc brake caliper involves analysing the stiffness of the body under dynamic rather than static braking conditions and producing a caliper body with a desired level of stiffness under dynamic conditions while reducing the amount of material used to a minimum. | 03-19-2009 |
| 20090095578 | BRAKE ASSEMBLY FOR FINAL DRIVE - A braking system for a final drive for a wheel assembly of an independently powered wheeled vehicle. The system includes a service brake having a displaceable element actuatable to retard rotation of the individual wheel assembly. A park brake is positioned closely adjacent to the service brake and is actuatable independently of the service brake to displace the displaceable element to retard rotation of the wheel. Both the service brake and park brake are accessible without disturbing an electric motor with which they are associated. | 04-16-2009 |
| 20090152056 | Disk Brake With Guard Screen - A disk brake for a vehicle having a bracket which is fixed with respect to the vehicle and on which brake linings and at least one brake caliper are mounted so as to be movable in an axial direction is disclosed. The bracket and the brake caliper engage around at least one brake disk, and the brake caliper includes a housing limb with at least one actuating device, a further housing limb with at least one housing finger, and a housing bridge. A spring arrangement which generates an elastic preload between the brake caliper and the bracket is provided in such a way that the preload is aligned substantially perpendicular to a movement direction of the brake caliper. The spring arrangement comprises a spring element and a protective panel. | 06-18-2009 |
| 20090200121 | HYDRAULIC DISC BRAKE CALIPER WITH ONE WAY PLUMBING - A hydraulic disc brake caliper housing that includes first and second side portions and first and second end portions that cooperate to define a fluid path defined therein that extends between a fluid inlet and a fluid outlet. The fluid path extends from the fluid inlet, through the second side portion, through the first end portion, through the first side portion and to the fluid outlet. | 08-13-2009 |
| 20090236187 | Disk Brake - A disk brake having a brake caliper, which engages axially in a U shape around a rotatable brake disk is provided. The disk brake includes a caliper bridge, two caliper limbs and at least one actuating device. At least one brake lining is mounted in an axially movable fashion in the brake caliper. The caliper bridge has, in the peripheral direction, at least three substantially axially extending supports, wherein two of the supports are embodied as a main support and one support is embodied as a central support. These supports connect the two caliper limbs and in the process form two windows and axially project beyond the brake disk. The central support projects both beyond the brake disk and beyond the brake lining in the axial direction. | 09-24-2009 |
| 20100051394 | Bicycle brake system for preventing a front wheel from being braked alone - In on embodiment, a brake system of bicycle including left and right brake levers, front and rear wheels, a front disc brake, and a rear disc brake having a first unit and an independent second unit, the brake system includes a hydraulic line interconnected the right brake lever and the first unit; and a Y-shaped hydraulic line having a first branch connected to the left brake lever, a second branch connected to the front disc brake, and a third branch connected to the second unit. Pressing the right brake lever will actuate the first unit via the hydraulic line to brake the rear wheel, and pressing the left brake lever will actuate the front disc brake via the first and second branches to brake the front wheel and actuate the second unit via the first and third branches to brake the rear wheel respectively. | 03-04-2010 |
| 20100096223 | OPPOSED-PISTON DISC BRAKE - An opposed-piston disc brake includes cylinder connection oil passages respectively connected to a cylinder of an inner caliper portion and a cylinder of an outer caliper portion, passage communication bores respectively formed at bridge portions to extend in an axial direction of a disc in a substantially straight manner. The cylinder connection oil passages are formed using a core at the time when a caliper body is cast. The cylinder connection oil passages extend in a radially outer direction of the disc. Ends of the cylinder connection oil passages in a longitudinal direction thereof are directly connected to the passage communication bores. In a state where the caliper body is mounted on a vehicle, a top portion of an inner wall surface of one of the passage communication bores is positioned higher than the ends of the cylinder connection oil passages. | 04-22-2010 |
| 20140251737 | DISC BRAKE - A disc brake includes a pair of end-side connector parts that connect a pair of cylinder parts across over a disc rotor, and an intermediate connector part that is installed between the end-side connector parts and that connects the pair of cylinder parts across over the disc rotor and brake pads. The brake pads are provided with protrusion segments that are formed at positions that are outer end sides in a rotor radial direction and that protrude in directions separated from middle portions of the brake pads in a rotor rotational direction, and the end-side connector parts are provided with pad engaging faces on which inner regions in the rotor radial direction of the protrusion segments are oppositely disposed and which are formed of the same member as a caliper main body. | 09-11-2014 |
