  • Publication number: 20090084639
    Abstract: A brake system for a bicycle includes a number of brake members constructed to engage one another, such as a rotor and a shoe or pad. At least one of the brake members includes fiber reinforcing members. The fiber reinforcing members are distributed throughout the brake member and communicate the braking loads across a substantial portion of the brake member. The braking member is further constructed to distribute the heat associated with a braking action in a generally uniform manner across the brake member. Preferably, the brake member is formed with carbon-type fibers suspended in a Bismaleimide type material. Such a construction provides a powerful, lightweight and robust brake system.

The brake mechanism comprises a lever actuated by a brake actuator. The lever is acting on a cross bar by means of an intermediate part. The lever and the intermediate part have a line of contact moving along a circular arc during an application stroke of the brake mechanism. The cross bar of the brake mechanism is closely guided and is only moveable in the thrust direction and in the tangential direction of the brake disc. The force amplification of the brake mechanism is adapted to the force characteristics of the brake actuator.

  • Patent number: 6932197
    Abstract: A disc brake assembly is disclosed which is attachable to the wheel supporting portion of the frame of a cycle and which allows the orientation of the planar braking surface of the brake pad assembly to be infinitely variable within a defined range The disc brake assembly consists of a disc fixedly attached to a wheel, a plurality of brake pad assemblies each having a planar braking surface facing the disc and a caliper retaining the brake pad assemblies in an operative position. When braking occurs, the caliper advances at least one of the brake pad assemblies to bring the planar braking surfaces of the brake pad assemblies into and out of contact with the disc. In addition, means is disclosed for attaching each of the brake pad assemblies to the caliper with an orientation of the planar braking surface of the brake pad assembly being infinitely variable within a defined range.

  • Patent number: 6926123
    Abstract: A brake caliper formed without machining for a spot-type disc brake, in which the brake caliper after subsequent machining forms a floating caliper, has a braking force generator (12) and an opposite-lying abutment (22). For the non-machining forming of the brake caliper (10) two mould parts (34, 36) each partially receiving the brake caliper (10) are used, in which support surfaces (Q1, Q2, Q3, Q4, Q5) and action surfaces (S1/2, S3, S4, S5) are formed on the brake caliper (10) in such a way that the brake caliper (10) for the subsequent machining is supportable by its support surfaces (Q1, Q2, Q3, Q4, Q5) in a defined manner and clampable by means of clamping forces acting upon its action surfaces (S1/2, S3, S4, S5). To keep the extent of the subsequent machining to a minimum, during the non-machining forming the abutment (22) and the support surfaces (Q1, Q2, Q3, Q4, Q5) of the brake caliper (10) are formed in one and the same mould part (34).

  • Patent number: 6907963
    Abstract: A hydraulic brake system (50) for a vehicle such as a golf car or the like uses the same brakes (52) and same brake pedal (80) for both service braking and park and hold braking. The brakes (52) are selectively engaged, locked in their engaged position, and released using an integrated control assembly including a brake pedal (80), an accelerator pedal (82), and a brake pedal locking mechanism (84). The brake pedal locking mechanism (84) is configured to automatically latch the brake pedal (80) in a locked position thereof and to automatically unlatch the brake pedal (80) from its locked position upon either subsequent movement of the brake pedal (80) into an overtravel position or subsequent actuation of the accelerator pedal (82). In addition, a hydraulic accumulator (62) stores part of the energy generated upon brake pedal depression and consequent manual actuation of a master cylinder (60) of the system to maintain the brakes (52) in their fully engaged state when the brake pedal (80) is latched.

  • Patent number: 6840352
    Abstract: A golf car having a frame supported on a plurality of wheels and a bracket member fixedly coupled to the frame. A brake pedal assembly and an accelerator pedal assembly are pivotally coupled to the bracket member such that the brake pedal and accelerator pedal are disposed in a generally suspended position behind the cowling, rather than a floor mounted position. This arrangement maximizes the ergonomic placement of the pedals, and minimizes corrosion due to exposure to moisture and chemicals and damaged caused by contact with brush and debris.

  • Publication number: 20040256182
    Abstract: A floating disk brake having a caliper designed so as to be movable more freely in the radial direction of the rotor following any run-out or thermal expansion of the rotor and movable less freely in the tangential direction of the rotor to reduce uneven wear of the pads, thereby prolonging the life of the pads and reducing the possibility of fading at minimum cost. The caliper is supported on a mount through slide guides so as to be slidable in the direction of the axis of the rotor of the brake. The slide guides each include a slide pin fixed to the caliper, and a pin hole formed in the mount to receive the slide pin. A first clearance is defined between the mount and the caliper in a direction tangential to the rotor, and a second clearance is defined between the slide pin and the pin hole of each slide guide such that the first clearance is smaller than the second clearance.

  • Publication number: 20040168868
    Abstract: A disc brake pad backplate assembly includes a backplate and a pad spring. The backplate and/or the pad spring includes a retaining feature to mount the pad spring to the backplate and circumferentially spaced abutments arranged to restrain lateral movement of the end portions of the pad spring. The pad spring is dimensioned relative to the spacing of the abutments such that a radially inward loading applied at a central portion of the pad spring causes the pad spring to function in a first resilient leaf spring-like mode in which the pad spring end portions are unrestrained up to a predetermined load limit. Above the predetermined load limit, the end portions are restrained by the abutments such that the pad spring functions in a second buckling mode. The spring rate is relatively low in the first mode and relatively high in the second mode.
