Abstract:
In the disk brake of the present invention, each arm of the carrier has a projecting pad guide, and each friction pad has recesses fitted onto the pad guides of the carrier. Each pad spring has integrally formed therewith a generally U-shaped guide plate which is bent along the pad guide and resiliently engaged with and presses against the pad guide to thereby mount the pad spring on the arm of the carrier. Each recess of the friction pads includes a groove at a position corresponding to at least one bent portion of the guide plate, which is separated from a corner portion of the pad guide and deformed into a projection toward the recess.
Abstract:
A brake for a hoist gear is provided with a pair of brake shoes for braking a disk to be braked arranged on a winding drum side by pressing both sides of the disk. Floating pin fitting piece portions protrude integrally from a body of a bearing supporting the winding drum. A caliper is attached to the fitting piece portions through floating pins. Axis points of the floating pins are arranged in point symmetry of approximately 180.degree. in respect of an axis point of a push rod inserted into the caliper in order to uniformly contact the disk face.
Abstract:
A floating caliper-disc type brake is capable of defining a second gap between a disc and an outer pad when the same brake is released, preventing a dragging torque from being generated during the traveling of a vehicle, improving fuel consumption of the vehicle, and solving a jar generated when the outer pad is slid with respect to the disc. The floating caliper-disc type brake comprises an elastic member interposed between a support and a caliper and being gradually varied in retaining position thereof with respect the support and caliper depending on wearing amount of the outer pad, wherein when the brake is applied, the caliper is moved in the other direction while elastically deforming the elastic member within deformable amount of said elastic member, and when the brake is released, the caliper is moved in one direction by a second length which is smaller than a first length owing to elastic deformation of the elastic member so as to define a first gap between the disc and an inner pad and a second gap between the disc and the outer pad.
Abstract:
A steering knuckle assembly for the drive wheels of automotive vehicles including a carrier component adapted to be secured to the wheel suspension and carrying a floating-caliper brake and a wheel axle bearing, and a rotatably mounted wheel axle having a constant-velocity joint for the drive and a flange for the attachment of a brake disc. According to the present invention, the carrier component with the disc brake and the wheel axle bearing together with the wheel axle, the flange, the brake disc and a bowl shaped part of the constant-velocity joint are coupled to form a module which can be secured to the wheel suspension as a preassembled unit in the final assembly of the automotive vehicle. The carrier component is preferably formed integrally with supporting arms for the disc brake, fastening sections for the wheel suspension and a lever for the steering, on the one hand, and a radially internal ring of the wheel axle bearing, a shell-shaped part of the constant-velocity joint and the flange for attaching the brake disc are formed integrally with the wheel axle, on the other hand.
Abstract:
A modular pin mounted caliper assembly is provided for use in a disc brake. The modular caliper assembly can be angled with one or more other modular caliper assemblies. Each caliper segment has a housing with a piston disposed in an inboard portion thereof for movement in an axial direction. A pair of flanges extend from opposite sides of the housing and are axially offset from each other enabling the connection and alignment of a plurality of segments. The resulting caliper can be used in a wide variety of vehicles despite changes in brake torque requirements. The modular caliper assembly includes a plurality of inboard and outboard brake shoe pairs. Each brake shoe has a pair of pin engaging features extending from opposite outboard ends of the brake shoe. Like the caliper segment flanges, the pin engaging features are axially offset from one another, enabling the shoes to be overlapped on common pins.
Abstract:
A heavy duty brake assembly including a caliper mounted on a housing in a position to bridge a brake disc, a pair of screws mounted on the housing, a bushing and a washer mounted on each of the screws, a notch formed in the periphery of each of the bushings intermediate the ends thereof, a self-adjusting repeatable retraction device mounted on each of the bushings for supporting the caliper, the device including a plastic sleeve mounted on each of the bushings, a pair of tabs formed in each of the sleeves and aligned with the notches to limit the paths of travel of the sleeve with respect to the bushings, a bell spring formed on one end of each of the sleeves for biasing the caliper to a neutral position with respect to the disc and a seal formed on each end of the plastic sleeve to seal the sleeve to the bushing.
Abstract:
The invention is related to a spot-type disc brake with a stationary brake carrier (19) at which a floating caliper (1) is slidingly guided which straddles the edge of a brake disc (10), with two brake cylinders (11, 12) which are positioned on the internal axial side of the brake disc (10) aside each other and whose brake pistons (13, 14) act on the brake shoes (5, 7) which are arranged on the same axial side and in circumferential direction of the brake disc (10) at a distance from each other. According to the invention a third brake shoe (6) is fixed on the external axial side of the brake disc (10) to the floating caliper (1), which brake shoe is positioned staggered in such a manner that its friction area point of gravity (36) comes to be arranged substantially between the other two brake shoes (5, 7) in the circumferential direction of the brake disc (10). Braking noises and brake rubbing are eliminated by this arrangement. Further advantages of the inventive brake are constituted by its ease of serviceability in view of an ease of mounting of the brake shoes (5, 6, 7) and by its floating caliper (1) which allows to be manufactured with ease and at but low cost and with but little material, and which simultaneously with a low weight affords an elevated stiffness and a large brake disc diameter.
Abstract:
A pneumatically operated sliding-caliper disk brake wherein the sliding-caliper is mounted to two fixed guide members by two guide bearings having elastomer bearing bushings of different length bearing surfaces for displacement in the axial direction of the brake disk. The longer elastomer bearing bushing is dimensioned such that a transition fit exists to the its guide member, while the shorter elastomer guide bushing is dimensioned to have a defined play to its guide member.
Abstract:
A floating-caliper spot-type disc brake is disclosed having an arrangement for actively retracting the indirectly actuated external brake shoe to create a clearance with the brake disc. Elastic spring elements (24, 34, 38, 45) engage the external brake shoe (10) and the carrier arms (2, 3) of the brake carrier (1) and which are elastically tensioned by actuation of the brake to allow a slight retraction of the external brake shoe when the elements relax as the brake is released. The spring elements are mounted to allow a frictional grip to be overcome to shift the relative relaxed position of the spring element and external brake shoe as the brake lining wears, so that a constant disc clearance is maintained.
Abstract:
A spot-type disc brake, in particular to a disc brake straddling the brake disc internally in which a brake and essential assemblies required for that brake and a process for mounting of such a brake are provided. Particular mounting arrangements allow each of the brake shoes to be removed in a radial direction without having to disassemble the housing or parts of the housing.
