  • Patent number: 8936136
    Abstract: A brake system comprising a brake disc that rotates about a center axis, a brake mount, a brake caliper attached to the brake mount and including a brake pad, and an adjuster between the brake mount and the brake caliper. The adjuster can move the brake pad toward and/or away from the brake disc. In one embodiment, the brake caliper is attached to the brake mount by a post extending through an elongated opening in the brake caliper and nonparallel to the center axis. The adjuster can change a relative location of the post within the elongated opening. The adjuster can include an end that extends into the elongated opening and works against the post. The post can include a fastener threaded to the brake mount in a direction substantially perpendicular to the center axis, and the fastener can extend through an elongated opening in the brake caliper.

  • Patent number: 8936138
    Abstract: A disc brake includes a brake disc, a sliding caliper, a single piston, and a brake pad carrier comprising a leading part and a trailing part. The brake pad carrier includes mounting features for securing the brake pad carrier to an associated structure of a vehicle. The mounting features define a mounting side and a non-mounting side of the brake. A mounting side brake pad comprises mounting side friction material and a non-mounting side brake pad comprising non-mounting side friction material. The center of pressure of the non-mounting side friction material is circumferentially aligned with the piston and the center of pressure of the mounting side friction material is offset in relation to the piston towards the leading part of the brake pad carrier.

A base plate holds the member on a front surface and a guide plate is at the center of a back surface of the base plate and accommodated in a concave portion of the caliper arm. A base plate front surface is in parallel to a frictional surface of the member. A thickness of the base plate is larger on an inner circumferential side than an outer circumferential side. A thickness of the guide plate is smaller than a depth of the concave portion of the caliper arm. In a state where the frictional surface of the member faces the frictional surface of the disc in parallel, the guide plate is fitted, with play, into the concave portion of the caliper arm.

  • Patent number: 8919503
    Abstract: A brake lining for a railroad car brake includes friction members which are pressed onto the sliding surface of a brake disc, and a back plate which is attached to a brake caliper in order to support the friction members. The friction members are dividedly arranged in a radial direction and in a circumferential direction of the brake disc. A disc spring is disposed between each respective friction member and the back plate. An outer peripheral surface of the friction members facing the back plate is formed in a convex curved shape in an area outside the elastic member. When a light pressing force is applied, a pressing force is transmitted from the back plate to the friction members via the disc springs. When a heavy pressing force is applied, the back plate and a rounded surface portion make contact, thereby directly transmitting a pressing force to the friction members.

A caliper is retained on the anchor by a pin to align first and second friction members with a rotor. Pressurized fluid that acts on a piston moves the first friction member into engagement with the rotor creates an axial force that axially slides the caliper on the pin and moves the second friction member into engagement with the rotor to create a clamping force that urges the friction members into engagement with the rotor. The clamping force rotates the caliper on the pin and brings the first friction member into engagement with the first cantilever beam and the second friction member into engagement with the third cantilever beam to oppose the rotation of the caliper during a brake application.

  • Patent number: 8573371
    Abstract: A cast iron brake caliper with improved fatigue life, and a process and process equipment for pre-stressing a cast iron brake caliper to provide improved fatigue life, is provided. In the process, a load is applied to a cast iron caliper, where the load is high enough to locally yield and plastically deform the cast iron material, but not high enough to cause material failure, such as cracking. Upon load removal, residual compressive stresses in the cast iron caliper lower the mid-point of the stress range the plastically-deformed region of the caliper sees during in-service use, and thereby lowers the peak stress seen in this region, increasing fatigue life. The process permits a cast iron brake caliper to be designed to use less material and thus fit within constrained wheel rim envelopes, without the need to resort to high cost materials or other alternative design strategies.

    Abstract: A brake assembly includes a brake pad, a bracket supporting the brake pad and having a first portion, a second portion spaced apart from the first portion, and a linkage interconnecting the first and second portions. The linkage is configured to transfer tensile loads between the first and second portion, but is characterized by the absence of any bending modes. The absence of bending modes prevents excitation of the linkage, thereby reducing sound generated during application of the brake assembly.

  • Patent number: 8540061
    Abstract: A system and method are provided for mounting, removing and retaining brake pads in disc brakes, such as air-operated disc brakes utilized on commercial vehicles, in a manner which does not require the use of separate brake pad retaining devices while providing positive retention of the brake pad. A preferred embodiment includes a brake caliper mount having brake pad abutment surfaces having radially-oriented and lateral grooves which permit a brake pad with corresponding projections on is lateral sides to be inserted through an opening of the brake caliper into the radially-oriented grooves until the backing plate projections are aligned with the lateral groove, and advancing the brake actuator behind the brake pad to place the brake pad in an operating position in which the actuator prevents the brake pad from realigning with the radially-oriented grooves until the actuator is retracted to permit brake pad extraction.

  • Patent number: 8528707
    Abstract: Disclosed is a disc brake for a vehicle, such as an electronic wedge brake, capable of preventing a disc from being subject to the moment due to misalignment of inner and outer friction members with respect to a disc. The disc brake includes a disc rotating together with a vehicle wheel, inner and outer friction pads disposed at both sides of the disc, respectively, a wedge unit installed at rear sides of the inner and outer friction pads to press the inner and outer friction pads against the disc, a driving device that operates the wedge unit for a braking operation, and a sync member for synchronizing braking positions of the inner and outer friction pads with respect to the disc. Since the disc is prevented from being subject to the moment, uneven wear does not occur in the friction member and/or the disc and deformation of the disc is prevented.

  • Patent number: 8453804
    Abstract: There is disclosed a disc brake system incorporating a split caliper having a first caliper half integrally formed with a mounting plate for mounting the caliper on a vehicle. A second caliper half is fixedly and removably attached to the first caliper half in spaced apart relation to provide room for a rotor to be disposed between the caliper halves. The joiner plates permit adjustment of the distance between the caliper halves to accommodate rotors of different thickness. The split design provides a slimmer caliper profile permitting the use of larger diameter rotors in the same space. A splined rotor carrier permits mounting of the rotor on to a wheel hub housing having a corresponding spline. The disc brake system of the present invention is particularly useful in retrofitting existing vehicles, especially light armored vehicles (LAV's).
