    Abstract: A heavy-duty vehicle brake assembly with a sealing interface includes a brake shoe, which includes a shoe table mounted on a web and a brake lining mounted on the shoe table. The shoe table is coated with a zinc-rich coating to form the sealing interface between the brake lining and the shoe table. The sealing interface resists the formation of corrosion cells on the brake shoe table, which in turn reduces the build-up of significant rust between the brake shoe table and the brake shoe lining, thereby preventing cracking and potential dislodging of the lining, while also facilitating replacement of linings when they eventually wear. A method of constructing a heavy-duty vehicle brake assembly with a sealing interface is also provided.

At least the brake pad on the application side is mounted movably in the direction of the brake disc in a pad shaft of the brake carrier. A device for the visual identification of the wear of a brake pad and/or brake disc is constructed so that for identifying wear, a pointer element, extending in the opposite direction to the brake disc, is connected at least at one screw.

  • Patent number: 8746418
    Abstract: Disclosed is a disc brake. The disc brake includes clip parts provided at inner portions of both side ends of a pair of pad plates and engaged with protrusions formed in the carrier and torsion pins fitted into the clip parts such that the clip parts are rotated between the pad plates upon a braking operation of the disc brake. Upon the braking operation, the pad plates push the carrier so that the clip parts are rotated about the torsion pins by the pad plates. Thus, strain energy of the carrier is absorbed through warpage deformation of the torsion pins, so that the carrier has sufficient strength even if an outer beam is removed.

  • Patent number: 8561763
    Abstract: A brake device includes a pad 100a having a friction surface 101 and a disk 200a having a friction surface 201 sliding on the friction surface 101. The friction surface 101 includes hard particles 102 that are elastically supported in a y direction perpendicular to the friction surface 201. The friction surface 201 includes a plurality of convex portions 202 that is disposed in a direction where the friction surface 201 slides on the friction surface 101. When the friction surface 201 slides on the friction surface 101, the hard particles 102 continuously come into contact with the convex portions 202, respectively, while being displaced in the y direction perpendicular to the friction surface 201. Accordingly, the brake device can improve abrasion resistance as compared to a brake device that mainly performs abrasive friction.
