Publication number: 20080135354Abstract: A brake caliper of a disc brake includes a housing with a bore, in which a piston is arranged in an axially displaceable fashion, a shaft for actuation, which is mounted in a rotatable and axially displaceable fashion, two ramp elements being rotatable in relation to each other, a readjusting device with a spindle, and an axial bearing that is active between the shaft and the spindle. A generic brake caliper of a disc brake includes components having a construction to withstand stress so that they are exposed to even, low stress without detrimental tension peaks. A toothing is provided on a circumference of the spindle, and a form-fit accommodation means for the toothing is provided. The accommodation means are unrotatably connected to the housing and secure the spindle against twisting. A calotte arrangement is also provided as an axial bearing, which comprises a calotte shell with a concavely curved surface and a calotte pivot with a convexly curved surface.Type: ApplicationFiled: November 25, 2005Publication date: June 12, 2008Inventors: Ralph Petri, Rolf Weiler, Jurgen Balz, Michael Weidenweber

Patent number: 6334514Abstract: A bicycle disc brake is provided in which a support member movably couples the brake caliper to the frame of the bicycle. The bicycle disc brake caliper has a caliper housing with a single piston unit. The piston unit is movably coupled to the housing between a release position, in which the piston unit is spaced from a disc brake mounted to a wheel of a bicycle, and a braking position, in which the piston unit engages the disc brake of the bicycle wheel. The piston unit has a first friction member movably coupled between a release position and a braking position and a second friction member arranged substantially parallel to the first friction member to form a disc brake receiving space between the first and second friction members. In one embodiment, the caliper housing is movably coupled to the support member by a pivot pin. In another embodiment, the caliper housing is movably coupled to the support member by a linkage assembly.Type: GrantFiled: February 2, 2000Date of Patent: January 1, 2002Assignee: Shimano Inc.Inventors: Kanji Kirimoto, Yoshiaki Ando, Kenji Ose, Tadashi Ichida, Toshio Tezuka, Tatsuya Matsushita

Patent number: 6223867Abstract: A disk pass portion for receiving a part of a disk is provided between a cylinder portion and an outer claw portion of a caliper body at the inner peripheral side of a bridge portion of the caliper body. A pair of mounting portions extend arcuately from both sides of the bridge portion to lie outside the disk pass portion with respect to the radial direction of the disk. A pair of sliding pins are secured to the distal ends of the mounting portions through pin bolts and slidably fitted in pin-fitting holes provided in a mounting member supporting the caliper. When the brake is activated, friction pads are pressed against the disk by the caliper. At this time, deformation of the caliper by reaction forces from the disk is small around the area where proximal portions of the mounting portions are connected to the caliper body.Type: GrantFiled: October 7, 1998Date of Patent: May 1, 2001Assignees: Tokico LTD, Nissan Motor Co., Ltd.Inventors: Kazuhiro Doi, Tadashi Tamasho, Hideaki Ishii, Takahiro Tokunaga, Joichi Yokoo, Shinji Suzuki
