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

Patent number: 6182801Abstract: In the pushing anchor type disc brake device, reduction of noise and prevention of uneven wear can be accomplished especially in the brake device in which brake torque of the outer pad is transmitted via the caliper. In the disc brake device, the caliper is guided by a pair of guide pins composed of a main pin and a sub-pin. In order to transmit the brake torque of the outer pad via the caliper and the main pin, the back plate of the outer pad and the caliper are engaged with each other by engaging a protrusion with a recess, wherein the engagement is conducted at a plurality of portions in the circumferential direction of the rotor, so that the brake torque can be transmitted from the outer pad to the caliper. The main pin is arranged on the rotor run-out side, so that a pushing anchor structure can be formed. A pair of guide pins and guide holes of the support member which engage with the pair of guide pins stride the rotor and extend exceeding a facing section where the rotor faces the outer pad.Type: GrantFiled: June 1, 1998Date of Patent: February 6, 2001Assignee: Akebono Brake Industry Co., Ltd.Inventors: Hirokazu Yoshida, Kazuyuki Shibayama, Seiya Odaka
