Patent number: 8210328Abstract: A disc rotor includes a sliding portion, a hat portion, and a connecting unit connecting the sliding portion and the hat portion. The connecting unit includes a washer arranged between the radially inner portion of the sliding portion and the radially outer portion of the hat portion, and a connecting pin having a head portion, having a shaft portion inserted through a first through-hole formed at the sliding portion, the washer and a second through-hole formed at the hat portion in an axial direction of the rotor, and riveted at an end portion of the shaft portion so as to integrally fasten the sliding portion, the washer and the hat portion. A riveted portion of the connecting pin is formed into a taper shape, and an outer circumferential surface of the riveted portion contacts and engages a tapered surface formed at the second through-hole of the hat portion.Type: GrantFiled: October 27, 2009Date of Patent: July 3, 2012Assignees: Advics Co., Ltd., Toyota Jidosha Kabushiki KaishaInventors: Masatoshi Kano, Kunio Ishihara, Haruhisa Baba, Keisuke Seto, Hitoshi Ikeuchi, Yoichi Kato

Patent number: 7111709Abstract: A disk brake device includes a pair of brake disks and right and left pairs of pads. Each pad includes a twisting compliant section that extends along a line inclined by an angle relative to a radial direction of the corresponding brake disk. The twisting compliant section facilitates the twisting of the pad about the compliant section. The twisting compliant sections of the right inner pad and the left inner pad are inclined in opposite directions relative to the twisting compliant sections of the right outer pad and the right inner pad. The twisting compliant sections of the right inner pad and the left inner pad are inclined in substantially the same direction with one another.Type: GrantFiled: May 14, 2004Date of Patent: September 26, 2006Assignee: Advics Co., Ltd.Inventor: Haruhisa Baba

Publication number: 20030213658Abstract: In a disc brake, an anti-squeal shim plate is disposed between the backing plate of each pad and a corresponding press member which presses the pad toward a disc rotor. The press member presses the pad against the disc rotor via the anti-squeal shim plate in order to generate braking force. A plurality of dimples are provided on the anti-squeal shim plate in order to limit to a specific area a press contact area between the backing plate and the press member during braking with very small pressing force.Type: ApplicationFiled: May 13, 2003Publication date: November 20, 2003Applicant: ADVICS CO., LTD.Inventor: Haruhisa Baba

Patent number: 6186288Abstract: A disc brake which can suppress pad vibration includes an outer pad which while contacting the disc rotor is turned such that the side wall of a guide groove in a support arm on the outer peripheral side abuts with the side face of a projecting section on the outer peripheral side of the pad. A pad support is positioned between the guide groove and the projecting section. The pad support includes a supporting portion, an urging portion and a connecting portion. A projection is provided in the region a little to the bottom of the guide groove on the side face of the projecting section on the outer peripheral side.Type: GrantFiled: August 28, 1998Date of Patent: February 13, 2001Assignee: Aisin Seiki Kabushiki KaishaInventors: Haruhisa Baba, Yuichi Takeo, Makoto Ogawa

Patent number: 6161660Abstract: A disc rotor for a disc brake which is designed to make it difficult to cause brake squeal includes inner and outer discs, and first and second radially extending long holes formed in the outer and inner discs. The angular intervals between the long holes are made to differ between the outer disc and the inner disc, and two vibration modes are produced to interfere with each other during braking operation by which the occurrence of a steady-state vibration mode is restrained. In addition fins are provided between the two discs, with the fins including several fins arranged to reinforce both the inner and outer discs.Type: GrantFiled: November 5, 1998Date of Patent: December 19, 2000Assignee: Aisin Seiki Kabushiki KaishaInventors: Toshitaka Suga, Haruhisa Baba, Hideyuki Kai

Patent number: 5564532Abstract: An inner arm for receiving a brake torque applied to an inner pad when a car is running forwardly includes a reinforcing rib, in the portion thereof situated near the opposite side to the side where a torque receiving portion of the inner arm is located. The reinforcing rib projects inwardly from a mounting portion 31A of the inner arm 31A to the slightly upper portion of the torque receive portion 31A of the inner arm 31A in such a manner that the amount of projection of a portion thereof situated near the torque receive portion is greater than the amount of projection of a portion thereof situated near the mounting portion.Type: GrantFiled: March 24, 1995Date of Patent: October 15, 1996Assignee: Aisin Seiki Kabushiki KaishaInventors: Haruhisa Baba, Tomoko Takeuchi, Motohiro Okade
