Patent number: 7845662Abstract: A front cross member 202 of a rear subframe 53 has a recessed portion 221 which is recessed continuously over a longitudinal direction thereof. The recessed portion 221 is formed at a lower portion of the cross member 202 and is recessed upwardly, and an elastic bush 240 is fitted in a resulting recess. The elastic bush 240 has an elastic element 243 which connects together an inner tube 241 and an outer tube 242 which surrounds the inner tube 231 and is mounted on the rear subframe 53 at the recessed portion 221 as a bracket. The bracket 221 has bracket plate portions 263a, 263b which each have a plane which is brought into contact with an end face of the inner tube and folded-back portions 235, 235. The bracket 221 is disposed in such a manner as to hold therein both ends of the inner tube 241 and is configured such that the elastic bush 240 is mounted thereon by passing a bolt 224 through the inner tube 241.Type: GrantFiled: June 25, 2009Date of Patent: December 7, 2010Assignee: Honda Motor Co., Ltd.Inventors: Tsutomu Ogawa, Haruyuki Iwasaki, Izuru Hori, Yuichi Nagai, Hiroshi Akiyama, Kunihiko Kimura

Patent number: 7118601Abstract: There are provided an artificial joint device that can realize an artificial limb enabling twisting motion without a drive source, and when with the drive source, reduce the size and costs of the device, and a parallel linkage that can realize the device. The linkage connects a foot portion and a mounting plate spaced from each other. A fixed link has one end fixed to the plate, and the other end connected to the foot portion via a ball joint, making the angle of the fixed link relative to the foot portion changeable in any direction. Expansible links extend between the foot portion and the plate in an expansible/contractible manner and each have opposite ends connected to the plate and the foot portion via respective upper and lower ball joints, making respective angles thereof relative to the foot portion and the plate changeable in any direction.Type: GrantFiled: February 28, 2003Date of Patent: October 10, 2006Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Yuji Yasui, Hiroshi Kiyomoto, Isao Usukura, Youichi Nakahara, Haruyuki Iwasaki, Shungo Umeda, Kazunori Yamamoto, Masamitsu Shiono, Kazuo Okada, Manabu Nakayama, Atsushi Kubo

Patent number: 6979023Abstract: A pound or number sign shaped (#-shaped) die cast sub-frame includes first and second horizontal members and first and second vertical members. The sub-frame has four arm mounting portions provided at four corners thereof, respectively. The arm mounting portion is a die cast part obtained near a communication portion of a runner formed in a die casting machine. Generally triangular bulged portions are formed at junction portions where the first horizontal member meets the first and second vertical members. Each junction portion has increased width. The junction portion is a die cast obtained within a cavity of increased width of the die casting machine. The bulged portion is pierced to provide a hole. The bulged portion having the hole formed therein is to be mounted to a small vehicle component.Type: GrantFiled: October 31, 2001Date of Patent: December 27, 2005Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Tetsuo Mikasa, Tsutomu Ogawa, Nobuo Kubo, Fumiaki Fukuchi, Haruyuki Iwasaki

Patent number: 6612593Abstract: A suspension structure includes a subframe and a suspension arm. The suspension structure has strength lower than that of the subframe. When an excessive external force acts from a road surface on a wheel, the suspension arm is deformed before the subframe is, thereby preventing the excessive external force from directly acting on the subframe.Type: GrantFiled: November 1, 2001Date of Patent: September 2, 2003Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Tetsuo Mikasa, Tsutomu Ogawa, Nobuo Kubo, Fumiaki Fukuchi, Haruyuki Iwasaki
