Patent number: 7980576Abstract: A vehicular suspension arm is provided in which an arm main body (1) includes a main plate (2) press-formed as a main part of the arm main body and having a short cylindrical part (EB) provided integrally with one end by flanging, and a reinforcing plate (H) superimposed on one of upper and lower faces of the main plate (2) and reinforcing the main plate (2). The reinforcing plate (H) has an eye-shaped head part (Ha) formed in an annular shape and arranged coaxially with the short cylindrical part (EB), and a tail part (Hb) extending integrally from the eye-shaped head part (Ha) along the longitudinal direction of the main plate (2), is formed from a single plate material that is thicker than the main plate (2), and has at least the tail part (Hb) welded to the main plate (2). A bush press-fit portion (P1) is formed from an inner peripheral face of the eye-shaped head part (Ha) and an inner peripheral face of the short cylindrical part (EB).Type: GrantFiled: August 16, 2006Date of Patent: July 19, 2011Assignee: Honda Motor Co., Ltd.Inventors: Mitsuru Inoue, Fumio Kikuchi, Yutaka Hozumi, Jun Matsuike

Patent number: 7398982Abstract: A knuckle is formed by a knuckle body and a lower arm support bracket fastened to front and rear fastening portions provided in a lower portion of the knuckle body with front and rear bolts. When the knuckle bumps from a normal position, an angle of a line connecting fastening surfaces of the front and rear fastening portions moves closer to the horizontal.Type: GrantFiled: March 7, 2005Date of Patent: July 15, 2008Assignee: Honda Motor Co., Ltd.Inventor: Yutaka Hozumi

Patent number: 7354052Abstract: In manufacturing a knuckle body forged or cast from light alloy of a suspension device, a large vertical height of a pair of bosses protruding downward from front and rear ends in a lower portion of the knuckle body may cause degradation in forgeability or castability of the knuckle body to hinder manufacturing, and also cause reduction in rigidity of the bosses to reduce mounting strength of a lower arm support bracket made of ferrous metal. A vertical height of the pair of bosses of the knuckle body is set to be smaller than a vertical height of the lower arm support bracket, thereby improving forgeability or castability of the knuckle body and increasing rigidity of the bosses.Type: GrantFiled: February 28, 2005Date of Patent: April 8, 2008Assignee: Honda Motor Co., Ltd.Inventors: Yukihiro Orimoto, Yutaka Hozumi

Patent number: 7234712Abstract: In a high-mounted double wishbone suspension device, an arm portion extending upward from a knuckle main body portion, through which an axle runs, is provided with a tie rod connection portion. A tie rod for turning a wheel is connected to the tie rod connection portion. The distance between the axle and the tie rod connection portion is increased to effectively suppress knuckle lateral vibration centered on the axle by the tie rod. Therefore, it is possible to reduce road noise without increasing the number of components or the weight. In particular, since the tie rod is connected to a joint provided on a lower face of the tie rod connection portion, it is possible to minimize vertical positional change of the tie rod, while suppressing lateral vibration of the knuckle by raising the position of the tie rod connection portion, whereby the arrangement can be easily applied to a conventional vehicle merely by replacing the knuckle alone.Type: GrantFiled: December 9, 2004Date of Patent: June 26, 2007Assignee: Honda Motor Co., Ltd.Inventors: Tatsuya Yamazaki, Hirokazu Hirata, Yutaka Hozumi, Akihiro Maejima

Patent number: 6179309Abstract: In order to reduce a partially concentrated load affecting a spring seat by repulsion of the coil spring, an edge of the upper end of the coil spring is disposed against a portion of the spring seat having a relatively low solidity. Therefore, it is possible to eliminate the problem that the coils of the coil spring interfere with each other if a mid-portion of the coil spring in vertical direction is offset to the side to provide a partially concentrated load.Type: GrantFiled: January 20, 1998Date of Patent: January 30, 2001Assignee: Nissan Motor Co., Ltd.Inventors: Masaharu Satou, Yutaka Hozumi

Patent number: 6076841Abstract: In order to simplify mounting a coil spring to a vehicle body, a connecting device, which connects a spring bracket to the vehicle body, is disposed at an inner circumferential portion of the coil spring. This eliminates the problem that the spring bracket needs a space for connecting to the vehicle body about an outer circumference of itself.Type: GrantFiled: January 20, 1998Date of Patent: June 20, 2000Assignee: Nissan Motor Co., Ltd.Inventors: Masaharu Satou, Yutaka Hozumi
