Publication number: 20110233886Abstract: In a vehicle steering device, extendable portions whose elastic properties corresponding to a force acting in a compressing direction and whose elastic properties corresponding to a force acting in a stretching direction are asymmetrical are disposed in a symmetric fashion at intermediate sections of tie rods. Thus, an effective steering gear ratio with respect to leftward and rightward steering can be properly changed in accordance with a vehicle speed by using a simple configuration that does not use a complex mechanism having a motor. In this case, a steering gear ratio can be mainly changed for one of the wheels, while a linear lateral force corresponding to steering can be generated at the other wheel. Moreover, since the steering gear ratio can be changed mechanically without performing motor control, the occurrence of control delay can be prevented, thereby reliably preventing deterioration of the driver's operational feel.Type: ApplicationFiled: March 21, 2011Publication date: September 29, 2011Applicant: FUJI JUKOGYO KABUSHIKI KAISHAInventor: Yuichiro Tsukasaki

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

The solid rod extends into the tubular rod. An adjustment nut attached to the tubular rod threadingly receives the solid rod and rotation of the adjustment nut adjusts the length of the torque rod assembly. The length adjustment system can be incorporated into a straight torque rod assembly or into a V-configuration torque rod assembly.Type: GrantFiled: September 10, 2004Date of Patent: January 16, 2007Assignee: The Pullman CompanyInventor: Ronald J McLaughlin

Patent number: 7159903Abstract: A steering mechanism is mainly comprised of an upper and a lower axle seat, in which the upper axle seat and the lower axle seat are provided for receiving an upper axle and a lower axle respectively. The upper and the lower seats are combined together by pivotally jointing each other with a respective inverted U-shaped and a U-shaped pivot-joint ends, where a universal joint having two ends thereof coupled with the upper and the lower axles is arranged in a space enclosed by the pivot-joint ends, so that a diversion may be made by taking the upper axle as a rotation center irrespective of the forward rake or backward rake of the upper axle seat.Type: GrantFiled: April 27, 2004Date of Patent: January 9, 2007Assignees: Chen-Chang Huang, Taiwan An I Co., Ltd.Inventor: Shun-Tai Huang

Patent number: 7090232Abstract: A steering knuckle assembly for vehicles includes a connector for connecting a tie rod to a knuckle body via a ball joint is freely attached to and detached from the knuckle body. In the case of changing a ball joint point at a terminal end of the tie rod, only the connector is separately developed and then mounted on the knuckle instead of developing a new knuckle structure, thereby reducing fabrication cost as well as improving workability.Type: GrantFiled: November 25, 2003Date of Patent: August 15, 2006Assignee: Hyundai Mobis Co., Ltd.Inventor: Geun-Bae Kim

Patent number: 7073822Abstract: A steering suspension system utilizing a flexible push/pull cable attached from an operator input mechanism across a suspension system to a wheel steering mechanism. An operator input mechanism is located within a land vehicle structure supported by a wheel. A suspension system connects the wheel to the land vehicle structure and a wheel steering mechanism is used to connect the wheel to the suspension system. The flexible cable connection minimizes the complexity in number of parts for the steering system while providing a flexible connection to the wheel steering mechanism allowing free suspension movement with minimal or negligible affects provided from the steering linkage.Type: GrantFiled: June 3, 2003Date of Patent: July 11, 2006Inventors: David A. Renfroe, Joe Partain

Patent number: 7073802Abstract: The present invention is particularly useful for lowering the front end of an automobile. The devices, methods, and systems of the present invention can find use in any variety of automobiles, such as trucks, sport utility vehicles (SUVs), passenger cars, and the like. The invention can be employed regardless of the type of suspension system in the automobile, and allows the vehicle to be lowered while retaining a maximum amount of travel. This is accomplished with a drop spindle having certain features such as a tap opening and a countersunk opening on the underside of the lower ball joint boss.Type: GrantFiled: May 12, 2005Date of Patent: July 11, 2006Assignee: Mike McGaughy's Classic Chevy Parts, Inc.Inventor: Mike McGaughy

Patent number: 7017926Abstract: A front-wheel suspension system comprises a steering gear frame, a control arm mounting connector, a lower control arm, a wheel carrier, and a damping device. The steering gear frame includes a front fixing plate and a rear fixing plate integrally formed on a front side and a rear side of a power cylinder and is coupled to a vehicle body. The control arm mounting connector is fixed in a longitudinal direction under the fixing plate. The lower control arm is provided with a vehicle body side connecting member coupled to both ends of the control arm mounting connector. The wheel carrier couples to a wheel side end portion of the lower control arm, rotatably supports a wheel, and is connected to a tie rod extended from the power cylinder. A damping device absorbs vertical vibration of the wheel.Type: GrantFiled: May 28, 2003Date of Patent: March 28, 2006Assignee: Hyundai Motor CompanyInventor: Unkoo Lee

Patent number: 7004485Abstract: A vehicle steering linkage member (40) comprises a socket (42), and a stud (10) having a ball end portion (48) received in the socket and supported for pivotal movement relative to the socket. The stud (10) has a longitudinal axis (52), with a shank portion (50) projecting from the socket (42) and centered on the axis. The shank portion (50) of the ball stud (10) includes a predetermined weakened portion (70). The predetermined weakened portion (70) buckles under a predetermined amount of force. The predetermined weakened portion (70) may have a cross-sectional configuration not centered on the axis (52).Type: GrantFiled: March 7, 2002Date of Patent: February 28, 2006Assignee: Koyo Steering Systems of North America, Inc.Inventors: Steven P. Spagnuolo, Glenn G. Nief

Patent number: 7000931Abstract: Methods and apparatus related to the suspension and steering of all terrain vehicles (ATVs) are disclosed. An ATV having a frame and a wheel carrier for rotatably supporting a wheel is provided. A tie rod is coupled to the wheel carrier at an outer joint. An inner joint of the tie rod is preferably located in a desirable location. A method for identifying the desirable location may include the steps of defining a first reference plane associated with a full compression position of the suspension, defining a second reference plane associated with a full extension position of the suspension, identifying a reference line formed by an intersection of the first reference plane and the second reference plane, and selecting a location proximate the reference line as the desirable location for the inner joint.Type: GrantFiled: July 19, 2004Date of Patent: February 21, 2006Assignee: Polaris Industries Inc.Inventor: Mark Chevalier
