  • Publication number: 20070262550
    Abstract: A vehicle suspension utilizes a shunt linkage assembly between first and second torsion springs to change effective lengths of the first and second torsions springs in jounce and roll modes of operation. A first lever arm couples the first torsion spring to a first wheel and a second lever arm couples the second torsion spring to a second wheel component. The shunt linkage assembly acts as a tension-compression link between the opposed first and second lever arms. During jounce the first and second torsion springs would have one effective length, and during roll the first and second torsion springs would have a shorter effective length to provide roll stiffness that is greater than jounce stiffness.

  • Patent number: 7287759
    Abstract: The piston 10 is constituted so as to rotate relative to the first cylinder 8 while moving relative to the first cylinder 8 in the axial direction when fluid is supplied to and discharged from the interior of the first cylinder 8, and the piston 16 is constituted to be incapable of rotation relative to the second cylinder 9, but capable of movement relative to the second cylinder 9 in the axial direction. Hence when fluid is supplied to and discharged from the interior of the first cylinder 8, the piston 10 is caused to rotate relative to the first cylinder 8 while moving relative to the first cylinder 8 in the axial direction, and the piston 16 is caused to move relative to the second cylinder 9 in the axial direction but prevented from rotating relative to the second cylinder 9. As a result, torsional elasticity is generated in shaft portions 4a and 5a.

The overall length of the drive shafts can be increased. When the rear wheel is vertically moved, an angle of the bend of the drive shaft can be minimized. Further, the tread of the wheels can be reduced. Therefore, the width of the body can be reduced and the mobility of the vehicle can be enhanced. In addition, the gear case can be separate from the crankcase and attached to the crankcase with the differential mechanism being housed in the separate gear case.

The second rod (67) is attached on the opposite side to a frame bracket (97) on one end and a mid section plate (34) on the telescoping rod (35) on the other end. The counter rotational arch of the second rod (67) will force the telescoping rod (35) to extend thus canceling the telescoping rod (35) arch curve travel if it were a solid rod. The overall design will limit axle (166) to frame (78) side movement while providing near straight vertical axle (166) travel.

    Abstract: A roll control actuator for a stabilizer bar includes an outer housing that is fixed to a first bar portion and a paddle member that is fixed to a second bar portion. The roll control actuator includes multiple fluid chambers with different fluid volumes. A control is used to selectively adjust roll stiffness of the stabilizer bar and includes a control valve in fluid communication with an accumulator. The first and second stabilizer bars can rotate relative to each other when the control valve is open to decrease roll stiffness and provide good ride quality. When the control valve is open, fluid flows freely between the fluid chambers. The first and second bar portions are hydraulically locked together when the control valve is closed to increase roll stiffness during cornering maneuvers. When the control valve is closed, the accumulator is isolated from the roll control actuator and fluid flow through the fluid chambers cannot occur due to differing fluid volumes.

  • Publication number: 20060273539
    Abstract: Coupling mechanism for a vehicle anti-roll bar comprising a first piece able to be fixed to a first half-bar, a second piece able to be fixed to a second half-bar, the second piece being so arranged as to be moveable in rotation about an axis of rotation A relative to the first piece. The mechanism includes at least one elastically deformable elongate element coupled to the first and second pieces so that relative rotation of the first and second pieces about the axis of rotation A causes elastic flexion deformation of the at least one elongate element, the mechanism including an actuator able to position the at least one elongate element in a first state in which the said at least one elongate element presents a first flexion stiffness for the said elastic flexion deformation, and a second state in which the said at least one elongate element presents a second flexion stiffness for the said elastic flexion deformation.

  • Patent number: 7128328
    Abstract: A mechanical stop is adapted to be mounted onto a rigid bar and includes a single piece conically shaped body having a plurality of inwardly extending projections. Each of the inwardly extending projections have a distal end that is contoured to match an outer surface of the bar. The distal ends define an opening. The conically shaped body is adapted to be plastically deformed to a substantially flat shape after being placed onto the rigid bar. The opening includes a first dimension larger than the rigid bar prior to being plastically deformed and a second dimension smaller than the rigid bar after being plastically deformed. After the conically shaped body is plastically deformed into a substantially flat shape, the distal ends will frictionally engage the outer surface of the rigid bar to secure the mechanical stop thereon.

  • Publication number: 20060186626
    Abstract: A vehicle suspension device includes a camber mechanism which imparts to the wheels a degree of freedom of the camber relative to the suspension elements. The wheels are linked to the suspension elements so that the camber movement of each wheel permits, around a mean position of the wheel, an instantaneous centre of rotation (CIR r/s). A camber connection structure transmits the camber movements of one wheel to another wheel. The instantaneous position of the instantaneous centre of rotation within the camber plane for a zero camber of a wheel satisfies the following condition: Z?(0.75)Y?(0.12158)R wherein Z and Y are the ordinate and abscissa, respectively, of the instantaneous position, and R is the wheel radius.
