The second variant of suspension comprises a horizontally disposed frame, a steering mechanism, four identical wheel arms, each intended to be connected at one end to the hub of the corresponding wheel, and to be connected at the other end, through a bearing assembly attached to the frame, to a coupling device installed with the possibility of its free rotation, and the coupling devices form, respectively, front and rear suspension axles, the axes of the coupling devices of both axles are installed in parallel and the arms of the wheels of one axle are installed in parallel, wherein acco

The present invention relates to a method for controlling a suspension system of a motor vehicle comprising a vehicle body and a plurality of wheel pairs (2a/2b, 2c/2d), wherein the suspension system comprises spring members arranged for resilient connection between the wheels of the vehicle and said vehicle body. The method comprises the step of: monitoring at least one first parameter indicating braking of thee motor vehicle, and when said parameter indicates braking of the motor vehicle, preventing compression of the spring members of at least one wheel pair (2a/2b, 2c/2d) of the motor vehicle for counteracting a rotation of the vehicle body in connection to braking.

An axle cartridge member receives a pair of torsion stub axles at opposite lateral sides thereof. The torsion stub axles include elongated axle housings, which are sandwiched between two parallel plates to align the torsion stub axles with respect to one another. The cartridge member includes a central arch extending between the two torsion stub axles, which can provide additional ground clearance when the axle cartridge member is mounted to a trailer.

A dual rate torsion bar suspension system is connected to a control arm and includes a first rate torsion bar and a second rate torsion bar connected to one another in order to provide the suspension system with a dual rate torque resistance. A cam mechanism is employed for isolating the second rate torsion bar from the first rate torsion bar.

An elastic member is an elastic member formed of a wire having a cross section that is substantially circular, the cross section being orthogonal to a longitudinal direction, and the elastic member being expandable and contractible in a predetermined direction; and including: a first alloy portion that is made of an aluminum alloy having a tensile strength larger than 950 MPa and equal to or less than 1100 MPa at room temperature; and a second alloy portion configured to cover the first alloy portion, the second alloy portion having a thickness in a radial direction smaller than a radius of the first alloy portion, and being made of an aluminum alloy having a tensile strength of 100 MPa to 650 MPa at room temperature.

A removable spindle axle improvement using a cap attached to a rim formed along an inside surface of a torsion arm, wherein the cap seals a threaded fastener. The rim used for attachment can be a groove, collar, or a collared washer. In an alternative embodiment, a first O-ring is positioned along an end of a spindle axle tapered body and a second O-ring groove is positioned along an opposite end of the spindle axle tapered body to hermetically seal an area of the spindle axle therebetween. In a further embodiment, a first O-ring is positioned along one end of a spindle axle socket and a second O-ring is positioned along a second end of the spindle axle socket to hermetically seal an area of the spindle axle therebetween.

Disclosed herein is an axle cartridge member for receiving a pair of torsion stub axles. The axle cartridge member includes a pair of laterally opposed bases, with each base defining a cavity therein for receiving an elongated stub housing of the torsion stub axles. The axle cartridge member also includes a pair of axle mounts that each includes a lateral opening extending into the cavity defined in the respective base, and an arch including a crossbar extending at a height above the bases wherein the arch further includes a portion that extends upward from each of the bases at an angle and meets the crossbar that extends generally horizontally between the portions of the arch.

A connecting arrangement for a stabilizer of a vehicle, with at least one lever that extends transversely to a longitudinal direction. The lever has a bearing eye provided with a non-circular inner circumferential contour. A torsion-bar spring with a rotation axis extends in the longitudinal direction. The torsion-bar spring has an outer circumferential contour, at least at one end, that matches the inner circumferential contour of the bearing eye and which fits into the bearing eye. The wall of the bearing eye is cut through by at least one slit extending in the longitudinal direction, by which two opposite wall sections of the wall are separated from one another. The two wall sections are pressed against the non-circular outer circumferential contour of the torsion-bar spring by at least one releasable clamping element.

A wheel suspension for a two-track vehicle having at least one stabilizer formed as a stabilizer torsion spring rod, with the stabilizer extending in the vehicle's transverse direction and having a drive lever on at least one vehicle side, which acts upon a wheel guidance element of the wheel suspension, and having at least one suspension spring, which is tensioned with a spring preload between the vehicle body and a wheel guidance element of the wheel suspension. The suspension spring is at least partially formed as a suspension spring/torsion spring rod. The suspension spring/torsion spring rod is arranged radially within the stabilizer torsion spring rod designed as a hollow rod.
