摘要： A front independent suspension assembly for outdoor power equipment includes a first joint, a first wheel coupled to the joint, a first longitudinal arm pivotably coupled to the joint, a first lateral arm pivotably coupled to the joint, and a second lateral arm pivotably coupled to the joint. The second lateral suspension arranged substantially parallel to the first lateral suspension arm. The pivotal coupling between the joint and each of the first longitudinal arm, the first lateral arm, and the second lateral arm enables the first wheel to independently displace about a vertical axis

摘要： A suspension includes a housing, a radius arm, a radius arm bush, and a shock absorber. Inclination angles θ1 and θ2 satisfy ΔF·tan θ2>M·tan θ1, in which: θ1 is an inclination angle at which a straight line coupling the center of the radius arm bush to the center of a rear wheel is inclined to a horizontal line, to lower toward the rear wheel, viewed from a side of the vehicle in a steady state; θ2 is an inclination angle at which an axis of expansion and shrink of the shock absorber is inclined to a vertical direction, to allow the shock absorber's upper end to more forward from the shock absorber's lower end; M is an unsprung mass of the suspension; and ΔF is an amount of increase in a vertical load on the rear wheel from the steady state during a shrinkwise stroke of the shock absorber.

摘要： A vehicle suspension system smoothly changes a vehicle posture with respect to a steering force and a steering angle by minimizing a kinematic roll at an initial turning stage, thereby allowing a driver to obtain the sensation of maneuvering the vehicle well. The suspension system includes a front suspension having geometry satisfying that a caster angle is +3° to +5°, a caster trail is +20 to +30 mm, an intersection point between a kingpin axis and ground is located on an inner side in a vehicle width direction of a center of a tire contact patch, and an anhedral angle of a lower arm is +2.8° to +7.2°. A rear suspension includes five links and has geometry satisfying that a virtual kingpin axis extends near the center of a tire contact patch of a rear wheel assembly and extends vertically at −2° to 0°.

摘要： A work vehicle includes a chassis. An independent linear suspension system couples to the chassis. The independent linear suspension system includes a driveshaft that couples to the chassis and to a transmission. A wheel hub couples to the driveshaft and rotates a wheel in response to rotation of the driveshaft. A spindle couples to the wheel hub. A spindle carrier couples to the spindle. The spindle carrier defines a first aperture and a second aperture. A first pin extends through the first aperture. A second pin extends through the second aperture. The first pin and the second pin block rotation of the spindle carrier. The spindle carrier moves linearly along the first pin and the second pin.

摘要： A steering system for a wheel of a vehicle comprises a pivot member having multiple pivot-node locations, and connectable at a first pivot-node location to a sub-frame of the wheel, a steering rod actuatable to rotate the wheel about a steering axis and mechanically coupled with the pivot member to be co-pivotable with the pivot member, and a suspension-connector rod having a first end that is connected to the pivot member at a second pivot-node location, and having at a second end that is connectable to a suspension arm linking the wheel of the vehicle to the sub-frame. When the steering system is installed in the vehicle, a lateral force acting upon the wheel is transmitted via the steering rod to the pivot member so as to rotate the pivot member, and the rotation is effective to transmit a substantially-vertical force vector to the sub-frame.
