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°.

A suspension system including a Chebyshev-Lambda (CL) mechanism, at least one linear motion mechanism and a spring-damper assembly, the CL mechanism including a suspension-arm, a support-arm and a first rotating-arm, an end of the rotating-arm being configured to be coupled with a reference frame at an anchoring-node, an operational-end of the suspension-arm being configured to be coupled with a suspended-mount at a first node, an end of the support-arm being configured to be coupled with the reference frame at a support-anchoring-node, the linear motion mechanism configured to be coupled with the reference frame via at least one anchoring node, an end of the linear motion mechanism being configured to be coupled with the suspended-mount at a second node, and the spring-damper assembly including at least one spring and at least one damper, wherein respective first and second ends of the spring and the damper are coupled between two points.

Provided is a work vehicle including a wheel support member including an axle that supports a pair of left and right travel wheels; a link mechanism that is provided spanning between a vehicle body and the wheel support member, and that supports the wheel support member such that the wheel support member can be raised and lowered; and a suspension mechanism that is provided spanning between a suspension support section formed on the vehicle body and the wheel support member, and that elastically supports the wheel support member.

A rear suspension for a three-wheeled reverse trike includes a front lever arm pivotably affixed to a frame pivotable about a front lever arm pivot axis. A slider is translatably attached to the front lever arm. A first pushrod is pivotably connected at a first end to the slider and pivotably connected at a second end to at least one of a front upper or lower control arms for the front wheels. A rear lever arm is pivotably affixed to the frame and pivotable about a rear lever arm pivot axis, the rear lever arm extending to a rear lever arm distal end. A rod pivotably connects the front and lever arms. A first pivotable end of the rear upper control arm is pivotably connected to the rear lever arm distal end, and a second pivotable end of the rear upper control arm is pivotably connected to a rear spindle.

A steering system for a wheel of a vehicle includes a pivot member having multiple pivot-node locations. The pivot member is connectable at a first pivot-node location to a sub-frame of the wheel. A steering rod is actuatable to rotate the wheel about a steering axis and is mechanically coupled with the pivot member to be co-pivotable with the pivot member. A suspension-connector rod has a first end that is connected to the pivot member at a second pivot-node location, and has 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 a 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.

Disclosed is a corner module apparatus for a vehicle. The corner module includes a driving unit that provides drive power to a wheel of the vehicle, a braking unit that interferes with rotation of the wheel to generate braking power, and a suspension unit connected to the driving unit. The suspension unit absorbs shock transferred from a road surface. The corner module also includes a steering unit connected to the suspension unit and rotated about a steering axis inclined with respect to the wheel. The steering unit adjusts a steering angle of the wheel.

A wheel suspension (1), for a motor vehicle, having a hub carrier (2) for holding a wheel (3), a wheel-guiding link (4) for an articulated connection of the hub carrier (2) to a body (6), and a steering rod (8) for steering the wheel (3). The hub carrier (2) and the wheel-guiding link (4), for steering the wheel (3), are pivotally connected to each other such that the hub carrier (2) can be swiveled about a steering axis relative to the wheel-guiding link (4). The hub carrier (2) is directly connected to the wheel-guiding link (4), in a first connection area (20), and the hub carrier (2) is indirectly coupled to the wheel-guiding link (4), in a second connecting area (21), via an integral link (5) connected to a chassis element (12).

There is described a wheel axle for an agricultural vehicle such as a combine harvester. The wheel axle has at least one wheel suspension (32a) arranged to maintain a wheel axle parallel to the supporting surface, through use of a linkage arrangement (36, 38, 40) which is pivotally coupled to the axle frame (30). The configuration of the wheel suspension allows for the wheel axis to passively follow the surface profile, as any loads transmitted through the wheel carrier act to level out the wheel suspension to align with the underlying surface. As the wheel axle is adjusted to lie parallel with the underlying surface, accordingly the ground-contacting surface area of the associated wheels is maximised.
