An adjustment device (1) for a chassis of a motor vehicle. The adjustment device has an actuator (2) with a housing (5) and a spindle drive, which has an axially displaceable spindle (10), with a fixed mounting (7) on the vehicle side and a connecting element (4) on the chassis side. The spindle (10) is extended in a direction of its longitudinal axis by an extension piece (11), and the connecting element (4) is attached to the outer end (11b) of the extension piece (11).

Multi-link suspension systems for vehicle are described having various linkage arms that connect to distinct points of a wheel mount. Each of the linkage arms are preferably coupled to the wheel mount via a spherical ball joint and mounted such that they can independently move with respect to the other linkage arms. A shock assembly is preferably mounted between two of the linkage arms on a separate links that is configured to vary its length based on movement of one or both of the two linkage arms.

A shock absorber mounting assembly for an off-road vehicle is provided. The shock absorber mounting assembly may provide A-arm brackets dimensioned and adapted to interconnect body and wheel framing of the off-road vehicle, wherein the lower bracket adjustably engages a lower portion of the shock absorber. The present invention also enables any model year shock absorber to be adapted to operatively associate with the steering system of any off-road vehicle of the same make and model, regardless of model year, through a shock absorber adapter bracket assembly that attaches to the original equipment manufacturer A-arms of the off-road vehicle adding the non-model year shock absorbers. The brackets may be of unitary construction.

There is provided a vehicular suspension arm used for a suspension device of a vehicle. The vehicular suspension arm according to an embodiment of the present invention may comprise: a body portion constituting a basic body of the vehicular suspension arm; and a mounting portion formed in one end of the body portion and configured to connect the vehicular suspension arm to a wheel or a vehicle body of the vehicle, wherein the body portion may have a closed-box-section structure in which a hollow inner space is defined, and the closed-box-section structure may be configured such that the body portion is formed to integrally extend around the hollow inner space.

A front upper frame connection for a space frame can comprise a top surface; a bottom surface opposite the top surface; a right-side surface; a left-side surface opposite the right-side surface; a front surface; a rear surface opposite the front surface; a pair of forward support plates provided on the front surface; a pair of forward flat mounting surfaces; and a pair of rocker attachment interfaces located on the top surface adjacent to the rear surface and respectively the right-side surface and the left-side surface. The front surface and the forward support plates can define a cutout section. Each of the forward support plates is curved and runs outward from a transverse centerline of the top surface and then forward.

A modular chassis is provided for an off-road vehicle to improve assembly, servicing, and repairing of a drivetrain of the off-road vehicle. The modular chassis includes a chassis to support components of the off-road vehicle. A front frame module couples with a front of the chassis, and a rear frame module couples with a rear of the chassis. The front frame module supports lower suspension arms of the off-road vehicle by way of inboard bushing joints. The front frame module supports at least a steering gear and a front differential of the off-road vehicle. The rear frame module is a tube-frame structure that supports components of the off-road vehicle. A lower portion of the rear frame module extends rearward and acutely upward to a top frame member that couples with upper side portions of the chassis. Several cross-members impart structural integrity to the rear frame module.

The four wheel steering vehicle utilizes a cage system that extends along the longitudinal axis to protect the driver coupled to a center rail chassis. Front and Back independent suspension links extend outward along the lateral axis pivotally connected to the wheel assemblies enabling four wheel independent suspension. A centrally located pivoting shock provides both steering control and suspension attachment for the shock and spring. The vehicle is controlled by the driver using a steering wheel, acceleration pedal, and a brake pedal. The invention provides a feeling of integration with the vehicle as the driver rolls into turns with the vehicle, while minimizing fatigue caused by the continuous resistance to centrifugal cornering forces.

A three-point suspension link has a housing supported by a ball joint so as to be rotatably and swivelably movable relative to an axle connection of the link. The link further has a captive securing arrangement functioning as a stop and extending perpendicular to the central axis of the axle connection so as to prevent a separation of the housing and axle connection in the event of failure of the ball joint. The captive securing arrangement extends perpendicular to the central axis of the axle connection operatively in two spatial directions. The three-point suspension link is formed as an axle guide link for guiding a rigid axle.

An autonomous vehicle and a suspension for the autonomous vehicle are provided. The suspension may include first and second support legs pivotally coupled to a body of the autonomous vehicle at respective pivot points, and extending in opposing directions to contact a surface upon which the autonomous vehicle moves. A biasing element biases the support legs towards the surface. A coupler couples the support legs to cause pivotal movement of one of the support legs to be mirrored in the other support leg. The coupler may cause the support legs to maintain a centerline, which extends equidistantly between the pivot points and through a sensor mounted to an underside of the body, perpendicular to the surface as the support legs pivot during movement of the autonomous vehicle.

A multi-leg control arm for a wheel suspension in a vehicle, includes first and second control arm legs coupling the multi-leg control arm to an axle carrier, and third and fourth control arm legs coupling the multi-leg control arm to a wheel carrier. The first and/or third control arm leg comprises a first elongated hole, and the second and/or fourth control arm leg comprises a second elongated hole. The first and second elongated holes are aligned with one another and define a movement path of the multi-leg control arm with respect to the axle carrier or the wheel carrier. At least one fastening element penetrates the first and second elongated holes and is adapted to fix the multi-leg control arm with respect to the axle carrier or the wheel carrier in a movement position on the movement path to set a control arm camber or a control arm track.
