A suspension includes a jounce bumper, and a striker. A spring biases the knuckle toward a first position. One of the spring and the jounce bumper is disposed forward of a kingpin axis of the knuckle and the other of the spring and the jounce bumper is disposed rearward of the kingpin axis. When in a first position, the spring is a first spring length. When in a second position, the spring is shorter than in the first position and the jounce bumper contacts the striker. When in a third position, the spring is shorter than in the second position and the jounce bumper is compressed against the striker to be shorter than in the second position. When moving between the second and third positions, the spring and jounce bumper impart moments on the knuckle that approximately balance each other to maintain a desired caster angle.

A suspension assembly for a vehicle may include a wheel support structure operably coupling a wheel to the suspension assembly, a bolt-in spring seat bracket operably coupled to the wheel support structure, and a spring supported by the bolt-in spring seat bracket and disposed between a chassis of the vehicle and the bolt-in spring bracket. The bolt-in spring seat bracket may be adjustable to change a ride height of the vehicle.

A suspension for a vehicle is configured such that, even in a situation of departing from a range in which a spring may be tensioned as a rebound state is added in a full rebound state, a lower end of the spring is continuously supported by a spring seat support arm, so as to prevent separation of the spring connecting a suspension arm to a body member.

A suspension system for a vehicle includes a spring pad coupled to a spring and configured to support the spring connecting a suspension arm and a vehicle body member of the vehicle, where the spring pad includes: a seat part coupled to an end of the spring; a guide part configured to guide upward and downward movements of the seat part; and an elastic part configured to connect the seat part and the guide part and having a length that varies when the seat part moves. In particular, the spring is consistently supported by being coupled to the seat part of the spring pad even in a situation in which an additional rebound further occurs in a full-rebound situation and the spring deviates from a range in which the spring can be extended, thus preventing withdrawal of the spring connecting the suspension arm and the vehicle body member.

A method for creating a roller spring perch has steps for burning a rubber bushing out of an existing spring perch that has the rubber bushing implemented between an existing mounting shaft, and an existing tube mounted through a frame, removing the existing tube from the frame, preparing a new tube counterbored at each end to accommodate ball bearings, machining a new mounting shaft from the existing mounting shaft, assembling the new mounting shaft to the new tube with ball bearings, and joining the new tube with new mounting shaft and bearings to the frame.

Independent wheel suspensions for a motor vehicle are described herein. An example independent wheel suspension includes a link to be pivotably coupled to a vehicle body of the motor vehicle via a first flexible pivot bearing and a second flexible pivot bearing. The first and second flexible pivot bearings form a pivoting axis. The link has a wheel attachment point to which a vehicle wheel is to be coupled. The example independent wheel suspension also includes a spring to be disposed between the link and the vehicle body. The spring is configured to produce a force component on the link that is directed outward along a transverse axis of the motor vehicle and that increases during compression.

A suspension includes a jounce bumper, and a striker. A spring biases the knuckle toward a first position. One of the spring and the jounce bumper is disposed forward of a kingpin axis of the knuckle and the other of the spring and the jounce bumper is disposed rearward of the kingpin axis. When in a first position, the spring is a first spring length. When in a second position, the spring is shorter than in the first position and the jounce bumper contacts the striker. When in a third position, the spring is shorter than in the second position and the jounce bumper is compressed against the striker to be shorter than in the second position. When moving between the second and third positions, the spring and jounce bumper impart moments on the knuckle that approximately balance each other to maintain a desired caster angle.

A rear axle of a two-track vehicle includes a plurality of wheel-control links with at least one spring link for supporting a bearing spring on a vehicle body of the vehicle, which wheel-control links connect a rear wheel of the vehicle to a rear axle carrier. The rear axle carrier includes at least two longitudinal members oriented at least approximately in the longitudinal direction of the vehicle and at least one crossmember oriented at least approximately in the transverse direction of the vehicle. The rear axle carrier is attached to the vehicle body via two bearing points on each side of the vehicle, as viewed with respect to the longitudinal center axis of the vehicle. The spring link and at least one of the wheel-control links are attached to the longitudinal member. The attachment of the spring link to one longitudinal member in each case is arranged, as viewed in the travel direction of the vehicle, upstream of the center of the distance between the bearing points arranged on a common side of the vehicle.

A vehicle wheel suspension includes a suspension spring and an additional spring element. The additional spring element is disposed in a working chamber of a hydraulic cylinder. The working chamber, in hydraulic terms, is configured to be completely shut off by a check valve and the volume thereof with an opened check valve while activating a vehicle drive apparatus with braked vehicle wheels being variable by the anti-dive angle and/or the anti-squat angle. For such a volumetric variation of the working chamber, a hydraulic medium is flowable through the opened check valve.

A chassis control arm for a wheel suspension has a control arm body, a spring abutment and an actuator which is arranged between the control arm body and the spring abutment and with which the position of the spring abutment relative to the control arm body can be adjusted. The actuator comprises a lifting gear which is configured as a movement thread and which includes a lifting spindle on which the spring abutment is arranged or on which the spring abutment is axially movably mounted.
