A wheel carrier for a motor vehicle, with a base element carrying a wheel bearing, at least one bearing point for a detachable connection to a link provided with a link connection region, as well as at least one bearing point for a detachable connection to a link connection region provided at a link. The first link connection region and the second connection region are designed as separate components and the first link connection region and the second connection region are detachably connected by a fastener to the base element.

A vehicle drive arrangement for a vehicle of the type having differential power transmission arrangement that converts the rotatory motion of the rotatory power shaft to rotatory motion of first and second drive shafts disposed substantially orthogonal the rotatory power shaft. Primary leaf springs are each coupled at their respective centers to respective drive shafts by pivotal arrangements. The first and second primary springs may include helical springs that are used in place of, or in combination with, the primary leaf springs. Secondary leaf springs may be splayed and therefore need not be arranged parallel to the primary leaf springs. Control over vehicle kinematics is enhanced by configuring the resilience of a fulcrum bumper using resilient, rheological, or active systems. An active system will control vehicle height while stationary to facilitate loading and unloading of the vehicle.

A bolster spring for a vehicle suspension including a base plate, a top plate, elastomeric material positioned between the base plate and the top plate, a first flange comprising a pair of ears having a bottom mounting surface upwardly extending from a first end of the base plate at an angle , and one or more mounting holes positioned in the pair of ears in the first flange adapted for attachment to a pair of ears on an upwardly extending flange on a second bolster spring.

A vehicle suspension having a frame attachment portion attached to a saddle, first and second bolster springs mounted to spring mounts on an outboard side of the saddle and mounted on walls of a spring mount on an outboard side of an equalizing beam, and third and fourth bolster springs mounted to walls of a spring mount on an inboard side of the saddle and mounted to spring mounts on an inboard side of the equalizing beam, wherein upwardly extending flanges on the bottom of the first and second bolster sprints are mounted to each other using a common fastener, and wherein upwardly extending flanges on the bottom of the third and fourth bolster springs are mounted to each other with a common fastener.

An axle suspension system is suited for a trailer including a trailer frame, an axle, and left and right wheels respectively connected on opposite ends of the axle. The axle suspension system includes a swing arm pivotably securable at one end to the trailer frame and connectable at an opposite end to the axle via a connector. The connector includes a bottom surface connected to the swing arm. A spring is connected at one end to the swing arm and is connectable at an opposite end to the trailer frame. A resilient pad may be secured between the bottom surface of the connector and the swing arm. In some arrangements, a track bar may be securable at one end to the axle and may be secured at an opposite end to the swing arm.

A vehicle suspension system includes a wishbone-shaped linkage having a base, with two limbs extending from the base. Each limb is configured to support a laterally and longitudinally oriented bushing assembly, which may include a bushing assembly received by a laterally and longitudinally oriented mounting tube associated with a free end of the limb. The base includes upper and lower plates wrapping only partially around a laterally extending cross tube. A modular bushing assembly including a pair of bushing lobes and a bar pin is partially received within the cross tube, with the bushing lobes being adjustably positioned on the bar pin to allow for adjustment of the conical rate of the bushing assembly. A mounting assembly includes a pair of mount blocks secured to a vehicle axle, with the bar pin being secured with respect to the axle via the mount blocks, thereby associating the linkage to the axle.

A rigid axle having an axle carrier, at each of the axial longitudinal end regions of which one wheel hub assembly is disposed, wherein: each wheel hub assembly has a rotatable wheel flange; the axle carrier is dropped in a drop region located between its longitudinal end regions; an electromechanical functional module having an electric energy converter machine is disposed in the drop region, which electric energy converter machine is connected to at least one wheel flange for transmitting a rotation, so that the energy converter machine can be used as at least one of the functional units stated hereinafter: i) as an electric drive unit for transmitting torque onto the at least one wheel flange, and ii) as an induction unit which can be operated as a generator for generating electric energy by transmitting torque from the at least one wheel flange to the energy converter machine; the axle carrier having a dropped tubular component which is continuous between its longitudinal end regions.
