A damper system for a vehicle comprises an electrically adjustable hydraulic shock absorber and a damper control module. The damper control module is disposed with and coupled to with the shock absorber. The damper control module determines a target damping state of the shock absorber based on data received from a plurality of sensors. Furthermore, the damper control module controls the shock absorber, such that the shock absorber operates at the target damping state.

The invention relates to a motor vehicle axle, in particular a torsion beam axle, the rubber-solid material bearing being constructed in a disk-like manner from at least two disks made from solid material with a rubber layer which is arranged in between, and is characterized according to the invention in that a disk which is arranged on the outside in relation to the axial direction A of the rubber-solid material bearing has a collar which is oriented so as to stand upright toward the outside.

The twist axle assembly includes a pair of spaced apart trailing arms and a twist beam of which extends in a first direction between the trailing arms. The twist beam includes a pair of end portions and a middle portion. The twist beam further has a pair of side walls and at least one additional wall that extends between the side walls. The side walls in the middle portion are generally parallel with the side walls of the end portions. The twist beam is generally hour-glass shaped with the middle portion having a first width and the end portions have a greater second width. The twist beam also tapers from the first width of the middle portion to the second widths of the end portions for gradually increasing a torsional stiffness from the middle portion to the end portions.

An embodiment rear side member of a vehicle includes a front portion extending forward in a vehicle length direction, a rear portion extending rearward in the vehicle length direction and disposed offset to an inside of the vehicle with respect to the front portion, and a transition portion in a curved shape connecting a rear end of the front portion and a front end of the rear portion and passing through both a first point configured to engage with a first arm of a first type suspension and a second point configured to engage with a second arm of a second type suspension different from the first type suspension.

Methods, apparatus, systems and articles of manufacture to calibrate a weight estimation are disclosed herein. An example apparatus comprises memory including stored instructions, and a processor to execute the instructions to determine, via a first sensor, a first load estimation of a vehicle corresponding to when the vehicle under a load condition, determine, via a second sensor, a second load estimation corresponding to when the vehicle is moving and under the load condition, and calibrate, based on a difference between the second load estimation and the first load estimation, an error of the first load estimation.

A suspension assembly for a commercial vehicle includes a first linkage, an air spring, a carriage, and a second linkage. The first linkage is pivotally coupled at a first end with a structural member of a frame. The structural member extends downwards from the frame. The air spring is coupled with the frame and a second end of the first linkage. The air spring drives the first linkage to pivot about the first end relative to the structural member. The carriage is pivotally coupled with the first linkage at a position between the first end and the second end of the first linkage. The second linkage is pivotally coupled at a first end with the structural member, and pivotally coupled with the carriage at a second end. The structural member, the first linkage, the second linkage, and the carriage define a four-bar linkage.

A motor vehicle rear axle is of the type having two longitudinal trailing arms. Each trailing arm has a stub-axle bracket at one rear end and, at an opposite front end, a substantially transverse axis of rotation defined by a first joint and a second joint which are intended to be connected to the vehicle body. A first and a second support element are located respectively in front of and behind a trailing arm on the side of its second joint. The free ends of these support elements, located in the longitudinal and vertical median plane of the rear axle, are kept at a longitudinally fixed distance by a connecting element.

There is provided a torsion beam joint structure in a torsion beam suspension including a torsion beam and right and left trailing arms connected to end portions of the torsion beam. The torsion beam has front and rear wall portions, an upper wall portion, and an opening provided at a lower side in an upper-lower direction of the vehicle. The front wall portion and the rear wall portion have a set of joint portions on their right side and left side in the vehicle width direction, by which the front wall portion and the rear wall portion are joined to each of the trailing arms. The set of joint portions includes an outer joint portion located on an outer side at a lowermost position, and an inner joint portion located on an inner side at an uppermost position. The inner joint portion is located higher than the outer joint portion.

A wheel suspension bearing is disclosed as being arranged on a member of a motor vehicle, with a bearing bushing and a bearing bushing carrier. The bearing bushing carrier incorporates the bearing bushing and is designed to be situated in the member of the motor vehicle. A wheel suspension bearing assembly, as well as a correspondingly equipped motor vehicle is also disclosed.

A twist axle assembly (20) of a vehicle includes a pair of trailing arms (22) and a twist beam (24) extending along an axis (A) between first and second twist beam ends (26, 28). The twist axle assembly (20) further includes a bushing (38) interconnected to each one of the first and second twist beam ends (26, 28) and a respective trailing arm (22) for establishing a weld-less N joint between the twist beam (24) and the trailing arm (24). In an embodiment, the twist beam (24) and bushings (38) are tubular, and the bushings (38) are press-fit or molded onto the respective first or second twist beam ends (36, 38). In a further embodiment, the trailing arms (26) define an orifice (40) aligned on the axis (A), and the tubular bushings (38) are press-fit into the orifices (40) of the trailing arms (26) to establish the weld-less joint.
