An electrically powered suspension system includes: an actuator that generates a load for damping vibration of the vehicle body; an information acquisition part that acquires information on a sprung state amount and a road surface state; a target load calculation part that calculates a first target load related to skyhook control based on the sprung state amount and calculates a second target load related to preview control based on the road surface state; and a load control part. The target load calculation part is further configured to calculate a third target load related to virtual spring force control based on a stroke position and to calculate a combined target load into which the first target load, the second target load, and the third target load have been combined. The load control part performs load control of the actuator using the combined target load.

Aspects of the present invention relate to a system (100) for a vehicle (1), the system comprising: fluid bump stop mounting brackets (200) each configured to receive a fluid bump stop (400); a rear subframe (300) for a multilink rear suspension arrangement of a vehicle (1) having a unibody chassis (10); and lower arms (308) of the multilink rear suspension arrangement of the vehicle; wherein the rear subframe extends laterally (y) and comprises an upper spring seat (302) at each lateral side of the rear subframe, wherein each upper spring seat is configured to receive an upper end of a spring (500), wherein the rear subframe comprises a central mounting space (304) for a drivetrain component (600), wherein the rear subframe further comprises one or more lower arm mounting points (306) at each lateral side of the rear subframe, for the lower arms, wherein each lower arm comprises a lower spring seat (322) configured to receive a lower end of the spring, wherein either the lower spring seats or the upper spring seats comprise the fluid bump stop mounting brackets, and wherein the other of the lower spring seats or the upper spring seats comprise bump stop landing pads (310) each configured to contact one of the fluid bump stops when suspension compression is above a threshold.

An axle/suspension assembly for a heavy-duty vehicle supported by a frame and a hanger includes a beam, an axle, and a bumper. The axle is supported by a first portion of the beam for pivotal movement of the beam relative to the hanger at a pivot joint. The first portion of the beam is located on a first side of the pivot joint. The bumper is fixed to at least one of the frame, the hanger, and a second portion of the beam. The second portion of the beam is located on an opposite second side of the pivot joint. The bumper includes a portion for contacting structure of at least another of the frame, the hanger, and the beam to limit pivotal movement of the axle in one direction.

According to one embodiment a shock absorber assembly is provided that comprises a top mount and a jounce bumper. The jounce bumper includes a main body manufactured of an elastic material and a fixing element manufactured of a second material harder than the former. The jounce bumper is removably attached to the top mount through use of a movable retaining element housed in the fixing element, retaining said fixing element in the top mount in a first locking position and releasing said fixing element in a second unlocking position.

End member assemblies are dimensioned for securement to an end of a flexible spring member for forming gas spring assemblies. An end member assembly can include an end member body and at least one connector fitting. The end member body includes a base section and a cap section that are secured together at a single flowed-material joint. The base section and the cap section together at least partially define a reservoir chamber within the end member body. The at least one connector fitting is at least partially embedded within the end member body. Gas spring assemblies including at least one end member assembly and suspension systems including at least one gas spring assembly are also included.

In a rear suspension device of an automotive vehicle, a shock absorber is provided perpendicularly to a H-shaped lower arm in a side view, respective axis of resilient bushes of pivotal portions which pivotally support upper and lower arms at a vehicle-body side are configured to be parallel to a standard line which extends in a vehicle longitudinal direction in a plan view, and an imaginary axial line which interconnects respective centers of front and rear connection portions, via which the lower arm is connected to a wheel side, is configured to extend obliquely forward and inward relatively to the vehicle longitudinal direction.
