Steering suspension module including a shock absorber strut, a suspension upright, an outer ring of a wheel hub unit attached integrally to a front face of the suspension upright, and a ball joint for articulation with a control arm; wherein the suspension strut consists of a cup-shaped body made entirely of continuous, sheared and bent metal sheet, and the outer ring is provided integral in one piece with, and radially cantilevered from, a steering arm extending transversely cantilevered from the cup-shaped body, on the side of the cup-shaped body; the shock absorber strut is constrained within a first seat of the cup-shaped body and the ball joint is made as an independent unit constrained integrally with a second seat of the cup-shaped body in a position facing the first seat, the ball joint projecting inferiorly cantilevered from the cup-shaped body.

A suspension coil spring that is to be installed between an upper side pedestal and a lower side pedestal of a strut type suspension for a vehicle includes a coil spring main body such that, in an installation state, an upper coil end is disposed on the upper side pedestal and a lower coil end is disposed on the lower side pedestal, the upper side pedestal and the upper coil end contact at two upper contact points, and the lower side pedestal and the lower coil end contact at one lower contact point. The two upper contact points are separated in a front-to-rear direction of the vehicle. The one lower contact point is disposed at a position that is in a direction toward outside the vehicle from a plane that passes through the two upper contact points and that is parallel to a coil central axis.

A suspension linkage for a motor vehicle includes an extruded body having a first wall and a longitudinal length. An extruded feature is disposed on the first wall of the extruded body and extends along the longitudinal length. The extruded feature has a cross-sectional profile configured to control a flexural rigidity of the suspension linkage.

A machine includes a chassis, a plurality of ground-engaging elements supporting the chassis above a ground surface, a motor for driving at least one of the ground-engaging elements and a plurality of assemblies supporting the chassis on the ground-engaging elements. Each of the assemblies is configured to selectively raise and lower the chassis relative to the ground surface and includes a first attachment component for attaching the assembly to one of the ground-engaging elements, a second attachment component for attaching the assembly to the chassis, an adjustment component for shifting the first attachment component between a plurality of operating positions relative to the second attachment component. A control system allows an operator to remotely control the adjustment components of each of the assemblies.

An electrically powered suspension system includes: an electromagnetic actuator; an information acquisition unit configured to acquire time-series information related to stroke position of the electromagnetic actuator, information on stroke velocity, and an amount of change in stroke of the electromagnetic actuator and information on a stroke direction based on the time-series information; a damping force calculation unit configured to calculate target damping force based on the information on the stroke velocity; and a drive control unit configured to control driving of the electromagnetic actuator using target driving force obtained based on the target damping force. The damping force calculation unit calculates equivalent friction compensation force based on the amount of change in the stroke and the information on the stroke direction, and corrects the target damping force based on the calculated equivalent friction compensation force. The equivalent friction compensation force has elastic force component and dynamic friction force component.

An electromechanical brake system having a suspension control function. The electromechanical brake system includes: an electromechanical brake connected to each wheel of a vehicle to brake the vehicle, a suspension configured to control suspension of the vehicle, a motor configured to provide driving force to the electromechanical brake or to the suspension, a first clutch configured to connect the electromechanical brake and the motor to each other, a second clutch configured to connect the suspension and the motor to each other, and a controller configured to output a control signal for controlling the motor to be connected to one of the first clutch and the second clutch based on a state signal of the vehicle.

A motor vehicle chassis is provided having a base structure that can be hydraulically adjusted in level between a raised and a lowered position. A hydraulic adjuster is assigned to one of the two foot points of the corresponding suspension spring in each of the four wheel suspensions. At least two of the adjusters can be pressurized in parallel by a common hydraulic aggregate comprising a tank and a motor-pump unit and activated by a control unit. The at least two hydraulic adjusters that can be pressurized by the common hydraulic aggregate communicate hydraulically with the accumulator chamber of a spring-piston accumulator, which has at least one piston-position transmitter linked by signal transmission to the control unit.

An independent suspension system includes a steering unit configured to be controlled to adjust the steering angle of a wheel, a shock absorber engaged with the wheel in order to absorb external impacts applied to the wheel and including first and second shock absorbers, each of the first shock absorber and the second shock absorber arranged in a forward-rearward direction on opposite side surfaces of the wheel, respectively, and a link unit disposed between the shock absorber and the steering unit in order to vary the distance between the wheel and the steering unit. The link unit includes a first upper arm disposed between the first shock absorber and the steering unit, a second upper arm disposed between the second shock absorber and the steering unit, and a ground clearance adjustment unit engaged with the first and second upper arms and configured to vary the distance therebetween while varying the distance between the wheel and the steering unit at the same time.
