The present invention provides reinforcing braces that may be attached to the factory-supplied chassis mounts for the lower control arms of the steering knuckles of vehicles to reinforce and shield the mounts from objects below the vehicle that may be encountered when traveling through rugged terrain. The braces of the present invention are designed for the front and rear control arm mounts, each brace including a pair of parallel sturdy metal flanges that are generally perpendicularly attached to a sturdy metal lower base plate. Each flange is designed to be attached to one of the flanges of the factory-supplied chassis mounts, and has an opening therein for receiving mounting hardware and strengthening of the camber adjustment structures. The sturdy metal lower base plates may extend out and away from the flanges of the brackets to provide a lower shield to protect the chassis and mounting hardware from damage that may occur from contact with large objects that may be encountered below the vehicle. The front base plate may include an elongated section that extends toward the front of the vehicle to provide a shield for deflecting large objects as the vehicle moves forward.

A stilt part may be utilized for a suspension damper strut of the wheel suspension of a vehicle. The stilt part may comprise a shank portion extending along a longitudinal axis of the stilt part and a connecting portion adjoining an end of the shank portion. The connecting portion may be configured to connect a lower link of the wheel suspension. The shank portion may include a convex region that is bent away from the longitudinal axis. The convex region may provide clearance for a drive shaft of a wheel. The shank portion may be formed from at least two shell elements that are connected, in some cases welded, together along at least one longitudinal seam.

A suspension device according to one embodiment of the present disclosure is equipped with: an upper arm; a lower arm; a leaf spring positioned so as to extend in the vehicle widthwise direction in a manner such that an end section thereof is provided on the lower arm; a first bracket configured in a manner such that a shock absorber connected to the lower arm is connected to the outside of a side member in the vehicle widthwise direction; an upper bushing capable of transmitting force between the leaf spring and a suspension cross member; and a second bracket which is independent from the first bracket and is positioned below the side member between the side member and the leaf spring so as to be capable of transmitting the elastic force of the leaf spring to the side member via the upper bushing.

A stabilizer link includes a support bar, and ball joints. The ball joint includes a ball stud including a ball portion and a stud portion, and a housing that turnably supports the ball portion of the ball stud. The stabilizer is formed of a rod-shaped member made of metal. Mounting portions to which the stabilizer links are to be joined are respectively provided at both ends of the stabilizer. Through-holes through which the stud portions of the ball studs are to be inserted are respectively provided in the mounting portions. The stabilizer link is joined to the stabilizer by press-fitting the stud portion of the ball stud into the through-hole of the mounting portion.

An actuator device (1) for an adjustable roll stabilizer (2) of a motor vehicle, with a housing (4) that extends in the direction of a rotational axis (3) and an actuator (5) arranged in the housing. The actuator device (1) can be operated to twist two stabilizer sections (7a, 7b) relative to one another about the rotational axis (3) and the two stabilizer sections (7a, 7b) are attached to opposite ends (6a, 6b) of the actuator device (1). An engagement contour (8) is formed on the housing (4), which is suitable for immobilizing the housing during the application of torque (M1) to the housing (4) in a direction around the rotational axis (3).

An axle-to-beam connection for a suspension assembly of an axle/suspension system of a heavy-duty vehicle including an axle, a beam, and a top pad. The beam includes an alignment assembly for aligning the axle with the beam. The top pad includes an integrally-formed bump stop boss and is fixedly attached to the axle and removably attached to the alignment assembly of the beam.

A front lower arm is tiltably supported, in a cantilever manner, by an outer surface of each of side-rails provided in right and left vehicle regions and extending in a vehicle front-rear direction. The front lower arm includes: a lower arm body; an inner pivot provided at an inner end of the lower arm body in a vehicle right-left direction and supported by the side-rail; and an attachment portion to which a lower end of a shock absorber is attached, and which is joined to an intermediate section of a front upper corner portion of the lower arm body. The intermediate section is an intermediate section of the front upper corner portion in the vehicle right-left direction. A ball joint to which a knuckle is connected is attached to an outer end of the front lower arm in the vehicle right-left direction.

A torsion beam of a coupled torsion beam axle may include an external beam having a first cross-section in which an external protrusion of a middle end portion of the external beam is formed to protrude toward upward in a longitudinal direction of the external beam, and external skirt portions are vertically extended along the longitudinal direction at both end portions of the external protrusion; and an internal beam having a second cross-section in which an internal protrusion of a middle end portion in the internal beam is inserted into the external beam to face the external protrusion of the external beam, and internal skirt portions are extended in a vertical direction at both end portions of the internal protrusion, and each external surface of the internal skirt portions and each internal surface of the external skirt portions are surface-bonded in a mutually matched state. A gap is formed between an external surface of the internal protrusion and an internal surface of the external protrusion to form a closed cross-section.
