A subframe assembly for a vehicle and a method for manufacturing the same is disclosed. The subframe assembly includes a crossmember, a straight arm, and a side bracket. The crossmember includes an end bracket disposed at an end thereof. The straight arm is received into and metallurgically bonded to the end bracket of the crossmember. The side bracket includes a base, and a rear bracket arm. The base is metallurgically bonded to a side of the straight arm adjacent to the end of the crossmember. The rear bracket arm extends from an end of the base and defines a hole adapted to receive a screw or pin for connecting a control arm of a wheel suspension to the subframe assembly. The rear bracket arm is at least partially received into and metallurgically bonded to the end bracket of the crossmember.

An axle support for a vehicle has a left longitudinal member for fastening a left wheel suspension, a right longitudinal member for fastening a right wheel suspension, and at least one cross member connecting the longitudinal members. The cross member is formed by two shells placed on top of each other. The two shells are detachably interconnected in a non-destructive manner. At least one component of an axle steering system is installed in the hollow space between the two shells.

A hanger for axle/suspension systems of a heavy-duty vehicle includes an outboard wall spaced apart from an inboard wall. The outboard wall is connected to the inboard wall via a front wall. The outboard wall and the inboard wall are formed with an aligned opening extending through the outboard wall and the inboard wall. A top plate connected to the inboard wall, the outboard wall and the front wall. The top plate is formed with at least one circular opening or laterally oriented oblong-round opening and at least one laterally slotted opening. A fastener is disposed through the at least one circular opening or oblong-round opening. A second fastener is disposed through the at least one laterally slotted opening for mounting the hanger to a frame of the heavy-duty vehicle.

A steering system for a wheel of a vehicle comprises a pivot member having multiple pivot-node locations, and connectable at a first pivot-node location to a sub-frame of the wheel, a steering rod actuatable to rotate the wheel about a steering axis and mechanically coupled with the pivot member to be co-pivotable with the pivot member, and a suspension-connector rod having a first end that is connected to the pivot member at a second pivot-node location, and having at a second end that is connectable to a suspension arm linking the wheel of the vehicle to the sub-frame. When the steering system is installed in the vehicle, a lateral force acting upon the wheel is transmitted via the steering rod to the pivot member so as to rotate the pivot member, and the rotation is effective to transmit a substantially-vertical force vector to the sub-frame.

An axle component for a motor vehicle axle is disclosed having rim holes for the insertion of a rubber-metal bearing. The upper and lower collars of the two rim holes are oriented in the same direction. An outwardly oriented collar is set back into the interior space in relation to an outer wall of the axle component.

A vehicle suspension extension apparatus. Implementations may include an extension framework of rigid metallic materials having at least one mounting hole through the extension framework at a location in the extension framework in alignment with a mounting feature of a suspension structure of a truck and is also in alignment with a mounting feature of a body of the truck.

A vehicle lower portion structure includes a suspension member, an inclined portion, and a receiving portion. The suspension member is disposed at a lower portion of a space portion at a vehicle body front side of a vehicle cabin. The inclined portion is provided at a vehicle body structural member that is further toward a vehicle body rear side than a rear portion of the suspension member, and has an inclined surface that, when the suspension member moves toward a vehicle body rear side, guides the suspension member toward a vehicle body lower rear side. The receiving portion has a receiving surface that, when the suspension member moves toward a vehicle body obliquely rear side as seen in plan view, receives the suspension member.

A subframe assembly for a vehicle and a method for manufacturing the same is disclosed. The subframe assembly includes a crossmember, a straight arm, and a side bracket. The crossmember includes an end bracket disposed at an end thereof. The straight arm is received into and metallurgically bonded to the end bracket of the crossmember. The side bracket includes a base, and a rear bracket arm. The base is metallurgically bonded to a side of the straight arm adjacent to the end of the crossmember. The rear bracket arm extends from an end of the base and defines a hole adapted to receive a screw or pin for connecting a control arm of a wheel suspension to the subframe assembly. The rear bracket arm is at least partially received into and metallurgically bonded to the end bracket of the crossmember.

A front body structure of a vehicle includes a pair of left and right hinge pillars, a pair of left and right front suspension dampers that are provided in desired positions on an inner side in a vehicle width direction of the hinge pillars and on a vehicle front side of the hinge pillars, a pair of left and right suspension housings that have damper mount parts, and a pair of left and right apron reinforcements to which upper ends of the suspension housings are joined. The apron reinforcements are formed in shapes extending substantially linearly from the rear ends thereof toward the vehicle front side and an inner side in the vehicle width direction through an outer side in the vehicle width direction of the damper mount parts in plan view.

An independent wheel suspension for a two-track vehicle has a wheel carrier, a vibration damper designed and arranged in the manner of a damper strut, and a leaf spring element, which has, in particular, a fiber composite material or is made from a fiber composite material. The leaf spring element is oriented at least approximately in the transverse direction of the vehicle and is designed to provide a suspension function and, together with the vibration damper, to guide a vehicle wheel fastened to the wheel carrier when the independent wheel suspension is installed in a vehicle for functional usage. The leaf spring element is connected, on the wheel carrier end, to the wheel carrier via two rubber bearings, each having a bearing axis and a central bearing point, so as to be rotatable about the respective bearing axis of each rubber bearing and is designed to be connected, on the vehicle body end, to an axle support in a torsion-resistant manner and/or directly to a vehicle body.
