Abstract:
A supplementary vehicle spring assembly for a leaf spring of a vehicle is provided, the leaf spring defining a fixed end and a free end. The supplementary vehicle spring assembly comprises a first tension spring arrangement fitted to the fixed end of the leaf spring, a second tension spring arrangement fitted to the free end of the leaf spring, and a bracket arrangement proximate an axle of the vehicle, the bracket arrangement connecting the first and second tension spring arrangements. The first and second tension spring arrangements each comprise a connector arm for securing the arrangements to the respective ends of the leaf spring, a first connector rod extending from the connector arm and being secured to a first end of at least one tension spring, and a second connector rod extending from a second end of the tension spring, the second connector rods securing the first and second tension spring arrangements to opposite ends of the bracket arrangement.
Abstract:
An elastomeric spring suspension is described for supporting a longitudinally extending vehicle frame rail above first and second axles forming a tandem axle configuration. The suspension includes a frame hanger assembly mounted to the vehicle frame rail. The frame hanger assembly has two full spring modules, each of which includes two shear springs, a progressive spring rate load cushion having a pyramidal shape with a flattened top surface and a spring mount for mounting the springs. A saddle assembly is connected to the spring mount, and an equalizing beam is connected to the saddle assembly and further connected to the axles. The spring rate for the suspension increases almost linearly as a function of sprung load, resembling a pneumatic suspension. Accordingly, the suspension exhibits excellent ride quality, without sacrificing roll stability.
Abstract:
A structural element comprising a vehicle suspension control arm is constructed from a complex, single piece, sheet metal stamped component formed from a material of uniform thickness. The stamping is configured with the correct plan view shape and formed into an I-beam cross-section comprising a central web portion and two flange portions. The central web portion is configured as a single material thickness and the flange portions comprise upstanding and downstanding closed sections with a continuous double returned segment. The open ends of the sheet metal terminate at or near the central web portion and are welded to the web portion, and in an alternative embodiment also to the continuous double returned segment, to create a favorable structural I-beam section with flange portions twice the thickness of the web portion.
Abstract:
An upper support apparatus for use in a suspension system of a vehicle is disclosed, wherein the apparatus includes an upper support plate defining at least one aperture, the upper support plate coupled to a body of the vehicle. The upper support apparatus further includes a resilient member coupled to an underside of the upper support plate, wherein at least one portion of the resilient member is adapted to protrude through the at least one aperture and wherein the at least one portion of the resilient member prevents direct contact between the upper support plate and the body of the vehicle.
Abstract:
A suspension arm may include first and second metal housings, a metal connecting portion including first and second panels, wherein the metal connecting portion connects the first and second metal housings at distal ends thereof respectively, and wherein a burred first panel connecting portion and a burred second panel connecting portion are formed respectively to the first and second panels, and a reinforcement member wrapping the first and second metal housings and the metal connecting portion, wherein the first panel and the second panel are connected by inserting the burred second panel connecting portion into the burred first panel connecting portion.

Abstract:
There is provided a torque rod bracket assembly for an axle assembly of a motor vehicle. The torque rod bracket assembly has a torque rod mounting bracket engaging plates with a plate connector. The torque rod mounting bracket has a base, a first sidewall, and a second sidewall. A receiver wall located between the first sidewall and the second sidewall has a centrally located recess. Slots are located in the receiver wall between the recess and the sidewalls. Axle mounts mount the torque rod bracket assembly to the axle housing of the axle assembly.
Abstract:
The arm (12) comprises a pair of transverse rods (16, 18) articulated at their outer ends (24, 28) to the wheel-carrier of a vehicle wheel and at their inner ends (26, 30) to the vehicle body, and at least one pair of connecting elements (20, 22) which connect the rods (16, 18) to one another and are preferably formed as blade-like or plate-like elements, in such a manner that their bending stiffness in a plane is higher than their bending stiffness in a direction perpendicular to that plane. The arm (12) is capable of controlling two translational degrees of freedom (DOFx, DOFy) along the axes of the rods (16, 18) and, by virtue of the geometry and torsional stiffness of the rods (16, 18), as well as of the geometry and bending stiffness of the connecting elements (20, 22) in their plane, a first rotational degree of freedom (DOFθy) about a first, mainly transverse and horizontal axis (ESAy). According to the invention, the rods (16, 18) converge, preferably towards the outside of the vehicle, in such a manner that the arm has an elastic centre (EC) located outside its physical envelope and is thus capable of controlling, by virtue of the geometry and bending stiffness of the rods (16, 18), as well as of the geometry and bending stiffness of the connecting elements (20, 22) in the direction perpendicular to their plane, a second rotational degree of freedom (DOFθz) about a second, mainly vertical axis (ESAz).

Abstract:
A control arm for vehicle suspension systems has first and second rigid arm plates having first and second apertures extend laterally through opposing faces of the body adjacent opposite ends thereof. The arm plates are disposed in a mutually parallel, laterally spaced apart and aligned relationship. The first apertures are generally concentric and the second apertures are generally concentric. First and second spacers each have a rigid body with opposite ends and a central bushing aperture extending therebetween. The spacers are disposed between the arm plates adjacent opposite ends thereof. The central bushing aperture of the spacers is positioned generally concentrically with the apertures. Also included is a related method for making vehicle suspension links from ultra high strength steel.
