A vehicle body includes a rocker panel elongated along an axis. The vehicle body includes a pillar fixed to the rocker panel and elongated in a direction transverse to the axis. The rocker panel includes a first flange and a second flange. The first flange and the second flange are on opposite sides of the pillar and spaced from each other in a direction parallel to the axis. The vehicle body includes a reinforcement fixed to the first and second flanges.

A reinforcing structure of a vehicle frame member includes: ribs that integrally connect standing wall portions, that are formed at a planar portion of a vehicle frame member, to one another, and that reinforce the planar portion; portions of gradually changing thickness that are formed at connected portions of the ribs with the standing wall portions; portions of gradually changing height that are formed at the connected portions of the ribs with the standing wall portions; first curved portions that are formed at the portions of gradually changing thickness; second curved portions that are formed at the portions of gradually changing thickness; third curved portions that are formed at the portions of gradually changing height; and fourth curved portions that are formed at the portions of gradually changing height.

Disclosed herein is an article comprising a first metal layer; a second metal layer that is chemically different from the first metal layer; and a third metal layer disposed between the first metal layer and the second metal layer and contacting both the first metal layer and the second metal layer; where the third metal layer is chemically similar to either the first metal layer or the second metal layer; where at least two metal layers that are chemically similar are welded together through a clearance opening located in a metal layer that is not chemically similar to the at least two metal layers.

An auxiliary frame for supporting elements of a front suspension of a motor-vehicle includes two end supports for connection thereto of suspension elements and a structure which connects the end supports to each other. The connecting structure has a front beam and a rear beam which connect the end supports to each other. The rear beam has an arch-like configuration which extends substantially in a horizontal plane, with a central portion arranged in a forwardly spaced position. The front beam of the connecting structure has a configuration which is substantially straight and perpendicular to a vertical median plane of the auxiliary frame. The front beam and the rear beam are longitudinally spaced from each other and connected to each other by at least two lateral longitudinal arms spaced from each other and which have a configuration substantially straight and parallel to the vertical median plane of the auxiliary frame.

An All-Terrain Vehicle with a frame comprising an arcuate shape or an elevated portion with an apex. In one embodiment, the arcuate shape or elevated portion with an apex is located between a rear axis and a front axis such that there is additional clearance over a typical non arcuate frame or a flat frame for a given ride height. The arcuate shape may be a lateral arcuate shape. The frame may also provide for additional structural strength. The frame may also include the ability to attach periphery accessories such as an engine cage, a passenger cage, trailing arms, power train and transmission.

A reinforcement assembly for a rear rail of a vehicle is disclosed that includes inner and outer bulwark brackets. The brackets include radially extending walls that are welded to inner and outer walls and a bottom wall of the rear rail. A barrel nut is assembled between the bulwark brackets and retained by the bulwark brackets at an intermediate location between the side walls of the rear rail.

A vehicle body structure includes a front side member, a body attachment structure and an off-center impact structure. The front side member defines a hollow interior, an outboard wall and an inboard wall. The body attachment structure is attached to the outboard wall of the front side member. The off-center impact structure has a first end portion, a second end portion and a main section extending from the first end portion to the second end portion. The first end portion extends through an outboard forward opening and into the hollow interior of the front side member and is rigidly connected to the front side member forward of the body attachment structure. The second end portion is attached to the front side member at a location rearward of the body attachment structure with the main section extending outboard of the body attachment structure.

A frame structure of a utility vehicle includes: a pair of left and right bottom first frame and bottom second frame that extend in a front-rear direction and support a floor plate; a bottom front frame that couples a front end of the bottom first frame and a front end of the bottom second frame and extends linearly in a vehicle width direction and to which a first support member of a gear box for front wheels is welded; and a bottom rear frame that couples a rear end of the bottom first frame and a rear end of the bottom second frame and extends linearly in the vehicle width direction and to which a second support member of a gear box for rear wheels is welded, the bottom front frame and the bottom rear frame each being a cylindrical pipe frame.

A utility vehicle includes a plurality of ground-engaging members, a frame supported by the ground-engaging members, and a plurality of body panels supported by the frame. The utility vehicle also includes a radiator supported on a rear portion of the frame. Additionally, the utility vehicle includes an air intake assembly partially supported by an upper portion of the frame.

A suspension structure of a utility vehicle includes a frame, a wheel, and a trailing arm including an arm extending anteroposteriorly and supported by the frame, a knuckle rotatably supporting the wheel, and a rotary shaft configured to angularly displace the knuckle in a vehicle width direction with respect to the arm.
