A universal axle-hub assembly is provided for an off-road vehicle. The universal axle-hub assembly comprises a wheel hub that receives a constant velocity (CV) axle snout into an opening extending through an axle support of the wheel hub. An outboard-most portion of the opening is a splined portion that engages with similar splines disposed on an outboard-most portion of the CV axle snout. An inboard-most portion of the opening is a smooth portion that receives a smooth portion of the CV axle snout. The axle support extends through an entirety of the width of a bearing that supports the wheel hub, such that the bearing supports the smooth portion of the CV axle snout and substantially eliminates shear forces acting on the splined portion of the CV axle snout. A bearing carrier supports the bearing and may be fastened onto a trailing arm or a spindle of the off-road vehicle.

A low suspension arm strut coupling is provided for a suspension of an off-road vehicle. The suspension comprises a lower suspension arm that is hingedly coupled between a chassis of the off-road vehicle and a spindle assembly that is coupled with a front wheel. An upper suspension arm is hingedly coupled between the chassis and the spindle assembly. A strut is coupled between the lower suspension arm and the chassis. A lower pivot couples the strut to the lower suspension, and an upper pivot couples the strut to the chassis. The upper and lower pivots provide a lower center of gravity of the off-road vehicle and a relatively smaller shock angle. The lower suspension arm is reinforced to withstand forces due to movement of the front wheel and operation of the strut in response to travel over terrain.

A modular chassis is provided for an off-road vehicle to improve assembly, servicing, and repairing of a drivetrain of the off-road vehicle. The modular chassis includes a chassis to support components of the off-road vehicle. A front frame module couples with a front of the chassis, and a rear frame module couples with a rear of the chassis. The front frame module supports lower suspension arms of the off-road vehicle by way of inboard bushing joints. The front frame module supports at least a steering gear and a front differential of the off-road vehicle. The rear frame module is a tube-frame structure that supports components of the off-road vehicle. A lower portion of the rear frame module extends rearward and acutely upward to a top frame member that couples with upper side portions of the chassis. Several cross-members impart structural integrity to the rear frame module.

A welding clamp system using a fixture plate with a bulkhead that allows the clamp system to be coupled to a robotic arm. The robotic arm supplies air and electricity through pneumatic and electrical ports, enabling operation of the clamp system. The air is routed to pneumatic cylinders, which power a pneumatic clamp mechanism that moves sliding clamp fixtures along tracks. The sliding clamp fixtures press a work piece against immobile clamp fixtures, allowing a work piece to be secured and held during welding. Presence of a work piece is detected by proximity sensors which are mounted into the fixture. The clamp system allows a robotic arm to grab a work piece from a supply area, initiate and complete welding of the work piece, and then release the work piece onto a discharge station for removal of the completed work piece.

Some embodiments are directed to a duct assembly for cooling a brake assembly of a vehicle. The duct assembly can include a hollow inlet section that is disposed at the vehicle sub-frame and configured to capture air from beneath the vehicle sub-frame; and a hollow intermediate section that communicates with the inlet section so as to form a contiguous channel therewith. The intermediate section can be disposed entirely within the vehicle sub-frame. A hollow outlet section can communicate with the intermediate section so as to form a contiguous channel between the inlet, intermediate and outlet sections. The outlet section can be disposed and configured to direct the air captured by the inlet section to the front end of the brake assembly to thereby cool at least a portion of the brake assembly.

A method of assembling a front end assembly of a vehicle is provided. The method includes integrally forming a positioning and reinforcement structure having a relatively rectilinear configuration comprising a top support member, a bottom support member, a first side member and a second side member. The method also includes detachably coupling a first wing structure to the first side member. The method further includes operably mounting a first fender assembly to a first side flange of the first wing structure. The method yet further includes operably coupling a centering bracket proximate the top support member. The method also includes locating and centering the positioning and reinforcement structure to a hood with the centering bracket. The method further includes fixedly securing the positioning and reinforcement structure to a radiator support disposed rearwardly of the positioning and reinforcement structure.
