An all-terrain vehicle is provided comprising a chassis, four wheels and a passenger compartment that includes a passenger seating structure. The vehicle additionally comprises a drivetrain operatively connected to at least one of the wheels comprising at least one drive shaft and at least one torque transfer device. Furthermore the vehicle includes a prime mover that is mounted to the chassis entirely forward of a front edge of the seating structure and operatively connected to the drivetrain. The prime mover is structured and operable to provide motive force to at least one of the wheels.

A body for a vehicle includes a bridge member having a pipe shape of an open cross-sectional structure in which one side thereof is opened, having end portions formed in a closed shape, and having an intermediate portion formed to be bent, and at least two members, wherein the bridge member is connected to a weak rigidity portion between the at least two members of the body.

A vehicle body includes a frame member formed to have a tubular shape in an open cross-sectional structure in which one side surface thereof is opened. A fastening portion is formed in a shape to close an opening portion at an end of the frame member. The fastening portion is configured to be fastened to another frame member by a fastener in a surface-contact state.

Embodiments relate to an off-road vehicle comprising a frame, including at least one cargo box support member, a suspension movably coupled to the frame, a passenger compartment, an engine, a transmission operatively coupled to the engine, and a cargo box. The cargo box includes a floor and a plurality of upwardly extending sidewalls, wherein at least a portion of the cargo box floor extends over the at least one cargo box support member and wherein the cargo box is removably coupled to the at least one cargo box support members and is removable from the off-road vehicle via the removal of fewer than eight fasteners.

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 vehicle load-bearing structure includes a cell made of composite materials and composed of a plurality of components joined to each other by at least one joining system to form a single structure; the cell is made up of a number n of components between 3 and 8, that is 3<n<8.

A lower body for a vehicle includes front and rear main bodies each including pipes, a pair of first longitudinal members extending in a forward/rearward direction and spaced apart from each other in a transverse direction, a first transverse member extending in the transverse direction and connecting the first longitudinal members, and mounting parts each having an outer side to which the first longitudinal members and the first transverse member are coupled, and a pair of lower body main members connecting the outer sides of the mounting parts and two opposite sides of upper ends of the front and rear main bodies spaced apart from each other, the pair of lower body main members each having a pipe shape and extending forward and rearward to constitute upper side members of the front and rear main bodies and defining an overall length of the vehicle.

An off-road vehicle includes a frame, a front suspension, and a rear suspension. In some examples of the off-road vehicle, the rear suspension includes trailing arms with are pivotally attached to the frame rearward of an operator area. Further, the frame can include a front subframe assembly and a rear subframe assembly which are easily removable from the main frame of the vehicle to permit access to various components of the off-road vehicle.

Systems and methods for transporting small, dense cargo over roadways via a specialized transportation trailer are provided. The disclosed transportation trailer includes a space frame including a lower central portion designed to directly receive and support the cargo that is being carried by the trailer, as well as an upper portion that extends above the height of the cargo. The space frame also includes lower side portions that extend longitudinally in opposite directions from the lower central portion to connect the space frame to the wheels and trailer hookup of the transportation trailer. The space frame may further include a truss structure formed between the lower central portion and the upper portion to increase the rigidity of the trailer. The transportation trailer is designed to minimize the height of the cargo's center of gravity, increase trailer rigidity, increase cargo capacity, and maximize ground clearance compared to existing trailer designs.
