The present disclosure provides a chassis comprising a frame, two hanging units symmetrically provided at both sides of the frame, and a front guiding wheel and a rear universal wheel provided below the frame, wherein each of the hanging units comprises a mounting rack fixedly connected to the frame, a hanging rack slidably connected to the mounting rack, and a driving wheel rotatably connected to the hanging rack, and the front guiding wheel is provided with a first driving motor, and the driving wheel of each hanging unit is driven by a second driving motor, and wherein a closed loop speed control system is formed between the first driving motor and both second driving motors, such that a rotational angle of the front guiding wheel is adjustable via the first driving motor when revolving speeds of both second driving motors are changed.

An off-road vehicle includes a powertrain assembly having an engine and a steel belt continuously variable transmission. Portions of the powertrain assembly are supported at a rear portion of the vehicle and are positioned relative to other components of the vehicle also supported at the rear portion of the vehicle. The vehicle also is configured for various operating modes.

A self-supporting underframe for a vehicle, the vehicle, and a production method thereof. The underframe has two elongate monocoques arranged parallel and spaced apart from each other and at least 50% closed on at least four sides, wherein the monocoques each have a single-part, trough-like element having at least one lower base and two side walls extending upwards from the base. At least one cover element closes the trough-like elements over at least 50% of the longitudinal extent of the particular trough-like element. The at least one cover element of each of the two monocoques in each case includes at least one cross-strut cover element, and the cross-strut cover elements of the two monocoques are designed as a common, single-part cross-strut cover element spanning an intermediate space located between the trough-like elements of the monocoques. The cover elements are fixedly connected to the side walls of the monocoques.

A modular transportation system to transport one or more persons and/or objects. The system may include a pod with wall segments that mount together to form an interior space to house the one or more persons and/or objects. The wall segments are modular and configured to connect together in a variety of different configurations to selectively configure the interior space. Vehicles are each configured to individually connect to the pod and to transport the pod from a first location to a second location. At least one of the vehicles is configured to transport the pod by land and at least one of the vehicles is configured to transport the pod by air.

A skid plate module for a vehicle. The skid plate module may include first and second pillars that may extend from a skid plate. The first and second pillars may be disposed along a center plane of the skid plate and may be adapted to be mounted to a chassis of a vehicle. A lower control arm, a mounting bracket subassembly, or both may be mounted to the first and second pillars.

A utility vehicle powertrain enclosure includes an engine and a transmission mounted to a carrier under a utility vehicle cargo box and substantially enclosed by the carrier and a plurality of panels. The carrier has a forward end pivotably attached to a frame member of the utility vehicle, and sides flexibly connected to panels alongside the engine, and a rearward end mounted to the utility vehicle with a pair of suspension members.
