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 side-by-side vehicle is disclosed. The vehicle may include a rear, independent trailing arm suspension system and a drive train. The drive train may include an output from a power train coupled to a jack shaft to drive the vehicle. The jack shaft may be positioned entirely below the power train. A brake and sprocket may be positioned along the jack shaft. Additionally, the power train may be adjustably mounted to a frame of the vehicle.

Described are devices, systems, and methods that enable greater control and customization of variable suspension systems via mechanical modification, among other advantages. In one example, a linkage device is configured to be attached to a suspension arm of a vehicle and to a vehicle frame of the vehicle. The linkage device is configured to mechanically modify one or more physical states detected by a sensor of the vehicle, thereby causing the sensor to output modified signals to a controller, and causing the controller to output modified control signals to a variable shock absorber connected between the vehicle frame and the suspension arm, thereby modifying one or more variable physical properties of the variable shock absorber.

A utility vehicle with ergonomic, safety, and maintenance features is disclosed. A vehicle is also disclosed with improved cooling, suspension and drive systems. These features enhance the utility of the vehicle.

An off-road vehicle has a frame, a motor, a steering input device, a storage bin disposed forward of the steering input device, the storage bin having side walls and a bottom wall, and an accessory holder assembly connected to the storage bin. The accessory holder assembly includes a receptacle having an upwardly facing receptacle aperture for receiving an accessory. The receptacle aperture is disposed within a perimeter defined by the side walls of the storage bin. The receptacle extends below the bottom wall of the storage bin. A height of a portion of the receptacle extending below the bottom wall of the storage bin being greater than a width of the receptacle aperture and greater than a length of the receptacle aperture.

Some embodiments of the disclosure are directed to vehicular retrieval, transportation, and/or deposition of payloads. In some embodiments, a vehicle is configured to identify and approach, via a plurality of propulsion components, a respective payload. In some embodiments, the vehicle is configured to adjust a height of a chassis of the vehicle, via the plurality of control legs, with respect to a reference to position interior portions of the chassis around a surface of the respective payload. In some embodiments, the vehicle is configured to engage with, via a latching system, the respective payload. In some embodiments, the vehicle is configured to transport the respective payload, via the plurality of propulsion components, to a respective target location. In some embodiments, the vehicle is configured to disengage from the respective payload, via the latching system, to deposit the respective payload at the respective target location.

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.

Disclosed is a self-balancing device for self-propelled off-road RV box body. The self-balancing device includes an auxiliary beam body for connecting with a bottom end of the RV box body, a front triangular balance beam body, a rear triangular balance beam body and an axle-holding device for connecting with a RV chassis girder. The front triangular balance beam body and the rear triangular balance beam body are arranged close to both ends of the auxiliary beam body respectively. The axle-holding device is arranged between the front triangular balance beam body and the rear triangular balance beam body. Both the front triangular balance beam body and the rear triangular balance beam body include a hard limit structure for limiting a swing angle of the RV box body. The axle-holding device includes a soft limit structure for horizontally resetting the RV box body.

A vehicle includes wheels, suspension links, a torsion bar, and electronically controlled dampers. The suspension links support the wheels. The torsion bar generates a force to resist a tilting of the vehicle in the body roll direction. The electronic control dampers connect the torsion bar to the suspension links. At least a portion of each suspension links is located in front of the corresponding electronically controlled damper.
