Patent attributes
A vehicle can be designed using modular frame components. There is provided a chain tank module having one or more chain tanks and an adapter module which provides spacing between individual chain tank modules. Wheels are mounted to the chain tank modules. The chain tank modules have wheel cogs to receive drive chains and also receptacles for receiving axles for the wheel hubs. The frame allows the use of steerable or nonsteerable axle assemblies to accommodate a wide variety of steering mechanisms for vehicles. By utilizing the chain tank and adapter modules, frames of different lengths, widths and wheel configurations can be designed and constructed using a small number of standard interchangeable parts. The cab and engine components are mounted onto a skid which in turn is mounted onto the frame. Drive chains are utilized to rotate the wheels. The drive chains extend through the chain tanks which contain a lubricant therein.
