  • Reduced wind resistant haulage vehicle apparatus
    Patent number: 7694774
    Abstract: A reduced wind resistance haulage vehicle apparatus includes an undercarriage portion which supports a motor/transmission. Driven wheel assemblies are connected to the undercarriage portion and are powered by the motor/transmission. A cab portion is supported by the an undercarriage portion for controlling the motor/transmission. Steering wheel assemblies are supported by the undercarriage portion for steering by a driver seated in the cab portion. A haulage portion is supported by the undercarriage portion. More specifically, the haulage portion includes haulage compartment side walls. Haulage compartment front doors and rear doors are connected to the haulage compartment side walls. When the haulage portion is empty, the front doors and the rear doors are opened, and air flow can flow through the haulage portion when the vehicle is driven along a road surface. As a result, the air resistance of the vehicle is significantly reduced, and the vehicle saves in energy demand and in fuel consumption.
