All-terrain construction vehicles are provided that can include: a central frame; a pair of axles, each of the axles extending substantially normally across an axis of the central frame and pivoting in relation thereto; and at least two pairs of wheels. The vehicles can include at least two pairs of levelers. The vehicles can include out-rigging operatively extending above the one axis and between an operator cab and fluid pump unit in at least one configuration, the pump and fluid therefrom operatively coupled to the axles and wheels, the axles, wheels, and pump being operatively controlled via an operator interface within the operator cab. The vehicle can include levelers along the one side of the axis of the frame configured to support a utility pole above the hydraulic fluid pump unit.

A hydraulic drive unit for use in a vehicle or other application incorporates a motor disposed in a housing and connected to a pump through a porting system, and an output shaft driven by the motor. A mechanical brake is used to brake the motor, while a valve provides a hydraulic brake for preventing flow between the hydraulic motor and the hydraulic pump. A brake actuator is connected to both the mechanical brake and the hydraulic brake, whereby actuation of the brake actuator causes both the mechanical brake and the hydraulic brake to be actuated.

The present invention provides a system and method for economically using compressed air as automobile power source, comprising: a compressed air power device, which includes automobile air storage tubes (1) to store a sufficient amount of high-pressure compressed air and a cylinder-combined engine consisting of the first and second cylinders (9)(10), and which can make full use of the compressed air to produce driving power; a mechanism to produce, store and provide high-pressure compressed air, which includes a boiler-type high-pressure compressed air producing and storing device, abbreviated as boiler-type HCAPS device (4), to be able to use electricity during periods of low energy demand (off-peak) such as at night simultaneously recovering the by-produced heat for central heating, and pressurizing and inflating into the automobile air storage tubes (1) during daytimes; brake energy recovery and regeneration devices, which include a spring reserving-releasing device and/or a compressed air reserving-releasing device to save the compressed air in the automobile air storage tubes (1) for saving the driving power; an inner gear ring assembly, which includes an inner gear ring (2) gearing meshing with inner acting gears (45), with the first and second accelerating gears (72)(92), with a flywheel front inner meshing gear (48) and reset gears (46), for transmitting torque and mixing/outputting power; some clutch transmission devices and a controller, which controls orderly coordinated operation of devices and mechanisms.

A suspension automobile comprising an automobile body, wheels and a flow disturbing plate, the wheels connect the flow disturbing plate through connecting devices, and a fluid channel communicating with the outside is formed between the upper surface of the flow disturbing plate and a bottom shell of the automobile body; a power device used for driving the automobile is contained in the body and is suspended along with lift force generated by the body. The invention changes the common sense that the wheels bear all weight generated by the self-weight, loads, and gravitational acceleration of the automobiles when traveling; the body which exceeds 90% by weight of the automobile generates lift force to suspend, the wheels eliminate lift force; meanwhile, a novel propelling force source is found from fluid resistance; the suspension automobile can be driven by various energy including engines and clean energy, thus effectively reduce energy loss.
