An electric vehicle ( 1 ) includes a charging circuit ( 11 ), a battery ( 12 ) and a driving electric motor ( 13 ), and an air compressor ( 14 ), an air storage tank ( 15 ), a turbine ( 16 ) and a generator ( 17 ). Air is compressed and stored in the air storage tank when the air compressor starts up. The air storage tank is provided with a switch valve, and under the control of the switch valve the air stored in the air storage tank is fed to the turbine. By means of providing an air compressor, an air storage tank, a turbine and a generator, and using air energy to generate power and using the battery to supply power in parallel, the continuous mileage of the electric vehicle is increased. In addition, the service life of the battery is prolonged, because the battery is used in a low depth of charge/low depth of discharge manner.

Method for controlling the power of a forestry machine

Opposing pump/motors

Two motors are arranged on opposing sides of a common shaft, drive plates of the pump/motors being rigidly coupled to each other, for example by being in hard contact with opposing sides of the shaft. By providing hard contact between the pump/motor drive plates and a common shaft, the drive plates and shaft act as a substantially solid element under compression, thereby substantially canceling axial loads generated by the pump/motors directly through the shaft. Residual axial loads are handled via bearings positioned on the shaft adjacent the drive plates in such a manner that the drive plates are in light contact only with the bearings. As a result, friction experienced by the bearings is substantially reduced as compared to conventional systems, thereby improving the efficiency of the system. To further reduce loads on the bearings, the pump/motors are arranged to ensure that they generate radial forces in a direction that is opposite to that of a separation force generated by a torque transferring device carried on the shaft and transmitted to the bearings. A common housing surrounding the two pump/motors, bearings and torque transferring device is divided into three regions, to segregate the bearings and torque transferring assembly from the pump/motors. In this manner, the regions containing the pump/motors are substantially filled with oil to, for example, fully lubricate the pump/motors, while the central region containing the gears and torque transferring device contains a significantly smaller volume of oil to simply splash lubricate the contents of the region, thereby reducing drag on the bearings. Control means are provided for selectively moving the two pump/motors substantially simultaneously to a selected displacement angle, using mechanical systems alone and in combination with hydraulic systems.

The module includes a hydraulic motor configured to provide motive power at an output shaft, and a differential for distributing the motive power to right and left portions of the axle. The hydraulic motor and the differential are encased within a common housing. The vehicle may include a second integrated drive module having, within a housing, a second hydraulic motor (or multiple hydraulic motors), and a second differential coupled thereto and configured to distribute motive power to right and left portions of a second axle. The second module may also include a transmission within the same housing. The transmission may be a two speed or other multi-speed transmission. The second module is configured to operate in neutral while power demand is below a threshold, and to engage while the power demand exceeds the threshold. The second module may be configured to remain engaged for full-time four-wheel-drive operation.

Method for controlling a power source of a forestry machine

The present invention relates to a method for controlling a power source (1 , 10) of a forestry machine. This power source utilizes directly or indirectly one or more work devices and/or handling devices (3, 4, 7, 8) positioned in the forestry machine and controlled by a control means (2). When the control means in the forestry machine gives one or more work or handling devices a control command starting a change operation, it is transmitted substantially simultaneously to the power source. When arriving at the power source, one or more control commands requiring a power change of the power source affect control parameters of the power source, predicting the future load of the power source.
