    摘要: To provide a control system of blowing means for construction machines that enables to prevent the loss of battery charging amount even if an engine rotation speed is low and an alternator generates less electricity. A control system 2 of blowing means for construction machines comprises a heat exchanging means, a blowing means for blowing air to the heat exchanging means, an electric driving means for driving the blowing means, a temperature detecting means for detecting temperature of fluids running through the heat exchanging means, an alternator 4 generating electricity by being driven by an engine 34, and a control means for determining an upper limit rotation speed of the electric driving means based on current generated by the alternator 4 and controlling a rotation speed of the electric driving means based on temperature detected by the temperature detecting means while the rotation speed is below the upper limit rotation speed.

    摘要: A drive arrangement for a least one auxiliary equipment of a hybrid vehicle includes a gearbox having at least one input shaft connected to a drive internal combustion engine and one output shaft connected to driven wheels of the vehicle. The drive arrangement includes a power split device having no more than three separate input/output couplings, with a first coupling connected to the input shaft, a second coupling connected to the output shaft, and a third coupling connected to the at least one auxiliary equipment. The drive arrangement includes an auxiliary electric machine connected to one of the couplings of the power split device, and adapted to deliver torque to the at least one auxiliary equipment. The drive arrangement further includes an arrangement to disconnect the first coupling from the input shaft of the gearbox.
