<p>PURPOSE:To aim at shortening a charging time to an auxiliary battery serving as a power source for various apparatuses used in a campsite and the like. CONSTITUTION:This driving device is provided with a main charging system consisting of a hydraulic pump 10, a hydraulic motor 16, a main alternator 22 and a main battery 24, and an auxiliary charging system consisting of a hydraulic pump 11, a hydraulic motor 17, an auxiliary alternator 23 and an auxiliary battery 25 respectively. In this constitution, it is so constituted to drive both these hydraulic pumps 16 and 17 at constant revolution by means of oil to be discharged out of these hydraulic pumps 10 and 11 made up of being flow-controlled so as to become a fixed flow rate at more than the idling speed irrespective of engine speed, so that even if idling frequency is so high in an actual traveling state, sufficient generating energy is made so as to be secured, and a promotion of shortening a span of charging time to the auxiliary battery 25 is contrived, whereby capacity of this battery 25 is made so as to be largely settable.</p> |
