PROBLEM TO BE SOLVED: To provide the car driving unit which does not generate the exhaust gas to improve the control performance while holding the resources by raising the energy efficiency vastly by changing the power of the conventional internal combustion engine to an electric drive along with the depletion of fossil type energy resources. SOLUTION: In order to improve the control performance by converting the electric energy into the liquid pressure energy, the flow of an electric motor driven hydraulic pump is supplied for the running operation by controlling a flow dividing valve. Furthermore, it makes a convertible drive unit which can change the speed continuously. And the charge of the electric power is attained by an alternator. COPYRIGHT: (C)2009,JPO&INPIT |
