Abstract

An electric vehicle driving system includes an energy-storage apparatus (), a first motor (), a speed regulating motor () and a single row planetary mechanism. Said first motor () and said speed regulating motor () are connected electrically to the energy-storage apparatus (). The single row planetary mechanism includes a sun gear (), a gear ring () and a planetary carries () with planetary gears (). The planetary gears () in the planetary carrier () mesh the gear ring () and the sun gear () separately. The output axle of the first motor () is connected to the gear ring (), and the output axle of the speed regulating motor () is connected to the sun gear () by a brake (). The invention takes the speed regulating motor and the single row planetary mechanism instead of the gearbox in a transmission driving system, and achieves a simple and compact structure, easy assemble, light weight, and low manufacturing cost. With the speed regulation of the speed regulating motor, the first motor works in high efficiency speed range, which increases energy utilization rate and endurance mileage.
