PURPOSE:To contrive to effectively utilize energy, by a method wherein a flywheel is provided in conjunction with the high-speed shaft side of a stepless speed-changing gear, the low-speed side can be connected to a vehicle propeller and the speed-changing gear is controlled in accordance with the operating condition of the vehicle. CONSTITUTION:In the propeller for rotating wheels 8 by an output torque of an engine 1 through a one-way clutch or centrifugal clutch 3, a driving gear 4, the stepless speed-changing gear 5, a propeller shaft 6 and a differential gear 7, a friction clutch 9 is provided coaxially on the driving shaft 4. When the clutch 9 is engaged, an energy-accumulating system consisting of a stepless speed-changing gear 12 and a flywheel 13 is connected to the propelling system through gears 10, 11. The speed-changing ratio of the gear 12 and the engagement and disengagement of the clutch 9 are controlled by a controller 16 in accordance with the operating condition, whereby energy at the time of braking is accumulated in the flywheel 13 so that it can be effectively utilized at the time of starting. |
