Filed: 1994-11-21
Abstract: PURPOSE:To promote the extent of economy in energy consumption by absorbing an amount of kinetic energy to be discharged at a time when an automobile and other cars are decelerated or stopped through a power spring, and discharging the energy stored in the spring for the end. CONSTITUTION:When an accelerator is operated, such a force that a power spring is released is transmitted to a shaft 2 transmitting a rotation to a wheel from a shaft 1 of this spring, and likewise when a brake is operated, reversely this force is transmitted to a direction of winding the spring of the shaft 1 by a rotation of the shaft 2 imparting it rotation to the wheel. At the time of being not acclerated or declerated, the shaft 2 transmitting the rotation to the spring shaft 1 and the wheel is made to come off, merely traveling by the force of inertia. Therefore, the lowering of production cost in an automobile and its selling price and a reduction in manintenance cost including gasoline charge or the like are all promotable.
