height decrease 64 of any vehicle upon which the axle is mounted this provides easier access onto a vehicle which is especially helpful to handicapped and older people it also lowers a vehicle to pass under a low overpass fig5 amp 6 a front view of fig5 show a further embodiment of the invention round shaped wheel pulley 70 is rotated counterclockwise by drive 72 conventionally circular shaped wheel pulley 74 is in no contact 78 with rotating wheel pulley 70 and is therefore stationary as the normally round shaped wheel pulley 74 is reforming to vertical oval shape wheel pulley 76 contact is made between round shaped wheel pulley 70 and vertical oval shaped wheel pulley 76 at point 79 rotational power of pulley 70 is transmitted at point of contact 79 providing clockwise rotational power to shaft 80 upon changing vertical oval shaped wheel pulley 76 back to its original conventionally circular shaped wheel pulley 74 disengagement of rotational motion of shaft 80 occurs as can be shown upon change in shape of circular to oval and back to circular a simple transmission of power from one drive to another results this is also accomplished by change of the common circular pulley form to elliptical and any other form differing from the common circular the wheel pulley can also be of other patterns such as gears and the like this simple power transmission can be used for application on vehicles of all types industrial power machinery tools any machinery requiring engagement and disengagement of rotational power fig7 shows the large area of contact 86 for power transmission between two wheels where the large contact area provides large rotational power transfer from one to another normal contact for power transfer between conventional.
