HYBRID VEHICLE TRANSFORMATION WITH ELECTROMECHANICAL ENERGY

TRANSFORMED WHEELS

1. As a result of acceleration thanks to the fuel used, land vehicles with internal combustion engines release kinetic energy to the atmosphere in the form of heat energy through brake linings when they were stopped (braked). In order to accumulate and reuse this energy (released during braking) while starting the automobile, hybrid vehicles have been developed. Toyota Prius can be given as an example of those hybrid vehicles. It has won a number of prizes for its merits such as saving energy and decreasing environmental pollution. In hybrid vehicles, internal combustion engine (operating with fuel or diesel), electrical engine and an electromechanical energy transformation unit that can ruction as an electric generator are coupled on the same shaft. When the vehicle is braked or slowed down on its way down a slope, the vehicle's kinetic energy resulting from its speed and bulk is transferred to the electromechanical energy transformation unit in the form of mechanical energy through transfer units involving wheels, gear, bearing and rod. Electromechanical energy transformation unit functions as a generator and the electrical energy generated is stored in lithium-ion or Ni-MH power supply battery.

2. The electromechanical energy transformation unit is used as engine when the vehicle is started, thus the vehicle is accelarated in a very short period of time thanks to the aggregated power of the two engines (internal combustion engine and electrical engine). The fact that kinetic energy is accumulated during the brakings and that the idle running of the internal combustion engine is removed bring a significant amount of saving in terms of fuel consumption. Fuel consumption for the new generation Toyota Prius is given as 4,6 litres per 100 kilometres. These hybrid vehicles are highly environmental friendly due to their diminishing fuel consumption rates.

3. The new technology proposed with the invention of hybrid vehicle transformation with electromechanical energy transformed wheels shall function as a hybrid system in the way explained above for all the land vehicles including automobiles, minibuses, jeeps, trucks, vans, transporters and any type of heavy construction equipment with tyres, etc. without needing any significant changes in those vehicles' engine, gearbox, axle gear, electric and chassis electronic control, etc. systems. In order for this hybrid system to work on those vehicles, no significant change on the vehicle is required; only the size of the systems such as axle oil box, axle, brake drum to which the wheels are connected should be changed. Electromechanic energy transformed wheel unit which will be mounted together with these systems and function as both engine and generator, together with its rotating stator part, will constitute the πm of the vehicle's wheel or axle oil box on which the rim will be mounted. The electromechanic energy transformed wheel unit shall possess features provided by the state-of-the-art electrotechnic technology in terms of efficiency, cycle tuning and moment tuning. Technical features of the electromechanic energy transformation unit shall be determined and designed according to the wheel dimensions, the number of wheels and speed of the vehicle it will be mounted. This electromechanical energy transformed unit that will transform the vehicle into a hybπd one can be mounted on all the wheels or only on the back wheels or on the front wheels. The innovative aspect underlined here is that this electromechanical energy transformed unit can be mounted on any type of land vehicles (automobiles, trucks, buses, transporters, minibuses, jeeps, etc.) with internal combustion engines and tyres after they have been produced or while they have already been in use, thereby can "transform those vehicles into hybrid" ones. This system shall be composed of the following components: a) An electric power supply system involving lithium-ion or Ni-MH battery or high capacity condensers, b) An electronic power control unit for transforming the energy into the required voltage current and frequency and transforming the electrical energy (taken from the batteries during the start of the vehicle) into the electromechanic energy transformation unit which is employed as engine or for transforming the electrical energy (taken from the electromechanic energy transformation unit that is employed as the generator while the vehicle is braked or slowed down on its way down the slope) into the batteries after transforming this energy into the current and voltage required for the charging of the batteries, c) A micro-processing unit which process the data collected from all the sensors on the vehicle and perform all the processing steps that are attempted to be explained by a control software prepared.

4. The invention of hybrid vehicle transformation with electromechanic energy transformed wheels explained above shall provide the vehicles with high start power and enable significant amount of savings in fuel consumption. Further, with this invention, it will be possible to increase the level of handling of those 4x4 vehicles on slippery slopes thanks to a software addition to be made on the micro-processing unit. The systems used nowadays for contributing to the balance and handling of the vehicle such as ABS, ASR, etc. can also be added with the software addition and/or amendment. For braking, energy transformation will be used primarily and no balata or disc will be used or they will be used in smaller sizes only for emergency situations. Therefore, environmental pollution and damage caused by asbestos balatas which are still used on many vehicles today will be prevented. The kinetic energy transformation efficiency of the invention of hybrid vehicle transformation with electromechanic energy transformed wheels is higher than that of a classic hybrid vehicle due to the absence of gear transfer unit in this invention. Moreover, tore will be higher due to the big stator diameter of the electromechanic energy transformation unit. The possibility of controlling the revolution of each of the 4 wheels seperately with this invention will prove advantage in terms of traction and handling.

5. The most useful aspect of this invention of hybrid vehicle transformation with electromechanic energy transformed wheels is that it can be mounted on all the vehicles with internal combustion engines and tyres that have already been in use nowadays. In addition, it will enable a decrease in the energy consumption of those vehicles during their life-spans, improve their handling capacity and decrease the damage they will cause to the environment with their exhaust emissions.
