Description

Wheel inertia engine and power generation device

technical field

The utility model relates to a wheel inertia starting and power generation device, which is applied to a vehicle that uses tires to move, especially a power generation principle that uses magnetic flux changes, and is matched with more than one set of permanent magnets, more than one set of induction coils and a Wheel inertia starting and power generation device of super capacitor. the

Background technique

According to the research report of the International Energy Agency (IEA), carbon dioxide emissions in 2005 were 27.6 billion tons, of which, power generation based on fossil energy accounted for 46% of the total emissions, and transportation based on fossil energy Emissions from tools account for 23% of total emissions, so carbon dioxide generated by power generation and vehicles is one of the main sources of carbon dioxide emissions. Currently, existing vehicles use fossil energy directly or indirectly, such as direct use of petrochemical energy. Automobiles and locomotives with energy as the power source, or vehicles that indirectly use petrochemical energy, such as the battery of an electric vehicle needs to obtain electric energy through the grid for charging, in order to drive the electric motor (motor) of the electric vehicle to work. Furthermore, pneumatic power Although the car uses compressed air as fuel, the compressed air still needs to be powered by the grid, so that the motor drives the air compression pump, and then the air can be compressed and sent to the gas storage bottle of the pneumatic car to drive the air motor of the pneumatic car to work. The same is true for oil-powered vehicles, because the oil-pressure cycle needs petrochemical energy to drive related devices to make the hydraulic motor work. Moreover, the hydrogen-powered vehicles advertised as 100% environmentally friendly must also be driven by petrochemical cracking or electrolysis. Obtaining, the above-mentioned acquisition methods all use fossil energy in a direct or indirect way. Even if the power vehicle advertised as not using fossil energy, it only transfers the pollution of carbon dioxide emission to the power plant that uses fossil energy to generate electricity. the

In the automobile industry, no matter what kind of fuel energy is used, it is necessary to consider the reusability of energy, safety, conversion efficiency, cost-effectiveness and accurate calculation of fuel residuals. Therefore, traditional power vehicles that directly or indirectly use fossil energy has its disadvantages:

1. Diesel and gasoline-powered vehicles directly use petrochemical energy, and convert 100% of the petrochemical energy into 35% of the chemical energy of the petrochemical energy through the work of the internal combustion engine through the procedures of intake, pressure, explosion, and exhaust of the internal combustion engine. , 30% of the engine cooling energy and 35% of the mechanical energy, but due to the idling of the vehicle and the loss of improper oil-gas ratio, the actual mechanical energy used to drive the vehicle is less than 20%. Part of the petrochemical energy emits harmful greenhouse gases. Even if the vehicle is equipped with a thermoelectric recovery unit to recover the heat of the engine and the heat of the exhaust gas, the efficiency can only be increased by 5%. Moreover, diesel and gasoline are disposable energy sources. Therefore, it is necessary to generally set up gas stations so as to supplement energy sources, so the battery life of diesel and gasoline-powered vehicles is obviously insufficient. the

2. The gasoline-electric hybrid vehicle is a transitional product to improve the battery life of the power vehicle. It has two different power supply units of internal combustion engine and electric motor or generator, and the two power sources can complement each other to reduce the pollution caused. And increase the battery life, but the price of the gasoline-electric hybrid is expensive, and its structure is precise, so it is quite troublesome to maintain. the

3. The electric vehicle uses electric energy to drive the electric motor or motor to work, so that the power vehicle can start, accelerate and other movements. When the vehicle brakes, it uses the braking power to regenerate the mechanical energy to convert the electric motor into a generator, and recharge the power to the battery. , but the electric vehicle cannot accurately calculate the residual power, and the charging time of the existing battery structure is too low in ampere-hours, and the cost of the battery to improve the battery life is relatively high. In addition, the power of the battery of the electric vehicle comes from fossil fuels and is disposable It is necessary to generally set up power stations to supplement energy. the

4. Pneumatic powered vehicles, compressed air is a kind of clean energy, using high-pressure air to drive the piston to reciprocate, and then drive the crankshaft to rotate, so as to simulate the engine working procedures of general petrochemical energy powered vehicles, and drive the pneumatic powered vehicles to move forward and accelerate etc., but air is only the medium of energy, and the power for air compression is the electric motor of the compressor, which needs to use electricity as energy, and the source of electricity comes from a power plant, so it only transfers the pollution generated to the power plant. the

5. Hydraulic power vehicles use internal combustion engines or electric motors to drive hydraulic oil to generate high pressure, and then push the hydraulic motor to rotate to generate mechanical energy to move the vehicle forward. The use of internal combustion engines or electric motors to generate high pressure for hydraulic oil is still a direct or indirect use. petrochemical energy. the

6. Hydrogen internal combustion engines or fuel cell powered vehicles use hydrogen fuel as a power source, introduce hydrogen fuel into the internal combustion engine for chemical action or use hydrogen fuel as the energy source of the fuel cell to make the fuel cell generate electricity, although the above does not mention the use of The stage of petrochemical energy, but hydrogen fuel needs to be produced by means of refining or waste gas recovery of by-products of the petrochemical industry or electrolysis of hydropower, so the resources consumed and the cost are relatively increased. the

The mechanism of the traditional electric motor (motor) and the generator is 100% the same, but they can only complete single-function starting or generating operations, although as No. 3,913,004 of U.S. Patent No. 3,913,004 discloses a kind of generator generator that can generate electricity or start The device uses one or two sets of generators to connect in series and parallel to achieve the application of starting and generating electricity. However, due to the structural limitations of traditional brushed motors, the volume, size and weight cannot reach the requirements of the automotive industry. Demand; again, as No. 4,441,043 of U.S. Patent No. 4441043, a kind of brushed motor concept of double magnetic flux air gap disclosed, its utility model purpose uses radial-axial as starting source, to produce large power, but it does not have Under the condition of fast battery charge and discharge, the structure of double flux air gap cannot be effectively applied to the motor machinery. the

Whether using petrochemical energy or other power sources as fuel for power vehicles, there are issues of endurance and how to reduce pollution. Therefore, there is an urgent need for an autonomous energy concept car, which is expected to solve the current problems of power vehicles. question. the

Please refer to Figure 2, as shown in the figure is a schematic diagram of the implementation of the utility model, and please refer to Figure 1; it is explained in the mode of radial start and axial power generation. When the four wheels of the power vehicle are working at the same time, the smart grid circuit of the vehicle The radial state management unit 12 is selected to be in the starting state, and the axial state management unit 11 is selected to be in the power generation state.
