Abstract
Description
[0001] The invention belongs to the field of oil and electricity driven automobiles, and in particular relates to a self-increasing range and long driving time system for automobiles. Background Art
[0002] Today's automotive powertrains are classified into gasoline, full electric, and hybrid. Gasoline technology is mature, but it has a significant environmental impact. Full electric power offers low cost, low energy consumption, and environmental benefits, but suffers from poor range. Hybrids have their advantages and disadvantages, and while improvements are expected with scientific advancements, they are likely to be time-consuming, costly, and technically challenging. Summary of the Invention
[0003] The purpose of the present invention is to improve the existing automobile power drive mode, provide an automobile self-extending long driving time system, and solve the problems existing in the above-mentioned prior art.
[0004] The technical solutions of the present invention are as follows:
[0005] A vehicle self-range extension and long driving time system is characterized in that the vehicle self-range extension and long driving time system is set to a front-wheel drive in the front and a high-power wheel drum motor is installed in the rear drive. When powered on, it is a driving wheel, and when powered off, it is a driven wheel. The rotor is installed on the transverse axis, and the stator is added to the outer shell to form a generator. The wheel drum motor drive is required to switch to four-wheel drive. When the vehicle is driving, the transverse axis rotates, the generator generates electricity, and charges the battery pack. The battery pack is divided into two groups AB. Group A is charged and group B is supplied with power. When group B reaches the critical point of depletion of power, the charging is switched to group B and group A is supplied with power. The power of battery group AB is set by a comprehensive estimate of the charging (supply) time and mileage. The driven wheel generator group can be equipped with a speed change system, which accelerates at low speeds and maintains a constant relative speed number, which is conducive to charging. The vehicle self-range extension and long driving time system described in the present invention reduces energy consumption and increases driving range.
[0006] When a car is moving, the heat energy of oil or electricity is converted into mechanical kinetic energy, driving the vehicle. The principle of a generator is to generate electricity through the action of a rotor and a stator. Oil or electricity, while powerful in themselves, require minimal power to rotate. While driven wheel axle generators add weight, they utilize the vehicle's movement to generate electricity for charging the battery, requiring less power. The more driven wheel motors a truck has, the faster charging time, the longer the range, and the lower the cost. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] Figure 1 Structural diagram of the automobile self-extending long-distance driving system of the present invention DETAILED DESCRIPTION
[0008] A vehicle self-extending range long driving time system is based on a hybrid plug-in full electric vehicle, with two battery packs added, AB group 6. When the vehicle is started, the generator 1 generates electricity, charges the battery 6, and the vehicle is driven by the battery. The invention installs a wheel drum motor 10 on the rear wheel, which belongs to the four-wheel drive system. When the vehicle needs four-wheel drive, it is powered on and driven. When it is not needed, it becomes a driven wheel. The invention installs a rotor on the driven wheel axle and a stator on the outer shell to form a driven wheel (rear wheel) axle generator 11. When the car is running, the speed is changed by the 9 speed gears at low speed, and the axle generator 11 generates electricity and charges one group 6. At this time, the engine is turned off and the full electric drive is switched to power group A and charge group B. When the power consumption of group A approaches the critical point, the battery of group B is switched to power, and the battery of group A is charged, and so on.
