This disclosure is an auxiliary system to provide additional power for vehicles which can be applied to land wheel type vehicles without depending on rails, to convert most of the front-wheels drive and rear-wheel drive vehicles to multi-power all-wheel drive vehicles with low cost, the multi-power comprises but not limited to various fuels such as oil, gas, electricity, hydrogen fuel and various other fuels.
At present, the most basic classification standard adopted by the vehicle is according to the number of the driving wheels, and can be divided into two-wheel drive and four-wheel drive. In the two-wheel drive type, the advantages of a rear-wheel drive are as follows: (i) of being good in controllability, (ii) good performance in starting stage and acceleration and comfortable during above processes, (iii) maintenance is easy. The disadvantages of a rear-wheel drive are as follows: (i) relatively higher cost and the space utilization are less convenient, (ii) the fraction force is insufficient and often over turns for a vehicle, (iii) and higher power loss. The advantages of a front-wheel drive are as follows: (1) lower manufacturing cost and high power efficiency, (ii) lighter vehicle weight, (iii) increase interior cabin space. The disadvantages of a front-wheel drive are as follows: poor controllability, (ii) insufficient vehicle turns, (iii) too much load on the front axle so the comfort level decreased. All-wheel drive refers to that the front wheel and the rear wheel of the vehicle are all powered, and the output torque of the engine can be distributed on all the wheels and the output torque can be applied to different wheels in different proportions according to road conditions so as to improve the performance of vehicle.
The current gas-electricity hybrid electric vehicle has good fuel economy performance and excellent in driving performance. The engine of the hybrid electric vehicle uses gas and fuel economy performance is good because of the electric motor during starting stage and acceleration, In short, the fuel consumption of a hybrid electric vehicle is lower than that of the vehicle with the same size. The power system of the hybrid electric vehicle is mainly composed of a control system, a driving system, an auxiliary power system, a battery pack and the like.
This disclosure provides an auxiliary system to provide additional power for vehicles which can be additionally arranged on most land wheel type vehicles without depending on rails.
However, a single power system vehicle just coming out of a factory is NOT equipped with this technical convenience which waste energy. The two-wheel driving type vehicles cannot solve the problems when the vehicle power is insufficient during the starting stage or climbing where too much loading of the engine occurs.
The technical scheme adopted by this disclosure is adding one to a plurality of motors which are additionally arranged on a non-drive shaft and controlled by the controlled box according to the single-chip microcomputer in the control box to decide whether to apply the auxiliary power according to preset commands, the status and speed of the vehicle, and signals transmitted by the brakes and a gas pedal of the vehicle. The energy of the system is supplied by the independent rechargeable battery pack which can be charged by utilizing the kinetic energy of the vehicle when the vehicle is running by kinetic energy or by gas, or is braking to slow down.
According to above technical scheme, a more specific technical scheme can also be that one to a plurality of motor devices are arranged on an existing non-transmission wheel. The motor can rotate the shaft so that the vehicle becomes an all-wheel drive vehicle when the vehicle is operated at a low speed. When the gas pedal is stepped, the motor rotates and provide energy to move the vehicle. The motor works when the vehicle moves at a low speed. The disclosure does not require modifying an engine, a transmission, braking devices, steering devices and refrigerating devices, so that most of the front-wheel drive and rear-wheel drive vehicles can be modified into a multi-power hybrid vehicle at extremely low cost.
The electric motor outputs power while the vehicle moves at a low speed and the electric motor becomes an electrical generator to charge the rechargeable battery pack when vehicle moves at a high speed. When the vehicle speed is higher than a certain preset speed per hour, the preset speed is adjustable, such as 40 kilometers or 60 kilometers per hour, the motor becomes a generator, so that the kinetic energy can be converted into electrical energy and stored in the rechargeable battery pack. When the vehicle is braking to slow down, the motor can also be used as a generator to charge the rechargeable battery pack. The preset speed for the motor to switch to the generator is adjustable.
Due to the adoption of the above technical scheme and to compare with the prior art, the advantages of this disclosure are of being capable to widely install on existing gas vehicles to provide auxiliary power without changing the current vehicles' systems, and the modification cost is low while modification can be completed by merely three steps.
1. Arranging this disclosure on a non-driving wheel shaft.
2. Connecting the control box with the brakes, a gas pedal and the dashboard.
3. Placing the rechargeable battery packs to the spare position of the vehicle.
