Description

Three-in-one power system for vehicles

The creation of the present invention relates to the expansion of general vehicles with multiple powers. When the vehicle starts and runs at low speed, it uses pure electric motor power, and then uses electric power and diesel engine power to drive the vehicle. When driving at high speed, it switches to diesel power. The multi-purpose power design can greatly reduce pollution emissions and improve the performance of hybrid electric power.

It is generally known that the diesel engine is the main power source of heavy-duty vehicles. When the vehicle starts and runs at low speed, the combustion efficiency of the diesel engine is the worst and the pollution is the highest. Conversely, diesel engines have good combustion efficiency and low fuel consumption when driving at high speeds.

In order to overcome the foregoing problems, an electric motor is connected in series behind the engine, which is a known hybrid electric system. In the gasoline-electric hybrid system, the role of the electric motor is to output power to the auxiliary engine, and the output is intermittent. When the motor outputs power, the engine either outputs power synchronously with the motor, or runs at an idle speed. For heavy-duty trucks and refrigerated vehicles, the engine must drive auxiliary power to provide air conditioning, braking and steering power requirements.

Main purpose of the creation of the present invention:

1. Energy saving and carbon reduction, emission pollution reduction and noise reduction.

2. The three-in-one power source provides three driving modes in response to the needs of terrain, ground objects, and regions.

3. Increase the second auxiliary power system to improve driving safety mode.

Fig. 1 is a design schematic diagram of the creation of the present invention.

Fig. 2 is a design schematic diagram of the creation of the present invention.

As shown in Figure [1], the first power of the engine [1] is the single power source of conventional fuel vehicles, and the main power output is used to drive the transmission system [4] of the chassis to drive the vehicle. The engine power also needs to provide the auxiliary equipment of the vehicle, such as the steering oil pump, brake air compressor and air-conditioning compressor, or the power required by the refrigerated (storage) compartment, which is called the first auxiliary power[70]. If the first power of the engine stops running, the air compressor will also stop supplying air, and the pressure of the brake cylinder will drop; the oil pressure power required by the power steering will also lose power; the air conditioner, or the refrigerated (frozen) compartment will also stop. Among them, the braking and steering functions are related to driving safety and cannot be ignored. For heavy-duty trucks, even if they have conventional gasoline-electric hybrid systems, they cannot stop the power of the engine. Relatively, they cannot solve the problems of energy consumption and pollution emissions.

According to the invention, the vehicle carrier is designed with a three-in-one power output, (1) the power output of the fully silent pure electric motor (the engine is turned off), (2) the output of the electric motor and the engine at the same time, the power of the whole vehicle can be increased by more than 150%, ( 3) Engine power output (the motor is changed to generate electricity, or no power at all).

The power cascading method, as shown in Figure [1], the vehicle engine is the first power [1], which is combined with the vehicle’s second power [2] through the cascading mechanism [3]. The second power can be an electric motor. The tandem mechanism [3] can be a clutch, or a synchronizer, with a disengagement/combination mechanism inside. When the serial mechanism is combined, the first power and the second power are synchronously output power to the transmission system [4]. At this time, the first energy storage battery [5] is generally a 12V or 24V system, and the generator connected in parallel with the first power of the engine provides charging power. lead Engine the first power, and provide the first auxiliary power [70] power. The second power [2] receives the electric energy of the second energy storage battery [6], which is generally above 300V, and outputs the running power; or, converts part of the torque power of the first power into electricity, and stores and charges it to the second storage battery. battery. The electric energy converter [61] is an energy conversion unit between the second energy storage battery and the second power.

When the tandem mechanism is disengaged, refer to [Fig. 2], the engine power is separated from the second power, the second power completely replaces the engine power, and the power source of the vehicle is only the second power. At this time, the second energy storage battery outputs electric energy to the second power. The first power of the engine after separation, in order to reduce pollution and fuel consumption, the first power turns off and stops running. At this time, the peripheral devices of the vehicle, such as air conditioners, brakes and steering mechanisms, must immediately switch to a power source with stable output because the first energy storage battery cannot supply power for a long time, and considering driving safety and reliability.

The present invention also provides at least one set of third power motor [7] to provide the second secondary power [80] required by the steering oil pump, brake air compressor and air conditioner compressor with gears or pulleys. The second energy storage battery, through the electric energy converter [62], provides the stable electric energy required by the third power motor.

When the first power of the engine is temporarily stopped, in addition to using the third power motor mode, or at least one set of transformers can be connected in series and parallel to the second energy storage battery to directly provide electric energy to the steering oil pump, brake air compressor and air conditioning compressor The second auxiliary power required by the machine, etc.

According to the invention, the vehicle has a three-in-one driving power source, which can be driven by pure electric power in urban areas without noise and emission pollution; the third power is designed to support the second auxiliary power when the engine is turned off. , to provide a stable source of power for air conditioning, steering and braking. This design can recharge the power through the hybrid electric power to increase the battery life. The three-in-one power design can indeed achieve high-efficiency goals such as energy saving, carbon reduction, and low noise.
