Description

Battery charging apparatus for drining type of oil pressure used propeller shart of hybrid electric vehicle

The present invention automatically converts the power of the propeller shaft to the operating power of the generator when the vehicle is decelerated or stopped by operating a brake pedal while driving a road or a sloped road downhill of a propeller shaft flat of a hybrid electric vehicle. To charge the battery, and automatically charges the battery with the rotational power of the propeller shaft that rotates by the elastic force of the vehicle moving forward, even if the power of the engine and the electric motor, such as a downhill road, is not transmitted to the wheels. The present invention relates to a hydraulically driven battery charging device using a propeller shaft of a hybrid electric vehicle that can minimize the operating time of a separately installed small charging engine.

In general, a hybrid vehicle means a vehicle that uses two power sources, which are equipped with an internal combustion engine and an electric motor driven by a battery of an electric vehicle, reduce weight of the vehicle body and minimize air resistance. This is the next generation of cars that drastically reduced fuel consumption and harmful gas emissions compared to conventional vehicles. In addition, when there are many hybrid electric vehicles as described above, it is possible to reduce the harmful gas by more than 90% compared to the existing vehicles, improve the air and the surrounding environment of large cities, and also fit the traffic control and road planning, so that the environmental vehicles (eco Also called -car).

The hybrid electric vehicle as described above refers to a form in which an electric motor is coupled to an internal combustion engine used in an existing vehicle. The electric motor is powered from a high voltage battery mounted inside the vehicle, which is recharged when the vehicle is moving.

In addition, most of the energy loss of the existing vehicle occurs at idle time due to traffic congestion and when the vehicle stops. The hybrid system as described above compensates for the disadvantages of the gasoline or diesel engines, depending on the speed and driving conditions of the vehicle. Properly controlling the power of the motor maximizes efficiency.

The hybrid electric vehicle as described above starts the engine with an electric motor when starting first, and during normal driving or acceleration, the engine becomes a main power source and the motor operates as an auxiliary power source. When the brake is decelerated, the kinetic energy of the vehicle is converted into electrical energy to charge the battery. And when you stop the car, both the engine and the motor stop.

In addition, the engine power of the vehicle as described above is transmitted to the axle by the propeller shaft and run through the transmission. When explaining the propeller shaft of the vehicle in more detail, the propeller shaft is connected to the transmission and the differential to transfer the driving force of the transmission, that is, the power of the engine to the wheel (wheel) through the differential, such a propeller shaft Both ends of the universal joint is installed so that the driving force can be transmitted smoothly.

As described above, the vehicle operates the brake pedal when the vehicle speeds down or stops while driving on a flat road and a downhill road. In addition, when the brake pedal is operated as described above, the vehicle is driven forward by the elastic force that has been driven, and the propeller shaft continues to rotate by the elasticity of the vehicle driven forward.

On the other hand, the hybrid electric vehicle as described above stops the engine at the time of starting and light load, and runs with the electric motor with only the power from the battery. In normal driving, the engine is driven by the direct drive and the motor driving using the electric power generated by the generator. When a large amount of power is required such as acceleration, overtaking, and uphill driving, power is supplied from the battery in addition to the normal driving. When the deceleration is increased, the electric motor is converted into a generator to generate deceleration energy and recharged by recharging the battery.

However, the conventional hybrid electric vehicle as described above has a problem in that the charging time is shortened by charging the battery only when the brake pedal is operated and the deceleration time is short, and the use time of the battery is also shortened.
