Abstract

The present invention relates to an electric vehicle drive apparatus using hydraulic pressure. The electric vehicle drive apparatus using hydraulic pressure uses at least two hydraulic pumps. According to the present invention, fine dust and carbon emission can be reduced by driving a large-sized vehicle using diesel by using hydraulic pressure of an electric vehicle.

Description

유압을 이용한 전기 자동차 구동장치{Electro-hydraulic drive system}[0001] Electro-hydraulic drive system [0002]

전기 자동차Electric car

산업용 유압기기      Industrial hydraulic equipment

대형 자동차나 화물 운송용 자동차와 같이 차량의 무게가 무거운 차량은 출발 구동시나 주행시 강한 힘과 빠른 회전력이 요구된다. A vehicle having a heavy weight such as a large car or a freight car requires a strong force and a high torque when starting or driving.

유압으로 작동되는 모터를 사용하여 압력으로 인하여 힘을 유량으로 인하여 속도를 제어하도록 함으로 힘과 속도를 차량이 출발시나 가속에서도 충분한 능력으로 구동하도록 하였다By using a hydraulically operated motor, the pressure is controlled by the flow rate of the force, so that the power and speed are driven by the vehicle with sufficient capacity at the start and acceleration

경유 자동차와 같이 대형 차량의 전기 자동차로 함으로 미세 먼지나 탄소 배출을 줄일수있다.        As an electric vehicle of a large vehicle such as diesel vehicles, it is possible to reduce fine dust and carbon emissions.

1, 유압 모터를 변속기 입력 측에 연결하고 유압 모터의 토출구를 오일 저장 탱크에 연결하며 연결 관로에서 저항이 생기지 않 토 록 한다. 2, 유압 모터 유입구에 체크 벨 브 를 설치하여 유압 모터에서 필요한 오일 량 보다 작게 공급될 때 오일 저장 탱크에서 유입되도록 한다. 3, 유압 모터 유입구에 관로를 연결하고 유압 펌프 토출구와 연결하며 각각의 펌프 토출구에 무 부하 벨 브 를 설치하여 설정된 압력이 되면 펌프가 무 부하로 회전하게 하며 무 부하 회전시 생산된 오일이 탱크로 흐르게 하며 다른 펌프에서 생산된 오일이 탱크로 유입되지 못하도록 체크 벨 브를 부착한다. 4, 각기 다른 전기 모터를 설치하며 하나의 전기 모터에 유압 펌프 3개를 병렬로 연결하고 오일 압력에 의하여 순차적으로 오일을 생산하게 한다. 5, 전기 모터를 배터리에 연결하고 컨 트 럴 러로 속도를 조절하도록 액 셀레 터를 연결하되 1번 2번 2개의 전기 모터를 동시에 컨 트 럴 하여 높은 압력과 많은 양의 오일이 필요할 때는 2개의 전기 모터가 동시에, 적고 높은 압력이 필요할 때는 1번 펌프만, 회전하도록 한다.1, connect the hydraulic motor to the transmission input side, connect the discharge port of the hydraulic motor to the oil storage tank, and prevent the resistance from occurring in the connection line. 2, Install the check valve at the hydraulic motor inlet so that it will flow from the oil storage tank when supplied less than the required amount of oil in the hydraulic motor. 3, Connect the pipeline to the hydraulic motor inlet, connect to the hydraulic pump outlet, and install a no-load valve on each pump outlet. When the pressure is set, the pump will rotate without load. And check valves to prevent oil from other pumps from entering the tank. 4, different electric motors are installed, three hydraulic pumps are connected in parallel to one electric motor, and oil is produced sequentially by oil pressure. 5, connect the electric motor to the battery and connect the accelerator to control the speed with the controller, but control the 1, 2 and 2 electric motors at the same time. If you need high pressure and high amount of oil, If the motor needs to be low at the same time, and only high pressure is needed, only pump # 1 should be rotated.
