Description

차륜형장갑차용 전기식 구동시스템 {Electric Drive system for Wheel-type armored vehicle}Electric drive system for wheel-type armored vehicle}

본 발명은 차륜형장갑차용 전기식 구동시스템에 관련한 것으로, 특히 수소연료전지 또는 배터리 등의 전력 공급원에 의해 발생하는 전력으로 구동 모터를 작동하여 발생된 동력을 차동기어상자를 거쳐 타이어에 전달함으로써 수소연료전지, 전기 및 하이브리드 등의 전기식 차륜형장갑차에 필요한 동력을 제공하는 차륜형장갑차용 전기식 구동시스템에 관한 것이다.The present invention relates to an electric drive system for a wheeled armored vehicle. In particular, the power generated by operating the drive motor with power generated by a power source such as a hydrogen fuel cell or battery is transmitted to the tires through a differential gear box to generate hydrogen fuel. This relates to an electric drive system for wheeled armored vehicles that provides the power required for electric wheeled armored vehicles such as battery, electric, and hybrid.

일반적으로 차륜형장갑차는 차량 탑승원의 보호를 위한 경장갑이 적용되어 병력 수송이나 전투용으로 사용하는 군용 차량으로 보병 전투차(IFV)와 병력수송 장갑차(APC)가 대표적이며, 최근에는 예를 들어 자주대공포나 대공미사일 등 다양한 무장장치를 탑재하여 사용되는 경우가 많다. In general, wheeled armored vehicles are military vehicles equipped with light armor to protect vehicle occupants and used for troop transport or combat. Representative examples include infantry fighting vehicles (IFVs) and armored personnel carriers (APCs). Recently, for example, It is often used equipped with various weapons such as self-propelled anti-aircraft guns and anti-aircraft missiles.

종래의 내연기관 차륜형장갑차들은 생존성, 내구성 및 최고출력 등 성능을 우선시하여 배기가스 환경 규제 등에 큰 영향을 받지 않아왔다. 따라서 차륜형장갑차는 승무원의 생존성 확보를 위해 장갑 두께를 두껍게 하고, 다양한 임무 장비를 탑재하면서 무게가 증가되고 있고 이에 연관되어 고출력의 내연기관 적용이 지속적으로 요구되고 있다.Conventional internal combustion engine wheeled armored vehicles prioritize performance such as survivability, durability, and maximum output, and have not been greatly affected by environmental regulations on exhaust gases. Therefore, the weight of wheeled armored vehicles is increasing as the armor thickness is thickened to ensure crew survival, and various mission equipment is mounted. In relation to this, the application of high-output internal combustion engines is continuously required.

이에 따라, 차륜형장갑차 운용 시 내연기관 구동으로 인해 발생하는 과도한 소음으로 승무원의 피로도가 증가하고 소음 및 배기가스 등으로 주변의 많은 악영향을 미치고 있다.Accordingly, excessive noise generated by the internal combustion engine when operating a wheeled armored vehicle increases crew fatigue and has a negative impact on the surrounding area due to noise and exhaust gases.

이러한 상황에서 유럽 등 세계 각국에서 지속적으로 배기가스 배출량을 줄이기 위해 Euro7 등 현재 내연기관 기술에서는 만족할 수 없는 수준의 배출가스 규제를 강화하고 기업들의 ESG경영 등으로 친환경 차량의 개발을 요구받고 있다. 이에 따라 차량 제조사들도 친환경차량 개발에 역량을 쏟고 있다.In this situation, in order to continuously reduce exhaust gas emissions, countries around the world, including Europe, are strengthening exhaust gas regulations at levels that cannot be satisfied with current internal combustion engine technology, such as Euro 7, and are demanding the development of eco-friendly vehicles through companies' ESG management. Accordingly, vehicle manufacturers are also focusing their efforts on developing eco-friendly vehicles.

그러나, 종래의 전기식 또는 수소연료전지 차륜형 장갑차나, 차륜형장갑차와 유사한 중량의 상용차량의 경우, 기존 내연기관의 엔진을 대용량 구동 모터로 대체하여 전동화 차량을 구성하였으나 변속기, 부변속기, 추진축 등 기계식 동력전달 시스템을 그대로 사용하고 있으므로 구동 효율에 의한 동력 손실은 계속 발생하고 있고, 기존 내연기관 차량 대비 전체적인 동력 시스템이 복잡해지는 문제점이 있었다.However, in the case of conventional electric or hydrogen fuel cell wheeled armored vehicles or commercial vehicles of similar weight to wheeled armored vehicles, the existing internal combustion engine engine was replaced with a large capacity drive motor to form an electric vehicle, but the transmission, subtransmission, and propulsion shaft were constructed. Since the mechanical power transmission system is used as is, power loss due to driving efficiency continues to occur, and there is a problem in that the overall power system becomes more complex compared to existing internal combustion engine vehicles.

또, 종래에는 공간 활용성을 극대화 하면서 시스템을 단순화 시키기 위한 방안으로 인휠모터가 고안되고 있는데, 타이어의 중심부에 모터가 위치하는 특징 때문에 험지 주행이 많은 차륜형장갑차 등 군용차량의 경우, 주행중에 발생하는 노면 충격이 현가 장치를 통해 감쇠되지 않고 모터에 그대로 전해져 이로 인해 내구성이 크게 저하되는 문제점이 있었다.In addition, conventionally, in-wheel motors have been designed as a way to simplify the system while maximizing space utilization. Due to the feature that the motor is located in the center of the tire, in the case of military vehicles such as wheeled armored vehicles that often drive on rough terrain, problems occur during driving. There was a problem in that the shock from the road surface was not attenuated through the suspension device but was transmitted directly to the motor, resulting in a significant decrease in durability.
