Description

하이브리드 전기자동차용 브레이크 캘리퍼장치{APPARATUS OF BRAKE VEHICLE}Brake Caliper Device for Hybrid Electric Vehicles {APPARATUS OF BRAKE VEHICLE}

본 발명은 하이브리드 전기자동차용 브레이크 캘리퍼장치에 관한 것으로서, 보다 상세히는 전기자동차의 주요부인 브레이크 캘리퍼장치의 중량을 현저히 감소시킴은 물론 전기모터의 작동과 함께 캘리퍼장치가 원활하게 작동하도록 구성하여 장치의 성능을 향상시키기 위한 하이브리드 전기자동차용 브레이크 캘리퍼장치에 관한 것이다. The present invention relates to a brake caliper device for a hybrid electric vehicle, and more particularly, to significantly reduce the weight of the brake caliper device, which is a main part of the electric vehicle, as well as to configure the caliper device to operate smoothly together with the operation of the electric motor. The present invention relates to a brake caliper device for a hybrid electric vehicle for improving performance.

하이브리드 전기자동차는 자동차 산업의 발전으로 친환경적이며, 저연비를 추구하고 있으며, 내연기관 자동차로 인해 발생하는 온난화, 산성비, 오존층 파괴 등의 환경오염과 다가오는 석유자원의 고갈 문제 등이 대두됨에 따라, 경량화, 최적화 등의 기술을 통한 연비개선 등을 도모하고 있다. 또한, 기존의 내연기관 동력장치를 대체하는 방법을 위해 많은 연구가 진행되고 있다.Hybrid electric vehicles are eco-friendly due to the development of the automobile industry, and are pursuing low fuel consumption. We are trying to improve fuel efficiency through technologies such as optimization. In addition, a lot of research is in progress for replacing the existing internal combustion engine power unit.

대체 동력장치의 기술로는 H2엔진, CNG엔진, EV(Electric Vehicle) 및 FCEV(Fuel Cell Electric Vechicle) 등의 기술개발이 이루어졌다. EV의 경우 저소 음, emission, 복잡한 변속장치의 불필요 등의 장점을 가지지만, 짧은 주행거리, 낮은 충전효율, 고가격, 부족한 가속성능 등의 문제점들이 산재해 있다.Alternative power plants include H2 engines, CNG engines, electric vehicles (EVs), and fuel cell electric vessels (FCEVs). EV has advantages such as low noise, emission, and the need for complicated transmissions, but there are problems such as short driving distance, low charging efficiency, high price, and insufficient acceleration performance.

이러한 문제점에 대해 중·단기적인 관점에서 HEV(Hybrid Electric Vehicle)가 해결책으로 주목받고 있다. 여기서, 회생제동 시스템은 HEV의 주행거리 및 에너지 효율 증대를 위해 제동시 차량의 운동에너지로 모터(발전기)를 구동시켜 발행하는 전기에너지를 배터리로 회수하는 장치이다. In the medium and short term, a hybrid electric vehicle (HEV) has been attracting attention as a solution to this problem. Here, the regenerative braking system is a device for recovering the electric energy issued by driving the motor (generator) with the kinetic energy of the vehicle during braking to increase the mileage and energy efficiency of the HEV.

회생제동의 비율이 높을수록 에너지 회수량은 높지만 무엇보다 중요한 것은 차량의 안전성임으로, 회생제동제동력이 충분하지 않은 경우 일반 마찰제동력을 증가시켜 운전자의 감속 요구를 반드시 만족시켜 주어야 한다.The higher the rate of regenerative braking, the higher the energy recovery, but most importantly the safety of the vehicle. If the regenerative braking force is not sufficient, the general friction braking force must be increased to satisfy the driver's deceleration requirements.

특히, 회생제동장치의 주요부인 전자제어 브레이크(EMB: Electro-Mechanical Brake)는 브레이크장치가 전기모터에 의해 작동되는 시스템으로, 전기에너지를 기반으로 하는 하이브리드 자동차와 회생제동 시스템의 결합성이 매우 좋은 시스템이며, 안전성 개선에 이바지하는 매우 중요한 기술이라 하겠다.In particular, the electro-mechanical brake (EMB), which is a major part of the regenerative braking system, is a system in which the brake system is operated by an electric motor, and the coupling between the hybrid vehicle and the regenerative braking system based on electric energy is very good. It is a system and very important technology that contributes to safety improvement.

상기와 같이 전기자동차의 회생제동장치의 주요부를 구성하는 전자제어 브레이크장치는 브레이크 캘리퍼장치가 막대한 비중을 차지하고 있는 반면, 지속적인 시스템의 개발이 요구되고 있다.As described above, in the electronically controlled brake device that constitutes the main part of the regenerative braking device of the electric vehicle, the brake caliper device occupies a huge proportion, but the development of a continuous system is required.

As mentioned above, the weight of the vehicle is closely related to the acceleration, fuel economy and braking force, so special efforts and developments are made to reduce the total weight of the vehicle and the weight of each component.

하지만, 기존의 브레이크 캘리퍼장치에 있어서 대부분의 중량을 차치하는 캘리퍼몸체가 주물로 구성됨으로 인해 상대적으로 무거운 문제점이 있었다.However, in the conventional brake caliper device, there is a relatively heavy problem because most of the weight of the caliper body is composed of castings.

또한, 캘리퍼 하우징에 억지끼움하여 전기모터의 피스톤과 마찰접촉하는 부트부재의 경우, 합성고무부재로 이루어져 있어서 피스톤과의 반복적인 마찰접촉에 의해 헐거워지면서 누설되거나 하우징으로부터 이탈되는 문제점이 발생하였다. 특히 브레이크패드에서 발생하는 패드 입자이나 이물질들이 피스톤을 따라 전기모터로 유입되는 심각한 결점이 발생하며, 이는 곧 전기모터의 오작동 및 파손은 물론 브레이크 캘리퍼장치의 고장으로 유발하며 제동력을 상실하는 심각한 문제점이 있었다.In addition, in the case of a boot member which is pressed into the caliper housing and frictionally contacts the piston of the electric motor, the boot member is made of a synthetic rubber member, which is loosened due to repeated frictional contact with the piston, or has been leaked from the housing. In particular, serious defects in which pad particles or foreign substances generated in the brake pads flow into the electric motor along the piston are caused, which causes malfunction and breakdown of the electric motor as well as failure of the brake caliper device and loss of braking force. there was.
