자동차용 프론트휠하우스와 대쉬판넬의 보강구조{Reinforcement of front wheel house and dash panel for vehicle}Reinforcement of front wheel house and dash panel for vehicle}

본 발명은 자동차용 프론트휠하우스와 대쉬판넬의 보강구조에 관한 것으로서, 더욱더 상세하게는 엔진에서 발생되는 진동이 차실로 유입되는 것이 효과적으로 억제되도록 함과 동시에 엔진에서 발생되는 강체모드와 프론트휠하우스 및 대쉬판넬의 자체 굽힘모드에 의해 공진이 발생하여 프론트휠하우스와 대쉬판넬이 변형되는 것이 방지되도록 하는 자동차용 프론트휠하우스와 대쉬판넬의 보강구조에 관한 것이다.The present invention relates to a reinforcing structure of a front wheel house and a dash panel for an automobile, and more particularly, the rigid body mode and the front wheel house generated from the engine while effectively suppressing the inflow of vibration generated from the engine into the cabin and The present invention relates to a reinforcing structure of a vehicle front wheel house and a dash panel in which resonance is generated by a self bending mode of the dash panel to prevent the front wheel house and the dash panel from being deformed.

일반적으로 자동차의 전면 좌우 양측에는 프론트휠하우스가 설치되고, 상기 프론트휠하우스의 후단부는 차실과 엔진룸을 경계로 설치되는 대쉬판넬의 좌우 양측부에 각각 용착되어 있다.In general, the front wheel house is installed on the front left and right sides of the vehicle, and the rear end of the front wheel house is welded to both left and right sides of the dash panel which is installed at the boundary between the vehicle compartment and the engine room.

그러나 종래에는 엔진의 공회전시 발생되는 진동이 휠하우스로 전달되고, 상기 휠하우스로 전달된 진동은 대쉬판넬을 통해 직접 차실로 전달이 이루어지게 됨으로서, 차실에 탑승한 승원의 승차감을 저하시키게 되는 문제점이 있었다.However, in the related art, the vibration generated during idling of the engine is transmitted to the wheelhouse, and the vibration transmitted to the wheelhouse is directly transmitted to the vehicle cabin through the dash panel, thereby reducing the riding comfort of the occupant in the cabin. There was this.

따라서 종래에도 상기와 같은 문제점을 해결하기 위해 엔진의 진동을 줄이어 차체로 전달되는 진동이 저감되도록 하고 있으나, 이 역시도 엔진에서 발생되는 강체모드와 프론트휠 및 대쉬판넬의 자체 굽힘모드에 의해 공진이 발생하여 프론트휠하우스와 대쉬판넬이 변형되게 되는 문제점이 있었다.Therefore, in order to solve the problems as described above, the vibration transmitted to the vehicle body is reduced by reducing the vibration of the engine, but this also causes resonance due to the rigid mode generated from the engine and the self-bending modes of the front wheel and the dash panel. There was a problem that the front wheel house and the dash panel is deformed.

본 발명의 목적은 상기 종래와 같은 문제점을 해결하기 위해, 자동차의 전면 좌우 양측에 프론트휠하우스가 설치되고, 상기 프론트휠하우스의 후단부는 차실과 엔진룸을 경계로 설치되는 대쉬판넬의 좌우 양측부에 각각 용착되는 것에 있어서, 상기 대쉬판넬과 상기 대쉬판넬 용착되어 있는 대쉬로어멤버 및 프론트휠하우스의 강성이 향상되도록 프론트휠하우스에 용착되어 있는 휠하우스멤버에 일측면이 접하도록 보강판을 설치하여, 상기 대쉬판넬과 프론트휠하우스 굽힘모드시의 공진 주파수가 19.2㎐에서 21.83㎐로 2.61㎐가 상승되도록 함으로서, 엔진의 공회전시 발생된 강체보드주파수(일반적으로 7~17㎐)와 대쉬판넬과 프론트휠하우스의 굽힘모드시의 공진 주파수가 분리되어 차량에 발생되는 진동이 저감되면서 승차감 및 차실에 탑승한 승원의 안전성이 향상되도록 하는 자동차용 프론트휠하우스와 대쉬판넬의 보강구조를 제공하는 데 있다.An object of the present invention, in order to solve the problems as described above, the front wheel house is installed on the front left and right sides of the vehicle, the rear end of the front wheel house is installed on both sides of the dash panel which is installed at the boundary between the vehicle compartment and the engine room In each of the welding on the dash panel, the dash panel and the dash lower member and the front wheel house welded to the wheel house member welded to the front wheel house so that the rigidity of the front wheel house to install the reinforcement plate to contact In this case, the resonant frequency of the dash panel and the front wheel house bending mode is increased by 2.61 kHz from 19.2 21 to 21.83 ,, so that the rigid board frequency generated during idling of the engine (generally 7 ~ 17 ㎐) The resonance frequency in the bending mode of the wheel house is separated to reduce the vibration generated in the vehicle. It is to provide a reinforcement structure of the front wheel house and dash panel for automobiles to improve the safety.
