The present invention relates to a structure, a material, and a manufacturing process of a guide core device installed to be mounted at an accurate position without being detached when the air filter is mounted on an air cleaner device of a commercial vehicle, and more specifically, the material and fabrication of a guide core device. By changing the process, the weight of the air cleaner device is reduced, and the manufacturing process is reduced. The present invention relates to an apparatus designed to facilitate the convenience of the operator and to obtain a cost reduction effect due to the material change and the reduction of the manufacturing process.

In the engine for internal combustion engines, in order to obtain power, the explosive force obtained by burning the gas mixed in an appropriate ratio of fuel and air by external factors (electric flame, compression ignition, etc.) is converted into power. Since the air contained in the mixed gas is sucked through the suction device in the atmosphere and used, the air is sucked in the state of containing a large amount of dust or impurities in the atmosphere. When combustion of the air containing impurities during engine combustion, incomplete combustion and fine particles may cause deterioration of engine performance, wear of engine parts such as cylinder blocks and pistons, or fatal coupling factors. Therefore, in general, an air cleaner device is installed in the intake section of the engine to remove impurities of air required for engine combustion, and the air cleaner device is equipped with an air filter that plays a role of substantially filtration of air.

In the case of air filters used in commercial vehicles, unlike private cars, the filtration area is much higher, which greatly increases the size and weight of the air filters. When mounting a large and heavy air filter to the air cleaner unit, the guide core unit is installed in the center of the air cleaner unit in order to install the bolts for mounting the cover in one place by the operator in the correct position.

Previously, such a guide core device was made of steel plate, and the air cleaner device was assembled through a plurality of work assembly processes in which the guide core device, which was made through several manufacturing processes separately from the housing of the air cleaner device, as separate accessories (bolts, nuts, etc.) in the housing. Is produced as a finished product.

As such, the conventional internal devices have a problem of increasing the weight and product cost of the entire air cleaner device due to materials, accessories, and manufacturing processes, resulting in a weakening of the market price competitiveness.

The purpose of the present invention for solving the above problems is to mount the air filter on the air cleaner device of a commercial vehicle in the correct position, and the material of the guide core device with the bolt installed to assemble the air filter and the cover from the steel series housing and By using the same material or plastic series and injecting the housing into a unitary structure with the bolts inserted during the housing injection in the manufacturing process, the operator's convenience is reduced due to the weight reduction of the air cleaner device and the reduction of the manufacturing process. It is an object of the present invention to provide an air cleaner device for a commercial vehicle that can achieve cost reduction effect due to material change and manufacturing process reduction.

The air cleaner device of the commercial vehicle of the present invention for achieving the above object is equipped with an air filter to serve as the body of the whole device, the inlet and outlet, the housing in which the guide core is formed, preventing impurities from entering and replacing the air filter And a cover, which serves as a fixing function, an air filter for filtering impurities from the outside, an inlet for introducing outside air, an outlet for allowing the filtered air to flow into the engine, and an easy installation of the air filter to be fixed to the cover. It is characterized in that the bolt consists of a guide core inserted.

Configuration of the air cleaner device of a commercial vehicle according to the present invention will be described below with reference to the accompanying drawings.

1 is an exploded view showing a representative apparatus of an air cleaner device of a commercial vehicle according to the present invention.

2 is a cross-sectional view showing an overall mounted state of a representative device of an air cleaner device of a commercial vehicle according to the present invention.

3 is a cross-sectional view of a front view of the housing of the air cleaner device according to the present invention.

As shown in FIG. 1, the construction and mounting state of a commercial vehicle air cleaner device serves as a body of the entire device by mounting an air filter, a housing having an inlet and an outlet, a guide core formed therein, preventing impurities from entering from the outside, and replacing the air filter. And a cover, which serves as a fixing function, an air filter for filtering impurities from the outside, an inlet for introducing outside air, an outlet for allowing the filtered air to flow into the engine, and easy installation of the air filter, and for fixing with a cover. It consists of a guide core with a bolt inserted.

According to the present invention configured as described above, the material of the guide core device with bolts is installed in the steel series such as housing or plastic so as to mount the air filter in the air cleaner device of the commercial vehicle at the correct position and assemble the air filter and the cover. By using the series, and in the manufacturing process, the injection molding is integrated with the housing while the bolt is inserted, so that the weight of the air cleaner device is reduced and the manufacturing process is reduced for the convenience of the operator and for material change and production. There is an effect to provide an air cleaner device that can reduce the cost of the process reduction.
