[0022] The utility model discloses a set up of integrated booster support and intercooler support, which is a support structure.

[0023] The utility model discloses a set up of integrated booster support and intercooler support, which is a support structure.

[0024] The first connecting part 11 is designed as a cuboid structure, which can ensure sufficient contact area with the supercharger 2 and facilitate subsequent machining and installation operations.

[0025] Meanwhile, a delicate oil passage is designed inside the first connecting part 11, which provides a path for the return oil passage 8 and the oil inlet passage 9 to communicate with each other. The return oil passage 8 is located on the side of the first connecting part 11 close to the output end of the supercharger 2, which functions to collect and guide the used lubricating oil of the supercharger 2 back to the oil pan. The oil inlet passage 9 is responsible for guiding the lubricating oil from the oil pump to the bearing and other core parts of the supercharger 2, providing necessary lubrication and cooling for the supercharger 2 during high-speed operation, and ensuring its stable performance.

[0026] The second connecting part 12 extends obliquely from the connection between the first connecting part 11 and the base 10, and from the side of the first connecting part 11 and the top surface of the base 10 to the outside of the base 10, and finally forms a vertical plane at the end of the extension, which is tightly connected to the intercooler 5 through two rows of bolt holes. This oblique extension structure can better disperse the stress generated by the weight and working vibration of the intercooler 5 after the supercharger 2 is installed by hoisting tools, and at the same time provides a stable and angle-appropriate support platform for the intercooler 5, ensuring that the intercooler 5 can normally play its role of cooling the intake air during operation, and improving the intake efficiency of the engine.

[0027] In addition, the overall cast structure of the bracket 1 and the internal careful arrangement of multiple reinforcing ribs make it have excellent mechanical properties. The reasonable distribution of reinforcing ribs effectively enhances the rigidity of the bracket 1, so that it can easily bear the weight of the supercharger 2 and the intercooler 5, and resist the vibration and impact force generated during long-term high-load operation of the engine, ensuring the reliability and stability of the entire device.

[0028] The integrated design of the utility model integrates the functions of supercharger support and intercooler support into one, and greatly simplifies the components of the engine by arranging the oil inlet and return passages 8 inside the bracket 1. Compared with the traditional split support structure, this design reduces the development cost of multiple parts and reduces the machining process and assembly difficulty in the production process, thereby significantly improving the production efficiency. In addition, the compact layout design not only saves valuable space inside the engine, but also helps to optimize the overall performance of the engine, so that it can maintain high-efficiency operation under various working conditions, providing strong power for the vehicle while improving fuel economy and reliability.

[0029] The utility model discloses through the scientific and reasonable shape structure between each component, accurate position layout and the stable and reliable connecting mode, has realized the effective support of supercharger 2 and intercooler 5 and the collaborative work, has provided solid structural basis for the high performance operation of engine, has the remarkable technical innovation and practical application value.
