Description

Technical Field

[0001] The present application relates to the field of automobile air intake pipes, and in particular to a lightweight air intake pipe for commercial vehicles. Background Art

[0002] The function of the automobile engine intake system is mainly to deliver clean, dry, sufficient and stable air to the engine to meet the needs of the engine, and to prevent impurities and large dust particles in the air from entering the engine combustion chamber and causing abnormal wear of the engine. Another important function of the intake system is to reduce noise. The intake noise not only affects the passing noise of the whole vehicle, but also affects the noise inside the vehicle, which has a great impact on the comfort of the ride. Usually the intake system can be divided into two parts: the engine intake pipe multi-branch system and the air intake system. The air intake system includes an air filter, a filter element, a resonance cavity, an intake pipe, an intake interface, etc. The existing intake pipe and the air filter are connected by a simple clamp, but after the clamp has been used for a long time, its elasticity is easy to decrease, thereby affecting the firmness of the connection between the intake pipe and the air filter.

[0003] Patent application number 202322824261.2 discloses a lightweight automobile air filter intake pipe, including an air filter, one side of the air filter is horizontally connected to a connecting pipe, a sleeve is sleeved in the connecting pipe, the end of the sleeve is connected to the intake pipe, an annular groove is provided on the outer edge of the connecting pipe, an upper clamping ring and a lower clamping ring are respectively clamped in the annular groove, and the upper clamping ring and the lower clamping ring are fixed to each other by bolts. The utility model improves the firmness of the connection between the intake pipe and the air filter by connecting the intake pipe and the air filter through the upper clamping ring and the lower clamping ring, and connecting the upper clamping ring and the lower clamping ring by bolts, sealing pins, springs and guide rods.

[0004] In the above structure, bolts and retaining rings are used to install the intake pipe. Although the installation method using multiple fasteners can increase the stability of the intake pipe, it will lead to poor convenience in disassembly and maintenance of the intake pipe. The air will vibrate during the flow in the intake pipe, and the bolts will be easily loosened due to the influence of vibration during use. Utility Model Content
