Inter-cooling pipe fixing device

Abstract

The invention discloses an inter-cooling pipe fixing device. The inter-cooling pipe fixing device comprises a Z-shaped connecting support, a first semicircular hoop and a second semicircular hoop. The Z-shaped connecting support comprises a first installation face connected with a vehicle frame in a matched mode, a second installation face connected with the first semicircular hoop in a matched mode and a connecting face for connecting the two installation faces. A first long-strip hole is formed in the first installation face, and a second long-strip hole is formed in the second installation face; the first semicircular hoop is formed by a first clamping part and two first tightly-clamping parts, and installation holes are formed in the two first tightly-clamping parts respectively; the second semicircular hoop is formed by a second clamping part and two second tightly-clamping parts, installation holes are formed in the two second tightly-clamping parts respectively, and the second tightly-clamping parts are connected with the first tightly-clamping parts through bolts. By means of the inter-cooling pipe fixing device, the support structure is optimized, the rigidity and the strength of the support structure are improved, and it is guaranteed that pipe fixing is firm, reliable and durable.

Description

technical field [0001] The invention belongs to the technical field of passenger car manufacturing, and in particular refers to an intercooling pipe fixing device used in passenger cars. Background technique [0002] The design of the existing intercooler pipe fixing device for passenger cars is unreasonable, the rigidity and strength are poor, and the vibration generated during engine operation and vehicle operation is likely to cause fatigue and fracture of the bracket. And because the stiffness and strength of the existing support structure are poor, the vibration generated by the engine operation causes a large relative movement between the pipe and the vehicle frame, which accelerates the trend of fatigue fracture of the support. [0003] Due to design structural defects or improper installation of the existing intercooler pipe fixing device for passenger cars, it is difficult to ensure that there is sufficient clearance between the pipe and the frame, and it is easy to...

AI Technical Summary

Problems solved by technology

[0002] The design of the existing intercooler pipe fixing device for passenger cars is unreasonable, the rigidity and strength are poor, and the vibration generated during the operation of the engine and the vehicle is easy to cause fatigue and fracture of the bracket

Moreover, due to the poor rigidity and strength of the existing support structure, the vibration generated by the engine operation causes a large relative movement between the pipe and the frame, which accelerates the trend of fatigue fracture of the support

[0003] Due to design structural defects or improper installation of the existing intercooling pipe fixing device for passenger cars, it is difficult to ensure that there is enough clearance between the pipe and the frame, and it is easy to cause interference between the pipe and the frame and make abnormal noises

[0004] The existing intercooler pipe fixing device for passenger cars is inconvenient to adjust following changes in the installation position and angle of the pipe, resulting in poor applicability (the change in the installation position of the pipe is mainly due to the offset of the engine installation position caused by manufacturing or assembly)

[0005] Due to the low adjustability of the existing passenger car engine intercooler pipe fixing bracket installation, after the engine installation is displaced, it is easy to appear that the reserved installation and fixing holes on the frame cannot be used, and the connecting bracket is welded on the frame. Poor maintainability and disassembly
