Technical Field

[0001] The utility model relates to the technical field of automobile parts, and particularly to a clamping combined injection-molded steel pipe transmission cooling oil pipe. Background Art

[0002] As a part of the powertrain, the transmission also plays a crucial role in the vehicle's power performance, fuel consumption and emissions. While improving the vehicle's power performance during driving, the heat generated by gear shifting in the transmission must be cooled through the heat exchange of the transmission oil, and at the same time, sufficient lubricity is provided for the meshing between gears. The traditional transmission cooling injection oil pipe uses a welding process to weld the injection ports of each branch oil pipe to the main oil pipe, which not only has low efficiency but also increases the pollution of iron filings in the pipeline. Therefore, it is very important to provide a cooling oil pipe that can be quickly assembled and has a certain sealing reliability. Summary of the Utility Model
