Application of nylon hose in automobile brake pipe

Because of its easy assembly, cleanness, anti-aging and corrosion resistance, nylon tubes are widely used by various auto manufacturers around the world. The second automaker has applied nylon 11 pressure pipes on several models, such as the EQ4090F5D and ED1118R series, and also used some nylon tubes on the EQ1902F model. In the future new models, all the traditional steel pipes are gradually adopted. Replaced with nylon tubes.

Because the sealing angles of the nut end and the joint end are not the same, this causes the nut end to ensure that the friction torque of the joint end is greater than the friction torque of the nut end, which effectively prevents the nut from rotating when the nut is tightened. Not only that, but the inner edge of the ferrule is also eliminated, and the outer side of the nylon tube is no longer damaged, and the strength of the detachment is not impaired.

5 Nylon tube cost calculation

The experiment evaluates and studies the use of nylon tubes and steel tubes. According to the following content, the price of nylon tubes should be much lower than that of steel tubes. The reasons are as follows: (1) The total arrangement length is gradually reduced after the use of nylon tubes; (2) Nylon tube can be used in signal circuit, working circuit, gas source circuit and other systems; (3) nylon tube has no molding process; (4) steel tube has no high utilization rate of nylon tube; according to investigation, currently sold steel pipe on the market Each car is 28 yuan higher than the nylon tube. After the nylon tube is used, the number and variety of the pipe joints used by the car are much reduced, and the cost per car can be reduced by another 45 yuan [4].

6 Conclusion

After the car brake system uses nylon tube, although the price of nylon tube and steel tube is almost the same (should be different), there are still many economics in the current enterprise that cannot be statistically economic, such as assembly and reserve transportation. In terms of aspects, reducing workload and simplifying the production process, reducing the failure rate and compensation rate, this is undoubtedly indicating that the economic benefits of using nylon tubes are better (since many are unable to calculate economic benefits, how can they get Is the economic benefit of the nylon tube better?). Therefore, the use of nylon tubes can promote the automotive pipeline technology to a higher level and improve the braking performance of the vehicle.
