AI Technical Summary

Technical Problem

Commercial vehicle fuel tanks are prone to shifting during use, which can cause impacts to the mudguards or urea tanks. Even with current technology, the shifting problem persists after prolonged use.

Method used

It adopts a limit support device and an automatic pre-tightening device, including a fixed frame, a hoop, a raised structure, a sheet-like pressure sensor, an electric transmission mechanism, and an on-board ECU. The sensor monitors the tendency of the fuel tank to move, and the motor pre-tightening bolts tighten the hoop to achieve active anti-movement.

Benefits of technology

It effectively prevents the fuel tank from moving around, reduces the risk of impact, improves assembly efficiency, reduces maintenance costs, and achieves a higher level of anti-movement effect.
