Full-automatic re-tightening device for fuel tank strap of heavy vehicle

Abstract

The invention discloses a full-automatic re-tightening device for a fuel tank strap of a heavy vehicle, and mainly relates to the technical field of automobile safety. The device comprises pressure sensors which are mounted between a strap and an oil tank, a re-tightening motor mounted on one side of a fastening bolt, and a control system, wherein a gear is mounted on an output shaft of the re-tightening motor, and teeth meshed with the gear are arranged on the fastening bolt; and the pressure sensor and the re-tightening motor are in signal connection with the control system. The tightness condition of the fuel tank strap can be monitored in real time, so that the tightness is fully automatically adjusted, silt is prevented from entering a gap between the strap and the fuel tank, and the firmness, the safety and the service life of the fuel tank are guaranteed.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to a full-automatic tightening device for heavy-duty vehicle fuel tank straps. Background technique [0002] With the continuous improvement of my country's automobile technology and the continuous development of highway construction, heavy-duty vehicle transportation has become a trend in the transportation industry, but people's understanding of the maintenance of heavy-duty vehicles is still limited to changing oil and filter elements, often ignoring the need for maintenance of heavy-duty vehicles. Retightening of fuel tank straps. In fact, when the strap is loose, if it is not fastened in time, the sand will enter the gap between the strap and the fuel tank, which will cause excessive wear of the fuel tank, and in severe cases, it will cause oil leakage from the fuel tank, resulting in the failure of the fuel tank. reduced service life.

[0002] With the continuous improvement of my country's automobile technology and the continuous development of highway construction, heavy-duty vehicle transportation has become a trend in the transportation industry, but people's understanding of the maintenance of heavy-duty vehicles is still limited to changing oil and filter elements, often ignoring the need for maintenance of heavy-duty vehicles. Retightening of fuel tank straps

In fact, when the strap is loose, if it is not fastened in time, the sand will enter the gap between the strap and the fuel tank, which will cause excessive wear of the fuel tank, and in severe cases, it will cause oil leakage from the fuel tank, resulting in the failure of the fuel tank. reduced service life

[0003] According to the maintenance requirements of the fuel tank, the fuel tank strap needs to be retightened every 5,000 kilometers. At present, there is only a technical solution for the manual retightening of the fuel tank strap. During use, when the heavy-duty vehicle reaches the specified maintenance mileage of the fuel tank strap, the driver often forgets to retighten the fuel tank strap, or does not pay attention to the retightening of the fuel tank strap, which will cause sediment to enter In the gap between the strap and the tank

[0004] In addition, the tightness of the fuel tank strap bolts is not only affected by the mileage, but also by the quality of the driving road. When the driver drives on a bumpy road for a long time, the fuel tank strap will be more likely to loosen. The problem of loosening of the strap may occur before the kilometer, and the driver cannot judge whether the fuel tank strap needs to be re-tightened at the first time, resulting in the phenomenon of fuel tank leakage from time to time, which poses a great safety hazard
