The invention discloses a large-scale flat-shaped U-type bolt for a heavy duty vehicle. The large-scale flat-shaped U-type bolt is of a left-right symmetric structure and is characterized in that the top of a first screw and the top of a second screw are respectively provided with threads, and the bottom of the first screw and the bottom of the second screw are connected together through arc-shaped flat steel. By means of the arrangement, the shape of the arc-shaped flat steel is adopted, connecting components of the heavy duty vehicle are better matched, the biting phenomenon cannot happen, the mechanical performance of the heavy duty vehicle is ensured, the service life of the components is prolonged, and the maintenance cost is reduced.
Description
technical field [0001] The invention relates to a U-shaped bolt, in particular to a large-size flat U-shaped bolt used on heavy vehicles. Background technique [0002] Large-size flat U-bolts for heavy-duty vehicles are connecting parts, and its performance directly affects the quality of the entire heavy-duty vehicle. The shape of the flat U-bolt is unique. First, it has a large size and a special shape; second, it vibrates with the vehicle and the working conditions are poor; The above conditions require that the flat U-bolt must have high strength, high temperature resistance and corrosion resistance, so the company developed the U-bolt. Contents of the invention [0003] The object of the present invention is to provide a large-size flat U-bolt for heavy-duty vehicles with high strength, high temperature resistance, corrosion resistance and good anti-loosening performance. [0004] In order to achieve the above object, the present invention has a left-right symmetric...
