Description

Technical Field

[0001] This utility model relates to the field of dump trucks, and in particular to a single-plate stamped structure for a dump truck subframe. Background Technology

[0002] The subframe of a dump truck is an important component, mainly used to support the truck body and hydraulic system. During operation, it shares the load with the main frame to bear the torsion and bending of the frame, as well as the dynamic load caused by uneven road surfaces. With the increasing requirements for environmental protection and lightweighting, the application prospects of solid plate stamping technology in the manufacturing of dump truck subframes are broad. In the future, this technology will further optimize mold design and stamping processes to adapt to more types and higher strength materials, promoting the sustainable development of the dump truck industry.

Furthermore, the fixed plate is an integral stamped structure, and both sides of the fixed plate are folded, which can improve the overall support strength of the fixed plate and effectively improve the overall service life of the device.

[0009] Furthermore, the other ends of the two rotating rods are respectively rotatably connected to the side walls of the two second connecting blocks;

[0010] The above technical solution effectively installs the rotating rod.

[0011] Furthermore, the movable end of the hydraulic rod is rotatably connected to the side wall of the first connecting block;

[0017] Furthermore, the bottom two sides of the fixing plate are adapted to the top of the support frame;

[0018] The above technical solution facilitates the lowering of the subframe.

[0019] Furthermore, some of the connecting rods are square tube structures;

[0020] The above technical solutions effectively provide good assistance.
