Technical Field

The utility model relates to a heavy-duty car is with accessory technical field specifically is a balanced suspension crossbeam of resistance to compression for heavy-duty car.

Background

With the development of industry, the scale of industrial production is getting bigger and bigger, heavy vehicles are used more frequently in industrial production and transportation, and because heavy vehicles have heavier weight, a plurality of groups of balanced suspension cross beams are needed to connect the vehicle body and the longitudinal beams so as to ensure the bearing capacity of the vehicle. However, the existing balanced suspension cross beam has the following problems:

1. when a longitudinal beam or a vehicle body part is installed on the existing balance suspension frame cross beam, most of the existing balance suspension frame cross beam is directly connected with the longitudinal beam or the vehicle body part by using a screw rod, when the part is subjected to certain pressure, most of the pressure is directly pressed on the screw rod, so that the pressure bearing of the screw rod is overhigh, the cross beam is of a solid structure, and heavy vehicles have various parts and compact structures, so that the operation space of operators is extremely small in the installation process, and the installation is troublesome;

2. the existing balance suspension beam mostly adopts a thin and long columnar structure as a main body structure of the balance suspension beam, so that when the automobile is subjected to sudden huge pressure caused by long-term use or accidental collision to an automobile body, the bearing capacity of the structure is insufficient, certain elasticity is not provided, and the automobile body is easy to break.

Aiming at the problems, innovative design is urgently needed on the basis of the original balance suspension beam for the heavy-duty vehicle.

SUMMERY OF THE UTILITY MODEL
