Car water tank lower beam assembly role
The main functions of the lower beam assembly of the automotive water tank include improving installation stability, simplifying construction, lightweight and increasing the front compartment installation space . By integrating into existing tank fixtures, the lower tank beam can replace traditional support ribs and connection points, thereby simplifying the structure and achieving lightweight. Such a design not only strengthens the beam itself, but also frees up valuable front cabin space, providing a double boost to vehicle performance and practicality .
In addition, the lower beam assembly of the water tank also assumes the role of ensuring the torsional rigidity of the frame and bearing longitudinal loads. It is connected by riveting to ensure sufficient strength and stiffness to withstand the load of the car and the impact of the wheels .
The lower beam assembly of the automobile water tank is an important part of the automobile body, which is mainly used to fix the automobile water tank and condenser and play a supporting role.
The specific functions of the lower beam assembly of the water tank include:
Secure the water tank and condenser : the lower beam assembly of the water tank is bolted or spot-welded to the surrounding headlight support and longitudinal beam to ensure the stable installation of the water tank and condenser .
bearing and support : although the bearing force of the lower beam assembly of the water tank is not large, it mainly plays the role of supporting the water tank to ensure the stability and safety of the water tank .
affects the appearance of the body : because the lower beam assembly of the water tank is arranged with the front bumper mounting point and the hair cover buffer block support point, its installation accuracy will have a great impact on the appearance of the body .
The material and structural style of the lower beam assembly of the water tank are various, and the common ones are metal material, resin material and metal + resin material. Among them, the non-removable tank frame is the most common type, usually made of metal material, form a gantry shape, bolted or spot-welded to .
car water tank lower beam assembly failure mainly includes the following situations:
Settlement or deformation : Long-term use or improper maintenance may cause settlement or deformation of the lower beam of the tank. In case of settlement, adjust bolts can be used to fine-tune; If deformation occurs, it is necessary to replace the lower beam of the tank .
crack or fracture : in special circumstances, the lower beam of the water tank may crack or fracture, then the new lower beam of the water tank should be replaced in time.
welded joint off : Because the lower beam of the water tank is usually connected by welding, the welded joint may fall off during use, resulting in the loss of the bearing capacity of the beam. At this time, you need to re-weld or replace a new tank lower beam .
Cause and impact of the fault
These failures will cause the lower beam of the tank to be unable to effectively support the bottom of the tank, affecting the bearing capacity and stability of the tank. Specific impacts include:
tank deformation : causes the bottom of the tank deformation, affecting the normal use of the tank.
Water leakage : The water tank may leak, affecting the normal operation of the cooling system.
impact on body appearance : Due to the installation accuracy, the appearance of the body may be affected.
Maintenance methods and preventive measures
maintenance method :
Adjustment bolt adjustment : For settlement, you can use the adjustment bolt for fine adjustment.
Replacement of new parts : in case of deformation, crack or break, a new tank lower beam will need to be replaced.
rewelding : in case the welded joint falls off, it is necessary to reweld or replace the lower beam of the tank.
Preventive measures :
regular inspection : regularly check the lower beam of the water tank for problems, timely maintenance and repair.
