Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing:

[0020] like figure 1 As shown, a method for testing and evaluating the performance of the truck cooling module suspension system, the cooling module assembly structure includes a radiator 1, an intercooler 2, a condenser 3, a wind protection mechanism 4, a right main mount 5, and a vehicle frame 6. Right auxiliary mount 7, left main mount 8, left auxiliary mount 9. The intercooler 2, condenser 3, and wind protection mechanism 4 are installed on the radiator 1 through brackets, etc., and the intercooler 2, condenser 3, wind protection mechanism 4, and radiator 1 are assembled into a whole, which is called a cooling module. . One end of the right main mount 5 , the right auxiliary mount 7 , the left main mount 8 , and the left auxiliary mount 9 are connected to the cooling module, and the other end is connected to the vehicle frame 6 . In this form, the cooling module is i...

Abstract

The invention relates to the technical field of automobile cooling system matching, and particularly relates to a truck cooling module suspension system performance test and evaluation method. Duringtesting, testing points are a radiator, intercooler four corners and main and auxiliary suspension positions of a cooling module, testing is carried out in a whole vehicle assembling state, testing can be carried out in two states, one state is that a vehicle is in a neutral gear, does not run and has no vehicle speed, and the other state is a vehicle full-load normal driving state. In the two states, a vehicle engine idling operation condition, an engine rated rotating speed operation condition and an engine maximum torque rotating speed operation condition are tested respectively. And the two states are tested through sensors, three working conditions are adopted for each state, data under six conditions are obtained, and then the performance of the cooling module suspension system is evaluated according to the obtained data. According to the method, the performance of the truck matched with different cooling module suspension systems and the influence of the cooling module suspension systems on the performance of the cooling module can be compared and evaluated, and product development is guided.

Description

technical field [0001] The invention relates to the technical field of automobile cooling system matching, in particular to the technical field of testing and evaluating the performance of the cooling module suspension system of the cooling system, in particular to a method for testing and evaluating the performance of the cooling module mounting system of a truck. Background technique [0002] With the development of automobile technology, automobile design tools and methods are gradually increasing and becoming more and more perfect, but automobile requirements are also getting higher and higher, automobile design requires refinement, and every automobile part design must pay attention to details. The car cooling system is the most important system of the car power system. The core part of the cooling system is the cooling module. The cooling module is an important part because of its high cost. The cooling module is installed on the frame through the cooling suspension sy...
