Embodiment Construction

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

[0020] Such as 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 i...

Abstract

The invention relates to the technical field of automobile cooling system matching, in particular to a method for testing and evaluating the performance of a truck cooling module suspension system. During the test, the test points are the radiator, the four corners of the intercooler and the main and auxiliary suspension positions of the cooling module. It is carried out in the assembled state of the whole vehicle. It can be tested in two states, one is when the vehicle is in neutral and not driving, No speed state; one is the normal driving state with the vehicle fully loaded. In the two states, test the vehicle engine idling operating condition, the engine rated speed operating condition, and the engine maximum torque operating condition. The sensors are used to test the above two states, and there are three working conditions for each state, and the data in six cases are obtained, and then the performance of the cooling module suspension system is evaluated according to the obtained data. The method of the invention can compare and evaluate the performance of different cooling module suspension systems matched with the truck, and the influence of the cooling module suspension system on the performance of the cold module, so as to guide product development.

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...
