Abstract

The present invention relates to a method for quickly testing car wheel edge powder characteristics. It is characterized by that according to a certain testing process it can use chassis dynamometer machine to test the power characteristics of car wheel edge. Under the condition of that the drum speed of the chassis dynamometer machine is changed with car wheel, but is not stable, i.e. when the drum implements variable motion in a certain rotational speed, the absorption power value of the chassis dynamometer machine can be measured, and an inaccurate wheel edge power value under said speed can be obtained, then the inaccurate wheel edge power value can be corrected so as to obtain the accurate wheel edge power value.

Description

Technical field

[0001] The invention relates to a method for testing the power characteristic of the wheel of an automobile, in particular to a method for quickly testing the power characteristic of the wheel of the automobile based on a chassis dynamometer to obtain the power characteristic of the wheel of the automobile. Background technique

[0002] Currently, the state of the art for rapid testing of wheel power characteristics of vehicles using chassis dynamometers is nil.

[0003] Obtaining the wheel power characteristics is the most important test item when conducting vehicle dynamic performance tests and diesel vehicle load-deceleration conditions smoke emission tests. The wheel power characteristic of the automobile refers to the relationship between the power of the engine output power transmitted to the wheels through a certain gear of the transmission system and the driving speed of the vehicle when the throttle opening of the engine is constant. Since the automo...
