Abstract

The invention discloses a tyre rolling resistance testing method and a chassis dynamometer. The tyre rolling resistance testing method comprises that: the chassis dynamometer performs reverse drag test on a tyre in a whole vehicle testing state to obtain a reverse drag resistance; the chassis dynamometer performs no-load test to obtain the internal resistance of a drum; and the chassis dynamometer calculates the rolling resistance of the tyre of the tested vehicle according to the reverse drag resistance and the internal resistance of the drum, wherein the rolling resistance of the tyre is the difference obtained by subtracting the internal resistance of the drum from the reverse drag resistance. The whole vehicle is tested by adopting the chassis dynamometer, and the rolling resistance of the tyre of the tested vehicle can be obtained, so that the influence of uncertain factors such as external environment, human operation and the like on the vehicle power test is reduced, the testing result is accurate, and the method is simple and convenient to operate and easy to implement.

Description

technical field [0001] The invention relates to vehicle measurement technology, in particular to a tire rolling resistance test method and a chassis dynamometer. Background technique [0002] As an important part of the car structure, tires have an important impact on the fuel economy of the car. The greater the rolling resistance of the tire, the greater the road resistance of the car, and the greater the fuel consumption, which increases the exhaust emission and pollutes the environment. In addition, the rolling resistance of the tires of the car also has a great influence on the wear of the tires. Therefore, no matter from the aspect of energy saving or environmental protection, it is very important to test the rolling resistance of automobile tires. [0003] In the prior art, the tire rolling resistance of automobiles is tested on a tire rolling resistance testing machine. During the test, a single tire is fixed on the tire rolling resistance testing machine. Under th...
