Problems solved by technology

Therefore, in the emergency braking process of the ABS braking system, if the wheel slip rate is greater than 15-20%, it indicates that the ABS braking system is not in good condition, and the ability to control the wheel brake locking is reduced or even lost.

Embodiment Construction

[0025] The method for measuring wheel slip rate of the present invention, the method comprises the following steps:

[0026] (1) Wheel 1 is introduced in the drum group 3 that is made of driving drum 31 and driven drum 32 that is connected with driving motor 2;

[0027] (2) Control the driving cylinder 41 of the slip rate test drum 4 to lift, so that the slip rate test drum 4 is fully in contact with the wheel 1;

[0028] (3) Make the drum group 3 drive the wheel 1 to rotate at the test speed;

[0029] (4) When the test speed is reached, the wheel 1 is braked urgently; at the same time, the braking distance signals of the driving drum 31 and the sliding rate testing drum 4 are respectively collected, and the braking time from the beginning of braking to the end of braking is recorded. , thus calculate the angular velocity of the drive roller 31 and the slip rate test roller 4;

[0030] (5) Utilize the angular velocity of driving drum 31 to multiply the radius of driving drum...

Abstract

The present invention relates to a method for measuring slip rate of wheel and detection equipment for implementing said method. The invented detection equipment includes base frame and four groups of drum groups. The shaft end of driving drum shaft is equipped with a driving drum speedometer, between driving drum and driven drum of every group of drums a slip rate detection device is set. Said invention also includes a programmable controller for data acquisition and processing the signal output end of the driving drum speedometer and slip rate testing drum speedometer can be connected with signal input end of programmable controller.

Description

technical field [0001] The invention relates to a method for detecting wheel slip rate. The invention also relates to a detection device for implementing the method to measure the wheel slip rate. Background technique [0002] Automobile braking performance is an important condition to ensure the safe driving of automobiles. Governments of various countries have proposed minimum braking performance requirements for automobiles through regulations or mandatory standards. In the past two years, with the gradual increase of imported models, the anti-lock braking system has become the most basic configuration of all types of new production mid-to-high-end cars, and some high-end buses and trucks have also begun to be equipped with anti-lock braking systems. [0003] Antilock Braking System (ABS for short) means that the car can automatically adjust the brake pressure during the braking process to prevent the wheels from locking to obtain the best braking performance, including ...
