The collector ring is used for transmitting a tiny millivolt signal of a thermocouple arranged on a wheel brake pad to a data acquisition system arranged on a vehicle body through an electric brush. The disadvantages are that: firstly, the temperature of a contact point rotating at a high speed is higher than the conventional temperature, so that the measurement error of a thermocouple is caused; secondly, the contact point is contacted with a resistor in a high-speed rotating mode, so that a thermocouple measurement error is caused; thirdly, because of the relative movement between the wheels and the vehicle body in the running process, force in an uncertain direction between the rotor and the stator cannot be avoided, so that the collector ring is very easy to damage; fourthly, the volume is large, the width is about 15cm, the width exceeds the width of a general car rearview mirror, and the car rearview mirror is inconvenient to drive when the road surface condition is complex; fifthly, the weight is large, the total mass is about 2kg after the collector ring is added, more mass is added to the tire, and dynamic balance during high-speed test is not used; sixth, installation is inconvenient, and the structure takes more time to assemble on a test vehicle; seventh, the internal rolling bearings have a limited life.
