Description
technical field [0001] The invention relates to an eddy current retarder test system, in particular to an eddy current retarder test system based on accurate temperature detection. Background technique [0002] Eddy current retarder is an auxiliary braking device for automobiles, commonly known as electric brake, which is mainly used in large passenger cars, urban buses and heavy trucks. The device is installed between the car drive axle and the gearbox, and realizes non-contact braking through the principle of electromagnetic induction. [0003] The eddy current retarder test system is to test the performance of the eddy current retarder before leaving the factory, so as to ensure that the qualified eddy current retarder can be circulated in the market, so the eddy current retarder test system with good performance is Appears to be important. However, the traditional eddy current retarder test system cannot accurately detect the working temperature of the eddy current ret...
