Abstract

The invention provides a test system for testing comprehensive performance of an eddy current retarder and a test method thereof. The test system comprises the components of a personal computer, a dynamometer system, a torque and rotating speed sensor, an eddy current retarder, an electric controller and a power analyzer. The test system can continuously measure the indexes such as moment characteristic, heat fade characteristic, zero-load wind resistance and power loss of the eddy current retarder at each speed. The test system has advantages of relatively complete function, complete data acquisition, high speed regulation performance and wide test range.

Description

technical field [0001] The invention relates to a test system and a test method for measuring the comprehensive performance of an eddy current retarder. Background technique [0002] The eddy current retarder is a way of auxiliary braking of passenger cars, commonly known as "electric brake". Mainly used in large passenger cars, urban public transport vehicles and heavy trucks. Between the car drive axle and the gearbox, the non-contact braking is realized through the principle of electromagnetic induction. When we apply DC power to the rotor coil of the retarder in a certain way (pushing the hand gear switch of the retarder, or stepping on the brake pedal), a magnetic field will be generated in the rotor coil, and the magnetic field will be in the adjacent core, A loop is formed between the magnetic pole plate, the air gap, and the rotor. At this time, if there is relative motion between the rotor and the rotor, this motion is equivalent to the conductor cutting the...
