Problems solved by technology
According to the test, when the electromagnetic liquid-cooled retarder continues to work, the temperature on the inner surface of the stator can reach 285°C, and the temperature on the working surface of the salient pole rotor is also about 90°C due to the heat radiation of the stator, and the temperature of the stator will radiate to the inner coil , the coil itself generates heat when it is working, and at the same time, due to the heat radiation of the stator and other reasons, the temperature of the coil increases, the resistance becomes larger, and the excitation current becomes smaller, which affects the continuous braking performance of the electromagnetic liquid-cooled retarder, thereby affecting the safe driving of the vehicle

The invention discloses a rotor of an electromagnetic liquid cooling retarder, comprising a rotor body, which is a disk structure with a through hole in the middle; a plurality of uniformly-spaced gear teeth are arranged on the outer edge of the rotor body; an open groove is disposed between two adjacent teeth; and the open groove is a groove recessed from the outer edge of the rotor body toward the center of the rotor body. By improving the structure of the conventional rotor, the rotor can efficiently disperse the heat in the coil to increase the magnetic utilization rate of the entire structure and extend the continuous braking time of the electromagnetic liquid cooling retarder.
Description
technical field [0001] The invention relates to the technical field of electromagnetic liquid-cooled retarder accessories, in particular to a rotor used in passenger cars or heavy-duty vehicles. Background technique [0002] Electromagnetic liquid cooled retarder, as an auxiliary braking device, is increasingly used in buses and heavy commercial vehicles. The device consists of a fixed disc, a first rotor, a coil, a stator and a second rotor. It is installed at the rear end of the gearbox and connected to the transmission shaft. It realizes non-contact braking through the principle of electromagnetic induction, reduces the wear of the main brake, and prolongs the braking time. Hoof service life. [0003] The working principle of the electromagnetic liquid-cooled retarder is that the excitation current is passed into the retarder coil during operation, and a circuit is formed between the first rotor, air gap, stator, air gap, second rotor and connecting cylinder. When the s...
