Automobile generator assembly and automobile

The invention discloses an automobile generator assembly. The automobile generator assembly comprises a collector ring assembly and a rotor assembly which is connected with the collector ring assembly. The rotor assembly comprises a rotor shaft. A knurling section is arranged on one end of the rotor shaft. The collector ring assembly comprises a collector ring liner. The knurling section is embedded in a cavity of the collector ring liner. A first cylindrical cavity section, a tapered cavity section and a second cylindrical cavity section are successively arranged from the insertion direction of the rotor shaft in the cavity. The large end of the tapered cavity section is connected with the first cylindrical cavity section. The small end of the tapered cavity section is connected with the second cylindrical cavity section. The inner diameter of the first cylindrical cavity section is greater than the outer diameter of the knurling section. The inner diameter of the second cylindrical cavity section is less than the outer diameter of the knurling section. According to the invention, radial cumulative tension of the collector ring liner in a collector ring assembly installation process is reduced; radial cracks of the collector ring liner are avoided; and the reliability of connection is ensured. The invention further discloses an automobile with the generator assembly.
