The utility model discloses an automobile fan clutch. The automobile fan clutch is mainly formed by connecting a fan fixed disk with a transmission shaft in a rotating manner by virtue of a three-ring (namely an inner ring, a middle ring and an outer ring) bearing; a driving disk is fixedly connected with the end face of the inner side of a middle ring sleeve of the three-ring bearing, and a soft magnet on the inner end face of the driving disk corresponds to a plurality of permanent magnets which are distributed on and connected with the end face of an inner cavity of the fan fixed disk; the outer end face of the driving disk is connected with a spring piece elastically connected with an inner actuation disk. The driving disk and the fan fixed disk share one three-ring bearing and realize the connection transmission, a second bearing used by the driving disk in the prior art is eliminated, the compact product structure and the small volume are realized, and the production cost is reduced; the three-ring bear
