Intelligent manufacturing automobile brake disc fatigue strength test system

The invention relates to the technical field of automobile brake disc testing devices, and discloses an intelligent manufacturing automobile brake disc fatigue strength testing system which structurally comprises a mounting plate, a brake disc, a balance degree testing device and a wear resistance testing device.The balance degree testing device is additionally arranged, a rack is driven by a ball screw to move to the position above the brake disc, and the wear resistance of the brake disc is improved; then, the meshing of the meshing column gear drives the rack to move to push the wedge block to move, so that the detection piece is driven to move oppositely to clamp the brake disc, the balance degree of the brake disc can be detected by means of the contact between the pressure sensor on the detection piece and the brake disc, and then the brake disc rotating at a high speed is continuously braked through the brake mechanism. The device can test the wear-resistant fatigue degree of the brake disc, then when
