Design requirements of brake drum
TIME：2019.12.31
Brake Drum design requirements: Brake Drum design is not appropriate, when the variability of heat; Brake Drum Force imbalance, will also produce mechanical deformation, resulting in bad contact with the hoof and drum, leading to pedal force and stroke increase; Brake Drum working surface roundness is too large, it can also cause self-locking and produce vibration and noise. Therefore, the brake drum should have enough wall thickness, and outside surface near the part of the opening to cast a circumferential or axial reinforcement to increase the strength. These stiffeners also play the role of heat dissipation, can reduce the friction surface temperature, shorten the brake cooling time, so that the energy capacity increased by 35% ~ 40% . Brake drum working face is generally assembled with the wheel hub, bearing hole positioning for finishing. Mini car requires roundness and coaxiality tolerance ≤0.03 mm, radial runout ≤0.05 mm, static unbalance ≤1.5 cm.
