The first transition arc 201 and the second transition arc 202 are designed, so that stress at the joint of the connecting cylinder part 2 and the disc body part can be dispersed, and the integral strength is improved.
As shown in fig. 1, the outer side surface of the second disc body 302 is provided with an annular inner groove 3021, which corresponds to the inward extension of the whole disc surface of the second disc body 302, and since the portion of the second disc body 302 close to the inner ring has a connection function, the other disc surface portion is an effective brake disc surface, and since the disc surface area having the connection function is unchanged, the increase of the whole disc surface area of the second disc body 302 corresponds to the increase of the area of the effective brake disc surface, that is, the increase of the effective brake radius. Since the effective braking surface of the second disc 302 is corresponding and equal to the effective braking surface of the first disc 301, the area of the effective braking surface of the first disc is also increased. Under the condition of constant moment, the effective braking radius is increased, the clamping force of the brake caliper can be reduced, the unit pressure of the friction plate is reduced, the damage of the friction plate is delayed, the unit pressure of the disc body of the brake disc is reduced, and the disc body is prevented from cracking due to overlarge clamping force.
