However, this method does not reduce the force exerted on the bolts and does not protect them. When braking for a long time or with strong braking, the bolts are prone to deformation or loosening. For example, a Chinese patent discloses "a split brake disc", and its application number is: "202223202016.X", which includes a fixing mechanism, a first disc body and a second disc body. The fixing mechanism includes a fixed disc seat, and a snap-in slot is opened on one side of the fixed disc seat. The upper part of the first disc body is provided with a snap-in slot seat, and the first disc body is connected to one side of the fixed disc seat through the snap-in slot seat, and the second disc body is connected to one side of the first disc body. Through the above structure, the brake disc is convenient for heat dissipation, but it does not protect the bolts and does not reduce the force exerted on the bolts during braking, which is easy to cause the bolts to deform or loosen during long-term or strong braking, and has limitations when used.
