[0028] The application discloses a brake rotating ramp. Referring to Figure 1 A brake rotating ramp comprises a plurality of ramp bodies 1, which are arranged in a circumferential direction, and one high side of one ramp body 1 is connected with the low side of an adjacent ramp body 1. The plurality of ramp bodies 1 are integrally formed. The connection between the inner ring body and the ramp body 1 is cancelled, the structure of the rotating ramp is simplified, and thus the casting or forging of the rotating ramp is accelerated, and the manufacturing of the rotating ramp is facilitated.

The arrangement of the positioning groove 14 can realize the installation and positioning of the rotating ramp, and thus the installation of the rotating ramp is facilitated.

[0030] Referring to Figure 1 The inner side surface of the ramp body 1 is formed with a connecting tooth shape 2, and the upper surface of the connecting tooth shape 2 is flush with the first plane 12 of the ramp body 1. The length of the connecting tooth shape 2 can exceed the length of a single ramp body 1, so that a longer connecting tooth shape 2 can be arranged, and thus the connection of the rotating ramp is facilitated. A plurality of weight-reducing cavities 11 are arranged at intervals on the outer side surface of the ramp body 1. The weight of the rotating ramp is reduced, and the raw materials for manufacturing the rotating ramp are saved. The bottom wall of the weight-reducing cavity 11 close to the high side of the ramp body 1 is arranged with a fixing screw hole 15. The side surface of the ramp body 1 is arranged with a limiting hole 16 perpendicular to the fixing screw hole 15 at the fixing screw hole 15, and the limiting hole 16 is in communication with the fixing screw hole 15.
