[0025] The utility model discloses an embodiment of the utility model will be clearly and completely described below with the drawings in the embodiment of the utility model to the technical scheme in the embodiment of the utility model, obviously, the described embodiment only is a part of embodiment of the utility model, instead of all the embodiment. Based on the embodiment in the utility model, all other embodiments that the ordinary skill in the art obtains without making creative labor belong to the range of protection of the utility model.

[0026] The utility model provides two technical schemes:

[0027] Figures 1 to 3 Show the first kind of implementation: a riveting structure of power-on type brake rotor 1, including rotor 1, the cross section of rotor 1 is hollow T-shaped arrangement, the outer ring of rotor 1 is set with a plurality of first step groove 2 with rotor 1 axis as center and equal angle spacing, the outside of rotor 1 is sleeved with armature 3, and armature 3 is circular ring arrangement, and the position of armature 3 opposite first step groove 2 is set with second step groove 4;First step groove 2 and second step groove 4 are riveted with rivet 5, and the tail of rivet 5 forms hollow cavity. The number of first step groove 2, second step groove 4 and rivet 5 is six, and the adjacent two rivets 5 are reversely arranged, and the part of rotor 1 outer wall opposite armature 3 forms counterbore 6.

[0028] The inner wall of counterbore 6 is provided with brake spring 7 at the position opposite first step groove 2, and brake spring 7 is annular arrangement, and rivet 5 penetrates brake spring 7;Brake spring 7 is usually designed as the form of elastic sheet with elasticity, and the spring not only has excellent deformation recovery ability, but also can quickly recover to its original shape after being subjected to external force, and the pre-tightening force of the spring can ensure that rotor 1 and armature 3 always keep close contact.

[0029] The number of first step groove 2, second step groove 4 and rivet 5 is six, and the adjacent two rivets 5 are reversely arranged, and the layout not only guarantees the uniformity and stability of connection, but also helps to balance the stress generated in the riveting process, further reduces the possibility of component deformation;The application sets rivet 5 into half hollow shape, so that the riveting pressure of rivet 5 is small, and the damage of riveted part is small, and the solid part can bear greater shear force.

[0030] Figure 4The second embodiment is shown, and the main difference with the first embodiment is that the inner wall of the first step groove 2 and the second step groove 4 at the end away from each other is chamfered; it is helpful to check and replace the rivet 5 and other components more easily during maintenance.

[0031] Working principle:

[0032] The riveting structure of the patent takes advantage of the special properties of the semi-hollow rivet 5, combined with the step groove design of the rotor 1 and the armature 3, to achieve a stable and less deformed connection.

[0033] The semi-hollow rivet 5 with a hollow inner cavity is used to connect the armature 3 and the rotor 1, and the rivet 5 requires relatively small pressure during riveting, and the hollow design can disperse the stress during riveting; compared with solid rivets 5, the riveting pressure required by semi-hollow rivets 5 is greatly reduced, thereby reducing the risk of deforming the rotor 1 and the armature 3; at the same time, the solid part of the semi-hollow rivet 5 can still withstand a large shear force, ensuring the strength and stability of the connection.

[0034] By opening step grooves on the rotor 1 and the armature 3 and using semi-hollow screws for riveting, a more stable mechanical connection is achieved, and this connection method avoids the problem of thread loosening and screw falling off in traditional screw connection, reducing the risk of accidents and hidden dangers.
