Description

brake disc

This creation is about a brake disc.

The braking devices of today's vehicles, such as automobiles, locomotives or bicycles, are mainly disc brakes for better braking and deceleration effects. For example, disc brakes include fixed brake discs and floating discs. Generally speaking, a floating disk includes inner and outer disks and a fixing element. The inner and outer disks are connected by the fixing element, and the inner and outer disks and a positioning ring are elastically pressed against the inner and outer disks by the elastic pieces in the fixing element. between to solve the vibration problem generated when braking.

Among them, the conventional shrapnel and the positioning ring are connected by rivets through pressing and pressing, so that the shrapnel and the positioning ring cannot be stably combined. The pressure cannot evenly press the positioning ring, the structure is more complicated, and the combination stability is poor.

Therefore, it is necessary to provide a novel and progressive brake disc to solve the above problems.

The main purpose of this creation is to provide a brake disc whose components can be assembled effectively and stably.

In order to achieve the above object, the present invention provides a brake disc, including: an inner disc, including a plurality of first assembly structures arranged at intervals in the circumferential direction; an outer disc, surrounding the inner disc, including a plurality of circumferentially spaced apart The second assembling structure, the plurality of second assembling structures and the plurality of first assembling structures are radially concave and convex compatible; the plurality of blocking members are respectively opposite to each other across the plurality of first assembling structures two opposite sides of the connecting structure and the plurality of second assembling structures; and a plurality of riveting pieces, which pass through two ends of each of the blocking pieces and the inner plate to riveted the plurality of riveting pieces and the inner plate.
