Problems solved by technology

The anti-warping structure of the brake disc in the prior art all adopts bolt connection, and the bolt connection needs to open holes on the friction disc and the support disc, which not only reduces the effective area of ​​the friction surface of the friction disc, but also dismantles the bolt connection structure. It is not easy to install, which increases the difficulty and workload of the installation of the brake disc

Embodiment 1

[0034] Such as Figure 1 to Figure 9 As shown, the outer hoop locking type anti-warping brake disc of this embodiment includes a support disc 1, an anti-warping outer hoop 3 and two friction discs 2, and the two friction discs 2 are attached to both sides of the support disc 1 respectively. , and the three are clamped and locked by fastening components. Both the support plate 1 and the friction plate 2 are provided with a central through hole, and the anti-warping outer hoop 3 is set on the outer periphery of the support plate 1. The anti-warping outer hoop 3 includes at least two arc outer hoop segments 31, and each arc outer hoop is divided into two parts. The pieces 31 are connected end to end, and the two sides of the arc outer hoop segment 31 are provided with anti-warping baffles 311, and the circumferential surface of the friction disc 2 is provided with anti-warping grooves 21, and the anti-warping baffles on both sides of the arc outer hoop segment 31 The plates 311 ...

Embodiment 2

[0052] Such as Figure 10 As shown, the outer hoop locking type anti-warping brake disc of this embodiment differs from Embodiment 1 only in that:

[0053] In this embodiment, the structure of the arc outer hoop segment 31 is different. Specifically, the two ends of the arc outer hoop segment 31 do not need to be provided with an installation end plate 314, the outer hoop boss 51 is arranged in an L shape, and the outer hoop boss 51 is directly fixed on the end of the arc outer hoop segment 31, In this way, the two outer hoop bosses 51 in the locking structure 5 overlap in the radial direction, the axis of the locking hole 511 is perpendicular to the axis of the brake disc, and a threaded hole or welding is made on the inner outer hoop boss 51 in the radial direction. The nut, the locking hole 511 on the radially outer outer hoop boss 51 is a through hole, which can be locked by the locking bolt 52 . This structure can be directly engaged in the anti-warping groove 21 of the...

Abstract

The invention discloses an outer hoop locking type anti-warping brake disc. The brake disc comprises a supporting disc, an anti-warping outer hoop and two friction discs, wherein the two friction discs are attached to the two sides of the supporting disc correspondingly, the two friction discs and the supporting disc are locked by means of fastening assemblies in a clamped mode, the supporting disc and the friction discs are provided with center through holes correspondingly, the periphery of the supporting disc is sleeved with the anti-warping outer hoop, the anti-warping outer hoop comprises at least two arc outer hoop fragments, the arc outer hoop fragments are connected end to end, anti-warping baffles are arranged on the two sides of the arc outer hoop fragments, anti-warping grooves are formed in the circumferential faces of the friction discs, and the anti-warping baffles on the two sides of the arc outer hoop fragments are arranged in the anti-warping grooves of the two friction discs in a clamped mode correspondingly. According to the brake disc, a split type anti-warping outer hoop is adopted to ensure that the outer sides of the friction discs do not warp, the brake disc is good in connection stability and convenient to disassemble and assemble, the friction surfaces of the friction discs do not need to be occupied, and the friction area of the friction discs is utilized to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of brake devices for vehicles, in particular to an outer hoop-locked anti-warping brake disc. Background technique [0002] At present, most domestic car brakes are disc brakes. There are two main types of disc brakes: shaft-mounted and wheel-mounted. The shaft-mounted brake disc body of high-speed vehicles is usually made of cast steel and is integrally cast. It has high production efficiency and low production cost, and the brake disc structure is mature and reliable. widely used in the class. The anti-warping structure of the brake disc in the prior art all adopts bolt connection, and the bolt connection needs to open holes on the friction disc and the support disc, which not only reduces the effective area of ​​the friction surface of the friction disc, but also dismantles the bolt connection structure. It is not easy to install, which increases the installation difficulty and installation workload of...
