Abstract

The utility model discloses a cut off type structure, can rolled drum brake dust ring. The breach of cut off type is equipped with in the bottom of dust ring to in the inside residual moisture's of stopper discharge, the dust ring uses the sheet material type as the steel band, can direct roll forming. The utility model discloses a dust ring is equipped with the breach of the type of cutting off to realize the smooth discharge of the inside moisture of stopper, use neotype manufacturing process, reduce the manufacturing process, reduce development cost, improve product quality.

Description

A kind of cut off type structure, can the drum brake dust ring of roll extrusion

Technical field

The utility model relate to a kind of automotive brake parts, especially relate to a kind of cut off type structure, can the drum brake dust ring of roll extrusion.

Background technique

Along with the development of automobile industry, almost every is all equipped with automobile, and this also makes increasing user be concerned about the performance of automobile; Feed back in cold area of heavy rainfull, morning, vehicle cannot start, and intake mainly due to brake backing plate and brake drum cooperation place, the not easily draining of dust ring structure, and making has water to remain in break, caused friction plate and brake drum internal surface to freeze, adhesion.Existing most dust ring is all unnotched, or has the breach do not cut off, and portions of client feedback friction plate and brake drum are paddled posterior synechia.

Model utility content

Technical problem to be solved in the utility model just there is provided a kind of cut off type structure, can the drum brake dust ring of roll extrusion, with cut-out type breach, dust ring is conducive to draining, and the direct roll forming of steel band can be used, use new process, reduce manufacturing process, reduce development cost, improve quality of product.

For solving the problems of the technologies described above, the utility model adopts following technological scheme:

The breach of cut-out type is provided with in the bottom of described dust ring, and roll forming, so that the discharge of brake inside residual moisture.

Described breach is positioned at the lower middle side part of described dust ring.

Described dust ring uses plate type to be steel band, can directly roll forming.

Prior art often adopts impact briquetting, and the adoptable rolling technology of the utility model is novel process, can reducing operation quantity in manufacture process, can cut down finished cost when ensureing that accessory size meets the demands.

The beneficial effects of the utility model are as follows:

Under dust ring of the present utility model, middle side part is provided with the breach of cut-out type, so that the discharge of brake inside residual moisture.

And dust ring of the present utility model adopts plate type to be steel band, can directly roll forming, when ensureing that accessory size meets the demands, stamping process plate type is square stock, compare stamping process, roll forming can reduce operation quantity in manufacture process, reduces material and cuts down finished cost.

Embodiment

Below in conjunction with the drawings and specific embodiments, installation and using process, the utility model is further described:

As depicted in figs. 1 and 2, the utility model is the breach 1 being provided with cut-out type in the bottom of dust ring 2, so that the discharge of brake inside residual moisture, its breach 1 specifically can be positioned at the lower middle side part of dust ring 2.

Having the dust ring 2 after breach 1 can use plate type for steel band, can directly roll forming.

Of the present utility modelly specifically to be implemented as follows:

As shown in Figure 5 and Figure 6, Dustproof circle 2 of the present utility model is welded on braking bottom board 3, and consistent with base plate center, on this dust ring, arc notch is concentric with braking bottom board 3 gluing consent, is provided with the breach 1 of cut-out type at the lower middle side part of dust ring 2, after brake assembly entrucking, wheel cylinder assembly 4 is directed upwardly, and this breach 1 is positioned at the intermediate portion, downside of brake assembly, as shown in Figure 3 and Figure 4, when intaking in break, can discharge along this breach 1 place.

Dust ring 2 of the present utility model adopts plate type to be steel band, uses special roll unit, direct roll forming, then arc making v notch v.Be square stock for stamping process plate type, need Blanking, rush intermediate hole, arc making v notch v, according to punching press, the breach 1 processing cut-out type cannot be realized, when ensureing that accessory size meets the demands, compare stamping process, roll forming can reduce operation quantity in manufacture process, reduce material to cut down finished cost, and the breach 1 that can realize cut-out type is processed.

Claims

1. one kind cut off type structure, can the drum brake dust ring of roll extrusion, it is characterized in that: the breach (1) being provided with cut-out type in the bottom of described dust ring (2), so that the discharge of brake inside residual moisture, dust ring (2) uses roll forming.

2. according to claim 1 a kind of cut off type structure, can the drum brake dust ring of roll extrusion, it is characterized in that: described breach is positioned at the lower middle side part of described dust ring (2).

3. according to claim 1 a kind of cut off type structure, can the drum brake dust ring of roll extrusion, it is characterized in that: described dust ring (2) uses plate type to be steel band.
