Abstract

The utility model discloses a heat insulation-type floating disc, which comprises a floating disc body. The floating disc body consists of an outer ring and an inner ring which are coaxially arranged; the outer ring is provided with a plurality of heat dissipation holes; the inner ring is provided with a central axle hole and mounting and fixing holes, wherein the central axle hole is sheathed with a brake axle; and the outer ring and the inner ring are riveted to be fixed through rivets. By adopting the structure, as the heat insulation-type floating disc body disclosed by the utility model consists of the outer ring and the inner ring, and the outer ring and the inner ring are riveted to be fixed through the rivets, the outer ring and brake shoes are in contact friction during the using process, whereas the inner ring is fixedly connected with the brake axle, and thus, heat generated by the friction of the outer ring can be effectively prevented from being transferred to the inner ring and even the brake axle, and the normal operation of a brake system is ensured. Moreover, the outer ring is also additionally provided with the heat dissipation holes, and thereby, the heat dissipation performance of the outer ring is improved, and the outer ring is prevented from deforming after being heated.

Description

The insulation type floating disc

Technical field

The utility model relates to automobile-used braking system, is specifically related to a kind of insulation type floating disc.

Background technique

Floating disc is an important component in the automobile-used braking system, and floating disc is set on the brake axle, and its outside end face rubs mutually with brake shoes and realizes braking; But at present; Existing floating disc is an integrated type floating disc, in use, because floating disc and brake shoes constantly rub; Therefore floating disc outboard end surface temperature is higher usually; Not only cause the temperature distortion of floating disc self easily, but also easily with on the miscellaneous part of heat transfer in the automobile-used braking system such as brake axle, thereby bring infringement for whole automobile-used braking system.

Summary of the invention

To the deficiency of existing technology, the utility model provides a kind of heat sinking function insulation type floating disc preferably.

For realizing above-mentioned purpose; The utility model provides a kind of insulation type floating disc; Comprise the floating disc body, described floating disc body is made up of the outer ring and the inner ring of concentric setting, offers some radiation holes on the outer ring; Inner ring is provided with the central shaft hole that socket-connects with brake axle and installs and fixes the hole, and described outer ring and inner ring are fixed through rivet.

The beneficial effect of the utility model is: adopt said structure, because the floating disc body that the utility model provided is to be made up of outer ring and inner ring, outer ring and inner ring are fixed through rivet; Therefore in use, the outer ring friction that contacts with brake shoes, inner ring then is connected to a fixed with brake axle; Can completely cut off the fricative heat transfer in outer ring effectively to inner ring; Even on the brake axle, ensured the proper functioning of braking system, on the outer ring, also have additional some radiation holes in addition; Improve the thermal diffusivity of outer ring, avoided its temperature distortion.

The utility model can further be set to described outer ring ringwise; Inner ring is installed in the outer ring; The inner ring surface of annular outer ring some extension projections that are circumference uniform distribution that extend internally, extension projection and inner ring outer peripheral surface on the said outer ring are fixed through rivet.

Description of drawings

Fig. 1 is the plan view of the utility model.

Embodiment

As shown in Figure 1ly provided a kind of insulation type floating disc; Comprise floating disc body 1; Described floating disc body 1 is made up of with inner ring 12 outer ring 11 of concentric setting, offers some radiation holes 111 on the outer ring 11, and inner ring 12 is provided with the central shaft hole 121 that socket-connects with brake axle and installs and fixes hole 122; Described outer ring 11 ringwise; Inner ring 12 is installed in the outer ring 11, the inner ring surface of annular outer ring 11 some extension projections 112 that are circumference uniform distribution that extend internally, and the extension projection 112 on the said outer ring 11 and inner ring 12 outer peripheral surfaces are through rivet 3 riveted fixing.

Adopt said structure, because the floating disc body 1 that the utility model provided is to be made up of outer ring 11 and inner ring 12, rivet 3 riveted fixing are passed through with inner ring 12 in outer ring 11; Therefore in use, outer ring 11 friction that contacts with brake shoes, inner ring 12 then and brake axle be connected to a fixed; Can completely cut off outer ring 11 fricative heat transfer effectively to inner ring 12; Even on the brake axle, ensured the proper functioning of braking system, on outer ring 11, also have additional some radiation holes 111 in addition; Improve the thermal diffusivity of outer ring 11, avoided its temperature distortion.
