Abstract
A heat shield element for a brake caliper of a disc brake, capable of providing complete radial and axial protection for the brake caliper, which is arranged straddling a disc brake disc and having a vehicle-side elongated portion and an opposite wheel-side elongated portion connected to each other by at least one caliper bridge. The element has a heat shield element body having at least two opposite snap engagement tongues adapted to snap-engage a portion of the brake caliper to interpose the heat shield element body between the brake caliper and the disc brake disc and support the heat shield element engaged with the brake caliper.
Claims9
A heat shield element for a brake caliper of a disc brake straddling a disc of a disc brake and having a vehicle-side elongated portion and an opposite wheel-side elongated portion connected to each other by a caliper bridge, said heat shield element comprising a heat shield element body which comprises:
- at least two opposite snap engagement tongues suitable for snap engaging a portion of the brake caliper to interpose said heat shield element body between said brake caliper and said disc of disc brake and support said heat shield element engaged to said brake caliper;
- at least one arched back extended along a circumferential direction following a curved line from one inner end to an outer end;
- wherein said heat shield element body comprises at least two side shield portions opposite each other, each extending orthogonal to said circumferential direction in a radial plane, said at least two side shield portions forming with said arched back, transversely to said circumferential direction, an inverted “U” section suitable for placing said heat shield element body astride said disc of disc brake;
- and
- wherein said at least two opposite snap engagement tongues are arranged one at said inner end of the arched back, the other at said outer end of the arched back, so as to mutually embrace and engage said at least one caliper bridge placing said arched back between said at least one caliper bridge and said disc of disc brake and each of said at least two side shield portions between a portion of said elongated portions and said disc of disc brake as a heat protection of the brake caliper;
- wherein said heat shield element body, with said at least one arched back and the at least two side shield portions, comprises caliper spacers which constitute the only resting elements of the sheet to the brake caliper;
- and
- said spacers are adapted to rest on the brake caliper and create an air space between said sheet body and said brake caliper;
- and said spacers have a limited point-like contact area between the heat shield element and the brake caliper to limit heat transfer between the heat shield element and the brake caliper.
A method for obtaining a heat shield element, comprising the steps of:
- providing a mold;
- shaping, said heat shield element body;
- and
- forming an arched back;
- and
- subsequently or simultaneously forming at least two opposite snap engagement tongues;
- and
- subsequently or simultaneously forming at least two opposite side shield portions orthogonal to said arched back;
- providing a flat sheet;
- cutting said flat sheet to shape;
- molding an arched back;
- and
- subsequently or simultaneously molding at least two opposite snap engagement tongues;
- and
- subsequently or simultaneously molding at least two opposite side shield portions orthogonal to said arched back;
- and/or wherein
- the step of cutting said flat sheet to shape is a shearing step;
- and/or wherein
- subsequently or simultaneously with the molding of the arched back spacers are molded suitable for limiting the resting areas of the element on a caliper;
- and/or wherein
- shearing to shape provides for shearing a plurality of side shield portions and the step of engagement of side shield portions arranged side by side and contiguous to each other is provided;
- and/or wherein
- said thermal shield element is snap engaged to a caliper bridge, so that it shields heat radiation of a brake disc;
- and/or wherein
- said heat shield element is snap engaged to a caliper bridge, so as to allow the passage of air between the heat shield element and the brake caliper.
