Abstract

The present invention discloses a brake device for the wheels of an automotive vehicle which includes a wheel-sided brake drum and a vehicle-sided mud guard that engages in a non-contact manner with a circumferential web into an annular recess in the end surface of the brake drum opposite the mud guard in order to provide a labyrinth-type seal. In conventional brake devices, the mud guard along with a welded annular web typically has a two-part design. In contrast thereto, the present invention proposes that the mud guard be punched and deep drawn from sheet metal and that the circumferential web be integrally designed with the mud guard by noncutting shaping.

Claims

1. A brake device for the wheels of an automotive vehicle that includes a wheel-sided brake drum, comprising:

a mud guard made of sheet metal by punching and deepdrawing operations, wherein said mud guard includes a circumferential web that is integrally designed with said mud guard by noncutting shaping on at least a part of said mud guard'"'"'s circumference, wherein said web is comprised of a double layer of material that projects vertically in relation to a main plane of said mud guard and is formed from a radially inward half web and from a radially outward half web.

2. A brake device for the wheels of an automotive vehicle that includes a wheel-sided brake drum, comprising:

a mud guard made of sheet metal by punching and deepdrawing operations, wherein said mud guard includes a circumferential web that is integrally designed with said mud guard by noncutting shaping on at least a part of a circumference of said mud guard, wherein said mud guard includes a radially inward half web and spaced therefrom a radially outward half web, wherein both of said half webs extend substantially vertical to a main plane of said mud guard, and wherein a sheet-metal portion is interposed between said half webs, said sheet metal portion generally extending in a plane.

3. A brake device as claimed in claim 2, wherein said radially outward half web, when viewed in a cross-section, extends in a conically outwardly expanding fashion from said main plane of said mud guard and passes in a rounded fashion into said main plane of said mud guard and into a parallel plane of said sheet-metal portion.
