To provide an improved brake drum for a vehicle.SOLUTION: A brake drum (10), particularly for commercial vehicles, includes a drum housing (11) configured in a cup-like shape and having a cylindrical brake surface inside, and a flange (12) configured on the end surface of the drum housing. The flange (12) has a plurality of bolt holes (30) with hole axes (31) for insertion of wheel bolts (25), and the hole axes (31) are arranged on a common hole circle. The flange (12) has, on its flange inner surface (17), around each bolt hole (30) a flat abutment surface for an expanded bolt head (26) of each wheel bolt (25). In the brake drum (10), each abutment surface is configured as a flat bottom surface of a recess in the flange inner surface (17), and each recess is bounded by a contour that is guided around the hole axis (31) with a varying contour spacing relative to the hole axis (31).SELECTED DRAWING: Figure 1

    【課題】改良された車両用ブレーキドラムの提供。【解決手段】特に商用車用ブレーキドラム(10)はカップ状に構成され、内側に円筒状ブレーキ面を備えるドラム筐体(11)、ドラム筐体端面に構成されたフランジ(12)とを含み、フランジ(12)は、ホイールボルト(25)の挿通のために穴軸(31)を有する複数のボルト穴(30)を備え、穴軸(31)は共通の穴円の上に配置され、フランジ(12)はそのフランジ内面(17)に、それぞれのホイールボルト(25)の拡張されたボルト頭部(26)のための平坦な当接面を各々のボルト穴(30)の周りに備える、ブレーキドラム(10)において、それぞれの当接面はフランジ内面(17)にある凹部の平坦な底面として構成され、それぞれの凹部は、穴軸(31)を中心として案内された、穴軸(31)に対する輪郭の間隔が変動している輪郭によって区切られることを特徴とする。【選択図】図1
