To provide a structure for attaching brake flanges to an axle case, with a simple configuration, capable of reducing stress at welded portions where the brake flanges are attached to the axle case, exhibiting high durability at low cost against tensile stress generated at the welded portions by vehicle weight and road surface reaction force, as well as, against shear stress generated at the welded portions by braking torque during braking, and suppressing occurrence of cracks initiating at the welded portions.SOLUTION: A structure for attaching brake flanges to an axle case comprises: disc-shaped brake flanges 2 each having a hole inserted into each end of an axle case 1 in a vehicle width direction; cylindrical portions 6 each extending in the vehicle width direction from the hole of the brake flange 2 along a surface of the axle case 1; slot portions 7 formed in a circumferential direction and communicating with an inside and an outside of the cylindrical portion 6; and welding beads 8 each formed welding an inner peripheral surface of the slot portion 7 and the surface of the axle case 1 along the circumferential direction of the slot portion 7.SELECTED DRAWING: Figure 4

    【課題】簡単な構成で、ブレーキフランジをアクスルケースに取り付ける溶接部における応力を軽減でき、車重、路面反力により溶接部に生じる引張応力と、制動時の制動トルクにより溶接部に生じる剪断応力とに対し、低コストで高い耐久性を発揮でき、溶接部からの亀裂発生を抑制できるアクスルケースのブレーキフランジ取付構造を提供する。【解決手段】アクスルケース1の車幅方向両端部に夫々挿通された孔明き円板状のブレーキフランジ2と、ブレーキフランジ2の孔からアクスルケース1の表面に沿って車幅方向に延出された円筒部6と、円筒部6にその内外を連通して周方向に形成されたスロット部7と、スロット部7の内周面とアクスルケース1の表面とをスロット部7の周方向に沿って溶接して成る溶接ビード8とを備えている。【選択図】図4
