摘要

The invention relates to an axle (1) of a motor.The axle (1) of a motor comprises two longitudinal control arms (2) and a connecting crossbeam (3) connected to the two longitudinal control arms. The crossbeam (3) includes a profile (7) with a U-shaped cross-section opening, the profile is provided with a web (10) and side limbs (11,12) blending from the longitudinal side of the web. The opening of the profile (7) in the installation position points to a road. The side limb (11) on the front side of a vehicle is in the end portions (E1, E2) of the profile (7) and has a reduced height (H) relative to a central portion (M) of the profile (7). The height (H) of the side limb (11) on the front side of the vehicle changes through a longitudinal side, circular arc or elliptical arc recess (9). The invention also relates to a method for the manufacture of a crossbeam (3) for an axle (1) of a motor
