A front-axle bracket for motor vehicles has two accommodations spaced apart from one another in the longitudinal vehicle direction in each instance for the bearing locations for pivoting mounting of one or two wheel guide elements, in each instance, such as transverse control arms or A-arms, accommodations for attachment of the front-axle bracket as a pre-finished unit, together with pre-assembled assemblies, on the vehicle body, and at least individual ones of accommodations for attachment of the steering gear mechanism, for attachment of the stabilizer, and for mounting of a pendulum support. The front-axle bracket is produced as a component that is in one piece with these accommodations and connects them with one another. At least individual ones of the accommodations are integrated into the front-axle bracket by way of rod-shaped connecting elements, in framework-like manner.
