A wheel suspension for a motor vehicle, particularly for a steerable drive wheel, includes a steering knuckle support and at least one transverse arm, which, at a first end thereof, is swivel-mounted about a horizontal axis, and, at the second end thereof, opposite the first end, forming a resting point for the steering knuckle support, is hinged onto the steering knuckle support. The steering knuckle support has a wheel hub with an outer rest surface for receiving a vehicle wheel that turns via the wheel hub. The wheel hub has, radially within the outer rest surface, a through opening for receiving a flange shaft that turns with the vehicle wheel.

1. A wheel suspension for a steerable drive wheel of a motor vehicle, comprising: a steering knuckle support;a first upper transverse arm and a second lower transverse arm, each of which, at a first end thereof, is swivel-mounted about a horizontal axis, and each of which at a second end thereof, forms a resting point for the steering knuckle support and is hinged onto the steering knuckle support;wherein each resting point includes a universal joint including two hinge joints positioned one after another in a flow of forces from the steering knuckle support to the first end of the respective transverse arm; the two hinge joints each forming two substantially and mutually perpendicular axes of rotation, the two hinge joints including a first hinge joint including a first axis of rotation which is substantially perpendicular to a line extending in a horizontal direction, and a second hinge joint including a second axis of rotation which extends at least substantially parallel to the horizontal axis of the swivel mount at the first end of the transverse arm;wherein each first hinge joint includes a hole in the steering knuckle support, two roller bearings positioned next to each other commonly on the first axis of rotation and a pin mounted in the hole by the two roller bearings and fastened to the second hinge joint;wherein the first axis of rotation of each of the first hinge joints is on a common axis of rotation, and the two pins of the first hinge joints are positioned at a clear distance from each other on the common axis of rotation and without direct connection to each other so that a line joining the two pins of the first hinge joints does not intersect any element of the wheel suspension between the two pins, the two pins being only indirectly mechanically connected to one another, with the only indirect mechanical connection between the two pins, other than a chassis of the motor vehicle, being provided by the steering knuckle support;wherein the steering knuckle support includes a wheel hub with an outer rest surface for receiving a vehicle wheel and, radially within the outer rest surface, a through opening;a rotating flange shaft that turns with the vehicle wheel positioned in the through opening, the rotating flange shaft including a first axial end and a second end opposite the first axial end, the second end including a drive flange that extends inside or axially outside the steering knuckle support and includes connectors for transmitting a power of a drive shaft;a wheel hub bearing provided on the outer rest surface to allow rotation of the vehicle wheel about the outer rest surface. 2. The wheel suspension according to claim 1, wherein each second hinge joint is formed by a knuckle joint at the second end of the transverse arm together and includes two roller bearings and a hinge bolt, with the hinge bolt being mounted with the two roller bearings in the knuckle joint, the hinge bolt supporting the pin and being inserted therein with at least one chosen from a form fitting and a tight fitting. 3. The wheel suspension according to claim 1, wherein the wheel suspension is a double-wishbone suspension. 4. The wheel suspension according to claim 1, and further comprising: a wheel mount that is mounted on the outer support surface of the wheel hub by the wheel hub bearing, the wheel mount including a threaded pin or internal thread for fastening a rim of the vehicle wheel,wherein the flange shaft extends within the through opening of the wheel hub at the first axial end, and axially outside the wheel hub, and includes a radial flange that is, at a front, connected to the wheel mount, so that the flange shaft and the wheel mount turn together.
