1. A wheel support or a pivot bearing of a vehicle, comprising:
a receiving molding for a ball-joint pin of a track rod provided to change a toe angle of a wheel rotatably secured to the wheel support or pivot bearing and configured to receive a cylindrical shaft portion of the ball-joint pin, wherein the cylindrical shaft portion is located above a lower flared portion of the ball-joint pin, wherein the lower flared portion of the ball-joint pin has a larger diameter than the cylindrical shaft portion of the ball-joint pin; and
an elastomer layer provided at least partially within the receiving molding, wherein the elastomer layer is located at least partly in a force transmission path from the ball-joint pin to the wheel support or pivot bearing and encircles at least the cylindrical shaft portion of the ball-joint pin, wherein
the elastomer layer includes a flared portion at a bottom portion of the elastomer layer with a profile that matches a profile of the lower flared portion of the ball-joint pin,
the elastomer layer includes an elastomeric material that is thicker in a front and rear region with respect to the vehicle than in a left and right region with respect the vehicle such that a displaceability of the ball-joint pin relative to the receiving molding is greater in the longitudinal direction than the transverse direction,
a hollow-cylindrical bush element is provided in the receiving molding, which has the elastomer layer, at least in some sections, between an inner bush provided to receive the ball-joint pin and an outer bush resting on the receiving molding, wherein the outer bush has a lower flared portion and an upper cylinder portion, and wherein the upper cylinder portion is surrounded by the receiving molding along at least a majority of a length of the upper cylinder portion,
the inner bush comprises a collar at an upper end region that extends outward from the ball-joint pin, and
the collar of the inner bush contacts a top nut that is screwed into a top end of the cylindrical shaft portion of the ball-joint pin.
