Abstract

Wheel suspension has a steering knuckle support with two hole openings opposed to one another in an axial direction and form openings of a mounting hole, two axle pins spaced apart axially, extend in axial direction and engage in the mounting hole through the hole openings, and a chassis component supported at axial end portions of the axle pins to be swivelable relative to the steering knuckle. A first contact area at the hole openings has a conical inner circumferential surface. The conical inner circumferential surfaces of the first contact areas narrow in diameter toward one another in axial direction. The axle pins have a second contact area with a conical outer circumferential surface that narrow in diameter toward one another in axial direction and contact the conical inner circumferential surfaces of the first contact areas.
