Abstract

A spring seat body for connection to a rigid axle of a motor vehicle, including an upper spring seat surface, a lower seat surface, lateral edge surfaces which lie between the spring seat surface and the lower seat surface, and holding means for holding tensioning means for fastening at least one spring to the spring seat body. The lateral edge surfaces include a first edge surface and a second edge surface which face away from one another and, in the mounted state of the spring seat body on the rigid axle, run transversely with respect to the rigid axle, the first edge surface, in the mounted state of the spring seat body on the rigid axle, lying closer to an end of the rigid axle which bears a vehicle wheel than the second edge surface, and the first edge surface having an edge course which, in the mounted state of the spring seat body on the rigid axle, lies in overlap with the rigid axle. In order for the spring seat body to offer improved robustness, in particular increased fatigue strength in its connection to a generic rigid axle and thereby enable a reduction in the overall weight of the rigid axle, the invention provides that said edge course, viewed from above, is at least partially formed as an outwardly projecting, preferably convex edge course, the apex or vertex lies in a region of the first edge surface which runs along a central length range of the upper spring seat surface running transversely to the rigid axle, said central length range being less than one third, preferably less than one quarter, particularly preferably less than one fifth of the length of the upper spring seat surface. In particular, the invention relates to a rigid axle for a motor vehicle, in particular a utility vehicle, with such a spring seat body.
