摘要

A wheel suspension is provided for a non-motorized vehicle, in particular a pram or a bicycle trailer designed to transport children, which features a chassis (1) and at least two wheels (8), which are each mounted on a wheel swing arm (11, 15). For each wheel swing arm (11, 15) at least one elastic element (21) is provided, whereby the wheel swing arm (11, 15) supports itself via the chassis (1). In order to provide a wheel suspension of this kind which is based on a simple construction and enables an optimum level of suspension and shock-absorption for the non-motorized vehicle: (a.) the elastic element (21) is made of at least one dimensionally stable flexible polyurethane foam material, and/or (b.) both wheel swing arms (11, 15) protrude laterally over the chassis (1) and can be pivoted past a lateral frame section (3, 4) of the chassis (1).
