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).

摘要： A coupling is provided for connecting a two-track trailer having at least one drawbar, to a non-motorized vehicle, or to a vehicle having an auxiliary drive, particularly a bicycle. The coupling has two interacting coupling parts releasable from one another and respectively connectable to the vehicle and to the drawbar. The coupling has a bolt having a cylindrical shell surface and a bushing or bolt guide, plugged onto the bolt and engaging at least partially around the bolt, as interacting coupling parts. The bushing or bolt guide has at least one opening for insertion of the bolt. The interconnected coupling parts are rotatable relative to one another about their common longitudinal axis and act as a rotary joint with one degree of freedom. The coupling parts have a lock to securely connect them together. On the drawbar, further joints impart the coupling with at least two further degrees of freedom.
