"Bath cushioning for Kxafträdera, scooters, etc.« "

The invention relates to a suspension system which is intended to be used in particular for the rear wheel of a motorcycle, a motor scooter or the like and which aims to reduce the conveying performance to the different loads, such as those caused by a load on the luggage rack or by adding a sidecar to be able to adapt.

It is büktinnt that Hinterradabfederung vox for this purpose by using a Hcuptfeder and a Zusatzfedsr; zuiieii; nn In a bekynnten> usf ührungsf orally is in this case the auxiliary spring disposed within the main spring lying, and can be switched in parallel for multiple loading of Hcuptfeder "ground. The device is designed in such a way that the additional spring penetrates the upper abutment of the main spring and is attached to a bell adjustably mounted on this abutment. Pie bell is provided with beonet-shaped slots at different heights into which pins connected to the abutment mentioned engage. Purchasing parts of the bell, the additional spring comes to rest on the lower abutment of the main spring, so that now both springs are connected in parallel and the overall

The disadvantages of well-known Cadab suspension results in particular from their open Construction that requires an elevated position from the lack of securing of the feathers against lateral buckling, as a result of which the suspension becomes unusable prematurely, and of the '' expenditure for installing it Power wheel.
