Abstract
A front-wheel suspension is disclosed, especially for two-wheeled vehicles such as motor-assisted bicycles and motor-scooters, in which the usual swinging front fork is replaced by a single goose-necked stiff arm capable of overhangingly carrying the vehicle front wheel and pivotally connected, at its bottom end, to the wheel axle by the intermediary of a swingable link. A springing and shock-absorbing telescopable member is pivotally connected, at its top, to an intermediate portion of said arm and, at its bottom, to the wheel axle. A brake device is rigidly connected to the shock-assembly member. The construction is much simplified over the prior art and the costs are significantly reduced: a favorable distribution of the stresses throughout the entire system is also achieved.
