Abstract

An improved form of three-wheeled vehicle of the type having a front wheel arranged in the longitudinal plane of symmetry of the vehicle and a pair of rear wheels arranged symmetrically with respect to the vehicle plane. The pivot joint interconnecting the front and rear frames of the vehicle has a turning axis offset from the vehicle plane to that side of the vehicle on which the driving rear wheel is arranged and extending in a direction inclined laterally outwardly from rear to front of the vehicle. Such pivot arrangement is highly effective to improve the driving stability of three-wheeled vehicles of the type concerned, without involving any structural complication or increase in cost of production.
