  • Patent number: 7293619
    Abstract: A front-wheel motor powered golf trolley comprised of a compact backward tricycle-wheel arrangement and a lightweight stiff open truss chassis. Left and right front wheel assemblies, driven by common drive axle, motorized through silent motor speed reduction, pull the trolley in an easily guided walk-along fashion. The driven front wheels are compliantly isolated from the chassis by sprung front axle support arms. Trolley stance stabilization and steering are by an independently sprung rear wheel/pivot assembly, the pivot being located between the front drive and rear wheel axles. A steering handle is the user-guiding interface and location for all hand operated controls. Upper and lower golf bag supports fold out from the chassis. Stow-ability is compact and without bulkiness. This trolley is adaptable to remote control of power, steering, and braking functions. The trolley also accommodates multiple other user conveniences.
