Abstract: A swivel wheel assembly includes a wheel axle, and a vehicle wheel rotatably mounted on the wheel axle. A shock-absorbing wheel fork is secured to opposite ends of the wheel axle and includes first and second elongated spaced-apart support arms. A pivot pin extends through pin openings formed with proximal ends of the first and second support arms. A base is carried by the pivot pin, and is adapted for pivoting movement about an axis defined by the pivot pin. An adjustable shock absorber dampens pivoting movement of the base relative to the vehicle wheel, thereby absorbing the energy of sudden shocks to the vehicle wheel during use.

Abstract: A swivel wheel assembly includes a wheel axle, and a vehicle wheel rotatably mounted on the wheel axle. A shock-absorbing wheel fork is secured to opposite ends of the wheel axle. The wheel fork includes first and second elongated spaced-apart support arms located on opposite sides of the vehicle wheel. The support arms have respective distal and proximal ends. The distal ends define respective axle openings receiving the wheel axle. The proximal ends extend beyond a periphery of the vehicle wheel and define respective pin openings. A pivot pin extends through the pin openings formed with proximal ends of the first and second support arms. A base is carried by the pivot pin, and is adapted for pivoting movement about an axis defined by the pivot pin. A vertical swivel shaft is mounted on the base, and is adapted for connecting to an underframe of a vehicle to provide swivel movement of the vehicle wheel about an axis defined by the swivel shaft.
