Variable rolling resistance wheel for rolling vehicle
First Claim
Patent Images
1. A variable resistance wheel for a rolling vehicle, and the vehicle has one or more shafts for mounting wheels thereon, wherein the wheel comprises;
- a rim having a hole through its center for mounting the wheel on a shaft of the vehicle, the rim having at least one bearing that is mounted in the center mounting hole and the bearing permits the rim to rotate on the shaft;
a tire mounted on the rim furthest from the hole through the center of the rim;
a seal mounted in and concentric with the hole through the center of the rim and the shaft passes through the seal, the seal pressing against the shaft, and the seal has a recess that forms a chamber around the shaft when the seal is pressing against the shaft; and
a viscous grease that is contained in the chamber and contacts the shaft;
wherein the grease creates a kinematic shear action resistance to the rotation of the wheel about the shaft, and the grease is changed to change the kinematic shear action resistance to the rotation of the wheel.

Abstract
A wheel for an in-line skate or other wheeled vehicle is disclosed that may be modified to alter the rolling resistance of the wheel. The wheel may be disassembled to change a tire on the outer surface of the wheel to one made of a harder or softer material, and to insert or change a grease of a chosen viscosity into a chamber inside the wheel. The two changes may be utilized singly or collectively to help set the rolling resistance of the wheel. The wheel may be retrofit onto existing in-line roller skates.

12. A variable resistance wheel for a wheeled vehicle, and the vehicle has one or more shafts for mounting variable resistance wheels thereon, wherein the wheel comprises;
-
a rim having a hole through its center used for mounting the wheel on a shaft of the vehicle, the rim having at least one bearing that is mounted in the center mounting hole and the at least one bearing assists the rim to rotate on the shaft; a tire mounted on the rim; a seal mounted in and concentric with the hole through the center of the rim and a shaft passes through the seal and the at least one bearing when the wheel is mounted on the vehicle, wherein the seal presses against the shaft, and wherein the seal has a recess that forms a chamber around the shaft when the seal is pressing against the shaft; and a viscous grease that fills the chamber and contacts the shaft; wherein the grease creates a kinematic shear action resistance to the rotation of the wheel about the shaft, and the grease is changed to change the kinematic shear action resistance to the rotation of the wheel. - View Dependent Claims (13)
