Abstract
A braking device including a chamber rotatably mounted on an axle, the chamber defining an inner cavity, a disc mounted on the axle in the inner cavity, the disc having opposing surfaces extending away from the axle, and a pourable material disposed in the inner cavity such that rotation of the chamber imparts a centrifugal force to the material, causing the material to be wedged between an inner surface of the inner cavity and the opposing faces so as to apply a braking force to the disc.
Claims12
A braking device comprising:
- a chamber rotatably mounted on an axle, said chamber defining an inner cavity;
- a disc mounted on said axle in said inner cavity, said disc having opposing surfaces extending away from said axle;
- and
- a solid pourable material disposed in said inner cavity such that rotation of said chamber imparts a centrifugal force to said material, causing said material to be wedged between an inner surface of said inner cavity and said opposing surfaces so as to apply a braking force to said disc;
- wherein said pourable material is selected from a group consisting of:
- sand, powdered material and granulated material.

A braking device comprising:
- a chamber rotatably mounted on an axle, said chamber defining an inner cavity;
- a disc mounted on said axle in said inner cavity, said disc having opposing surfaces extending away from said axle;
- and
- a wedge disposed in said inner cavity such that rotation of said chamber imparts a centrifugal force to said wedge, causing said wedge to be wedged between an inner surface of said inner cavity and said opposing surfaces so as to apply a braking force to said disc.
