Training machine with flywheel

Abstract

A flywheel is applied to a training machine including a wheel and a driving mechanism. The wheel is used for storing rotation energy while it is driven to rotate, and the driving mechanism is used for driving the wheel to rotate. The wheel has a hollowed space at least partially filled with a weighted material, at least one metal piece fixed at a periphery of the wheel, and a magnets arranged at the outside of the wheel. A damping of the wheel is changed by adjusting the distance between the metal piece and the plurality of magnets.

What is claimed is: 
     
         1 . A flywheel applied to a training machine, including:
 a wheel, for storing rotation energy while it is driven to rotate; and   a driving mechanism, for driving the wheel to rotate;   wherein the wheel comprises:
 a hollowed space at least partially filled with a weighted material; 
 at least one metal piece fixed at a periphery of the wheel; and 
 a plurality of magnets arranged at the outside of the wheel; 
 wherein a damping of the wheel is changed by adjusting a distance between the metal piece and the plurality of magnets. 
   
     
     
         2 . The flywheel as set forth in  claim 1 , wherein the weighted material is a non-metal material. 
     
     
         3 . The flywheel as set forth in  claim 2 , wherein the non-metal material comprises cement or concrete. 
     
     
         4 . The flywheel as set forth in  claim 1 , wherein the metal piece is made of aluminum. 
     
     
         5 . The flywheel as set forth in  claim 1 , wherein the metal piece is ring-shaped. 
     
     
         6 . The flywheel as set forth in  claim 1 , wherein the flywheel further comprises a plurality of vanes spaced apart between the metal piece and the wheel, and when the wheel is driven to rotate the vanes rotate as well so as to generate an air turbulence. 
     
     
         7 . The flywheel as set forth in  claim 1 , wherein the driving mechanism comprises:
 a bearing assembly comprising a one-way bearing to limit the rotating direction of the wheel;   a belt wound on the bearing assembly and configured for being pulled to drive the wheel to rotate; and   a returning mechanism for drawing back the belt to its original position when a force for pulling the belt out is cancelled or released.   
     
     
         8 . The flywheel as set forth in  claim 7 , wherein the returning mechanism comprises a reposition spring for drawing back the belt to its original position when the force for pulling the belt out is cancelled or released. 
     
     
         9 . The flywheel as set forth in  claim 8 , wherein the reposition spring is a vortex spring. 
     
     
         10 . A rowing simulation machine, comprising:
 a flywheel;   a driving mechanism;   a base mechanism, for providing support to the flywheel;   a handle connected to the driving mechanism;   a wheel for storing rotation energy when driven to rotate by the driving mechanism;   a hollowed space in the wheel, the hollowed space being at least partially filled with a weighted material;   at least one metal piece fixed at a periphery of the wheel; and   a plurality of magnets arranged at the outside of the wheel;   wherein a damping of the wheel is changed by adjusting the distance between the metal piece and the plurality of magnets.   
     
     
         11 . The rowing simulation machine as set forth in  claim 10 , wherein the weighted material is a non-metal material. 
     
     
         12 . The rowing simulation machine as set forth in  claim 11 , wherein the non-metal material comprises cement or concrete. 
     
     
         13 . The rowing simulation machine as set forth in  claim 10 , wherein the metal piece is made of aluminum. 
     
     
         14 . The rowing simulation machine as set forth in  claim 10 , wherein the metal piece is ring-shaped. 
     
     
         15 . The rowing simulation machine as set forth in  claim 1 , wherein the wheel comprises a plurality of vanes spaced apart between the metal piece and the wheel, whereby when the wheel is driven to rotate the vanes rotate as well to generate an air turbulence. 
     
     
         16 . The rowing simulation machine as set forth in  claim 10 , wherein the driving mechanism comprises:
 a bearing assembly comprising a one-way bearing to limit the rotating direction of the wheel;   a belt being wound on the bearing assembly and being pulled to drive the wheel to rotate; and   a returning mechanism for drawing back the belt to its original position when a force for pulling the belt out is cancelled or released.   
     
     
         17 . The rowing simulation machine as set forth in  claim 16 , wherein the returning mechanism comprises a reposition spring for drawing back the belt to its original position when the force for pulling the belt out is cancelled or released. 
     
     
         18 . The rowing simulation machine as set forth in  claim 17 , wherein the reposition spring is a vortex spring. 
     
     
         19 . The rowing simulation machine as set forth in  claim 16 , wherein the flywheel comprises the wheel and the driving mechanism.
