RESISTANCE REGULATING DEVICE FOR WHEEL OF TRAINING MACHINE
First Claim
Patent Images
1. A resistance adjusting device used for a wheel of a training machine, comprising:
- a stationary mechanism being fixed with the training machine;
a rotary mechanism being pivoted to the stationary mechanism by a pivot and comprising a plurality of magnets for providing a resistance to the wheel;
a link member pivotally connecting to a first end of the rotary mechanism;
a motor being connected with the link member;
a screw having a first end connected to the motor and being rotatable by the motor; and
a nut pivotally connecting with the stationary mechanism, a second end of the screw passing through the nut and being movably engaged with the inner thread of the nut;
whereby the motor drives the screw to rotate, causing the rotary mechanism to rotate about the pivot, and thereby changing a distance between the plurality of magnets and the wheel, so as to increase or decrease the resistance.

Abstract
A resistance regulating device for a wheel of a training device is disclosed. The resistance regulating device comprises a rotary mechanism pivotally connected with a stationary mechanism and a motor with other components to rotate the rotary mechanism and hence a distance between magnets of the rotary mechanism and the wheel is changed. In addition, an optical detection device may be used to detect and define a minimum resistance and a maximum resistance and hence to adjust a resistance in a stepless manner An emergency brake mechanism may be further employed.
