Description

technical field [0001] The invention relates to an adjustable resistance system and its device. Background technique [0002] For the current exercise device or fitness device, in addition to providing users with simple walking and stepping on it, it can also provide operation modes such as adjusting walking speed and changing stepping weight to improve the effect of exercise according to user requirements. When the device is changing the operating mode, it is mainly by changing the resistance value of the resistance component in the device, and the common operating principles can be roughly classified into mechanical methods, electromagnetic resistance methods, eddy current braking methods, and permanent magnet attraction methods. [0003] However, in terms of mechanical means, since the brake shoes or pads are used as resistance components to generate resistance through friction, noise will be generated under poor lubrication conditions, and the resistance components are e...

Problems solved by technology

[0003] However, in terms of mechanical means, because it uses brake shoes or pads as resistance components to generate resistance through friction, it will generate noise under poor lubrication conditions, and the resistance components are easy to wear out after long-term use

In terms of electromagnetic resistance, the electromagnetic field can be activated after the power is introduced from the outside, and different resistances can be generated by changing the strength of the electromagnetic field. Although this method does not have the problem of noise or component wear, the frequently changing electromagnetic field requires an external application. power consumption

For the eddy current braking method, which is similar to the electromagnetic resistance method, an external power supply is required to generate eddy current to further generate reluctance. Although eddy current can control the change of reluctance more accurately, eddy current will generate high temperature. , so that the heat dissipation efficiency must be considered in the design of the device

For the permanent magnet attraction method, since this method uses the distance between the permanent magnet and the flywheel (flywheel) to change the resistance value, the main disadvantage of this method is that the flywheel must be made of magnetically permeable materials, and in practical applications, The distance between the permanent magnet and the flywheel is difficult to keep fixed
