Description
Technical field
The utility model relates to the sports equipment field, is meant a kind of sports equipment that is installed on especially, has splendid economy, and the magnetic control flywheel of the sports equipment of magnetic control usefulness.
Background technology
The magnetic control flywheel is at treadmill, exercycle, the car of marking time ... or the like extensively used in the sports equipment, utilize the gap of flywheel periphery and magnet to change the effect that reaches in good time adjustment damping, with in response to the demand of user to motion.
For example shown in Figure 1, for known outside exercycle is equipped with suction formula magnetic control flywheel, this exercycle is pivoted with the flywheel 12 that cast iron quality is made in the fork arm 11 of support body 10, make flywheel 12 peripheries have certain magnetic conductivity, and these flywheel 12 periphery frames are covered with layer of aluminum ratch face 13, and this flywheel 12 can be connected by a belt 14 with a drive 16 that is driven for pedal 15, and the magnetic receiver that is covered with an arcuation 17 of support body 10 weekly interval outside wheel face 13, these magnetic receiver 17 inner peripheral surfaces then are provided with magnet 18, the user can be by adjusting magnetic receiver 17 angles, make magnet 18 move closer to or away from flywheel 12 peripheries, get so that this magnet 18, the distance that flywheel is 12 produces obvious size variation with the magnetic flux holdback force, to reach the motor function that adjusts the magnetic control load.
Fig. 2 discloses other and plants internal-suction type magnetic control flywheel, its mainly flywheel 12 end face one concentric be equipped with a wheel face 121, one non-rotary positioning disk 19 then is installed in wheel face 121, positioning disk 19 is provided with two semicircular arc magnetic receivers 17 in interior all positions of wheel face 121 correspondence, make that two magnetic receivers, 17 1 ends are hubbed at positioning disk 19, in addition ora terminalis then connects and adjusts line 191, these two magnetic receivers, 17 outer peripheral faces then are provided with magnet 18, make two magnetic receivers 17 can be adjusted moving of line 191 controls, make magnet 18 near or away from wheel face 121, and then reach and adjust flywheel 12 loads.
Fig. 1,2 described outer suction formula flywheels, internal-suction type flywheel are all commonly used the existing structure form of " integrally casting flywheel " for fear of these, and derive as after shortcoming:
1. because flywheel 12 is one-body molded with a large amount of cast irons, in today that the former material cost of metal hits new peak repeatly, the material cost of this flywheel 12 produces great burden to relative manufacturer, is difficult to meet the requirement of economical production, and this is that one cast iron flywheel 12 has part to be overcome now.And this heavy weight flywheel because driving torque is also relatively large, so that flywheel 12 to be hubbed at the Structural Design Requirement of support body 10 higher, thus, the cost of its structure that is pivoted can't further reduce.
Moreover, the magnet 18 of its magnetic receiver 17 is the state of maintaining static, so under permanent magnetic control load, magnet 18 can't fully dispel the heat, and just can cause magnetic control usefulness to descend gradually thus, cause it and can't keep certain damping.
Edge is, because commonly use structure above-mentioned improper part arranged, and the design people actively makes great efforts research, through repeatedly improvement, develops the utility model that true tool practical effect finally.
