Description
Technical field
The present invention relates to a kind of flywheel, the variable flywheel of more particularly to a kind of rotary inertia and the sportswear with the flywheel
Put.
Background technology
Flywheel is mounted in the colyliform accumulator having compared with large rotating inertia on engine crankshaft, when engine speed increases
Gao Shi, the kinetic energy increase of flywheel, gets up energy storage or saving；When engine speed is reduced, flywheel energy is reduced, and energy is discharged
Out, it can be used for reducing the velocity perturbation of machine operation process, the portion of energy of engine working stroke can be stored
Come, to overcome the resistance of other strokes, make bent axle Rotating with Uniform.
Existing flywheel is generally fixed disk-shaped structure, generally selects the weight of middle setting flywheel, and its rotary inertia is fixed not
Become, the rotary inertia of flywheel is bigger, and its energy storage capability is stronger, beneficial to engine even running, but needs to carry in start-up course
For larger staring torque, that is, need to consume more energy overcome flywheel it is used can, reduce the flexibility of engine.
Therefore, it is necessary to a kind of variable flywheel of rotary inertia, inactive state rotary inertia is small so as to reaching the mesh easily started
, as rotating speed rises rotary inertia increase so as to reach the purpose of energy storage, after the end that releases energy and original state is returned to,
So as to solve the problems, such as that flywheel is not easy to start.
The content of the invention
It is an object of the invention to overcome in the prior art, engine even running is realized, it is necessary to which the rotation of flywheel is used to
Measure it is larger, the problem of needing to provide larger staring torque during startup, there is provided the variable flywheel of a kind of rotary inertia and with this
The telecontrol equipment of flywheel, rotary inertia is small so as to reach the purpose easily started when the flywheel remains static, with rotating speed
