250, each baffle 250 is fixedly arranged on wheel disc 210, and every group of baffle 250 is respectively formed the slideway for guiding mass block 230.
Such setting realizes effective guiding to mass block 230, and simple in structure, and cost is relatively low.
In addition, in the present embodiment, the flywheel 200 can also include limiting plate for being limited to mass block 230 (in figure not
It shows).Specifically, limiting plate is fixed on every group of baffle 250, to be formed with every group of baffle 250 for guiding mass block 230
Close slideway.The setting of limiting plate so that mass block 230 can steadily be fitted in 210 apparent motion of wheel disc, motion path compared with
It is good, further achieve the purpose that 200 high-efficiency energy-storage of flywheel.
Please continue to refer to Fig. 2 and Fig. 3, in the present embodiment, each mass block 230 is uniformly distributed along the circumferential annular of wheel disc 210.In this way
Setting so that the Energy distribution in 210 thermal energy storage process of wheel disc is more uniform, and avoid causes because of unbalance loading to a certain extent
Non-uniform mass phenomenon, to ensure that reliability of the flywheel 200 to 100 passing power of engine.
In addition, in the present embodiment, mass block 230 can be spherical.Such setting reduces mass block 230 and wheel
The contact area of disk 210 thus greatly reduces the contact friction of mass block 230 and wheel disc 210 in 200 rotation process of flywheel
Power, and collision between the two is reduced, the energy expenditure in 200 thermal energy storage process of flywheel is further reduced, energy storage is improved
Efficiency.
