Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further described:

Fig. 1 is structural representation of the present utility model.

Embodiment

Fig. 1 is structural representation of the present utility model, as shown in the figure: inner equilibrium flywheel of the present utility model, comprises flywheel body 1, becomes inertia slide block 2 and inner equilibrium rotating disk 3; Described change inertia slide block 2 is at least two and wheel body 1 rotating shaft of being diversion and is evenly arranged, and each becomes inertia slide block 2 and all radially slides and be connected in flywheel body 1; Inner equilibrium rotating disk 3 is connected with flywheel body 1 coaxial rotation; Described inner equilibrium rotating disk 3 is slidably matched by plane slideway 4 with change inertia slide block 2; Described plane slideway 4 makes it in a certain angle with respective slide glide direction along rotating disk circumferencial direction deflection; In Fig. 1, the A place direction of arrow is turning to of flywheel body 1, and plane slideway 4 is sliding groove structure, is located on inner equilibrium rotating disk 3, becomes corresponding flat slideway 4 on inertia slide block 2 and is fixed with the slip guide block for being slidably matched with plane slideway 4; Each becomes inertia slide block 2 along the 1 place planar slide of flywheel body, plane slideway 4 and flywheel body 1 place plane parallel, and plane slideway 4 can be that linear ramp can be also curve slideway; When plane slideway 4 is curve slideway, be designed to inside and outside two end part and pointed to inner equilibrium rotating disk 3 sense of rotation, middle part is to the cambered way of the reverse protrusion of inner equilibrium rotating disk 3 sense of rotation, that can when flywheel body 1 accelerates to rotate, utilize inner equilibrium rotating disk 3 is used to can hinder the 2 radially outwards slips of change inertia slide block, avoid whole Rotary Inertia of Flywheel to become large, realize and in the short time, complete acceleration; At flywheel body 1, slow down while rotating, can utilize inner equilibrium rotating disk 3 be used to can promote radially inwardly slip of change inertia slide block 2, the rotary inertia of whole flywheel is diminished, realize and in the short time, complete deceleration.

In the present embodiment, described plane slideway 4 and the 2 corresponding settings one by one of change inertia slide block; The reverse deflection that plane slideway 4 radially turns to inner equilibrium rotating disk 3 from inside to outside along inner equilibrium rotating disk 3; While making to become the 2 radially outwards slip of inertia slide block, inner equilibrium rotating disk 3 need to surmount in the rotation of flywheel body 1, when change inertia slide block 2 radially inwardly slides, inner equilibrium rotating disk 3 need to lag behind the rotation of flywheel body 1, therefore at flywheel body 1, accelerate in rotation process, because the effect of inertia of inner equilibrium rotating disk 3 can be to the certain obstruction of change inertia slide block 2 radially outwards slip formation, and then the rotary inertia change that hinders whole flywheel is large, realizes flywheel body and completes speed-raising in 1 short time.

In the present embodiment, when change inertia slide block 2 radially slides from inside to outside along flywheel body 1, plane slideway 4 becomes large gradually with the angle of phase strain inertia slide block 2 glide directions; This angle minimum value is not more than 45 degree, maximum value is not more than 90 degree and is not less than 60 degree, elastic member can be installed between inner equilibrium rotating disk 3 and flywheel body 1 and provide reverse elastic force for inner equilibrium rotating disk 3, therefore can under reverse resilient force, by inner equilibrium rotating disk 3, promote to become inertia slide block 2 returning quicklies, reduce the rotary inertia of whole flywheel, realize and in the short time, complete deceleration.

In the present embodiment, also comprise that the inner equilibrium rotating disk 3 that is used to being connected between flywheel body 1 and inner equilibrium rotating disk 3 provides the elastic component 5 of reverse elastic force, can under reverse resilient force, by inner equilibrium rotating disk 3, effectively control the motion that becomes inertia slide block 2, make the rotary inertia of whole flywheel carry out adaptations according to engine crankshaft rotating speed.

In the present embodiment, described elastic component 5 is the torsion spring with flywheel body 1 and the coaxial setting of inner equilibrium rotating disk 3.

Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
