Abstract
The stepless speed variator with mobile transmission medium includes two conic transmission wheels and two annuluses separately on two conic transmission wheels to realize transmission. Under the actions of friction force and meshed gears, the stepless speed variator completes mechanical transmission. Shifting the annulus combination axially along the conic shaft will alter the radii of the transmission wheels and change the transmission ratio so as to obtain continuous stepless speed variation. The present invention is used in transmission machine and vehicle.
Description
Technical field
The present invention is applied to mechanical transmission, a kind of stepless speed changes devices of its velocity ratio continuous variable.
Background technique
At present, main in the world 2 kinds of stepless speed variators that adopt are: a kind of stepless speed variator (being called for short CVT), and 2 taper drive wheels utilize belt or steel chain transmission power, and structure is comparatively complicated, and can not transmit high-power, comparatively universal; A kind of unlimited speed changing type mechanical stepless transmission (being called for short IVT) that is called is in the popularization stage on probation.
Summary of the invention
Stepless speed variator with mobile transmission medium.2 taper drive wheels are arranged in parallel, and under the effect of the frictional force of intermediary, realize the transmission of power, make to transmit media and move in the axial direction, obtain continuous velocity transformation, and are simple in structure.
Description of drawings
Fig. 1 is the stereogram of stepless speed variator with mobile transmission medium;
Fig. 2 is the elevation of stepless speed variator with mobile transmission medium;
Fig. 3 is the axial section of stepless speed variator with mobile transmission medium;
Fig. 4 is the transverse cross-sectional view of stepless speed variator with mobile transmission medium.
Among the figure: 1, active taper drive wheel; 2, passive taper drive wheel; 3, active gear ring; 4, passive gear ring.
Initiatively taper drive wheel (1) and passive taper drive wheel (2), be that a pair of size is identical, direction on the contrary, a pair of drive wheel that is arranged in parallel.Initiatively gear ring (3) and passive gear ring (4), interior sky is taper, and slope equates that with drive wheel double-layer structural, the outer gear teeth are rigidity, internal layer is the flexible friction sheet, is the media of active taper drive wheel (1), passive taper drive wheel (2) frictional contact surface.
Embodiment
Initiatively taper drive wheel (1), passive taper drive wheel (2) are arranged in parallel, and initiatively gear ring (3), passive gear ring (4) are enclosed within respectively on active taper drive wheel (1) and the passive taper drive wheel (2), and gear engagement constitutes combination.Adjust two distance between shafts, spacing is dwindled, increase the initiatively pressure between taper drive wheel (1), passive taper drive wheel (2), active gear ring (3), passive gear ring (4), initiatively the frictional force between taper drive wheel (1) and active gear ring (3), passive taper drive wheel (2) and passive gear ring (4) increases.When initiatively taper drive wheel (1) rotates,, give passive taper drive wheel (4) transmission of power by the effect of gear ring media frictional force and gear meshing power.
Utilize machine power or hydraulic power, promote to endwisely slip on the conical surface that initiatively gear ring (3) and passive gear ring (4) be combined in active taper drive wheel (1), passive taper drive wheel (2), because the contact position of drive wheel recurs change, just continuous variation takes place in the radius of drive wheel, thereby obtains the speed continuous transformation.As Fig. 3: the gear ring combination is moved to the speed-change process on top by the dotted line position of bottom.
Claims (2)
1, a kind of mechanical transmission.2 taper drive wheels, 2 gear rings, interior sky are taper, and slope is identical with the taper drive wheel, and 2 taper drive wheels are arranged in parallel, and 2 gear rings are enclosed within respectively on 2 taper drive wheels, and composite structure is the media of transmission.By media, under the effect of frictional force and gear meshing power, realize transmission.The gear ring combination endwisely slips along the conical surface, continuously changes the radius of drive wheel, realizes continuously changing of velocity ratio, obtains continuous stepless difference speed change.
2, a kind of mechanical transmission.Be extended down to 2 taper drive wheels outward, parallel to an axis is arranged, and the conical surface is apart from there being certain intervals, and the middle media that inserts is realized transmission.Media is endwisely slipped along the conical surface, and the point of contact of conical surface transmission changes vertically, realizes that the radius of drive wheel continuously changes, and obtains continuous stepless difference speed change.
