Abstract
The utility model provides a dipyramidal surface driving wheel used to substitute a ring-typed or a chain driving element with low driving efficiency and small transferring torque in a stepless speed change device for vehicles. Pressure is applied axially to the dipyramidal surface driving wheel between a driving pyramid wheel on the driving axis and an output pyramid wheel on an output axis via the driving pyramid wheel on the driving axis and the output pyramid wheel on the output axis. When the transferred pressure of any driving pyramid wheel or output pyramid wheel is larger than the other, the driving axis where the dipyramidal surface driving wheel is positioned displaces in parallel to one part with smaller pressure, so as to change a contact radius meshed by the dipyramidal surface driving pyramid wheel and the output pyramid wheel to realize continuous change of the driving rate. Because the dipyramidal surface driving wheel has larger compressive strength, the utility model not only can carry out large torque transference in the stepless gear process, but also can not be damaged easily.
Description
Technical field
The utility model relates to the torque drive part in a kind of automative stepless speed-variation device.
Background technique
At present, the stepless speed changes devices that supporting automobile uses, mainly comprise speed ratio variator, ring-like metal tape or the basic elements of character such as chain, servomechanism, the speed ratio variator comprise on the driving shaft one can axially movable cone pulley and one fixedly on cone pulley and the output shaft can axially movable cone pulley and one fixedly cone pulley constitute, servomechanism is controlled its movable cone pulley respectively and is moved axially on axle.During work, move axially, change initiatively wheels and the conical surface of driven wheels and the spacing of the conical surface, adjust the radius of clean-up of ring-like metal tape engagement, thereby change velocity ratio, realize successional stepless change by movable cone pulley.
No matter be torque transfer member such as ring-like metal tape or chain, in the moment of torsion transmittance process, to bear on the one hand the movable cone pulley and the fixing pressure of cone pulley, pulling force also will be born in the aspect in addition, because the conditionality of structure itself, its resistance to compression, tension, etc. mechanical property seem comparatively weak, therefore, it can not carry out big moment of torsion transmission.
The model utility content
The purpose of this utility model will provide in a kind of automative stepless speed-variation device exactly, substitute ring-like metal tape and the chain transmission part that has now in the stepless speed changes devices with a kind of simple in structure, not easily damaged driving component, realize the high pulling torque transmission under the stepless change condition.
For achieving the above object, the utility model adopts following technological scheme: the utility model comprises driving shaft, cooperate with driving shaft connect two initiatively cone pulleys, output shaft, cooperates two of connecting to export cone pulleys with output shaft, two active cone pulleys respectively have a conical surface; Two output cone pulleys respectively have a conical surface.The axis of driving shaft and output shaft is parallel to each other.Between driving shaft and output shaft, transmission shaft is arranged, a bipyramid face drive wheel is arranged on the transmission shaft, two conical surfaces are arranged on the bipyramid face drive wheel.Consistent and the frictional fit of tapering of two conical surfaces on the bipyramid face drive wheel and the conical surface of pairing active cone pulley and output cone pulley.In order to guarantee bipyramid face drive wheel transmitting large torque, the axis of driving shaft, output shaft and transmission shaft is in same plane and is parallel to each other.
During work, adjust two initiatively cone pulley and two conical surface applied pressures of exporting cone pulley to bipyramid face drive wheel by servomechanism, when a side applied pressure during greater than opposite side pressure, transmission shaft with bipyramid face drive wheel to the more weak side parallel shift of pressure, like this, initiatively cone pulley and output cone pulley and bipyramid face drive wheel joggleword radius change, and have promptly changed velocity ratio.Because initiatively the radius of clean-up of cone pulley and output cone pulley can realize continuous adjusting, thereby realizes stepless change.
Substitute ring-like metal tape or chain with bipyramid face drive wheel and realize high pulling torque transmission in the stepless change process of automobile.Compare with chain with ring-like metal tape, bipyramid face drive wheel simple structure, anti-extruding should not be damaged.Therefore, the utility model can be realized the high pulling torque transmission in the stepless change process.
Description of drawings
Fig. 1 is the utility model embodiment 1 structural representation.
Reference character:
1 driving shaft, 2 output shafts, 3 output cone pulleys, 4 conical surfaces
5 conical surfaces, 6 output cone pulleys, 7 transmission shafts, 8 conical surfaces
9 active cone pulleys, 10 conical surfaces, 11 conical surfaces 12 are cone pulleys initiatively
13 conical surfaces, 14 bipyramid face drive wheels
Embodiment
With reference to Fig. 1.Between driving shaft 1 and output shaft 2, transmission shaft 7 is arranged.Bipyramid face drive wheel 14 is arranged on transmission shaft 7.Two conical surfaces 8,13 of bipyramid face drive wheel respectively with driving shaft on two initiatively the conical surface separately 10,11 of cone pulleys 9,12 and the conical surfaces 5,4 of two output cone pulleys 6,3 on the output shaft are meshed.Bipyramid face drive wheel, initiatively cone pulley is consistent with the tapering of the pairing conical surface of output cone pulley, the conical surface of bipyramid face drive wheel both sides can be processed into different taperings, and consistent with the tapering of the conical surface of the active cone pulley of corresponding friction engagement, output cone pulley.Frictional fit between them is the line contact.Under the effect of servomechanism, initiatively cone pulley and output cone pulley to conical surface power axle to applying extruding force, when active cone pulley applied pressure greater than output cone pulley pressure the time, maybe when output cone pulley applied pressure during greater than the pressure of active cone pulley, bipyramid face drive wheel and transmission shaft will parallel shifts between driving shaft and output shaft.Bipyramid face drive wheel changes with the contact radius of the initiatively engagement of cone pulley, output cone pulley, thereby the velocity ratio of driving shaft and output shaft is changed.Because the radius of clean-up of driving wheel and follower can realize continuous adjusting, thereby realize stepless change.The structures shape of bipyramid face drive wheel its high compression strength is arranged, thereby can transmit bigger moment of torsion.
