Though above-mentioned upper support parts 67 and lower support parts 69 can support this ring 25 with the mode of carrier ring 25; And move integratedly with moving member 63; Ring 25 is moved vertically; But upper support parts and lower support parts 67,69 constitute; The upstream side of the sense of rotation of drawing at ring 25 quilts and the contacting part of two friction wheels 22,23 is so that supporting ring 25 and the mode that limits (clamping) in the axial direction link from the two sides, and allows move axially (vibration) of ring 25 in the sense of rotation downstream side that is forced out from above-mentioned contacting part.Therefore; No matter friction wheel carries out positive rotation or despining; Ring 25 is all supported by any up and down side's who is positioned at its upstream side support unit 67 or 69 modes with clamping; Be positioned accordingly with the position mobile or that stop based on moving member 63, the opposing party's of any up and down side support unit 69 or 67 allows to be in this moment above-mentioned vibration of moving the ring 25 in perhaps stopping, and ring 25 is supported by self-discipline ground.
Though encircle 25 utilize to limit axially movable rotation upstream side support unit 67 or 69 confirm its tilt angle tilt angle 0 of a quadrature (also comprise and) with the contacting part of this ring 25 and two friction wheels; But because above-mentioned support unit is away from the position supporting ring of contacting part; Therefore the tilt angle of ring is stable; Can easily carry out the speed of correct variable speed operation and constant speed and keep operation; And can be easily and set the tilt angle of the ring corresponding reliably with the travelling speed of moving member 63, can carry out the speed change under the rapid response speed.
Above-mentioned moving member 63 has at the linking department that between the ball nut portion 65 of upper end and the slide part 66 in the lower end, is circular-arc extension with the mode along the outside of input side friction wheel 22; Be formed with the groove 71 of Rack and prescribed depth at the inner peripheral surface of this linking department, so that take in above-mentioned ring 25.And front end is fixed with oily conductor 72 in the underpart of above-mentioned moving member 63.Oil conductor 72 is made up of the sheet metal parts, and its cross section constitutes for " コ " font and by the circular-arc of predetermined angular, takes in above-mentioned ring 25 at its recess.The front end of this oil conductor 72 is positioned near the position of ring with the contacting part of friction wheel in the scope of not interfering with outlet side friction wheel 23, forms free end, extends along the periphery of above-mentioned ring 25.In addition, the recess of above-mentioned groove 71 and oily conductor 72 is set to: even when carrying out variable speed operation, encircle the width that 25 deflections also can not interfered with this ring.And,, therefore can correspondingly reduce can improve the compactedness of conical ring formula CVT3 to the outstanding size of ring outside diameter because moving member 63 its inner peripheral surface have the groove 71 of taking in ring 25.
And then the guide rail 62 of above-mentioned variable speed operation unit 60 and slide part 66 axially are dipped in above-mentioned oil conservator 59 in (movement direction) whole show scope at it.In addition, lower support parts 69 also are dipped in above-mentioned oil conservator 59 in axial (movement direction) whole show scope of moving member 63.On the other hand, be positioned at moving member 63 top ball nut portion 65 and ballscrew shaft 61 its axially (movement direction) whole show scope be positioned at the top of pasta 59a.In addition, upper support parts 67 also are positioned at the top of pasta 59a in axial (movement direction) whole show scope of moving member 63, be not dipped in oil conservator 59.In addition; Before vehicle and then conical ring formula CVT3 when just changeing; Input side friction wheel 22 rotates towards the arrow K of Fig. 4 direction; Above-mentioned ring 25 is at it axially in (movement direction) whole show scope, from the state that is dipped in oil conservator 59 to rotate to the top towards the mode of the contacting part of this ring 25 and two friction wheels 22,23.And; In the above-described embodiment; Though guide rail 62 and slide part 66 are dipped in oil conservator 59 in its movement direction whole show scope, also can in the whole show scope, be dipped in above-mentioned oil conservator 59, the axial part that also can be configured to guide rail 62 is positioned at the top of pasta 59a.
Therefore; No matter conical ring formula CVT3 just changes or reverses; Any shift position during from high speed position to the lowest speed position; The guide rail 62 and the slide part 66 of variable speed operation unit 60 always are dipped in oil conservator 59, and the feed screw mechanism that is made up of ballscrew shaft 61 and ball nut portion 65 is positioned at the top of pasta 59a.Though when the rotation that utilizes ballscrew shaft 61 makes moving member 63 move abreast along the opposed plane of inclination of two friction wheels 22,23; The slide mechanism that is made up of guide rail 62 and slide part 66 always is positioned at oil conservator; Moving member 63 is moved along sliding parallel; But feed screw mechanism always is positioned at the top of pasta 59a, and does not stir the oil of oil conservator 59, can not produce the energy loss that causes because of this oil stirring.And then when vehicle advanced, ring 25 was also along the rotation of the arrow K direction of Fig. 4, this ring 25 oil of in oil conservator 59, kicking up, and the oil that is risen by this endless belt is directed to oily conductor 72, and is directed to the contacting part with above-mentioned two friction wheels 22,23.The traction of the abundant amount that is produced by this oil conductor 72 is installed in the contacting part of 25 and two friction wheels 22,23 of ring with oil; Carry out reliable frictional power transmission thus based on above-mentioned shearing force; And be accompanied by rotation along the moving axially of sliding ring 25, carry out quick variable speed operation thus exactly.In addition, the part of oil is supplied to upper support parts 67 with ring 25 by drive, and disperses by centrifugal force, is supplied to ballscrew shaft 61 and ball nut portion 65.And then the part oil that is attached to ring 25 is directed to the groove 71 of moving member 63, returns oil conservator 59.
Disperse and the oil that is supplied to ballscrew shaft 61 is fed into and wants the above-mentioned thread spindle 61 that screws togather with ball nut portion 65 from above-mentioned ring 25; Correspondingly accurately be supplied to the above-mentioned ball screw shaft portion that the position that is screwed togather by ballscrew shaft and nut portions constitutes and needs are lubricated according to moving of above-mentioned ring 25; Even ballscrew shaft is positioned at the top of pasta 59a, also can utilize suitable lubricating along moving member 63 is moved slidingly.And guide rail 62 is dipped in oil conservator 59 with slide part 66, thereby utilizes lubricatedly fully along guiding moving member 63 slidingly, and even above-mentioned slide part 66 is dipped in oil conservator 59, the slip work of above-mentioned slide part 66 also not too influences the stirring of oil conservator.
When conical ring formula CVT3 was just changeing, the lower support parts 69 that are dipped in oil conservator 59 became the axially movable working part of limit collar 25, and this working part can make ring 25 along rotating slidingly in oil conservator 59, and limits moving axially of this ring 25.On the other hand, because upper support parts 67 allow moving axially of ring 25, the oil that therefore is attached to ring 25 is lubricated fully, can not damage the rotation of ring 25.
On the other hand, when vehicle rollback, ring 25 is along the rotation of the opposite directions of arrow K, is dipped in the oil that the ring 25 of oil conservator 59 kicks up and is moved groove 71 guiding of parts 63 and drives and guide to upper support parts 67.When conical ring formula CVT3 reversed, upper support parts 67 became the axially movable working part of limit collar, utilized by the more sufficient oil of above-mentioned groove 71 guiding to be lubricated, and made ring 25 along rotating slidingly, and limited moving axially of this ring 25.And then, be accompanied by ring 25 rotation and the oil that further drives is supplied to the contacting part of ring and friction wheel, carry out based on the friction driving of above-mentioned shearing force and encircle 25 move axially.At this moment, compare when just changeing, when reversing; Though it is less to become the oil mass of contacting part of upper support parts 67 and ring and friction wheel of axially locating working part of ring; But compare when advancing, the service time of the fallback state of vehicle is a lot of less, and necessary torque capacity and speed change zone are also smaller; Therefore; Even above-mentioned fewer oil mass can not counteract frictional power transmission and variable speed operation yet, can be accurately and along carry out transmission of power and variable speed operation slidingly.
In addition; Though variable speed operation unit 60 carries out variable speed operation through moving vertically; So that the part of the upstream side that is positioned at rotation of carrier ring 25, but be not limited thereto, also can operate and make its inclination encircling 25; Make this ring move axially (for example, with reference to the WO2005/061928 communique) along the tilt angle.
