Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples, but should not be construed the above-mentioned theme of the present invention
Range is only limitted to following embodiments.Without departing from the idea case in the present invention described above, known according to ordinary skill
Knowledge and customary means, make various replacements and change, should all include within the scope of the present invention.
A kind of mechanical flexible shifting device, including two kinds of structure types: series and parallel type.
(1) cascaded structure form
Mechanical flexible shifting device of connecting includes: duplicate gear 1, clutch housing 2, friction plate 3, flute profile gasket 4, bullet
Spring 5, spline fitting 6 push away column base 7, nut 8, direct current generator 9 of shifting gears, splined shaft 10, duplicate gear 11, integral type screw gear 12.
The duplicate gear 1 and 11 side of duplicate gear are engaged with gear, and the other side is engaged with friction plate 3, and are equipped with interior
Involute spline.2 inside connected in star with teeth of clutch housing, central projection position outer wall are equipped with rectangular spline, and equipped in gradually
Burst at the seams spline.
6 outer wall of spline fitting is equipped with outer involute spline, after being pushed away that column base 7 is axial and being pushed with duplicate gear 1 or double
Join 11 spline engagement of gear.6 inner wall of spline fitting is equipped with rectangular spline, engages always with 2 rectangular spline of clutch housing.
The column base 7 that pushes away is hollow annulated column, and standing on ring has 6 circles to push away column；12 gear part of integral type screw gear
Divide and engaged with shift 9 output shaft gear of direct current generator, screw portion is in conjunction with 8 spiral of nut, and thread rotary orientation is identical at two.
Further, when direct current generator 9 of shifting gears is with the rotation of a certain rotation direction, integral type spiral shell is driven with gear engaged transmission relation
Bar gear 12 rotate, at this time nut 8 due to integral type screw gear 12 rotation, by worm drive relationship, along splined shaft
10 axial generation translational motion.
Further, on the one hand the translational motion of nut 8 pushes 12 side of integral type screw gear to push away column base 7 towards clutch
The movement of device shell, so that spring 5 compresses, and then pressing friction piece 3 and flute profile gasket 4, the duplicate gear of the side, which is begun through, to rub
Pad 3 transmits low torque to clutch housing 2, and clutch housing 2 transfers torque to splined shaft 10 by involute spline and exports
Low torque.When nut 8 continues translation, involute flower in the outer involute spline and the side duplicate gear of spline fitting 6 will push
Key enters meshing relation.For duplicate gear by spline rigid of transmission large torque to spline fitting 6, spline fitting 6 passes through rectangular flower at this time
Key transfers torque to clutch housing 2, then transfers torque to splined shaft 10 by clutch housing and export large torque；On the other hand one
The column base 7 that pushes away of 12 other side of body formula screw gear moves under the action of 5 restoring force of spring far from shell, so that the spline of the side
Outer involute spline is in involute spline in the side duplicate gear and is disengaged from state, and friction plate 3 and flute profile on seat 6
Gasket 4 is in malcompression state, which cannot transfer torque to splined shaft 10.
Further, when direct current generator 9 of shifting gears is with opposite rotation direction rotation, so that the spiral shell of 12 two sides of integral type screw gear
It is female, push away column base, spline fitting, spring, clutch housing, friction plate, flute profile gasket and duplicate gear etc., exchange relative motion, nibble
It closes or movements or the contact relations such as compression, realization is shifted gears, and gear has interlocked relationship.
(2) parallel-connection structure form
Parallel connection machinery type flexible shifting device includes: duplicate gear 1, clutch housing 2, friction plate 3, flute profile gasket 4, bullet
Spring 5, spline fitting 6 push away column base 7, nut 8, direct current generator 9 of shifting gears, splined shaft 10, duplicate gear 11, integral type screw gear 13,
Integral type screw gear 14.
The duplicate gear 1 and 11 side of duplicate gear are engaged with gear, and the other side is engaged with friction plate 3, and are equipped with interior
Involute spline.2 inside connected in star with teeth of clutch housing, central projection position outer wall are equipped with rectangular spline, and equipped in gradually
Burst at the seams spline.
6 outer wall of spline fitting is equipped with outer involute spline, after being pushed away that column base 7 is axial and being pushed with duplicate gear 1 or double
Join 11 spline engagement of gear.6 inner wall of spline fitting is equipped with rectangular spline, engages always with clutch housing 2.
The column base 7 that pushes away is hollow annulated column, and standing on ring has 6 circles to push away column；The integral type screw gear 13, integral type
14 gear parts of screw gear are engaged with shift 9 output shaft gear of direct current generator, and screw portion is in conjunction with 8 spiral of nut.
Further, when direct current generator 9 of shifting gears is rotated along a certain rotation direction, integral type spiral shell is driven by gear drive relationship
Bar gear 13, integral type screw gear 14 rotate, and two integral type screw gear direction of rotation are identical.Due to two integral types
Thread rotary orientation on screw gear on the contrary, make 8 one, two nuts close to clutch housings 2 another far from clutch housing 2.
Further, the direction of motion pushes away column base 7 and moves to clutch housing 2, push away close to the nut of clutch housing 2
Column base 7 pushes 6 holddown spring 5 of spline fitting, 5 pressing friction piece 3 of spring and flute profile gasket 4.At this point, the side duplicate gear is by rubbing
Pad 3 transfers torque to clutch housing 2, and clutch housing 2 transfers torque to the side splined shaft 10 by involute spline, defeated
Low torque out.When the nut continues to push the outer involute spline and duplicate gear of spline fitting 6 close to the movement of clutch housing 2
Internal spline engagement.At this point, duplicate gear passes through spline transmitting large torque to spline fitting 6, spline fitting 6 passes through square key and transmits torsion
Square transfers torque to side splined shaft output by involute spline to clutch housing 2, then by clutch housing 2.Another party
Face, nut of the direction of motion far from clutch housing 2, so that the lateral spring 5 pushes spline fitting 6 to transport far from shell due to restoring force
Dynamic, the outer involute spline of spline fitting and the interior involute spline of duplicate gear are in the state being disengaged from, and friction plate 3
No longer compressed with flute profile gasket 4, the side duplicate gear can not input torque to splined shaft.
Further, when direct current generator 9 of shifting gears reversely rotates, the moving component exchange movement position at left and right sides of motor is closed
System, so that the splined shaft of the splined shaft of script output torque no longer output torque and the other side can realize shift with output torque
And gear interlocking.
A kind of mechanical flexible shifting device provided by the invention, its working principle is that:
Direct current generator shift gears by gear drive driving integral type screw gear rotation, integral type screw gear drives two
Nut translational motion.In parallel structure, two nuts are due to thread rotary orientation mutually counter motion instead；In series-mode frame
In, two nuts move in the same direction since thread rotary orientation is identical.Since the movement position relationship of two nuts and shell is on the contrary, side
Friction plate be compacted with flute profile gasket and the other side is loosened.Nut further movement, so that the outer involute of the spline fitting of two sides
Interior involute spline one of spline and duplicate gear engages another disengaging.Friction plate and flute profile gasket, interior external splines is not
Same movement relation, enables a duplicate gear input torque and another is unable to input torque, with this realize shift and
The function of gear interlocking.In parallel structure, torque is exported by different splined shafts when shift, and in series-mode frame,
Torque is exported by the same splined shaft when shift.
