Detailed description of the invention
Shown in below in conjunction with the accompanying drawings, optimum implementation of the present invention is described in further detail.
As it is shown in figure 1, the embodiment of the present invention provide a kind of rotating difference speed ratio automatic transmission, including power shaft 1,
Directional overrunning clutch (2,4), gear (3,6,7,12), screw (5,14), casing 8, output shaft 9, circlip 10, flat key 11,
Bearing 13, end cap 15, described power shaft 1 and output shaft 9 be set in parallel in casing 8, and power shaft 1 and output shaft 9 two ends are passed through
Bearing 13 is connected with casing 8.
It is provided with on described power shaft 1 and turns to different left directional overrunning clutchs 2 and right directional overrunning clutch 4；Described
A, the B two gear pair to different speed ratios, the B gear wheel 3 of gear pair is arranged on left directional overrunning clutch 2 outer shroud by B, and A is to tooth
The little gear of A 6 in wheel set is arranged on right directional overrunning clutch 4 outer shroud；On described output shaft 9, the left side is provided with the little gear of B 7,
The right is provided with A gear wheel 12, and the little gear of described B 7 is meshed with B gear wheel 3 on power shaft 1, A gear wheel 12 and power shaft 1
The little gear of upper A 6 is meshed.
Described left directional overrunning clutch 2 and right directional overrunning clutch 4 are all connected with power shaft 1 by flat key 11, and on a left side
Flexible back-up ring 10 is all blocked in directional overrunning clutch 2 and right directional overrunning clutch 4 both sides.
Described B gear wheel 3 is connected with left directional overrunning clutch 2 outer shroud by flat key 11 and is all blocked in B gear wheel both sides to be had
Circlip 10.
The little gear of described A 6 is connected with the right outer plane of a loop of directional overrunning clutch 4 by the first screw 5.
The little gear of described B 7 and A gear wheel 12 is all connected with output shaft 9 by flat key 11 and flexible back-up ring is all blocked in both sides
10。
Described bearing 13 is outer is all provided with end cap 15, and described end cap 15 connects casing 8 with the second screw 14.
Described left directional overrunning clutch 2 and right directional overrunning clutch 4 all should be the contactless roller of (high, low speed) at full speed
Freewheel clutch or non-contact wedge block overrunning clutch.
The automatic transmission of described rotating difference speed ratio, two A, B gears to being meshed, the centre-to-centre spacing of every pair is identical
, under conditions of meeting identical centre-to-centre spacing, convert every pair of number of gear teeth, just can meet various rotating difference speed ratio and want
Ask.
Described power shaft and output shaft can phase inversion, conversion output, the position of input mutually, overdrive clutch need not be converted
The direction of device, can convert the direction of the rotating of the different rotating speeds of output.
The operation principle of the present invention is: the automatic transmission of rotating difference speed ratio, is according to the unidirectional biography of freewheel clutch
Pass the principle of torque, be arranged on power shaft two are turned to the freewheel clutch of difference (formal dress, an anti-dress), point
Not from two, A, B gear pair of different speed ratios is not connected.When power shaft rotates forward, the freewheel clutch of forward drives a pair A gear
Auxiliary driving, during power shaft reversion, reverse freewheel clutch drives another B gear pair transmission to different speed ratios, same in input
Under conditions of one speed, reach the output of forward and backward friction speed automatically.
When power shaft 1 rotates forward, the right clutch 4 of forward engages, and the little gear of A 6 drives A gear wheel 12 turns on output shaft
Dynamic, output shaft 9 exports the slowest speed.At this moment, the another clutch 2 on power shaft 1 is in released state, and from defeated
The little gear of another B 7 on shaft 9 feeds back the B gear wheel 3 on band driven input shaft 1, and at this moment the rotating speed of clutch 2 outer shroud is less than
Internal ring, transmission duty is normal.
When power shaft 1 inverts, reverse left clutch 2 engages, and B gear wheel 3 drives the little gear of B on output shaft 7 to rotate,
Output shaft 9 exports the speed that forward is fast.But it is little that the another A gear wheel 12 on output shaft 9 feeds back the A on band driven input shaft 1
Gear 6, makes internal ring 24 rotating speed that outer shroud 21 rotating speed of unassembled right clutch 4 is higher than equidirectional turn, and right clutch 4 is also connect
Closing, the clutch 2,4 of positive and negative two different rotating speeds on power shaft 1 simultaneously engages with, and variator rotates and is just cut off.
The reason of cut-off is that the thrust that common directional overrunning clutch inner spring provides makes roller be rubbed and wedging by outer shroud, makes
Right clutch is become to engage.There is no spring inside contactless roller overrunning clutch, be provided with a clutch, be to utilize clutch
When device rotates, roller is pressed in the star-wheel wedge groove rear portion of internal ring by the inertia force that clutch produces, and roller cannot contact with outer shroud, keep away
Exempt from right clutch to be also engaged, successfully cracked and ended this, made variator normally work.
As in figure 2 it is shown, the contactless roller overrunning clutch of described one, mainly include outer shroud 21, clutch 22, rolling
Post 23, internal ring 24, bearing 25, middle (center) bearing 26, internal ring 24 is nested with in outer shroud 21, and outer shroud 21 two ends endoporus is connected to internal ring two ends
On the outer ring of two spring bearings 25, internal ring 24 external diameter intermediate step arranges multiple star-wheel wedge groove, and the outside of star-wheel wedge groove is right
Raceway in outer shroud 21 endoporus, roller 23 is contained in outer shroud 21 raceway and internal ring 24 star-wheel wedge slot space.Described clutch 22 is main
Body is a thicker annulus, and its endoporus is contained on the outer ring of middle (center) bearing 26, the other end plane of clutch 22 is provided with many
The pusher dog of individual protrusion, the pusher dog of protrusion is inserted into roller 23 both sides.Contactless roller overrunning clutch, is to utilize clutch to turn
Time dynamic, deadweight inertia that clutch 22 produces and pusher dog structural relation realize engaging and separate, in surmounting rotation, deciliter
Roller is pressed in the bottom that internal ring 24 star-wheel wedge groove is wider by device 22 pusher dog, makes roller 23 cannot contact with outer shroud 21, it is achieved that complete
Speed (high, low speed) noncontact, it is to avoid the abrasion caused because of sliding friction, thus it is long to make clutch have the life-span, work turns
The feature that speed is high.
The foregoing is only a more excellent embodiment of the present invention, all within the spirit and principles in the present invention, appoint
The amendment of He Suozuo, part replacement, improvement etc., should be included within the scope of the present invention.
