It is shown below in conjunction with the accompanying drawings that optimum implementation of the present invention is described in further detail.
As shown in figure 1, a kind of automatic transmission of the not synchronized ratio of rotating of offer of the embodiment of the present invention, including input 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, the input shaft 1 and output shaft 9 are set in parallel in casing 8, and input shaft 1 and the two ends of output shaft 9 pass through
Bearing 13 is connected with casing 8.
It is provided with the input shaft 1 and turns to different left directional overrunning clutch 2 and right directional overrunning clutch 4；It is described
The gear pair of the not synchronized ratios of two couples of A, B, B is arranged on the left outer shroud of directional overrunning clutch 2 to the B gear wheels 3 of gear pair, and A is to tooth
A little gears 6 in wheel set are arranged on the right outer shroud of directional overrunning clutch 4；The left side is provided with B little gears 7 on the output shaft 9,
The right is provided with A gear wheels 12, and the B little gears 7 are meshed with B gear wheels 3 on input shaft 1, A gear wheels 12 and input shaft 1
Upper A little gears 6 are meshed.
The left directional overrunning clutch 2 and right directional overrunning clutch 4 are connected by flat key 11 with input shaft 1, and on a left side
Flexible back-up ring 10 is all blocked in directional overrunning clutch 2 and the both sides of right directional overrunning clutch 4.
The B gear wheels 3, which are connected and all blocked in B gear wheels both sides with the left outer shroud of directional overrunning clutch 2 by flat key 11, to be had
Circlip 10.
The A little gears 6 are connected by the first screw 5 with the outer plane of a loop of right directional overrunning clutch 4.
The B little gears 7 and A gear wheels 12 are connected by flat key 11 with output shaft 9 and flexible back-up ring is all blocked in both sides
10。
The bearing 13 is outer to be all provided with end cap 15, and the end cap 15 connects casing 8 with the second screw 14.
The 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 the not synchronized ratio of the rotating, two pairs of A, B gears for being meshed, the centre-to-centre spacing of each pair is identical
, under conditions of identical centre-to-centre spacing is met, each pair number of gear teeth is converted, with regard to various rotatings can be met not at the same speed than wanting
Ask.
The input shaft and output shaft can mutual phase inversions, conversion output, the position of input, without converting overdrive clutch
The direction of device, can convert the direction of the rotating of the different rotating speeds of output.
The present invention operation principle be：The automatic transmission of the not synchronized ratio of rotating, is unidirectionally passed according to freewheel clutch
The principle of torque is passed, the freewheel clutch for turning to different (formal dress, an anti-dresses) by two be arranged on input shaft, point
A, B gear pair not with two pairs of not synchronized ratios is connected.When input shaft is rotated forward, positive freewheel clutch drives a pair of A gears
Auxiliary driving, when input shaft is inverted, reverse freewheel clutch drives the B gear auxiliary driving of the not synchronized ratio of another pair, same in input
Under conditions of one speed, the output of forward and backward friction speed is automatically reached.
When input shaft 1 is rotated forward, positive right clutch 4 is engaged, and A little gears 6 drive 12 turns of A gear wheels on output shaft
Dynamic, output shaft 9 exports reversely slow speed.At this moment, the another clutch 2 on input shaft 1 is in released state, and from defeated
Another B little gears 7 on shaft 9 are fed back with the B gear wheels 3 on driven input shaft 1, and at this moment the rotating speed of the outer shroud of clutch 2 is less than
Inner ring, transmission duty is normal.
When input shaft 1 is inverted, reverse left clutch 2 is engaged, and B gear wheels 3 drive B little gears 7 on output shaft to rotate,
Output shaft 9 exports positive fast speed.But the another A gear wheels 12 on output shaft 9 feed back small with the A on driven input shaft 1
Gear 6, makes inner ring 24 rotating speed of the rotating speed of outer shroud 21 higher than equidirectional turn of unassembled right clutch 4, and right clutch 4 is also connect
Close, the clutch 2,4 of positive and negative two different rotating speeds on input shaft 1 is simultaneously engaged with, speed changer is rotated and is just cut off.
The reason for cut-off is that the thrust that common directional overrunning clutch inner spring is provided makes roller wedging by outer shroud friction, is made
Engaged into right clutch.It is to utilize clutch provided with a clutch without spring inside contactless roller overrunning clutch
When device is rotated, roller is pressed in the star-wheel wedge groove rear portion of inner ring by the inertia force that clutch is produced, and roller can not be contacted with outer shroud, kept away
Right clutch is exempted from also to be engaged, has successfully cracked and ended this, made speed changer normal work.
As shown in Fig. 2 a kind of described contactless roller overrunning clutch, mainly includes outer shroud 21, clutch 22, rolling
Post 23, inner ring 24, bearing 25, middle (center) bearing 26, inner ring 24 are nested with outer shroud 21, and the two ends endoporus of outer shroud 21 is connected to inner ring two ends
On the outer ring of two spring bearings 25, the external diameter intermediate step of inner ring 24 sets multiple star-wheel wedge grooves, and the outside of star-wheel wedge groove is right
Raceway in the endoporus of outer shroud 21, roller 23 is mounted in the raceway of outer shroud 21 and the star-wheel wedge slot space of inner ring 24.The clutch 22 is led
Body is a thicker annulus, and its endoporus is provided with many on the outer ring of middle (center) bearing 26 on another transverse plane of clutch 22
The pusher dog of individual protrusion, the pusher dog of protrusion is inserted into the both sides of roller 23.Contactless roller overrunning clutch, is turned using clutch
When dynamic, deadweight inertia that clutch 22 is produced and pusher dog structural relation are realized engagement and separated, in rotation is surmounted, division
Roller is pressed in the wider bottom of the star-wheel wedge groove of inner ring 24 by the pusher dog of device 22, roller 23 can not be contacted with outer shroud 21, is realized complete
Speed（High, low speed）Noncontact, it is to avoid worn and torn because of caused by sliding friction, thus make clutch that there is long lifespan, work turns
The characteristics of speed is high.
More excellent one embodiment of the present invention is the foregoing is only, within the spirit and principles of the invention, is appointed
Modification, part replacement, improvement that what is made etc., should be included in the scope of the protection.
