On step in the middle of described internal ring 4 external diameter, it is provided with multiple equally distributed star-wheel wedge groove, star-wheel wedge groove just raceway work surface to outer shroud 1, roller 3 is arranged in the space between the raceway work surface of outer shroud 1 and the star-wheel wedge groove of internal ring 4, the number of described roller 3 is equal with the number of internal ring 4 star-wheel wedge groove, and its quantity is at least 3.
Described clutch 2 main body is a thicker annulus, its endoporus is connected with the outer ring of middle (center) bearing 10, middle (center) bearing 10 one end is provided with the Elastic back-up ring 11 fixed in clutch 2 endoporus, described clutch 2 is arranged on the right side of internal ring 4 star-wheel wedge groove, the other end of clutch 2 is provided with multiple equally distributed protrusion pusher dog, its number is identical with the number of roller 3, internal ring 4 star-wheel wedge groove, described clutch 2 protrude above pusher dog be inserted into roller 3 both sides, clutch 2 and roller 3 can make in star-wheel wedge slot space freely movable.
On the right side of described left bearing 6 inner ring and internal ring 4 junction is provided with left baffle ring 7.
On the left of described middle (center) bearing 10 inner ring and internal ring 4 junction is provided with middle baffle ring 8.
On the right side of described middle (center) bearing 10 inner ring and right bearing 5 junction is provided with right baffle ring 9
As it is shown in figure 5, its entirety also can be divided into disome manufacture by described internal ring 4, being divided into internal ring 4 and inner axle 17, both connect with flat key 16.
The operation principle of the present invention is as follows:
The present invention operation principle distinguishing with conventional freewheel clutch.
It is both provided with spring in conventional freewheel clutch, active force by spring promotes roller to contact with outer shroud, one initial frictional force is provided, start clutch work, the contactless roller clutch of the present invention, eliminate spring, be provided with a clutch 2, when utilizing clutch to rotate clutch 2 produce inertia force and structural relation realize engage and separate.
Shown in Fig. 3, when main frame is opened, when driving internal ring 4 to be rotated clockwise, the clutch 2 being contained on the middle (center) bearing 10 in the middle of internal ring 4 external diameter relies on inertia, after counter clockwise direction, (this stands on automobile as people wears roller skate pressure, when automobile leaves forward, people shrinks back, during brake or when moveing backward, the inertia force phenomenon that people moves forward again), the roller 3 being contained in clutch 2 pusher dog is pressed to outer shroud 1 and the narrower place of internal ring 4 star-wheel wedge groove, roller 3 by frictional force effect by wedging between outer shroud 1 and internal ring 4 star-wheel wedge groove, thus drive outer shroud 1 to rotate together, at this moment clutch is in engagement state.
Shown in Fig. 4, when outer shroud 1 rotating speed exceedes internal ring 4 or when driving host inverts (counterclockwise), outer shroud 1 or the frictional force of internal ring 4 and the inertia force of clutch 2, shift the rear portion that internal ring 4 star-wheel wedge groove is wider onto by roller 3, and at this moment clutch is in separation (surmounting) state；In surmounting operating, clutch 2 pusher dog head and roller 3 external contact, roller 3 is pressed in star-wheel wedge groove rear portion by the inertia force of clutch 2, makes roller 3 cannot contact with outer shroud 1, it is achieved that (high, low speed) noncontact operating at full speed.
Fig. 6 is contactless post freewheel clutch application example in rotating difference speed ratio automatic transmission, and power shaft 21 and the output shaft 28 of described rotating difference ratio gearbox are set in parallel in casing 27, and two ends are supported by bearing 30.Two freewheel clutches 22,24 turning to difference (formal dress, an anti-dress) it are provided with on external diameter in the middle part of described power shaft 21；B, the C two gear pair to different speed ratios, the B gear wheel 23 of B centering is contained on left freewheel clutch 22, and the little gear of C centering C 25 is contained on right freewheel clutch 24, and the little gear of B 25 and C gear wheel 29 is contained on output shaft 28.The present invention is according to the principle of freewheel clutch unidirectional delivery torque, and two turn to different freewheel clutches 22,24 respectively to drive a pair gear pair to rotate, under the conditions of same input speed when forward and backward, it is achieved that the output of positive and negative different speed ratios.In this drive system, when the left freewheel clutch 22 of B gear wheel 23 engages, when driving the little gear of B 26 to make output shaft 28 make high-speed rotation, another C gear wheel 29 on output shaft 28 feeds back the little gear of C 25 engaged with him, make unassembled right freewheel clutch 24 outer shroud 1 rotating speed higher than the rotating speed with internal ring 4, at this moment two clutches 22,24 on power shaft 21 close simultaneously, and motion is cut off.The reason of cut-off is that the thrust that the spring in common freewheel clutch provides makes roller be rubbed by outer shroud, and caused by wedging.Loading onto contactless post freewheel clutch, in clutch, roller 3 is pressed in star-wheel wedge groove rear portion by the inertia force of clutch 2, and roller 3 cannot contact with outer shroud 1, has successfully cracked and has ended this, makes positive and negative different speed ratio variator normally work.
The foregoing is only a preferred embodiment of the present invention, it is impossible to limit the invention, all within the spirit and principles in the present invention, any made amendment, part replacement, improvement etc., should be included within the scope of the present invention.
