The present invention relates to a kind of free wheel device, relate in particular to a kind of tri-state overrun clutch, it can be controlled the inner ring of free wheel device and outer ring and throw off fully each other and can freely rotate at positive and negative both direction.
Background technique
Free wheel device is called overrunning clutch or unilateral bearing again, be a kind of can only be at the device of a sense of rotation transmitting torque.Existing overrun mainly comprises roller-type overrunning clutch and Wedge type over running clutch.
An example as Wedge type over running clutch, CN 2476675Y (perhaps CN 1430000A) discloses a kind of free wheel device with two retainers, this free wheel device comprises inner ring and outer ring, between inside and outside circle, be provided with a plurality of voussoirs, and these voussoirs are kept by the retaining hole of offering in the two retainers between the inside and outside circle (retainer and outer retainer in comprising).In this free wheel device,, can improve the bearing capacity of free wheel device and prolong its working life by using two retainer structures.
But, in existing overrun, all be to surmount state and jointing state by what relatively rotating between the inside and outside circle realized free wheel device, clutch itself does not have additional mechanism that the working position of voussoir is controlled, therefore the problem that exists is, free wheel device only has mono-directional overrun state and one-way engagement state, function singleness.In some concrete engineering machinery applications, need free wheel device under the situation of high speed rotating, driving link separates fully with driven member, and promptly initiatively, driven member can mutual noninterference, and the mono-directional overrun of free wheel device has limited this function.Simultaneously, clutch is surmounting under the state at a high speed, and voussoir contacts with inside and outside circle, thus there is the problem of wearing and tearing, heating to exist, thus influence its working life.
Summary of the invention
The purpose of this invention is to provide a kind of tri-state overrun clutch, it not only has the function of common mono-directional overrun clutch, and can realize that outer ring and inner ring are in positive and negative two-way working state of all throwing off (being that inside and outside circle is positive and negative two-way can both freely the rotation) fully, promptly two-way separated state.
To achieve these goals, the invention provides a kind of tri-state overrun clutch, this tri-state overrun clutch comprises the outer ring, inner ring, a plurality of voussoirs between outer ring and inner ring are between outer ring and inner ring and keep the outer retainer and the interior retainer of described a plurality of voussoirs.Have a plurality of arc grooves on the working surface of described outer ring, each arc groove matches with a working surface of a corresponding voussoir, and a described working surface is remained in this arc groove.Retainer has axially outwardly directed a plurality of lugs in described, has the inclined hole with respect to axioversion on each lug.Have on the excircle of described outer ring and axially slidably stir dish, this is stirred and is fixed with a plurality of turning levers that are inserted into separately in the corresponding inclined hole on the dish.This is stirred dish and endwisely slips on the excircle of described outer ring by the electromagnetic drive mechanism driving.
In this tri-state overrun clutch, can obtain two working positions of this clutch, three kinds of working staties, promptly common wedging working position (this position has mono-directional overrun and two kinds of working staties of unidirectional wedging) and the two-way mask work position of surmounting.
Particularly, stir dish by electromagnetic drive mechanism control and endwisely slip on the outer ring, the turning lever of stirring dish slides in inclined hole.Because retainer rotated corresponding angle with respect to the outer ring in inclined hole with respect to the axis tilt several angle, therefore can drive.Simultaneously, because a working surface of voussoir is maintained in the arc groove on the working surface of outer ring, so will between inside and outside circle, rotate corresponding angle around described arc groove by the voussoir that inside and outside retainer kept, can control voussoir thus and leave the inner ring working surface fully, make outer ring and inner ring two-wayly freely to rotate, obtain the two-way mask work state of this clutch positive and negative.Otherwise, turn back to home position (for example passing through Returnning spring) if stir dish, then can control voussoir and return to and commonly surmount the wedging working position, thereby obtain the mono-directional overrun or the unidirectional wedging working state of this clutch.
Because this clutch is the extra working state (two-way separated state) that increases on the basis of traditional mono-directional overrun clutch, therefore this free wheel device can be called as tri-state overrun clutch.When using this tri-state overrun clutch, can use separated state to replace surmounting state in some cases, thus the wearing and tearing under can avoiding at a high speed, the working life of improving clutch; Conversion is smooth-going between two working positions under fast state, and noise is little, and reliability improves; Can also be for double dynamical input provide adequate condition, inside and outside circle can connect two power sources, and two power sources can be exported respectively or synthetic output; Clutch is operated in two-way separated state can avoid the anti-driving link that drags of driven member.
