A kind of two-way engaging work view of embodiment of the freewheel clutch of offer.
The freewheel clutch that the specific embodiment of the invention is provided, including main shaft 3, inner ring 600 and the outer ring being coaxially disposed
700, main shaft 3 is fixedly connected with inner ring 600, is provided with multiple two-way voussoirs, main shaft 3 and is provided between inner ring 600 and outer ring 700
Control device for switching two-way voussoir working position；Two-way voussoir has three working positions, and control device can control two-way
Voussoir switches between three working positions.
When all two-way voussoir is in the first working position, two-way voussoir makes inner ring 600 be merely able to forward direction relative to outer ring 700
Rotate, now freewheel clutch is in positive mono-directional overrun state；When all two-way voussoir is in the second working position, two-way voussoir
Inner ring 600 is set to be merely able to rotate backward relative to outer ring 700, now freewheel clutch is in reverse mono-directional overrun state；All
When two-way voussoir is in three working positions, two-way voussoir enables inner ring 600 and outer ring 700 is two-way relatively rotates, and now surmounts
Clutch is in bidirectional overtaking state；The two-way voussoir in part is in the first working position, and the two-way voussoir of another part is in the second work
When making position, two-way voussoir makes inner ring 600 and the geo-stationary of outer ring 700, and now freewheel clutch is in two-way engagement status.Wherein
It is positive to be used to represent two opposite directions of motion with inversely (reverse), when providing a direction for forward direction, another direction
As reverse (reverse).
Specifically, limited step is provided with main shaft 3, and main shaft 3 is connected with inner ring 600 by singly-bound, can also use it
His connected mode, such as using spline connection, within protection scope of the present invention.
Switch the working position of two-way voussoir by control device, make freewheel clutch that there is positive mono-directional overrun, reverse list
To surmounting, four kinds of working conditions of bidirectional overtaking and two-way engagement, realize two-way controllable, the need for meeting multiple-working mode, carry
High applicability.
In the freewheel clutch that the specific embodiment of the invention is provided, two-way voussoir has diversified forms, can be V-type
Voussoir 400, i.e. section are in alphabetical V-type, can also use other forms, such as U-shaped or U shape.The periphery of inner ring 600 correspondence is set
Multiple mounting grooves at the base angle for installing multiple V-type voussoirs 400 are equipped with, the inner circumferential of outer ring 700 is correspondingly arranged on multiple lock grooves,
Often there is a V-type voussoir 400, that is, be correspondingly arranged on a mounting groove and a lock groove.
When V-type voussoir 400 is in the first working position, control device tilts V-type voussoir 400, it there was only one end drift angle
Offseted with the side of corresponding lock groove, this V-type voussoir 400 can make inner ring 600 can not be relative to outer ring 700 to offseting
Side is rotated, and is merely able to rotate to opposite side, when whole V-type voussoirs 400 same one end drift angle and corresponding lock groove it is same
When side offsets, freewheel clutch is in positive mono-directional overrun state.
When V-type voussoir 400 is in the second working position, control device tilts V-type voussoir 400, it there was only other end top
Angle offsets with the opposite side of corresponding lock groove, and this V-type voussoir 400 can make inner ring 600 can not be relative to outer ring 700 to phase
The side supported is rotated, and is merely able to rotate to opposite side, when other end drift angle and the corresponding lock groove of whole V-type voussoirs 400
When opposite side offsets, freewheel clutch is in reverse mono-directional overrun state.
When V-type voussoir 400 is in three working positions, control device makes the two ends drift angle and corresponding lock groove of V-type voussoir 400
Both sides separate, this V-type voussoir 400 can enable inner ring 600 relative to the Double-directional rotary of outer ring 700, when whole V-type wedges
When the two ends drift angle of block 400 is separated with the both sides of corresponding lock groove, freewheel clutch is in bidirectional overtaking state.
Therefore, when part V-type voussoir 400 is in the first working position, another part V-type voussoir 400 is in the second work
During position, control device makes multiple V-type voussoirs 400 be tilted respectively to both direction, and inner ring 600 is relative to the both direction of outer ring 700
Not rotatable, freewheel clutch is in two-way engagement status.

700 engagements, realize positive mono-directional overrun.
During reverse mono-directional overrun state, the first spherical control pin 203 of spherical control pin 103 and second is in the position of the inner
Put, the first control sheet 101 and the second control sheet 201 are located at the first V-type voussoir 401 and the left position of the second V-type voussoir 402.Compressing
In the presence of spring 500, the first V-type voussoir 401 and the second V-type voussoir 402 are that right-hand member tilts certain angle, with outer ring 700
Engagement, realizes reverse mono-directional overrun.
During bidirectional overtaking state, the first spherical interjacent position of spherical control pin 203 of control pin 103 and second,
First control sheet 101 and the second control sheet 201 are located at the first V-type voussoir 401 and the middle position of the second V-type voussoir 402.First V-type wedge
The V-type voussoir 402 of block 401 and second is fixed in the mounting groove of inner ring 600, and left and right ends are separated with outer ring 700, is realized two-way super
More.
During two-way engagement status, the second ball-type control pin 203 is in the position of the inner, and the second control sheet 201 is located at the first V
The left position of type gear block 401, in the presence of holddown spring 500, right-hand member tilts certain angle, is engaged with outer ring 700.First ball-type
Control pin 103 is in the position of outer end, and the first control sheet 101 is located at the right position of the second V-type gear block 402, in holddown spring 500
Under effect, left end tilts certain angle, is engaged with outer ring 700, so as to realize two-way engagement.
Above-mentioned left and right is merely to difference both direction, is according to circumstances defined positive and reverse at this under different situations
Within the protection domain of invention.
Specifically, six V-type voussoirs 400 can be uniformly arranged, the first control panel 100 includes three the first control sheets 101,
Second control panel 200 includes three the second control sheets 201, and the first control sheet 101 and the second control sheet 201 are alternately installed on six
In the groove of V-type voussoir 400.Also the quantity and set-up mode of each part, the protection model in the present invention can according to circumstances be adjusted
