In order that those skilled in the art more fully understand the utility model, below in conjunction with the accompanying drawings and it is embodied The utility model is described in further detail for mode.
Fig. 1 to Fig. 7 is refer to, Fig. 1 is a kind of embodiment of freewheel clutch provided by the utility model Explosive view;Fig. 2 is that a kind of structure of embodiment China and foreign countries control panel of freewheel clutch provided by the utility model is shown It is intended to;Fig. 3 be freewheel clutch provided by the utility model a kind of embodiment in interior control panel structural representation Figure;Fig. 4 is a kind of positive mono-directional overrun working condition of embodiment of freewheel clutch provided by the utility model Schematic diagram;Fig. 5 is a kind of reverse mono-directional overrun work of embodiment of freewheel clutch provided by the utility model View;Fig. 6 is a kind of bidirectional overtaking work of embodiment of freewheel clutch provided by the utility model View;Fig. 7 is a kind of two-way engaging work of embodiment of freewheel clutch provided by the utility model View.
The freewheel clutch that the utility model embodiment provides, including main shaft 3, the and of inner ring 600 being coaxially disposed Outer ring 700, main shaft 3 are fixedly connected with inner ring 600, and multiple two-way voussoirs are provided between inner ring 600 and outer ring 700, are pacified on main shaft 3 Equipped with the 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 Forward direction is used to represent two opposite directions of motion with inversely (reverse), when it is positive to provide a 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 connected using spline, within the scope of protection of the utility model.
Switch the working position of two-way voussoir by control device, make freewheel clutch that there is positive mono-directional overrun, reverse list To surmount, four kinds of working conditions of bidirectional overtaking and two-way engagement, realize two-way controllable, meet the needs of multiple-working mode, carry High applicability.
In the freewheel clutch that the utility model embodiment provides, two-way voussoir has diversified forms, can be with For V-type voussoir 400, i.e. section is in alphabetical V-type, can also use other forms, such as U-shaped or U shape.The periphery pair of inner ring 600 Multiple mounting grooves at the base angle for installing multiple V-type voussoirs 400 should be provided with, the inner circumferential of outer ring 700 is correspondingly arranged on multiple locks Only groove, i.e., 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 rotates, 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 rotates, 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 both ends drift angle of V-type voussoir 400 and corresponding lock groove 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 both ends drift angle of block 400 separates 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.
