Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be apparent to effect, be expanded on further how this utility model patent is implemented in conjunction with accompanying drawing:
A kind of central authorities two-way automatic differential lock of in good time four-wheel drive cars, see Fig. 1-1 and Fig. 1-2, formed by with lower component, driving shaft 1, drag ring 2, commutative ring 3, retainer ring 4, shell 5, drivewheel 6, driven pulley 7, commutation block assembly 8, self-locking roller 9, commutation roller 10, alignment pin 11, jump ring 12；Drivewheel 6 outer rim, with more than one Baltimore groove, is installed on driving shaft 1 with pin；Commutation block assembly 8 is installed on drivewheel 6；Self-locking roller 9 is installed in commutation block assembly 8；Commutation roller 10 commutative ring 4 is limited between commutation block 8 and retainer ring 4；Commutative ring 3 driven by alignment pin 11 in its locating slot and cause commutate roller 10 move drive commutation block 8 swing and realize commutation；Retainer ring 4 is between commutation roller 10 and shell 5；Drag ring 2 is between shell 5 and commutative ring 3；Driven pulley 7 is connected with output shaft；Connect with jump ring 12 between commutation block 8 two-by-two.
In the present embodiment, driving shaft 1 is connected with transfer case output shaft or active bridge power transmission shaft, and driven pulley is connected with in good time drive axle power transmission shaft.(the speed discrepancy interval of drivewheel and driven pulley can be regulated by changing the gear ratio of antero posterior axis)
By Fig. 2-1 to Fig. 2-2, drivewheel 6 outer rim being arranged on driving shaft with pin, with more than one Baltimore groove, sets commutation hole in the middle part of the radial direction that Baltimore groove is corresponding, and the mandrel of commutation block assembly 8 is installed therein, free to rotate.One end of commutation block assembly mandrel 81 is equipped with the commutation block 83 of band draw-in groove, and the other end is arranged between two draw-in grooves equipped with the commutation work block 82 of band draw-in groove and work surface, self-locking roller 9.
By Fig. 3-1, commutative ring 3, can be the most freely rotatable relative to drivewheel 6 under its side locating slot and alignment pin 11 control.Two commutation rollers 10 are installed in each draw-in groove of commutative ring 3.Two commutation rollers 10 are installed and can reduce the anglec of rotation of drivewheel in commutation process, improve the sensitivity during commutation of this mechanism.When drivewheel 6 rotates counterclockwise, the right commutation roller 10 is pressed under on the right side of commutation block 8 work surface.When drivewheel 6 turns clockwise, left side commutation roller 10 is pressed under on the left of commutation block 8 work surface.
When transfer case output shaft drives driving shaft to rotate counterclockwise, drivewheel 6 rotates counterclockwise the most therewith, commutative ring 3 and by its draw-in groove spacing commutation roller 10 lag behind drivewheel 6 because of the effect by drag ring 2, now commutation roller 10 is pushed to by the less space formed on the left of the commutation work block work surface of retainer ring 4 and commutation block assembly, and commutation block assembly 8 deflects in drivewheel commutation hole clockwise.When the delayed alignment pin to locating slot of commutative ring 3 and commutation roller 10 is blocked and works, just rotate together with drivewheel 6.Commutation work block continues deflection certain angle under jump ring 12 acts on, and commutation work block work surface separates such as Fig. 4-1 to 4-3 with commutation roller 10.Self-locking roller 9 is also allocated to right side such as Fig. 5-1 to Fig. 5-2 of drivewheel 6 Baltimore groove by the deflection of commutation block assembly simultaneously by its draw-in groove.
In this case, if the rotating speed of drivewheel 6 is higher than the rotating speed of driven pulley 7, self-locking roller 9 is pushed to be produced self-locking by the less space formed on the right side of driven pulley 7 and drivewheel 6 Baltimore groove, and drivewheel 6 drives driven pulley 7 together to rotate.
Drivewheel rotating speed is higher than secondary speed, and namely often the operating mode skidded occurs in drive shaft, and this operating mode namely needs to increase the operating mode driven, it is achieved that the purpose being automatically brought into operation.
When the rotating speed of drivewheel 6 is less than the rotating speed of driven pulley 7, self-locking roller 9 is brought away from by the less space formed on the right side of driven pulley 7 and drivewheel 6 Baltimore groove, and the self-locking of self-locking roller 9 was lost efficacy, and driven pulley 7 can freely rotate counterclockwise, and vehicle is in single shaft driving condition.
When transfer case output shaft drives driving shaft to rotate clockwise, drivewheel 6 rotates clockwise the most therewith, commutative ring 3 and by its draw-in groove spacing commutation roller 10 lag behind drivewheel 6 because of the effect by drag ring 2, now commutation roller 10 is pushed to by the less space formed on the right side of the commutation work block work surface of retainer ring 4 and commutation block assembly, and commutation block assembly 8 deflects in drivewheel commutation hole counterclockwise.When the delayed alignment pin to locating slot of commutative ring 3 and commutation roller 10 is blocked and works, just rotate together with drivewheel 6.Commutation work block continues deflection certain angle under jump ring 12 acts on, and commutation work block work surface separates such as Fig. 4-3 with commutation roller 10.Self-locking roller 9 is also allocated to left side such as Fig. 5-2 of drivewheel 6 Baltimore groove by the deflection of commutation block assembly simultaneously by its draw-in groove.
In this case, if the rotating speed of drivewheel 6 is higher than the rotating speed of driven pulley 7, self-locking roller 9 is pushed to be produced self-locking by the less space formed on the left of driven pulley 7 and drivewheel 6 Baltimore groove, and drivewheel 6 drives driven pulley 7 together to rotate.
Drivewheel rotating speed is higher than secondary speed, and namely often the operating mode skidded occurs in drive shaft, and this operating mode namely needs to increase the operating mode driven, it is achieved that the purpose being automatically brought into operation.
When the rotating speed of drivewheel 6 is less than the rotating speed of driven pulley 7, self-locking roller 9 is brought away from by the less space formed on the left of driven pulley 7 and drivewheel 6 Baltimore groove, and the self-locking of self-locking roller 9 was lost efficacy, and driven pulley 7 can freely rotate clockwise, and vehicle is in single shaft driving condition.
