1. when the gear of clutch is 2
See also Fig. 2, Fig. 3, Fig. 5 and Fig. 6.When internal spline clutch pawl 2 did not combine with slip copper sheathing clutch dog chain wheel 3, key connected driving gear I 4 and obtains being with spline input shaft 1 and internal spline clutch pawl I 2 to rotate behind the power; When internal spline clutch pawl 2 combined with slip copper sheathing clutch dog chain wheel 3, slip copper sheathing clutch dog chain wheel 3 was followed axle and is rotated, and realizes transmission of power.Concrete implementation procedure is following: an end of swing link 25 is connected with the U-shaped engaging lug 20 of clutch operating lever 19, and the other end is connected with the ears engaging lug of clutch line; With clutch operating lever from " leaving " pull down " closing " position (Fig. 6); The end that swing link 25 is connected with the engaging lug 20 of clutch operating lever will turn over an angle with the revolving sleeve of clutch operating lever; Clutch core line 32 is moving toward " closing " displacement of control panel 17 with tension spring 15; When the engaging lug 20 of clutch operating lever forward to swing link 25 and clutch line screw rod 33 between angle during greater than 180 °, under the effect of non-return locking framework (not shown), clutch operating lever is lockable not can resilience; All parts that connect on it make the entire mechanism self-locking along with the U-shaped engaging lug 20 of clutch operating lever turns over an angle.If the pawl of internal spline clutch pawl 2 is embedded in the pawl groove of slip copper sheathing clutch dog chain wheel 3, then connect power, power obtains transmitting; If the pawl of internal spline clutch pawl 2 is not embedded into the pawl groove interior (being that pawl and pawl head on) of slip copper sheathing clutch dog chain wheel 3; This moment, tension spring 15 was stretched; Internal spline clutch pawl 2 turns round immediately after connecting power, and slip copper sheathing clutch dog chain wheel 3 receives the constraint of parts such as chain, output sprocket, can not rotate; And tension spring 15 can be given 23 1 power of fork portion of shift fork all the time through the revoliving arm 24 of shift fork; Shift fork piece 22 is in the hole of fork portion 23 distal end, to rotate, and no matter what angle shift fork 23 turns over, and it can remain to 2 one axial power of internal spline clutch pawl; When the pawl of internal spline clutch pawl 2 during over against the groove of slip copper sheathing clutch dog chain wheel 3, the tension force of tension spring 15 just can make their rapid combinations, and power obtains transmission.When needs cut off power, only need clutch operating lever 20 is shifted onto " leaving " position of control panel 17, return spring 14 (receiving certain pretightening force all the time) can be given the power of 23 1 disengagements of fork portion of shift fork equally through the revoliving arm 24 of shift fork.The whole operation process all connects through flexible member, effectively reduces to impact and noise.
2. when the gear of clutch is three
See Fig. 7 and Fig. 8.Key connects driving gear II 5 and obtains can being with spline transmission shaft 8, internal spline double end clutch pawl 7 to rotate behind the power; Slip copper sheathing clutch blade tooth wheel I 6 is connected driving gear III10, slip copper sheathing driving gear II 9, and be connected driving gear IV 13 with key are constant mesh gear pairs with key; Drive sprocket 11 is output sprockets, and it receives the power of output elements such as chain and pass to key connection driving gear III10 to this power through transmission shaft 12 to be connected driving gear IV 13 with key.
When clutch operating lever 19 is in " neutral gear " of control panel 17; Internal spline double end clutch pawl 7 does not combine with slip copper sheathing driving gear II 9 with slip copper sheathing clutch blade tooth wheel I 6, and slip copper sheathing clutch blade tooth wheel I 6 is motionless with slip copper sheathing driving gear II9.
When third gear clutch operating lever 19 is in " one grade " of control panel; Clutch line 16 is being with tension spring 15 to stir internal spline double end clutch pawl 7 to a side; It is combined with slip copper sheathing clutch blade tooth wheel I 6; Slip copper sheathing clutch blade tooth wheel I 6 obtains power, begins be with key to connect driving gear III10 running, and power obtains transmitting.
And when third gear clutch operating lever 19 is in " second gear " of control panel; Clutch line 16 loosens; Return spring 14 is stirred internal spline double end clutch pawl 7 to opposite side, and it is combined with slip copper sheathing driving gear II 9, and slip copper sheathing driving gear II 9 obtains power; Be with key to connect driving gear IV 13 runnings, power obtains transmitting.
If needs are arranged, can change the clutch pawl into a plurality of feather keys that can in axial groove, slide, combine respectively with more gear or sprocket wheel, thus the embedded clutch of the more gears of realization.
Realize the be flexible coupling key point of embedded clutch for clutch control mechanism of the present invention:
. at first accurate Calculation internal spline clutch pawl or internal spline double end clutch pawl are confirmed the basic data of mechanism in the axial stroke of each gear;
. the height of engaging lug on the turning radius of the revoliving arm of design shift fork, the design clutch operating lever converts axial stroke to the amount of tension of spring and the stroke of clutch line; To note the relation between each stroke especially, control stroke size, the stroke of engaging lug must be greater than the stroke of shift fork revoliving arm on the clutch operating lever.
. in the scope that stroke allows, calculate the revoliving arm force-bearing situation under the different amount, choose optimal case, confirm the angle between the fork portion of revoliving arm and shift fork of shift fork;
The turning radius of shift fork revoliving arm need be according to stroke and the spatial position decision of clutch pawl on axle, and the revoliving arm turning radius in two gear mechanisms among the present invention is 24mm (the revoliving arm turning radius in three gear mechanisms is 36.4mm).
. confirm the position of clutch thread fixing plate in integral device;
. select and verify return spring, tension spring parameter for use; The initial tensile force of calculating spring, maximum functional pulling force etc.; The rigidity and the amount of deformation of two springs of strict design; And make the rigidity of two kinds of springs and amount of deformation that a certain distance arranged, with the pulling force that guarantees spring the clutch pawl is combined and disengagement smoothly;
. calculate and regulate the fixed position of clutch line screw rod on equipment, to guarantee confirming and realization of each gear.
