Advantage of making a concerted effort drive hub of the present utility model is, the wheel hub that is provided mainly is provided with two drivies shaft sleeve in the center shaft of a hub shell, respectively be provided with a transmission bevel gear on two drivies shaft sleeve, be provided with between two transmission bevel gears two and Vertical Meshing and with the passive bevel gear of hub shell interlock.Be respectively arranged with transmission gear and the chain drum of interlock on the two transmission bevel gears to motor and foot-driven lever.Can allow the cycling person trample thus and possess the effect of making a concerted effort with the transmission effect of motor power transmission with manpower, thereby further enlarge the use elasticity and the usefulness of Electrical Bicycle, and the situation of avoiding manpower to trample stretcher and causing a motor and gear to be damaged is to keep the normal use of bicycle.
Further specify technical characterictic of the present utility model and purpose below in conjunction with accompanying drawing.
Brief Description Of Drawings:
Fig. 1: three-dimensional exploded view of the present utility model.
Fig. 2: combination generalized section of the present utility model.
Fig. 3: the partial cutaway schematic of the utility model operation embodiment.
Please cooperate referring to Fig. 1,2.By seeing among the figure, the bicycle driven wheel hub of making a concerted effort provided by the utility model consists predominantly of a cylindric hub shell 10 that is arranged on the bicycle rear shaft, hub shell 10 is provided with several and is the radial steel wire 11 of intersection, can combine with the wheel rim of trailing wheel by steel wire 11, to constitute the trailing wheel of bicycle.The central authorities of hub shell 10 are provided with a center shaft 12 that axially runs through hub shell 10,10 of the two ends of center shaft 12 and hub shell are arranged with a drive shaft sleeve 14,15 that penetrates hub shell 10 two ends respectively, and be respectively arranged with bearing 142,144,146,152,154,156 between drive shaft sleeve 14,15 and hub shell 10 and the center shaft 12, allow two drivies shaft sleeve 14,15 be axial rotation with respect to hub shell 10 and center shaft 12 respectively.12 set bearings 144,154 of two drivies shaft sleeve 14,15 and center shaft are unilateral bearing.
Two drivies shaft sleeve 14,15 stretch into hub shell 10 in-to-ins one end and are respectively arranged with a parallel relative transmission bevel gear 16,17, two transmission bevel gears 16,17 and 14,15 of two drivies shaft sleeve close with bond, and transmission bevel gear 16,17 can be rotated with drive shaft sleeve 14,15.Be provided with the two passive bevel gears 18,19 that are the Vertical Meshing state respectively with two transmission bevel gears 16,17 between the two transmission bevel gears 16,17, and the passive angular wheel shaft 182,192 of two passive bevel gears 18,19 is arranged in vertically on the periphery of hub shell 10.Passive angular wheel shaft 182,192 and 10 of hub shell are provided with bearing 184,194, make 10 of passive angular wheel shaft 182,192 and hub shell can be axial rotation relatively.
In addition, two drivies shaft sleeve 14,15 are positioned on the position in hub shell 10 outsides and are respectively arranged with a chain drum 26 and transmission gear 24.Wherein chain drum 26 with on chain and the cycle frame with the chain drum of stretcher crankshaft drive interlock mutually, transmission gear 24 interlock that then is meshed with one and the coaxial gear 22 of motor 20, and transmission gear 24 cooperates belt pulley with the also available belt of the drive connection of 22 of gears, or chain cooperates chain drum to replace.
So, when the stretcher on user's treadled cycle vehicle frame, can come transmission chain drum 26 to rotate, rotate by chain drum 26 transmission drive shafts cover 15 again, and then drive transmission bevel gear 17 coaxial rotation with drive shaft sleeve 15 by chain.If this moment is starter motor 20 not, another drive shaft sleeve 14 keeps quiescence on hub shell 10 center shafts 12, so when the drive shaft sleeve 15 of tool chain drum 26 rotates, can drive two passive bevel gear 18,19 rotations that are engaged with by transmission bevel gear 17, and make two passive bevel gears 18,19 do the revolution rotation along two transmission bevel gears, 16,17 peripheries.Just can drive hub shell 10 and rotate by passive angular wheel shaft 182, bearing 184 thus, and then drive trailing wheel, bicycle is advanced with certain speed rotation.
When user's starter motor 20, the power of motor 20 can be passed on another drive shaft sleeve 14 of center shaft 12 by gear 22 and transmission gear 24, and drives 16 rotations of transmission bevel gear by drive shaft sleeve 14.This moment is not when rotating as if another drive shaft sleeve 15 that chain drum 26 is set, be that the user is not during the stretcher on the treadled cycle, this transmission bevel gear 16 still can drive two passive bevel gears 18,19 and revolve round the sun along two transmission bevel gears, 16,17 peripheries, rotate with certain speed and drive hub shell 10, bicycle is advanced.So just can utilize the power of motor 20 to drive bicycle and advance, reach the effect of saving user's muscle power.
When user's starter motor 20 and when trampling stretcher simultaneously, because two drivies shaft sleeve 14,15 on the center shaft 12 are respectively transmission gear 24 and 26 transmissions of chain drum, two drivies shaft sleeve 14,15 can not influence each other when rotating, and two drivies shaft sleeve 14,15 and 12 of center shafts are provided with unilateral bearing, rotate so two drivies shaft sleeve 14,15 can be distinguished in the same way because of the power that motor 20 and manpower are trampled.This moment, two transmission bevel gears 16,17 can drive two passive bevel gears 18,19 rotations with different velocities of rotation simultaneously, and allow two passive bevel gears 18,19 make revolution motion with certain resultant velocity along the periphery of two transmission bevel gears 16,17, and then the drive bicycle advances.Find through the reality test, if the number of teeth of two transmission bevel gears 16,17 equates, and the number of teeth of two passive bevel gears 18,19 also equates, utilize motor 20 electric power or manpower transmission to make 16,17 other velocities of rotation of two transmission bevel gears be A, drive the speed that passive bevel gear 18,19 rotates along transmission bevel gear 16,17 peripheries, be that speed that hub shell 10 is rotated is when being B, when making two transmission bevel gears, 16,17 velocities of rotation all reach A with motor 20 electric power and manpower simultaneously, two passive bevel gears 18,19 then are 2B along the speed of two transmission bevel gears, 16,17 peripheries revolution.Promptly when simultaneously trampling and during motor 20 driven by power, can allowing bicycle reach the two-fold speed of advance with manpower.Simultaneously, if the manpower speed of trampling is A1 and speed that motor 20 drives is A2, and during A1+A2=2A, the velocity of rotation of hub shell 10 still can be 2B, promptly by manpower and motor 20 electric power the transmission agency that produces respectively can reach the effect of addition with joint efforts, so can allow the user look different user demand with manpower, electric power, or the synchronously driven mode of manpower electric power drives bicycle and advances, and adjust the transmission ratios that electric power and manpower are trampled according to physical state itself, to improve the comfort feature and the whole effective utilization of bicycle use.
