Specific embodiment
Fig. 1 shows a specific embodiment of the application this internal rotor wheel hub motor, with traditional internal rotor wheel hub electricity
Machine identical is, it also includes one-way clutch 5, hub shell 1, the axis 2 being rotatably disposed in this hub shell 1 (or claim
Rotating shaft), the axis tooth 2a that is fixedly installed on described axis 2 and is in transmission connection with described hub shell 1, be arranged in described axis
The rotor 3 of 2 peripheries, it is arranged in the stator 4 of described rotor 3 periphery, rotor 3 and stator 4 are all contained in described hub shell 1
Portion.
The key improvements of the present embodiment are: this motor is connected to described axis 2 and institute by sheathed for described one-way clutch 5
State between rotor 3.
The rotor of traditional internal rotor wheel hub motor is completely fixed on axis, and the present embodiment utilizes one-way clutch
5 rotor 3 one-way locking is fixed on axis 2, and rotor 3 and axis 2 are no longer completely fixed.
It is arranged such so that one-way clutch 5 and the public same section of bearing space of rotor 3, this wheel hub motor need not be special
For the full-scale axially mounted space of one-way clutch 5 additional, so that the axial dimension of this wheel hub motor greatly reduces,
Can be arranged on less cycle frame.
With some traditional one-way clutch identicals be, the above-mentioned one-way clutch 5 that the present embodiment is adopted also include from
Clutch inner ring and the clutch outer of this clutch inner ring one-way locking.In the present embodiment, described clutch inner ring fixation is sheathed
In described axis 2 periphery, described clutch outer fixation is set in described rotor 3 radially inner side.
In general, the axial dimension of rotor 3 is greater than the axial dimension of one-way clutch 5, based on this feature, this reality
Apply the axially inner side that above-mentioned one-way clutch 5 is all contained in rotor 3 by example, so that this one-way clutch 5 takies completely
The axial dimension of this wheel hub motor.
In the present embodiment, described axis tooth 2a and described axis 2 are structure as a whole.
This wheel hub motor is also included for this internal rotor wheel hub motor is connected on vehicle frame and coaxially arranged left company
Spindle 6 and right connecting shaft 7, a part for described left connecting shaft 6 and right connecting shaft 7 stretches in described hub shell, another part
Stretch out outside described hub shell, and left connecting shaft 6 and right connecting shaft 7 are respectively passed through bearing 8 (this bearing 8 is deep-groove ball axle
Hold) it is rotatably connected with described hub shell 1, described axis 2 is coaxially arranged with described left connecting shaft 6 and right connecting shaft 7.
Described axis tooth 2a and described hub shell 1 are in transmission connection by gear drive.
Described gear drive includes the nylon gear 9 being connected with described axis tooth 2a engagement, with described nylon gear 9
The ring gear 1c that engagement connects, described nylon gear 9 is rotatably connected in institute by bearing 8 (this bearing 8 is also for deep groove ball bearing)
State in left connecting shaft 6, described ring gear 1c is fixedly installed on described hub shell 1.
Described hub shell 1 by the outer cover body 1a being linked together by screw 11 (this screw is machine screw with oval countersunk fillister head) and
Shell end cap 1b is constituted, and described ring gear 1c is shaped on described shell end cap 1b.
Described hub shell 1 is provided with screw 11 (this screw is sunk screw) and is fixed in described left connecting shaft 6
Stator support 10, described stator 4 is fixed on this stator support 10.Described stator support 10 and the front support of described axis 2
There is bearing 8 (this bearing 8 is also deep groove ball bearing).
During practical application, by left connecting shaft 6 and right connecting shaft 7 nut check be fixed on cycle frame front fork or after
On fork.Under electric model, electrical power and rotor driven 3 rotates clockwise in Fig. 1 left view direction, rotor 3 pass through unidirectional from
Clutch 5 drives axis 2 rotating in same direction (now one-way clutch is in locking state), and the axis tooth 2a on axis 2 drives nylon
Gear 9 rotates counterclockwise in Fig. 1 left view direction, and nylon gear 9 drives the ring gear 1c being engaged with again in Fig. 1 left view direction
Also rotate counterclockwise, and then drive hub shell 1 also to rotate counterclockwise in Fig. 1 left view direction, hub shell 1 passes through spoke
Drive vehicle wheel rotation, vehicle forward.Under people's force mode, people steps on the foot-operated chain-driving hub shell 1 that passes through and makees in Fig. 1 left view direction
Rotate counterclockwise, hub shell 1 drives vehicle wheel rotation by spoke, makes vehicle forward.The now ring gear 1c in hub shell
Nylon gear 9 is driven to rotate counterclockwise in Fig. 1 left view direction, nylon gear 9 drives axis 2 left in Fig. 1 by axis tooth 2a
Apparent direction rotates clockwise, and now the inner ring of one-way clutch and outer ring are in released state, therefore the rotation of axis 2 will not
Pass to rotor 3, rotor 3 will not be followed axis 2 and be rotated, and greatly reduce advance resistance.
In order to prevent other motor components that one-way clutch 5 outer ring of this clutch (especially) is with its axial both sides
(two bearings of clutch shaft both sides to the left and right in such as Fig. 1) come in contact interference, and lead to vehicle sliding or manpower to be ridden
During increase vehicle forward resistance, the present embodiment is arranged with axis 2 and is located at the axial both sides of this one-way clutch 5 respectively
Sliding gasket 12, sliding gasket 12 adopts the very little material of coefficient of friction, and it is by zero of one-way clutch 5 and axial both sides
Part separates 0.4～0.5mm, is prevented effectively from the generation of the problems referred to above.
Certainly, above-described embodiment is only technology design and the feature that the application is described, its object is to make people much of that
Solution present context is simultaneously implemented according to this, can not limit the protection domain of the application with this.All according to the application major technique
Equivalent transformation or modification that the spirit of scheme is done, all should cover within the protection domain of the application.
