Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail.
Embodiment 1
A kind of hollow wheel hub transmission device, as Figure 1-4, is generally used for the balance truck with longer car handle, or there is the vehicle of similar structures, because the wheel of this type of vehicle is comparatively large, and have a longer handle, therefore wheel easily produces deflection, affects driving efficiency.The present embodiment describes a kind of hollow wheel hub transmission device, comprise a upper surface 101 as pedal vehicle body 100, be arranged at vehicle body 100 two ends and the annular wheel hub 200 be in transmission connection with the driven unit 102 being arranged at vehicle body 100 inside, the tire 300 in outside being arranged at described annular wheel hub 200 and the bracket component that is arranged at inside annular wheel hub 200.Upper surface is made up of the upper cover of vehicle body 100, forms the cavity that can hold driven unit 102 between itself and the lower casing of vehicle body 100.Driven unit 102 comprises motor and battery, but in other cases, also can use the device of other types driven by energy.Tire 300 can be solid, and also can be aerated air core tyre, other forms of tire also can.
Wherein, on the radial section of described annular wheel hub 200, described tire 300, annular wheel hub 200 and bracket component 400 are arranged in order from outside to inside.
Described annular wheel hub 200 at least comprises one by the transmission of power of driven unit 102 to the driving face 201 of tire 300 and tire snap-latch surface 202; Described tire snap-latch surface 202 is for fixed tire 300.Alternatively, driven unit 102 is by transmission gear be arranged on tooth bar on driving face 201 as transmission device.And at tire snap-latch surface 202, by the rubbing effect fixed tire of snap-latch surface, the technology difficulty that tire is installed can be reduced.
Further, described bracket component 400 is fixedly connected with vehicle body, for preventing the laterally offset of annular wheel hub 200 in rotation process.
Described annular wheel hub 200 is on its circumferential bearing of trend, and the curved surface along tire 300 extends to form support portion 203 towards the both sides of annular wheel hub 200 respectively, and support portion 203 is for supporting the transmission of power of driving face 201.
Further, described support portion 203 at least comprises a vertical wall 204, and described vertical wall 204 extends along the radial direction of described annular wheel hub 200, and the both sides of annular wheel hub 200 listed in radial directions by vertical wall 204; One end towards driven unit 102 of vertical arm is the driving face 201 of annular wheel hub 200, in other words, vertical wall 204 is begun by driving face 201, radial direction along annular wheel hub 200 extend vertically until with tire 300 closed position, one end of the close driving face 201 of vertical wall 204 is connected with other parts of annular wheel hub 200.Further, as the optional scheme of one, other parts except vertical wall 204 and the vertical wall 204 of annular wheel hub 200 are roughly in vertical distribution, such form is that the Vertical dimension intensity that can utilize vertical wall 204 improves driving efficiency, and can reduce difficulty technique being formed snap-latch surface.
In addition, the end face towards tire 300 of the inner side surface and support portion 203 that are positioned at the vertical wall 204 of annular wheel hub 200 both sides forms described tire snap-latch surface 202, by shape, tire snap-latch surface 202 is a structure being close to groove, a part for tire snaps in groove fixing, and vertically the end face be close to tire 300 of wall 204 can when vehicle run-off the straight, use as an interim fulcrum, can prevent tire 300 from deviating from by tire snap-latch surface 202 by youngest brother.
The interior side ring surface 205 of described annular wheel hub 200 is also provided with the protruding rail 206 that the circumferential direction along described annular wheel hub 200 extends; The side of described protruding rail 206 or both sides are driving face 201.Protruding rail 206 both can limit the movement of the axial direction along annular wheel hub 200 of the gear of driven unit to a certain extent, also the structure of annular wheel hub 200 can be strengthened, particularly itself and vertical wall 204 form triangle fulcrum, improve the structural strength of whole annular wheel hub 200.
Further, in order to support whole annular wheel hub 200 and tire 300, described bracket component 400 extends along the circumferential direction of described annular wheel hub 200 and covers side ring surface 205 in annular wheel hub 200; Bracket component 400 extends to form left and right bracing frame 401,402 to the both sides of described annular wheel hub 200 and covers annular wheel hub 200 completely.Because annular wheel hub 200 lacks wheel shaft, the rolling track of annular wheel hub 200 therefore can only be limited by annular wheel hub 200 and the laminating of the inner side surface of bracket component 400.Thus, with the present embodiment, the vertical wall 204 of annular wheel hub 200 and protruding rail 206 are as main fulcrum, its effect offset about having arrived the annular wheel track of restriction, other parts of annular wheel hub 200 directly do not contact with between bracket component 400, can reduce friction, improve driving efficiency.
Described bracket component 400 also comprises the lug boss 403 being arranged at the circumferential direction along annular wheel hub 200 between left and right bracing frame 401,402 and extending; Described lug boss 403 is towards the reverse extension of the bearing of trend of left and right bracing frame 401,402.The protrusion direction of lug boss 403 is consistent with the protrusion direction of the protruding rail 206 of annular wheel hub 200, meanwhile, in technique, and the position of the adhesive surface in the lug boss 403 of bracket component 400 or left and right two-part bracket component 400 adhesion process.
Further, the top of described protruding rail 206 is close in the bottom of described lug boss 403, fully the pressure from annular wheel hub 200 can be distributed to equably the various piece of whole bracket component 400 by protruding rail 206.
Although bracket component 400 can be any position with the junction of vehicle body 100, but as a kind of preferred scheme, described bracket component 400 and the junction of vehicle body 100 are positioned at the position that described driving face 201 contacts with described driven unit 102, specifically, this position is positioned at the side on the lower side of annular wheel hub 200, also be the position that the transmission gear of driving device and the tooth bar of driving face are meshed simultaneously, contribute to the left and right skew that minimizing tire 300 produces in the form process of vehicle.
Thus, the present embodiment also comprises a kind of balance truck obtained according to above-mentioned hollow wheel hub transmission device.
In a word, the foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
