The utility model relates to a kind of cardan wheel, is arranged on the casing bottom of battery-driven car, comprises castor, foot wheel carrier, clutch shaft bearing, the second bearing and versatile spindle; Wherein, described castor is arranged on described foot wheel carrier by wheel shaft, the clutch shaft bearing that described clutch shaft bearing is arranged on described foot wheel carrier top is indoor, described second bearing is arranged in the second bearing chamber of described casing bottom, described versatile spindle from top to bottom successively through described second bearing, clutch shaft bearing, foot wheel carrier, and is fixed on described foot wheel carrier by fastener.Beneficial effect: adopt double-deck bearing to carry out transmission cardan wheel, makes cardan wheel freely to rotate smoothly, and described cardan wheel is owing to being arranged on described casing bottom, takies volume little, detachably, is convenient to maintenance; Adopt the foot wheel carrier with obliquity structure, turn to conveniently; Foot wheel carrier cover can the actv. contamination by dust that prevents clutch shaft bearing to be subject to, increases the service life.
Description
Technical field
The utility model relates to Electrical Bicycle technical field, especially relates to a kind of cardan wheel.
Background technology
At present, Electrical Bicycle because not needing manpower Direct driver when it uses more laborsaving and speed and be subject to popular favor.Folding electric bicycle is free to collapsible due to it simultaneously, conveniently transports and carries and increasingly become market new lover.The Chinese patent CN102285414A< box-type foldable electric bicycle > of the present inventor's application disclose a kind of folding after face shaping rule and attractive in appearance, smooth surface and small volume, collect and carry box-type foldable electric bicycle all easily.But, after this box-type foldable electric bicycle is folding, because universal caster wheel is arranged on vehicle frame framework, easily there is unbalance stress, cause the wearing and tearing of casing bottom, take volume large simultaneously, and not quick detachable, maintenance is inconvenient.
The utility model provides a kind of cardan wheel being arranged on bottom half, rotates inconvenience, take volume large to solve universal caster wheel of the prior art, and not easily detachable problem.
Utility model content
The utility model is that the universal caster wheel solving prior art rotates inconvenience, take volume large, and not easily detachable problem, a kind of cardan wheel is provided, is arranged on the casing bottom of battery-driven car, double-deck bearing is adopted to carry out transmission cardan wheel, cardan wheel can freely be rotated smoothly, and described cardan wheel is owing to being arranged on described casing bottom, takies volume little, detachably, maintenance is convenient to.
The technical matters that the utility model solves realizes by the following technical solutions:
A kind of cardan wheel, is arranged on the casing bottom of battery-driven car, comprises castor, foot wheel carrier, clutch shaft bearing, the second bearing and versatile spindle; Wherein, described castor is arranged on described foot wheel carrier by wheel shaft, the clutch shaft bearing that described clutch shaft bearing is arranged on described foot wheel carrier top is indoor, described second bearing is arranged in the second bearing chamber of described casing bottom, described versatile spindle from top to bottom successively through described second bearing, clutch shaft bearing, foot wheel carrier, and is fixed on described foot wheel carrier by fastener.
As preferred technical scheme, the bottom of described foot wheel carrier is made up of the support that two form inverted U-shaped.Further, described support has certain inclination angle, and described inclination angle is 0 ~ 60 degree, so that the steering operation of wheel.
As preferred technical scheme, the top of described foot wheel carrier is also provided with foot wheel carrier cover, avoids the clutch shaft bearing be arranged on described foot wheel carrier to be subject to contamination by dust.
As preferred technical scheme, described foot wheel carrier cover and casing bottom are structure as a whole.
The beneficial effect that the utility model has is: (1) adopts double-deck bearing to carry out transmission cardan wheel, and cardan wheel can freely be rotated smoothly, and described cardan wheel is owing to being arranged on described casing bottom, takies volume little, detachably, is convenient to maintenance;
(2) adopt the foot wheel carrier with obliquity structure, turn to conveniently;
(3) foot wheel carrier cover can the actv. contamination by dust that prevents clutch shaft bearing to be subject to, increases the service life.
Accompanying drawing explanation
In order to be illustrated more clearly in embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the mounting structure schematic diagram of a kind of cardan wheel of the utility model;
Fig. 2 is the integral structure schematic diagram of a kind of cardan wheel of the utility model;
Fig. 3 is the structural representation of the foot wheel carrier of a kind of cardan wheel of the utility model.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
Shown in seeing figures.1.and.2, a kind of cardan wheel, is arranged on the casing bottom 1 of battery-driven car, comprises castor 2, foot wheel carrier 3, clutch shaft bearing 4, second bearing 5 and versatile spindle 6; Wherein, castor 2 is arranged on foot wheel carrier 3 by wheel shaft, clutch shaft bearing 4 is arranged in the clutch shaft bearing room 7 at foot wheel carrier 3 top, second bearing 5 is arranged in the second bearing chamber 8 of casing bottom 1, versatile spindle 6 is from top to bottom successively through the second bearing 5, clutch shaft bearing 4, foot wheel carrier 3, and being fixed on foot wheel carrier 3 by fastener, the present embodiment adopts double-deck bearing to carry out transmission cardan wheel, and cardan wheel can freely be rotated smoothly.
In order to prevent dust to the pollution of clutch shaft bearing 4, the top of foot wheel carrier 3 is also provided with foot wheel carrier cover 9, avoids the clutch shaft bearing 4 be arranged on foot wheel carrier 3 to be subject to contamination by dust, extends its service life, preferably, foot wheel carrier cover 9 and casing bottom 1 are structure as a whole.
With reference to shown in Fig. 3, the bottom of foot wheel carrier 3 is made up of the support 10 that two form inverted U-shaped.Further, support 10 has certain inclination angle theta, and inclination angle theta is 0 ~ 60 degree, so that the steering operation of wheel.
More than show and describe groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
