Wheel drives flywheel turns, and owing to the flywheel of bicycle body-building device is not in contact with ground, therefore flywheel exists bigger centrifugal force, by
Often slowing down in exercise routine, accelerate, the speed difference that there is speed difference between sprocket wheel and flywheel easily makes sprocket wheel and flywheel
Between produce loosen, cause sprocket wheel to be deviate from time serious.
Summary of the invention
Therefore, it is necessary to provide the bicycle body-building device solving the problems referred to above.
A kind of bicycle body-building device, the flywheel being arranged on vehicle frame including vehicle frame and rotation, described flywheel includes wheel hub,
Spoke, wheel shaft and from belt pulley, described wheel hub, spoke, wheel shaft and being formed in one from belt pulley.
Further, described vehicle frame includes front fork, and described front fork is provided with support, and described support arranges a U-type groove,
Described flywheel is arranged in U-type groove by pivotally supported.
Further, described pivot is a mandrel, and described mandrel is fixed on support, described flywheel turns sheathed
On mandrel.
Further, described bicycle body-building device also includes that main pulley and belt, described belt are V-shape belt, flat
Belt, the one in O type belt or synchronous gear belt.
Further, described belt is synchronous gear belt.
Compared with prior art, the wheel hub on flywheel of the present utility model, spoke, wheel shaft and being integrated into from belt pulley
Type so that wheel hub, spoke, wheel shaft and being greatly promoted from belt pulley overall construction intensity, will not be because of the plus-minus in exercise routine
Speed, causes loosening from generation between belt pulley and wheel shaft or producing between each assembly of flywheel loosening.

Detailed description of the invention
Referring to Fig. 1 to Fig. 2, this utility model provides a kind of bicycle body-building device, including vehicle frame 10, flywheel 20.
Described vehicle frame 10 includes front fork, and described front fork generally includes the column being vertically arranged a pair, at column
Middle part arranges support 11 for Flywheel 20, common, and described support 11 arranges a U-type groove, and described flywheel 20 leads to
Crossing pivotally supported being arranged in U-type groove, described flywheel 20 can be structure as a whole with pivot or be separate type structure,
When described flywheel 20 is structure as a whole with pivot, described pivotally supported it is arranged on support 11.Described flywheel 20
When being separate type structure with pivot, as in the present embodiment, described pivot is a mandrel 12, and described mandrel 12 passes through mandrel
The nut at 12 two ends is fixed on support 11, and what described flywheel 20 rotated is set on mandrel 12, it is preferred that flywheel 20 with
It is also provided with bearing, so that flywheel 20 rotates more flexibly on mandrel 12 between described mandrel 12.
Described flywheel 20 includes wheel hub 21, spoke 22, wheel shaft 23 and take turns 24 from belt 30, and this wheel hub 21 is a circular wheel
Shape, described wheel shaft 23 is a cylinder, and described wheel shaft 23 rotary centerline overlaps with described wheel hub 21 center of rotation, if dry plate
Shape spoke 22 has the first end and the second end, and described first end is connected with wheel hub 21 medial surface, outside described second end is with wheel shaft 23
Side connects, thus wheel hub 21, spoke 22, wheel shaft 23 are connected into an entirety, and spoke 22 described in the present embodiment is
Three, it is possible to understand that described spoke 22 can also only only one of which, or two and more, it is possible to understand that,
Spoke 22 described in spoke 22 described in the present embodiment can also be other cross sectional shapes, the tabular being not limited in the present embodiment.
Described wheel shaft 23 side is provided with from belt pulley 24, described from belt pulley 24 be a cylinder, its center of rotation and wheel shaft
23 centers of rotation overlap, and its outer surface is provided with belt 30 groove, is used for accommodating belt 30.It should be understood that it is described from belt
Taking turns 24 external diameters can be identical or different with wheel shaft 23 external diameter.Described wheel shaft 23 with in belt pulley 24, be additionally provided with axis hole 25, use
In being set in outside mandrel 12 by axis hole 25, flywheel 20 is made to rotate around mandrel 12 centrage.Described wheel hub 21, spoke 22, wheel
Axle 23 and being formed in one from belt pulley 24, it will be understood that wheel hub 21, spoke 22, wheel shaft 23 and overall from from belt pulley 24
Material is machined out making, and as car, milling, mill etc. machine, described material can use existing, such as metal material, wood
Material, plastic or other material.
It should be understood that described bicycle body-building device also includes main pulley 40 and belt 30, in order to by main belt
Wheel 40 and belt 30 drive and rotate from belt pulley 24, so that flywheel 20 rotates, it is possible to understand that, owing to driving flywheel 20 to rotate
