The specific embodiment
Be the effect that can further understand the purpose of this utility model, feature and be reached, below lift preferred embodiment of the present utility model now, and after cooperating graphic being described in more detail in;
At first, see also Fig. 1 to Fig. 4, the utility model one preferred embodiment provides the ride-on vehicle of improvement drive wheel structure, includes:
One vehicle frame 10 has the place ahead that a support body 11, two pivoted poles 13 promptly are hubbed at this support body 11, and these pivoted pole 13 bottoms are provided with a pivot portion 15.
One crank shaft 20, has an axostylus axostyle 21 and is the pivot portion 15 that is hubbed at this vehicle frame 10 and free to rotate, one joint portion 23 is to be located at this axostylus axostyle 21 middle periphery desired location length for a spiro union portion, two pivots 25 respectively are arranged in this axostylus axostyle 21 2 sides with one heart, and two cranks connect two ends that portion 27 is located at this axostylus axostyle 21 respectively.
One unidirectional rotation device 30, promptly be to be a kind of unilateral bearing assembly set, having an internal axle sleeve 31, to be formed with a spiro union portion 32 are joint portions 23 of being located at this crank shaft 20 for a screw spiral shell, but an outer shaft 35 is to roll part 39 and unidirectional rotation (present embodiment is to rotate forward) only relative to 31 of this internal axle sleeves device is some, one joint portion 36 is formed at this outer shaft 35 periphery desired locations, and this joint portion 36 is located in plurality of fixed hole 37.
Two wheel hubs 40, be left and right sides outer shaft 35 2 sides that are installed in this unidirectional rotation device 30, this each wheel hub 40 is formed with the joint portion 36 that a joint portion 41 is engaged in this unidirectional rotation device 30, one trepanning 42, plurality of fixed hole 43 can rivet 83 or bolt wear fixed orifice 37 combinations of this unidirectional rotation device 30, one exntension tubs, 45, one wheels meet portion 47 and offer and somely connect hole 48, and are formed with a Shen nest 49 in the relative outside.
One first wheel 50, have some spokes 51 be the steel bar shape be arranged in this wheel hub 40 respectively to connect hole 48, one wheel bodys 53 are the peripheries that are arranged in each spoke 51, a carcass 55 is located at the periphery of this wheel body 53.
Two crank pedal groups 60 respectively have each crank that a crank 61 is fixed in this crank shaft 20 and connect free end the trampling for the human foot that portion's 27, one pedals 65 are hubbed at this crank 61 free to rotately.
2 second wheels 70, respectively have a wheel body 71 and be the desired location, support body 11 rear end that is hubbed at this vehicle frame 10 about two sides.
The start of present embodiment is described as follows now;
At first, when trampling this pedal 65 forward, but this first wheel 50 of these unidirectional rotation device 30 interlocks is rotated, therefore reach the state that advances that drives by this crank shaft 20; On the contrary, this unidirectional rotation device that can rotate backward then is idle running and can not move this first wheel 50 and rotate.
When trampling when stopping, trample this crank pedal group 60 after can be arbitrary to any one favourable application of force angle position, and the peak power that foot tramples can obtain human body and drive the time can drive this first wheel 50 again, makes car continue to advance forward.
Can learn that by this embodiment the utility model can provide free effect of trampling backward when the angle of the inconvenient application of force or the bad application of force, to turn to suitable angle, promptly can begin to trample by best application of force state.
In addition, owing to need sometimes to advance forward with the mode that pushes away, this crank shaft 20 can't rotate with crank pedal group 60 thereupon in the structure of the present utility model, can avoid foot constantly along with the disappearance of rotating, and do not have the possibility that the crank that is rotated and pedal are wounded, thereby have preferable safety.
The another kind of structure of this wheel hub of the utility model is two wheel hubs of previous embodiment can be combined as a whole, and forms a joint portion jointly, and combine with the locking of unidirectional rotation device with bolt or rivet.
In addition, this wheel hub of aforementioned the utility model, it can coat the joint portion that is arranged in this unidirectional rotation device by plastic jetting forming again.
In addition, this unidirectional rotation device is to can be any unidirectional rotation device known today in the utility model, and in addition as single direction ratchet or the like, the creation purpose of its same attainable cost utility model should belong to the scope that the utility model is advocated.
Comprehensive above embodiment the utlity model has following effect;
1. the ride-on vehicle of the utility model improvement drive wheel structure directly drives wheel when it can make crank and pedal trample forward, also turns round at preposition, conveniently to begin to trample the application of force.
2. the ride-on vehicle of the utility model improvement drive wheel structure, its crank and pedal can be when vehicle promote to advance, and not with the rotation of wheel, and can avoid the unnecessary activity of foot and take into account safety.
3. the utility model is improved the ride-on vehicle of drive wheel structure, the effect that the wheel hub of its combined can provide wheel and the convenient combination of crank shaft to change.
