Wherein, which is between a full speed position, a deceleration position and a neutral, when the adjusting hand
When cylinder 8 is in full speed position, which directly drives protecgulum fan block 33, when the adjusting hand cylinder 8 is in deceleration position
When, which directly drives fluted disc fan block 72, when the adjusting hand cylinder 8 is in neutral, the driving fixture block 11
It is detached from protecgulum fan block 33 and fluted disc fan block 72, hereinafter will be further illustrated.
How to be used the following detailed description of child's tricycle forerunner wheel.
As shown in Figure 18 and Figure 19, which is in full speed position, at this point, under the action of compression spring 14, it is whole
A driving fixture block 11 is slided into close to the side of protecgulum 3 so that the fixture block of a driving fixture block 11 protrudes 112 and is embedded into protecgulum 3
Protecgulum is fanned between block 33.When child's pushes pedals 42, entire drive component 9S directly drives the protecgulum of protecgulum 3 to fan block 33 and carries out
Rotation, then, entire wheel body are travelled forward with drive component 9S with identical speed.It should be noted that at this point, adjusting hand
The limit baffle ring 82 of cylinder 8 has resisted the inside of protecgulum 3.
As shown in Figure 20 and Figure 21, user, which rotates clockwise, adjusts hand cylinder 8, is connect with first using hand cylinder screw thread 811
The cooperation of screw thread 1221, the entire hand cylinder 8 that adjusts continue deeper into and press driving fixture block 11 always, and compression spring 14 is extruded, together
When, driving fixture block 11 is slided along sliding notch 1211 towards the direction of power fluted disc 7, until the fixture block of driving fixture block 11 protrudes
112 deviate from between the protecgulum of protecgulum 3 fan block 33, at this point, the adjusting hand cylinder 8 is in neutral.On this position, when making
When user's pushes pedals 42, the power of entire drive component 9S is not transferred on wheel body.That is, working as parent's hand-held
When bar carries out child, the foot of child can be put on pedal 42, and the position of pedal 42 will not turn with the rotation that forerunner takes turns
It is dynamic, avoid forerunner's wheel or pedal from injuring the foot of child, the foot of child feels more comfortable.
As shown in figure 22 to figure 23, user, which continues to rotate clockwise, adjusts hand cylinder 8, and the entire hand cylinder 8 that adjusts continues deeper into
And pressing driving fixture block 11 always, compression spring 14 is pressed further by, and driving fixture block 11 continues court along sliding notch 1211
It is slided to the direction of power fluted disc 7, the limited ring dais 83 until adjusting hand cylinder 8 resists the card column main body 121 of driving card column 12
On end face.It is embedded between the fluted disc fan block 72 of power fluted disc 7 at this point, the fixture block of driving fixture block 11 protrudes 112.When child tramples
When pedal 42, entire drive component 9S directly drives the fluted disc of power fluted disc 7 to fan block 72 and is rotated, and power fluted disc 7 then will
Power is sequentially delivered to the rear cover tooth head 221 of the second transmission gear 6, the first transmission gear 5 and rear cover 2, and drive component 9S's turns
Speed is reduced, and then, entire wheel body is travelled forward with drive component 9S with lower speed.By adjusting rear cover tooth head
221, the transmission parameter, such as diameter, the number of teeth etc. of the first transmission gear 5 and the second transmission gear 6, to obtain ideal slow down
Than general 0.5-0.6 is proper.
It should be noted that can be referred to using the direction of arrow 813 when rotation adjusts hand cylinder 8, for example,
Arrow 813 is directed toward the first cue mark 301, the second cue mark 302 and third cue mark 303 and respectively represents full speed shape
State, idling conditions and deceleration regime.
It can be suitble to the child of different age group with the ride mode of unrestricted choice tricycle due to the use of person, it is safe.
Not limited to this, any change or replacement expected without creative work should all cover the guarantor in the present invention
