When child's tricycle forerunner wheel 1 is in primary speed-down mode, which drives a wherein power
Fluted disc 7,
When child's tricycle forerunner wheel 1 is in idle mode, which is detached from the power fluted disc 7,
When child's tricycle forerunner wheel 1 is in double reduction mode, which drives another power teeth
Disk 7,
When child's tricycle forerunner wheel 1 is in Full-Speed mode, which runs through the locking screw hole 251 and axis
Pipe jack 103.
How to be used the following detailed description of child's tricycle forerunner wheel.Clear explanation for convenience, here covers a pair
Body 2 is respectively labeled as lid 2A and lid 2B, and a pair of of power fluted disc 7 is respectively labeled as power fluted disc 7A and power fluted disc 7B.
As illustrated in figures 19 and 20, child's tricycle forerunner wheel 1 is in primary speed-down mode, at this point, in pressure bullet
It is entire that fixture block 11 is driven to slide into close to the side of power fluted disc 7B under the action of spring 14, so that the fixture block of a driving fixture block 11
Prominent 112 are embedded between the fluted disc fan block 72B of power fluted disc 7B.
When child's pushes pedals 42, entire driving assembly 9S directly drives the fluted disc of power fluted disc 7B to fan block 72B and carries out
Power is then sequentially delivered to the lid of the second transmission gear 6, the first transmission gear 5 and lid 2B by rotation, power fluted disc 7B
The revolving speed of tooth head 221, driving assembly 9S is reduced, then, entire wheel body with driving assembly 9S with lower speed forward
Movement.By adjusting the transmission parameter of lid tooth head 221, the first transmission gear 5 and the second transmission gear 6, such as diameter, the number of teeth
Deng to obtain ideal reduction ratio, general 0.5-0.6 is proper.
As shown in figure 21 and figure, child's tricycle forerunner wheel 1 is on idle mode.Specific operation process is as follows,
User pulls the pull ring 81 for adjusting bracing wire 8, adjusts the traction traction column cap 16 of bracing wire 8, then, driving 15 synchronous drive of screw rod is driven
Dynamic fixture block 11 is slided towards the direction of power fluted disc 7A, and compression spring 14 is extruded, until the fixture block prominent 112 of driving fixture block 11
Deviate from between the fluted disc of power fluted disc 7B fan block 72B.On this position, entire to drive when user's pushes pedals 42
The power of component 9S is not transferred on wheel body.That is, the foot of child can when parent's hand-held bar carries out child
To be put on pedal 42, the position of pedal 42 will not be rotated with the rotation that forerunner takes turns, and forerunner's wheel or pedal is avoided to injure child
Virgin foot, the foot of child feel more comfortable.
As shown in figure 23 and figure 24, child's tricycle forerunner wheel 1 is in double reduction mode.Specific operation process is such as
Under, user pulls the pull ring 81 for adjusting bracing wire 8, and driving 15 synchronous drive of screw rod driving fixture block 11 continues towards power teeth
The direction of disk 7A is slided, and compression spring 14 continues to squeeze, until the fixture block prominent 112 of driving fixture block 11 is embedded into power fluted disc
Between the fluted disc fan block 72A of 7A.Similar with primary speed-down mode, the revolving speed of driving assembly 9S is reduced, then, entire wheel body
As driving assembly 9S is travelled forward with lower speed.Although it should be noted that marking lid with the same label here
Body 2 and power fluted disc 7, still, by the reduction ratio difference for the deceleration system that lid 2 is formed with power fluted disc 7, to obtain difference
Deceleration mode.
As depicted in figs. 1 and 2, child's tricycle forerunner wheel 1 is on Full-Speed mode.Specific operation process is as follows, makes
Lid screw rod 3 is directly run through locking screw hole 251 and central siphon jack 103 by user, then, drive shaft tube 10 and lid 2 it is opposite
Position is locked, and when child's pushes pedals 42, entire driving assembly 9S directly drives lid 2 to be rotated, then, entire to take turns
Body is travelled forward with driving assembly 9S with identical speed.
It should be noted that adjusting bracing wire 8 in the guide card of drive shaft tube 10 during adjusting the traction of bracing wire 8
It is slided in mouth 102, so that the pulling for adjusting bracing wire 8 is more smooth.When adjusting bracing wire 8 is drawn on scheduled position, directly
It connects and the pull ring 81 for adjusting bracing wire 8 is anchored on the fixation skewed slot of corresponding fixed card column, for example the first fixed card column 43, second is solid
Determine card column 44 or the fixed card column 45 of third, respectively corresponds primary speed-down mode, the idle mode and two of child's tricycle forerunner wheel
Grade deceleration mode.
It is highly-safe since user can be suitble to the child of different age group with the ride mode of unrestricted choice tricycle.
Not limited to this, any change or replacement expected without creative work should all be covered in guarantor of the invention
Within the scope of shield.Therefore, protection scope of the present invention should be determined by the scope of protection defined in the claims.
