Specific implementation mode
As shown in Figure 1, it includes front fork 1, handle 2, headstock 3, front-wheel 4, saddle 6, folder to pedal that this trailing wheel is disposable
Gu pad 7,9, two trailing wheel connecting rods 5 of wing nut and two trailing wheels 8.Handle 2 is fixed on the upper end of front fork 1, before front-wheel 4 is mounted on
The lower end of fork 1.As shown in figures 7 and 9, the montant 36 of front fork is passed through from the center of headstock 3, and 37 in Fig. 7 are to hold in headstock
Receive the groove of montant 36, montant 36 can be rotated relative to headstock 3 to make front-wheel deflect, and control the direction of advance of car.Such as figure
6, shown in Fig. 7, Fig. 8, fixed two pieces of link blocks 31 in headstock 3, this two pieces of link blocks 31 are located at the both sides of the montant 36 of front fork,
Link block 31 is clamping firmly by the protecgulum 34 and rear cover 35 of headstock.As shown in Figure 6 and Figure 8, have in the middle part of every piece of link block one to
The connecting shaft 32 that the back lower place is stretched out, there is a circle flange 33 at the middle part of this connecting shaft 32.As shown in Figure 2, Figure 3 and Figure 4, every trailing wheel
The center of the front end 52 of connecting rod 5 it is axial there are one and 32 matched connecting shaft hole 54 of connecting shaft, connecting shaft hole 54 it is interior
There is a circle groove 55 in the middle part of wall.As shown in figure 9, the front end of trailing wheel connecting rod 5 is linked in connecting shaft 32, the flange 33 in connecting shaft
It is entrenched in the groove 55 of the inner wall of connecting shaft hole 54, makes that trailing wheel connecting rod and connecting shaft are combined securely and trailing wheel connects
Bar can make 360 degree of rotations relative to connecting shaft again.As shown in figure 11, two trailing wheel connecting rods 5 are parallel to each other；As shown in Fig. 2, trailing wheel
Respectively there are two assemble shrinkage pool 53 for the upper and lower surface at the middle part of connecting rod 5.As shown in Figure 10, there are two rows in the lower surface of saddle 6
Totally four assembly convex blocks 61 (often arrange two), the center of the lower surface of saddle 6 have one to downwardly extending bolt 62, clamping pad 7
There are one bolts hole 71 at center, and respectively there are the fin 72 of one piece of upward bending in the both sides of clamping pad 7.As shown in figure 11, the four of saddle 6
In the assembly shrinkage pool 53 for the upper surface that a assembly convex block 61 is respectively inserted in two trailing wheel connecting rods 5, the bolt 62 of saddle 6 is inserted in two
Between trailing wheel connecting rod 5, clamping pad 7 is sleeved on by bolt hole 71 on the bolt 62 of saddle 6, two pieces of fins 72 fitting of clamping pad 7
On the lower surface of two trailing wheel connecting rods 5, trailing wheel connecting rod is encased, wing nut 9 is screwed in the lower end of the bolt 62 of saddle 6,
7, two trailing wheel connecting rods 5 of clamping pad and saddle 6 are fastened, state shown in Fig. 1 or Figure 12 is become.As shown in figure 3, every
The rear end of trailing wheel connecting rod 5 has one to the hind axle 56 extended laterally, and trailing wheel 8 is linked in the end of hind axle 56, and 57 are in figure
The cover of hind axle 56.The conversion of tricycle and two wheeler need to only screw off wing nut 9, remove saddle 6 and clamping pad 7, by two
Root trailing wheel connecting rod respectively rotates 180 degree, then saddle 6, clamping pad 7 and wing nut 9 are reinstalled, and is very convenient.Rotation two
Root trailing wheel connecting rod makes two trailing wheels be in inside, as soon as shown in Figure 1, two trailing wheels are leaned on together into a wheel, car
As two wheel constructions.Two trailing wheel connecting rods of rotation make two trailing wheels be in outside at as shown in figure 12, become two trailing wheels, vehicle
Son just becomes tricycle structure.The combination of the upper assembly shrinkage pool 53 of four assembly convex blocks 61 and two trailing wheel connecting rods 5 on saddle 6
There are two the effects of structure, when the position of fixed saddle well, second is that the postrotational positioning of trailing wheel connecting rod is fixed.
