The vertical front-wheel below Vehicular turn bar is on the same line, will exist in which one when car turns to
Individual wheel cannot contact unbalanced problem with ground, therefore will design and installation one put down on vehicle frame 42
Weighing apparatus device be used for solving after vehicle two-wheel when turning to double rear wheel face balance problem contiguously (as Fig. 8, Fig. 9,
Shown in Figure 10 and Figure 11), thus solve do not have one of them wheel when Vehicular turn cannot be with
The problem of ground contact, wheel fork just can play two-wheeled direction, left and right alignment and balance and exercise.
As shown in Figure 8, Figure 9, Figure 10 and Figure 11, the two-wheel wheel fork of described a kind of band vibration damping, it is special
Levy and be: bascule is mainly made up of balance cross arm 34, spring pedestal 29 and spring 30, in balance
The middle upper part of cross-arm 34 is provided with the connection lug 31 of a band axis hole 38, at balance cross arm 34 two ends
Be respectively equipped with a spring pedestal mounting groove 39 on platform, below spring pedestal 29 for be provided with one with
The engaging lug 36 of pin shaft hole 35, spring pedestal 29 be arranged over one for pacifying spring-loaded boss 41,
Bearing pin 32 is by the pin shaft hole 40 on the spring pedestal mounting groove 39 of balance cross arm 34 and spring pedestal 29
Spring pedestal 29 is arranged on the spring pedestal of balance cross arm 34 by the pin shaft hole 35 on the engaging lug 36 of lower section
On mounting groove 39, connecting shaft 33 is by the axis hole 38 connecting lug 31 in balance cross arm 34 and crane span structure
Bascule and dual wheels wheel fork are movably connected on rear wheel frame 42 by the connecting shaft hole 1 on 2.
The two-wheel wheel fork of described a kind of band vibration damping, it is characterised in that: wheel shaft 12 back end design becomes fixed block
23, the installing hole 22 communicated with the lower screw hole 27 of prismatic axle 14 is arranged on fixed block 23.
The operation principle of the two-wheel wheel fork of a kind of band vibration damping of the present utility model is: when vehicle is in the middle of exercising
When road is uneven on road, owing to being provided with crane span structure 2 between two wheel forks, and crane span structure the right and left sets
Put and be cased with shock-absorbing spring on the prismatic guide pin bushing 13 in wheel fork linking arm 6 installing hole and the right and left wheel fork 8
Prismatic axle 14 is flexibly connected, and therefore when in the middle of exercising, road is uneven vehicle, prismatic axle 14 can
Move linearly up and down along with the vibration of spring 15 is done in the prismatic axle movable span 17 of prismatic guide pin bushing 13, from
And play vibration damping and shock-absorbing effect.Design due to the structure of prismatic axle 14 again, change a piece wheel shaft horizontal stroke of tradition
Connect two sidecar wheels design, the design of prismatic axle 14 can not only play two-wheeled direction, left and right location and
The enforcement of balance, and can reach again the purpose of independent shock-absorbing, due to crane span structure 2 and wheel fork 8 band vibration damping
The wheel fork on design both sides can play the function of gravity balance along with the inclination of vehicle when turning.
