[embodiment]
Be further described below in conjunction with accompanying drawing.
Referring to accompanying drawing, creep into (1) encircle greatly front-wheel stride the seat (1 8) on (2) crescent moon saddle the seat saddle on, step (1 9) stretcher, (9) driving gear that (8) crank is attached thereto is paid driving gear with (10) and is rotated simultaneously, drive (1) and encircle (24) internally toothed annulus of front-wheel inboard greatly, advance by (5) trailing wheel on its drive (2) tooth saddle rear portion (15) after poppet seat and (6) trailing wheel on the support, in the process of advancing, can pull (12) that are installed in (17) front frame seat on (2) crescent moon saddle, turn to handgrip to make (12) turn to (13) pile extension on the handgrip that (5) rear wheel support is swung as turning to.(6) back crop rotation on the drive support swings to reach and turns to the order point, for making (2) crescent moon saddle stable riding over (1) encircle on the front-wheel greatly, 2 groups of (7) caterpillar wheels are housed on the certain position of (2) crescent moon saddle, and encircle in the front-wheel then the edge in its edge and (1) greatly and be equipped with four groups and be stuck in (4) regulating tank, (3) righting wheel specially rises and sets upright, (2) effect of crescent moon saddle does not break away from the two being attached to together tightly, plays safe dynamic role.Drive (1) and encircle (9) driving gear of front-wheel greatly, in establish unidirectional (11) ratchet, when (1) was encircled front-wheel greatly and rolled forward fast, (8) crank can not rotate, (9) driving gear becomes ring gear.This moment, unidirectional (11) ratchet was made slip/stick movement, and the inertia that reliable (1) encircles front-wheel greatly continues to roll forward, and player does not need to step yet and can advance this moment.(20) brake is controlling by the bonded assembly braking rope; Be contained in (21) brake on two rear drums, can regulate the speed at any time.(10) paying that driving gear is connected with (9) driving gear is by the two tangent transmissions of taking turns between waist of gear are installed, for Large round wheel and major-minor driving gear are skidded, the spy makes five millimeters at every interval on large pulley inner arc drum muscle top, open one five mm wide, the little tooth of one millimeters deep, to increase friction coefficient, make it to become (a 24) bull gear, combine well for making with (24) bull gear, at major-minor driving gear and caterpillar wheel, the righting wheel outer ring all adopts rubber mass to make, so also can lower the noise that friction produces, the manufacturing technology of this toy car concerning this professional people still clearly.
