Description

Tricycle

One, technical field

The utility model relates to a kind of manpower transportation, and particularly a kind of vehicle body is similar to the Kickboard Scooter size, can stand and step on capable Tricycle.

Two, background technology

Existing bicycle is too big, is not easy to carry, and Kickboard Scooter only is to have the function that amusement is played, I am at the Chinese patent ZL01246029.x " bicycle " of application on June 19 calendar year 2001, though bicycle and Kickboard Scooter function are combined as a whole, its structure is complicated, and cost is higher.I apply for that Chinese patent ZL0124627.3 and Chinese patent ZL02215042.0 have introduced " the planetary concentric sleeve speed increaser of pinwheel " and " the planetary concentric sleeve speed increaser of gear ", but these two kinds of patents are mainly used in the speedup of bicycle.

Three, summary of the invention

The utility model technical issues that need to address are: simplify driver train, make its structure more reasonable, be convenient to batch manufacturing.The technical solution of the utility model is: Tricycle, comprise vehicle frame, the direction seat that connects vehicle frame and steering handle, steering wheel is fixed on the front fork of direction barre, the rear portion of vehicle frame is fixed with power wheel, planetary concentric sleeve speed increaser, flywheel, chain and step, the direction seat is folding, by the folding button clamping of the direction seat of vehicle frame below, it is characterized in that: two power wheels are fixed on the two ends of planetary concentric sleeve output shaft of the speed increaser, fix two flywheels by the silk tooth on the planetary concentric sleeve speed increaser input shaft, near on the vehicle frame of two flywheels an end being installed is the step of T-shaped skeleton for the pedal other end, respectively be with one section chain at two flywheels, one end of chain is fixed on the step T-shaped skeleton, the other end is fixed in the extension spring of bottom of frame, two step isoplanars be arranged in parallel, and planetary concentric sleeve speed increaser can adopt one-level speed increasing mechanism or multi-stage acceleration mechanism.If perambulator type Tricycle, planetary concentric sleeve speed increaser can adopt the one-level speed increasing mechanism, can be a kind of in " the planetary concentric sleeve speed increaser of pinwheel " and " the planetary concentric sleeve speed increaser of gear ".If adult type Tricycle, planetary concentric sleeve speed increaser can adopt multi-stage acceleration mechanism, with the secondary speedup is example, the pipe, satellite gear, fixed gear, shaft gear, output shaft, bearing, the little bearing that comprise shell, cover plate of outer casing, band disk, the gear that it is characterized in that cover tape splicing disk between satellite gear and output shaft, symmetry is equipped with two or four rotating secondary planet wheels on the gear of band disk, respectively with secondary fixed gear that is fixed on outer casing inner wall and the shaft gear clamping that is socketed in output shaft.The beneficial effects of the utility model are: because at the fixing planetary concentric sleeve speed increaser of the afterbody of Tricycle, two power wheels are directly installed on the output shaft of planetary concentric sleeve speed increaser, by step, chain and flywheel as imput power, make Tricycle can reach the moving velocity the same with bicycle, and the amusement and the portable function that have possessed Kickboard Scooter again, simple in structure, be convenient to implement.

Four, description of drawings Fig. 1 is that the utility model structural representation Fig. 2 is in the utility model secondary speedup planetary concentric sleeve speed increaser cross section structure scheme drawing figure for the planetary concentric sleeve speed increaser cross section structure scheme drawing Fig. 5 of the utility model for the planetary concentric sleeve speed increaser master TV structure scheme drawing Fig. 6 of the utility model for the utility model pedal power structural representation Fig. 4 for the utility model folding effect figure Fig. 3: the 1-vehicle frame, 2-direction seat, the 3-steering handle, the 4-steering wheel, the planetary concentric sleeve speed increaser of 5-, the 5a-shell, the 5b-cover plate of outer casing, the pipe of 5c-band disk, 5d-satellite gear, the 5e-fixed gear, the 5f-shaft gear, 5g-output shaft, 5h-bearing, the little bearing of 5i-, the gear of 5j-band disk, 5e1-secondary fixed gear, 5d1-secondary planet wheel, the 6-flywheel, the 7-step, the 8-power wheel, 9-folds button, the 10-chain, the 11-extension spring.

Five, specific embodiment embodiment 1: with reference to Fig. 1,3,4,5, Tricycle, comprise vehicle frame 1, direction seat 2, steering handle 3, steering wheel 4, planetary concentric sleeve speed increaser 5, flywheel 6, step 7, power wheel 8, folding button 9, chain 10, extension spring 11, planetary concentric sleeve speed increaser 5 adopts the one-level speed increasing mechanism, comprise shell 5a, cover plate of outer casing 5b, the pipe 5c of band disk, satellite gear 5d, fixed gear 5e, shaft gear 5f, output shaft 5g, bearing 5h, little bearing 5i, there is planetary concentric sleeve speed increaser 5 at the rear portion that is fixed on vehicle frame 1, flywheel 6, step 7, chain 10, extension spring 11, bearing 5h is arranged in the shell 1, be installed with a band disk pipe 5c in the bearing 5h, but an end of pipe strand has the silk tooth of stationary bicycle flywheel, symmetry is equipped with two rotating planetary wheel 5d on the disk of pipe, the fixed gear 5e that is fixed on shell 1 inwall is arranged in the outer end of planetary wheel 4, two ends at band disk pipe 5c respectively are embedded with a little bearing 5i, be installed with an output shaft 5g among the two little bearing 5i, pipe is stretched out at the two ends of output shaft 5g, and all be furnished with cotter way and Si Ya, be used for fixing Tricycle power wheel 8, also fix a shaft gear 5f on the output shaft 5g, the cover plate of outer casing 5b of the little bearing 5i of edge in the middle of Feng Youyi on the shell 1.Two flywheels 6 are fixed on the pipe 5c of band disk, and left and right sides step 7 is installed in respectively near on the vehicle frame 1 of flywheel, and end points is fixed with chain 10 and band on two flywheels 6, and chain 10 has and returns an extension spring 11.Direction seat 2 is folding, by folding button 9 clampings of the direction seat of vehicle frame below.When stepping on when riding this car, only bipod need be depressed in the step of the left and right sides in turn and lift, since about two steps 7 respectively by chain 10 pulling two flywheels 6, thereby the up-and-down movement of step 7 must make two flywheels do to come and go rotation, and flywheel has clockwise input, reverse the function of backlash, therefore two flywheels 6 are constantly done to come and go to rotate, the input shaft band disk pipe 5c of planetary concentric sleeve speed increaser 5 is only turned in the same direction, speedup through several times makes output shaft 5g, reach rotating speed faster, thereby make power wheel 8 twirl, determined the moving velocity of Tricycle thus.With reference to Fig. 2, in the time will packing up Tricycle, can pull folding button 9, direction seat 2 is collapsed to the slide type vehicle frame together with steering handle 3, otherwise open as the same.

Embodiment 2: with reference to Fig. 1,3,5,6, when adopting the planetary concentric sleeve speed increaser of secondary speedup, comprise shell 5a, cover plate of outer casing 5b, the pipe 5c of band disk, satellite gear 5d, fixed gear 5e, shaft gear 5f, output shaft 5g, bearing 5h, little bearing 5i, the gear 5j of band disk, secondary planet wheel 5d1, secondary fixed gear 5e1, the gear 5j of cover tape splicing disk between satellite gear 5d and output shaft 5g, the symmetry that goes up the gear 5j of band disk is equipped with two rotating secondary planet wheel 5d1, respectively with secondary fixed gear 5e1 that is fixed on shell 5a inwall and the shaft gear 5f clamping that is socketed in output shaft 5g.The pipe 5c of band disk rotates, satellite gear 5d also rotates, be subjected to stopping of fixed gear 5e, make satellite gear 5d reverse, and rotation passed to the gear 5j that is with disk that the gear 5j of band disk can rotate, and transmission passed to secondary planet wheel 5d1, the rotation of secondary planet wheel 5d1 is subjected to stopping of secondary fixed gear 5e1 again and reverses, and rotation is passed to shaft gear 5f, and has made output shaft 5g speedup more than ten times.All the other are identical with embodiment 1.
