Abstract
The utility model relates to a driving mechanism for a quick steering tricycle, belonging to B62K class. The driving mechanism for a quick steering tricycle comprises a tricycle frame 10, a fly wheel 7, etc. The driving mechanism for a quick steering tricycle is characterized in that a pedal 2 and a big tooth disk 1 are fixed on the front end of the tricycle frame 10; the big tooth disk 1 is connected with a small tooth disk 4 on a rear additional shaft 5 by a chain 3; one end of the rear additional shaft 5 is also provided with a small tooth disk 4 ' and is connected with the fly wheel 7 on one end of a supporting shaft 8 by a chain 6; the shaft 5 and the shaft 8 are fixed on the tricycle frame 10; the other end of the shaft 8 is provided with a pair of gear fly wheels 9, 9' which are engaged; the gear fly wheel 9' is fixed on the other end of the rear additional shaft 5. When left and right wheels rotate, the utility model enables speed difference to exist, and the left and the right wheels can respectively steer using each side wheel as a circle center.
Description
The utility model relates to the B62K class, is applicable to the transmission device of manual tricycle.
The present manual tricycle, the particularly three-wheel vehicle of a front-wheel and two trailing wheels that uses, the follower of its back are to be driven by an axle to rotate, and are chain transmission modes; It turns to is to utilize the handlebar that is fixed on the front fork, the twisting front-wheel steering.When turning to, because be with the speed ratio transmission, do not have velocity contrast between the back two-wheeled like this, car body turns to shakiness, overturns easily, is difficult for handling.
The purpose of this utility model provides a kind of tricycle flexibly that turns to, and during turning, has velocity contrast between the trailing wheel, makes to turn to steadily.
This three-wheel vehicle transmission device comprises the transmission device that vehicle frame 10, flywheel 7, large toothed disk 1, chain 3, pedal 2 constitute, and it is characterized in that pedal 2, large toothed disk 1 are fixed on vehicle frame 10 front ends, and large toothed disk 1 coils 4 by chain 3 with the denticle on the additional shaft 5 of back and is connected; Back additional shaft 5 one ends that are fixed on the vehicle frame 10 also have denticle dish 4 ', are connected by the flywheel 7 of chain 6 with trailing wheel load-bearing axle 8 one ends; Load-bearing axle 8 is fixed on vehicle frame 10 rear ends, and the other end has a pair of gear flywheel 9,9 ', meshes between the two-wheeled, and flywheel gear 9 ' is fixed on back additional shaft 5 other ends.
The three-wheel vehicle transmission device of this new design is fixed on car front-wheel top with pedal, and body gravity is low, steady, safety.If additional shaft and gear flywheel make back shaft drive differential occur when turning, car body is turned flexibly, and not prone to tip over overcomes the deficiency that three-wheel vehicle is turned and easily fallen, can make the styling design of three-wheel vehicle be more suitable for the elderly and children, for example car body is littler, narrower, lighter.
Accompanying drawing 1 is this three-wheel vehicle drive mechanism birds-eye view:
Embodiment:
The three-wheel vehicle transmission device of this flexible rotation, comprise the transmission device that vehicle frame 10, flywheel 7, large toothed disk 1, chain 3, pedal 2 constitute, it is characterized in that pedal 2, large toothed disk 1 are fixed on vehicle frame 10 front ends, large toothed disk 1 coils 4 by chain 3 with the denticle on the additional shaft 5 of back and is connected; Back additional shaft 5 one ends that are fixed on the vehicle frame 10 also have denticle dish 4 ', are connected by the flywheel 7 of chain 6 with trailing wheel load-bearing axle 8 one ends; Load-bearing axle 8 is fixed on vehicle frame 10 rear ends, and the other end has a pair of gear flywheel 9,9 ', meshes between the two-wheeled, and flywheel gear 9 ' is fixed on back additional shaft 5 other ends.Gear flywheel 9,9 ' adds that by the freewheel body geared sleeve forms.Be meshing with each other between the geared sleeve.Brake 11 is selected band-type brake for use, is fixed on the front axle.
When pedal 2 rotates forward, by chain 3 drive denticle dish 4 on the additional shafts 5,4 ' and chain 6 and load-bearing axle 8 on together rotation forward of flywheel 7, drive right side wheels as driving wheel; Make the driven at the uniform velocity rotation of left side wheel and front-wheel.
When turning left, handlebar is turned round to left, the front-wheel deceleration of being obstructed; At this moment still continue Pedalling 2 the right-hand wheel revolution is increased, the revolution of left side flower wheel reduces relatively, and finishing with the left side wheel is the turning in the center of circle.
When bending to right, handlebar is turned round to right-hand, and the while is back-pedal pedal 2 backward, does not act on right wheel during flywheel 7 reversings, and denticle dish 4 ' drive axle 5 orders about flywheel 9 ' and turns round, and gear flywheel 9 changes forward, and driving left side wheel changes forward, and finishing with the right-hand wheel is the turning in the center of circle.Can also be on the user crown suitable height frame rain shade, become the windproof box car that keeps off the rain.
Move to normal handlebar position, human body front as pedal, when more existing handlebar being moved to vehicle frame left side or right side by connecting rod, just develop into the car for disabled persons of with the hands handling walking and turning with front end.
