Description

The health tourism three-wheel vehicle

The utility model relates to a kind of old-aged training, tricycle for traveling of riding usefulness for two people simultaneously.

The old three-wheel vehicle that has now formed commodity all is that a people is pedaled in front, and another people sits in the back.When having ridden for a long time or having gone up a slope, the outrunner is with a face streaming with sweatly tired, and the people of back but energetically makes nowhere, is a burden purely, expects that place tourism nature slightly a little further is just forbidding.From the angle of body-building, also can only make cyclist's lower limb obtain taking exercise.

Though Patent Office of the People's Republic of China disclosed the utility model patent of a kind of " body-building traffic three-wheel vehicle " on June 1st, 1994 in CN2167026Y number bulletin, this car can be taken two people, the people of back seat can participate in driving by the rowing machine of operation steel cable transmission, but this " body-building rowing machine " only pulls back just and can work, and efficient is lower.

The purpose of this utility model is to be people, and providing a kind of in particular for old man and wife can together play, the health tourism car that again can muck in makes upper limbs and lower limb obtain taking exercise.

In order to achieve the above object, the utility model structurally has following feature (see figure 1):

Car load by sufficient drive system 1, hand-drive system 2, back seat 3, child's seat 4, child's handrail 37, baggage container 5, tool box 6, and parts such as supporting with it vehicle body 7, handle 8, front and back wheel 9, illuminating lamp 10, light deflector 11, Cornering Lamp 12, stoplight stop lamp 13, front and back braking 14 form.

The structure of foot drive system is identical with existing three-wheel vehicle, all is to drive hind axle 29 by crank, chain drum, chain, flywheel to rotate, thereby car is advanced.

Hand-drive system (see figure 2) is made up of hand-drive axle 15, finishing

bevel gear cuter

16,17,18,19, left overriding clutch 20, right overriding clutch 21, rocking bar 22 (about each 1), bearing seat 23 (about each 1), chain drum 24, chain 25, flywheel 26, spacing ring 27 (about each 1), reverse clutch 28.

When driving handle 22 forward, power is by axle 15, left overriding clutch 20, drive the clockwise direction rotation together of chain drum 24 and finishing bevel gear cuter 16, and drive hind axles 29 by chain 25, flywheel 26 car is advanced, when finishing bevel gear cuter 16 drive chain drums 24 were done the clockwise direction rotation, because the commutation effect of finishing bevel gear cuter 17,19, finishing bevel gear cuter 18 was made anticlockwise direction and is rotated, because awl tooth 18 connects firmly with right overriding clutch 19, so can only dally on axle 15; When pulling back handle 22, power makes an awl tooth 18 and an anticlockwise direction rotation together by axle 15 right overriding clutchs 21, and through 17,19 commutations of awl tooth, 16 of finishing bevel gear cuters drive chain drum 24 and still keep previous clockwise direction rotation.This moment, the switched in opposite of finishing bevel gear cuter 16 and axle 15 was promptly oppositely swayed, but drive hind axle 29 by chain 25 and flywheel 26 in the same old way car is advanced because left overriding clutch 20 effects are arranged.

This three-wheel vehicle also has stays sloping function automatically.If unable continuation drives, this car can be parked on the slope automatically when going up a slope, and the slope of can not backing off is gone, for the elderly has increased safety control by bike.

When needing reversing, pinching clutch handle 39 (see figure 3)s separate dental clutch left part 34 and right part 31 by shift fork 33, and this moment, flywheel 26 can dally on axle 29, and car just can fall back.Release handle 39, under the promotion of spring 35, dental clutch the right and left meshes again, and flywheel 26 can be passed to hind axle 29 to power by dental clutch and dive key 32 again, and car is advanced.

The corollary equipment of three-wheel vehicle will be further described in an embodiment therewith.

Description of drawings:

Fig. 1 is front elevation of the present utility model and birds-eye view;

Fig. 2 is a diagram of gears;

Fig. 3 is the reverse clutch constructional drawing.

In conjunction with the embodiments the utility model is further described again below:

The utility model has former and later two adult seats as can be seen from Figure 1, but front and back two people can drive also independent drive simultaneously.The outrunner uses sufficient drive system, and rides common three-wheel vehicle and is as good as.The human hand-drive system of back can both drive car by push-and-pull campaign before and after the left and right sides handle work and advance.Both interesting, can take exercises again, also can alleviate conpanion's physical load.The former tempers lower limb, and the latter tempers upper limbs and back.Just can reach the purpose of upper and lower limb all round exercise by the front and back position exchange.

Between former and later two adult seats, also be provided with baby seat 4 and handrail 37 thereof, be convenient to the grandparents and be with little grandson to swim altogether, increase family happiness.
