Description
The present invention relates to a kind of two sitting posture multipurpose three-wheel bike that drives, contain wheel, car vertical tube of front fork, connecting rod, bearing circle, vehicle frame bend pipe, floral disc wheel, chain, vehicle seat, flywheel group, braking mechanism and back axle.
In the daily life, the transport facility that people used always has bicycle and three-wheel vehicle, their type of drive is the single driving of striding type, and vehicle supporting gravity height, poor stability, can not reach the purpose of most riding and loadings, and because three-wheel vehicle is inclined to one side three-wheel, the same with bicycle, sharply turning or easily fall down when meeting accident accident causes major accident.
Therefore, a kind of " seat type tricyle " disclosed in Chinese patent 85107493, be to pedal with mode to change a formula into by striding type, the support unit of promptly pedaling personnel selection is one to have the seat of backrest, the pedal assembly is positioned at the front portion of vehicle frame, and to make its force angle be 90 °-140 °, handlebar changes preceding handle into, preceding wheel diameter is less than the back wheel diameter, this design can change the unreasonable state of the heavy support pattern of striding type three-wheel disjunctor, drives though this structure changes striding type into sitting posture, still is single effort that drives when manned, and be that inclined to one side three-wheel supports, stability is still relatively poor.
The objective of the invention is provides a kind of Complex multiplication that realizes to use and reduce two sitting posture multipurpose three-wheel bikes that drive of the center of gravity of operator's support, good stability, variable-ratio for fear of above-mentioned the deficiencies in the prior art part.
The objective of the invention is to realize by following measure:
A kind of two sitting posture multipurpose three-wheel bike that drives, contain wheel, the car vertical tube of front fork, connecting rod, bearing circle, the vehicle frame bend pipe, the floral disc wheel, chain, vehicle seat, the flywheel group, braking mechanism and back axle, tricycle is that three-wheel supports to equicrural triangle, vehicle frame is by a left side, right vehicle frame bend pipe and middle bend pipe are welded on the car vertical tube of front fork and form, corner at left vehicle frame bend pipe is equipped with bearing circle, bearing circle crank connecting link car vertical tube of front fork, on a left side, respectively there is a floral disc wheel right vehicle frame bend pipe both sides, two flywheel groups are arranged on back axle, between floral disc wheel and flywheel group variable gear is housed, chain connects floral disc wheel and flywheel group hinge wheel respectively, variable gear, flywheel group minor sprocket has guiding stay bearing plate and spring guiding mechanism on back axle, on the guiding stay bearing plate, be associated with the vehicle frame strut bar, and link with the vehicle frame bend pipe, on the vehicle frame bend pipe, be placed with vehicle seat, on middle vehicle frame bend pipe and back axle, braking mechanism is housed.
Purpose of the present invention can also realize by following measure:
The end that the floral disc wheel of two driving sitting posture multipurpose three-wheel bikes is gone up chain links to each other with flywheel group hinge wheel, and chain is walked around hinge wheel and linked to each other with variable gear, and chain is walked around variable gear and linked to each other with minor sprocket, and the chain on chain is walked around minor sprocket and floral disc is taken turns links to each other; Braking mechanism on the central frame beam bend pipe can brake with brake handle, also available brake step brake; The vehicle seat of tricycle is that two row's backrest seats are movably arranged on the vehicle frame bend pipe, and rotatable 180 ° of back seat forms the compartment, and the chair back can be put to level attitude.
The present invention has following advantage compared to existing technology:
1, striding type is changed into a formula, the operator supports the employing chair, alleviated the operator labour intensity, laborsaving;
2, vehicle body is low, and good stability is difficult for when fast running or sharply turning overturning;
3, adopt two the driving, realized Complex multiplication usefulness, but and loading;
4, adopt wheel steering, slewing area is little, driving safety;
5, because vehicle seat is two row seats, be fit to family tourism usefulness, pick that old man or patient go out and the upper and lower use of child etc.

The present invention also incites somebody to action in conjunction with the accompanying drawings, and 1,2 embodiment are described in further detail:
With reference to Fig. 1,2 wheels (1), optional available from the criterion of train running wheel, wheel is mounted to equilateral triangle, vehicle frame is by a left side, right and middle vehicle frame bend pipe (5) is welded on the car vertical tube of front fork (2) and forms, bend pipe is a thin-wall steel tube, corner at left vehicle frame bend pipe (5) is welded with the bearing circle standpipe, bearing circle (4) can be selected gauge member for use, bearing circle (4) links to each other with car vertical tube of front fork (2) by connecting rod (3), left side at vehicle frame, right bend pipe (5) both sides respectively is equipped with a floral disc wheel (6) and step, equal selection standard spare, on back axle, be coaxially installed with two groups of flywheel groups (11,12), and in floral whorl dish (6) and flywheel group (11,12) deflection is equipped with a variable gear (16) between, one end of chain (8) is walked around floral disc wheel (6) and flywheel group (11,12) hinge wheel (11) links to each other, chain (8) is walked around hinge wheel (11) and is linked to each other with variable gear (16), chain (8) is walked around variable gear (16) again and is linked to each other with the minor sprocket (12) of flywheel group, chain (8) is walked around minor sprocket (12) and is linked to each other with the last chain (8) of floral disc wheel (6), can change the speed of a motor vehicle by just stepping on counter stepping on, when anti-card punching plate wheel (6) conter clockwise turns round when running into upward slope, the hinge wheel of flywheel group (11) clockwise rotates, thereby drive variable gear (16) anticlockwise motion, make the minor sprocket (12) of flywheel group rotate counterclockwise, so transmission speed ratio is that floral disc wheel (6) has been realized decelerated movement with the ratio of number of teeth of minor sprocket (12); On middle vehicle frame bend pipe and back axle braking mechanism is installed, braking mechanism can be used brake handle (7) brake, also available brake step (17) brake; And the spring guiding mechanism is installed and the stay bearing plate (13) that leads on back axle, vehicle frame strut bar (10) and guiding stay bearing plate (13) welding, the spring guiding mechanism is made up of four pilot bars (14) and eight cylindrical springs (15), and eight springs (15) are formed four groups of spring bearings by two different spring housings of diameter respectively together, guiding stay bearing plate (13) is fixedly connected with an end of pilot bar (14), the other end flexibly connects and is spacing with nut, in the middle of two guiding stay bearing plates (13), support with spring (15), can play buffer action, minimizing is jolted; And vehicle frame strut bar (10) and vehicle frame bend pipe (5) welding are placed with vehicle seat (9) on vehicle frame bend pipe (5), and vehicle seat (9) is two row's backrest seats, and seat is to form with electroplating soft chair installation, and the fluffy formula parasols of weather can be installed thereon; Rotatable 180 ° of back seat forms the compartment, and the chair back also can be put into level attitude, is used for the roping long load.The present invention be applicable to pick the old man or patient goes out, the upper and lower class of upper and lower of children, man and wife, Holiday family tourism and roping goods, be a kind of multiduty transport facility.
