Abstract

The utility model relates to a multifunctional tricycle adopting a direction control wheel disk to control directions, which is provided with a speed changing transmission chain, an advancing-backing operating mechanism, a backrest elastic chair and a movable double seat, so that the gear can be changed, the speed can be adjusted, the multifunctional tricycle can turn flexibly and can advance and back, and the maneuvering performance is good. The utility model has the advantages of labour saving and shapely configuration. The design of the appearance is semi-streamline-shaped, and the multifunctional tricycle is passenger-cargo dual-purpose means of transportation, which is suitable for countrysides and towns.

Description

Multifunctional tricycle

The utility model is a kind of town and country short distance traffic instruments.

At present, with the tricycle that the vehicle use, only be mostly the vehicle as short distance as the special purpose of carrying or loading.Adopt single grade, can only advance and can not retreat, operator's saddle is the Triangulum orange, and direction control realizes by directly rotating handlebar.Its shortcoming is comparatively to require great effort when riding, particularly go up a slope or situation that road conditions are bad under particularly outstanding, thereby people's susceptible is tired, maneuvering performance is relatively poor, not much for many years improvement.The purpose of this utility model be to provide a kind of energy shifted, can forward-reverse, flexibly controlling party to, and design has the backrest driver seat and for two self folding seats that the passenger uses, it is laborsaving to ride, the mixed-traffic multi-functional tricycle that maneuvering performance is good.

Accompanying drawing 1 is the complete vehicle structure scheme drawing.The top of direction actuating spindle (2) is equipped with one can drive the direction control panel (1) that axle rotates, the middle part is installed with direction tie-plate (3), the rotation direction control panel drives the direction tie-plate (5) be fixed on the front fork by shackle line (4) and rotates, reach controlling party to purpose.Front car light (6), dynamic loud-speaker (7), 20 English inch front-wheels (8), front brake (9), (10) are high back elasticity driver seats.Adopt this seat can make the people utilize the support power at back, comfortable being sitting in naturally pedaled row on the arm-chair.Forward-reverse control handle (11), back brake control handle (12), front brake control handle (13), pedal (14), 36 toothed chain wheels (15), chain (16), 20 tooth flywheels (17), 36 tooth flywheels (18), rear axle (19), 26 English inch wheels (20), (21) be the folding self folding seat that hinges is housed between backrest and seat orange, during carrying seat is inserted in the hole fixing on the railway carriage, can take off during loading, fold up to insert in the anterior fixing hole of railway carriage and make front baffle board, (22) are hoods.

Accompanying drawing 2 is speed change messenger chain scheme drawings.Car is to overtake the time, and when sprocket wheel (15) left-hand revolution is people when stepping on pedal forward, chain (16) drives 20 tooth flywheels and rotates, and this moment, car was with the 1.8:1 fast running; When the sprocket wheel clickwise is that the people steps on pedal when counter-rotating, the idle running of 20 tooth flywheels drives 36 tooth flywheels by third wheel (23) and rotates, and this moment, car travelled at a slow speed with 1:1.This shows that car is when advancing, the sense of motion that the people only need change pedal can reach the purpose of speed change.Sprocket wheel (15) is identical with common three-wheel vehicle with the mounting structure of pedal, and 20 tooth flywheels and 36 tooth flywheels all adopt ordinary bicycle or three-wheel flywheel in vehicle.

Accompanying drawing 3 is forward-reverse steering unit scheme drawings.Handle forward-reverse handle (11), two the pin disks (25), (28) that shift fork (24) are stirred be installed on the rear axle (19) change travel direction.In the left side of 20 tooth flywheels and the right side of 36 tooth flywheels pin-and-hole disk (26), (27) that fixedly become one with rear axle are housed respectively.Two flywheels and rear axle are bearing fit and design has pin-and-hole, has only in pin on the pin disk inserts the hole of pin-and-hole disk and in the hole of flywheel the time, just can make flywheel drive rear axle and rotate.When shift fork moves right, when the pin on the pin disk (25) inserts on pin-and-hole disk (26) and the 20 tooth flywheels pin-and-hole simultaneously, car is with the speed of 1.8:1 or 1:1 to overtake, when shift fork moves to left, when making pin on the pin disk insert on pin-and-hole disk (27) and the 36 tooth flywheels pin-and-hole, when stepping on pedal forward and being the sprocket wheel left-hand revolution, car just retreats, otherwise car marches forward at a slow speed with the speed of 1:1.It when shift fork is in the middle part neutral gear.

The car load appearance design is a semi-streamlined form, and decorative colour can design with people's hobby, and whole appearance design better appearance is generous.

In sum, the utility model has the province of stepping on power than old-fashioned tricycle of past because can be shifted, go up a slope and situation that road conditions are relatively poor under can select for use at a slow speed.Design has the forward-reverse steering unit and utilizes bearing circle control rotation direction, easy to use, turn flexibly, make this car have manoevreability preferably, the most parts of car load adopt standard parts and components simultaneously, be designed to assembly type, demolition, installation, transportation, easy to maintenance are suitable for doing cities and towns, rural passenger and freight transportation vehicle.
