Abstract

A stub axle double rear wheel drive manpower tricycle relating to a manpower tricycle aims to solve the problem that slide inertia shortage of existing tricycle makes rider very tired. Two ends of a left dead axle (5) are respectively fixed on a vehicle frame left outer beam (19) and a vehicle frame left inner beam (20); both ends of a right dead axle (6) are respectively fixed on a vehicle frame right inner beam (21) and a vehicle frame right outer beam (22); a left vehicle wheel (15) is positioned on the left dead axle (5) and a left flywheel (8) is fixed on the left vehicle wheel (15); a right vehicle wheel (16) is positioned on the right dead axle (6) and a right flywheel (9) is fixed on the right vehicle wheel (16). The utility model has the advantages that: with double rear wheels adopting stub axles, the utility model generates slide inertia, making rider comfortable; due to stub axle double rear wheel drive, drive shaft firstly drives the rear wheel at one side moving slower during riding, thereby increasing riding safety factor during running forward or turning off and saving physical strength for rider.

Description

The minor axis double rear wheel drives manual tricycle

Technical field

The utility model relates to a kind of manual tricycle.

Background technology

Two wheels of existing manual tricycle back are generally all only by a major axis and a chain drive, and only body moves an one-sided wheel, and the wheel of opposite side is a flower wheel.Like this like the people in go-cart forward, if the people pushes away forward in the side of three-wheel vehicle, although also can use power, the multipotency of the efficient of exerting oneself is used on the car about 70%, if push away in the back of car, the usefulness that the efficient of exerting oneself almost can 100% onboard.Because such three-wheel vehicle can not drive two trailing wheels simultaneously by bike the time, if drive two trailing wheels simultaneously, three-wheel vehicle can not be turned.And since two rear wheels on same transmission shaft, two-wheeled produces resistance mutually, the bad or overload when road conditions, axletree and yielding, distortion back is because two wheels can not parallelly advance, resistance increases more.Though the three-wheel vehicle that adopts two chains to drive two trailing wheels has respectively been arranged at present, but because two rear axles are long, only quite that an axle is therefrom separated, load onto bearing respectively at open circuited position then, its shortcoming is: because two axles are all long, both waste materials can increase the weight of car again; The inner of two axles needs in the middle part of car body bearing to be installed, complex structure so not only, be not easy to install and maintenance, and axletree or spindle nose are also yielding, the shortcoming of common three-wheel vehicle does not change, and the same with general major axis three-wheel vehicle, does not slide and is used to power, one step was not pedaled, and car will soon stop.

The utility model content

The purpose of this utility model is to lack to slide and be used to power, the problem that cyclist's sensation is tired especially for solving existing three-wheel vehicle.Provide a kind of minor axis double rear wheel to drive manual tricycle.The utlity model has characteristics simple in structure, that car body is in light weight, it is laborsaving to ride, safety factor is high.The utility model is made up of main gear chain 1, left driving chain 2, right driving chain 3, main driving axle 4, left fixed shaft 5, right fixed shaft 6, driving chain wheel 7, left flywheel 8, right flywheel 9, Left Drive sprocket wheel 10, right driving chain wheel 11, sprocket for main drive 12, clutch shaft bearing assembly 13, second bearing assembly 14, left wheel 15, right wheel 16, vehicle frame inner beam 17, the vehicle frame back rest 18, vehicle frame left outer beam 19, vehicle frame left inner beam 20, vehicle frame right inner beam 21, vehicle frame right outer beam 22, the front beam of frame 23; The vehicle frame back rest 18, vehicle frame left outer beam 19, vehicle frame right outer beam 22 and the front beam of frame 23 rectangular being fixed together, the two ends of vehicle frame inner beam 17 are separately fixed at the front portion between vehicle frame left outer beam 19 and vehicle frame right outer beam 22 inboards, vehicle frame left inner beam 20 and vehicle frame right inner beam 21 are fixed between the vehicle frame inner beam 17 and the vehicle frame back rest 18 in parallel to each other, main driving axle 4 is fixed between the front beam of frame 23 and the vehicle frame inner beam 17 by the clutch shaft bearing assembly 13 and second bearing assembly 14, driving chain wheel 7 is fixed on the middle part on the main driving axle 4, be provided with main gear chain 1 between sprocket for main drive 12 and the driving chain wheel 7, Left Drive sprocket wheel 10 and right driving chain wheel 11 are separately fixed on the two ends, the left and right sides of main driving axle 4, the two ends of left fixed shaft 5 are separately fixed on vehicle frame left outer beam 19 and the vehicle frame left inner beam 20, the two ends of right fixed shaft 6 are separately fixed on vehicle frame right inner beam 21 and the vehicle frame right outer beam 22, left wheel 15 is arranged on the left fixed shaft 5, left side flywheel 8 is fixed on the left wheel 15, right wheel 16 is arranged on the right fixed shaft 6, right flywheel 9 is fixed on the right wheel 16, be provided with left driving chain 2 between left side flywheel 8 and the Left Drive sprocket wheel 10, be provided with right driving chain 3 between right flywheel 9 and the right driving chain wheel 11.The beneficial effects of the utility model are: since double rear wheel of the present utility model all usefulness be minor axis, be used to power so slide when riding, make the cyclist feel brisk especially.Drive because the utility model is the minor axis double rear wheel, which side trailing wheel loses time painstakingly when walking, and transmission shaft just at first drives the trailing wheel of which side, so car when moving ahead or turn, has increased the safety factor of driving, has saved cyclist's muscle power.
