Description

A kind of bicycle

The utility model relates to a kind of gear-driven bicycle, belongs to the unpowered vehicle class.

Existing all kinds of bicycles, as mountain bike, ordinary bicycle, its transmission is chain gear, thereby has shortcomings such as driving efficiency is lower, this vehicle body height in addition, Gu center of gravity is also high, be difficult for grasping steadily to begining to learn, when turning and Uneven road, the rider is easy to fall down, handlebar is in bicycle the place ahead, and rider's both arms are supporting above the waist, and arm is easy to fatigue.

The purpose of this utility model provides a kind of labour-saving bicycle, and that this bicycle has is easy and simple to handle, laborsaving, the characteristics such as comfortable of riding.

The purpose of this utility model is to realize like this.This car comprises: handlebar (1), front-wheel (5), trailing wheel (3) is characterized in that the axis (7) of front-wheel (5) is provided with driving wheel (9), front fork (6) is provided with flower wheel (8) is set on power wheel (10) front-wheel (5), driving wheel (9), power wheel (10), flower wheel (8), be meshing with each other, the handlebar of Armrest shape (1) is arranged on the trailing wheel (3), is positioned at the both sides of the seat (2) of band backrest, and front-wheel (5) diameter is greater than trailing wheel (3).

Be further described below in conjunction with embodiment the utility model.

Fig. 1 is the front view of the structural representation of the utility model embodiment.

Fig. 2 is the back view of Fig. 1.

Fig. 3 is the front-wheel of Fig. 1 and the partial schematic diagram of transmission device.

Among Fig. 1,2, the handlebar of 1 Armrest shape, the seat of 2 band backrests, 3 trailing wheels, 4 back vents, 5 front-wheels, 6 front forks.

Among Fig. 3,5 front-wheels, 6 front forks, 7 axis, 8 flower wheels, 9 driving wheels, 10 power wheels, 11 pedals.

This bassinet structure adopts front-wheel (5) to drive, and is fixed on the driving wheel (9) on the axis (7), steps on pedal (11), axis (7) and driving wheel (9) promptly rotate, driving wheel (9) drives power wheel (10), and power wheel (8) drives flower wheel (10), drives front-wheel (5) and advances.The rider partly lies on the seat (2) of band backrest, handles the handlebar (1) of the Armrest of seat (2) both sides, adjusts direction of traffic.

This car adopts gear drive to drive front-wheel, the whole accent of rear wheel rotation driving side To, handlebar is located at two of band back of chairs, and in addition, the vehicle body center of gravity is low, because of And this car the has advantage such as laborsaving, easy and simple to handle, safe, comfortable.
