Abstract

The utility model provides a walking type bicycle. The utility model is a new bicycle aiming at overcomes the deficiencies of the uncomfortable riding, relative labor pedaling and unsafe get on and off etc. A three-wheel structure is used for the bicycle, and two rear wheels have small spacing and both are driving wheels. The utility model adopts a set of pedal driving device, and changes the arc reciprocated movement of the pedal to the transmission mechanism of continuous rotary of the rear wheel. The riding of the bicycle like the marking time and the utility model has relaxed and comfortable driving, and smooth and safe driving. Due to the bicycle body is small and flexible in maneuvering, and easy to carry and store. The bicycle can be used as a popular traveling bicycle.

Description

The stepping type bicycle

Affiliated technical field

The utility model relates to a kind of bicycle, a kind of pedal-actuated tricycle.

Background technology

China is " bikedom ", also is the manufacturing basis of world's bicycle.But standard bicycle be subjected to fast development automobile, battery-driven car serious impact and face atrophy, some reasons are huge by the car body that himself exists, center of gravity is too high, drives that defective such as effort causes.Modern society be badly in need of a kind of drive comfortable, take deposit conveniently, the portable bicycle of maneuverability, take a bus instead of walking to satisfy people, lie fallow travel, the demand of body building.

Summary of the invention

For overcoming some deficiency of standard bicycle, the utility model carries out the essence transformation to the body construction and the driver train of bicycle, and driving is light, car body is small and exquisite to reach, the purpose of driving safety.

The utility model for the technical scheme that the technical solution problem adopts is: adopt tricycle structure, stand-type driving, two trailing wheel spacings are little and be all free wheel, hinged two Active foot plates of fixed pedestal on the vehicle frame, two Active foot plates connect chain respectively, chain pile warp sprocket wheel is mounted on the flywheel on two rear wheel hubs respectively, retracing spring of each suit on the wheel shaft on two flywheels next door.One end of two retracing springs connects flywheel teeth, and the other end connects vehicle frame.The handlebar lower end is two montants, is installed on two sleeves liftable.Vehicle frame is single crossbeam, and its rear end is connected with hind axle between two trailing wheels.Can install vehicle seat additional on the vehicle seat column on the vehicle frame.

The beneficial effects of the utility model are: 1, adopt the parallel structure of double rear wheel, and both basic the adaptation at a high speed, more adapt to low speed, can not get off during parking.(2) adopt pedal drive, the legs and feet movable amplitude is little, and car body is reduced greatly, and center of gravity reduces greatly; Because the health drive is big, and the drive angle is little, so drive both strong, laborsaving again.(3) sprocket wheel had both moved chain and had been controlled, and play the effect of amplifying transmitting ratio again, and the flywheel crank motion was converted into the movement in a curve of pedal the revolution of trailing wheel effectively.Realize automatically reseting of flywheel, chain, pedal by spring, this driving device not only simply but also reliable.In sum, it is easily comfortable to the utlity model has driving, drives steady safety, distinguishing features such as car body small volume and less weight, and do not learn just can, so this car is expected to become a kind of popular bicycle of riding instead of walk.

Description of drawings:

Fig. 1 is an embodiment constructional drawing front view; Fig. 2 drives scheme drawing;

Fig. 3 is that embodiment constructs birds-eye view;

Among the figure: 1, front-wheel, 2, trailing wheel, 3, fixed pedestal, 4, Active foot plate, 5, connecting rod, 6, chain, 7, sprocket wheel, 8, flywheel, 9, hind axle, 10, retracing spring, 11, vehicle frame, 12, front fork, 13, steering bearing sleeve, 14, handlebar, 15, the two montants of handlebar, 16, two sleeves, 17, the vehicle seat column, 18, vehicle seat.

The specific embodiment:

In the drawings, front-wheel (1) is installed on the front fork (12), and trailing wheel (2) is installed on the hind axle (9).Handlebar (14) is two montants (15), and two montants (15) are inserted on two sleeves (16), are fixed by screw.Vehicle frame (11) front end connects steering bearing sleeve (13), and its rear end connects hind axle (9) between two trailing wheels.Fixed pedestal (3) is equipped with in vehicle frame (11) below, and fixed pedestal (3) connects Active foot plate (4) by bearing, and connecting rod (5) is arranged on the Active foot plate (4), and connecting rod (5) connects chain (6), and chain (6) connects flywheel (8) through sprocket wheel (7) back.Sprocket wheel (7) is installed on the vehicle frame (11), and flywheel (8) is installed on the inboard wheel hub of trailing wheel (2), and spring (10) is sleeved on the hind axle (9).Vehicle seat (18) is positioned on the vehicle seat column (17).

The driving procedure of this car is: the people stands on the car, and the pin front portion is stepped on fixed pedestal (3), has lifted up the pin rear portion and has stepped Active foot plate (4) up and down, affects chain (7), and flywheel (8) moves reciprocatingly, and flywheel (8) drives trailing wheel (2) and drives to move ahead.
