CN102815166A - Drive technique for front-wheel driven bicycle - Google Patents

Abstract

The front-wheel driven bicycle is technically characterized by transmission without chains, turning directions by a rear wheel, short wheel base, light weight, easy riding and labor saving. A implementation method is as follows: a passive gear, a driven gear and a second passive gear are driven by the rotation of a crank, a shaft and a drive gear, the second passive gear is connected with the housing of a flywheel; the teeth of the flywheel housing are engaged with a active iron in the flywheel under the effect of a spring to dive the wheel to rotate, so the wheel still rotates due to inertia when the crank stops. The square aperture of the crank coincides with the square end of the shaft, and the internal aperture of the square end of the shaft has wires, components on the shaft are tightly fixed on a frame by screws, and the tightness is regulated by crews and a washer.

Description

The actuation techniques of Frontwheel driven bicycle

Technical field:

F-w-d rotates with one group of wheel driving gear without chain, must be equipped with " bicycle prone position tricycle is separate the technology that turns to front fork ", could realize rear-axle steering.

Technical background:

Front drive vehicle is can design-calculated small-sized, almost can with wheelbarrow shoulder to shoulder, and multiple functional, also can sitting crouches is having very comfortable riding on the car of the chair back, saving in material, cost is low, the gross vehicle weight amount is light, it is brisk, laborsaving to ride.

The physical structure principle is following:

Comprise: crank, driving gear, ring gear, driven gear, flywheel, the iron of living, bearing, axle skin, two ends square toes axletree.

Description of drawings:

Fig. 1 is total figure, and Fig. 2 is the flywheel scheme drawing, and Fig. 3 is a schematic perspective view.

Among the figure 1, driving gear, 2, ring gear, 3, driven gear, 4, bearing, 5, flywheel, 6, the axletree skin, 7, crank, 8, vehicle frame, 9, the square toes axletree, 10, the iron of living.

Driving gear 1 is fixed together with crank 7 and is positioned on the square head shaft 9; Rotating crank 7 just drives ring gear 2 together with driving gear 1 and rotates with driven gear 3; The 2nd ring gear 2 connects together with flywheel 5; Iron alive 10 on the tooth of flywheel 5 and the axletree skin 6 is meshing under the effect of spring, and just drive wheels is rotated; Crank 7 stops, wheel inertia rotation still.

Crank hole is square style, matches with the square toes of axletree 9, and not outer silk on the axletree 9, square two ends endoporus has silk, and it has two effects: 1. with sieve staple crank 7.2. the fastening and parts of assembling on the axletree 9 are on vehicle frame 8.Elasticity is regulated by Luo Ding and packing ring.

Common axletree is fixed on the vehicle frame, and this axletree 9 rotates with crank 7 together.

This money car is not established speed change, and speed ratio is fixed, and driving gear 1, driven gear 3 are bigger than ring gear 2, are fixed up after twice speed change.
