Abstract

A lever bicycle comprises a flywheel, gears, a center shaft, cranks, pedals, pressure bars, ball bowls, balls, ball baffles, an outer wheel, chains, chain wheels, chain wheels with spikes, bearings, semi-annular fixing plates, a rear shaft, a spring sub wheel, a locking spike and circumferential pressure cranks. The lever bicycle is technically characterized in that the pedals on the left side and the right side of the center shaft are connected with the cranks, and the pedals are connected with the pressure bars through the ball bowls, the balls and the ball baffles; the circumferential pressure cranks are integrated with the bearings and are connected with the chain wheels with the spikes through bearing internal threads; the spike heads of the chain wheels with the spikes are connected and fixed through the pressure bars; the chain wheels and the bearings are welded into a whole; the bearing internal threads are connected with rear shaft threads; the chain wheels and the chain wheels with the spikes are connected through the chains; the gears and the rear shaft are connected in a threaded mode; the semi-annular fixing plates, a bicycle frame and the chain wheels are fixed into a whole; the locking spike is welded to the left semi-annular fixing plate; the gears and the bearings are fixed on the locking spike; the gears and the flywheel are fixed on a central round pipe of the spring sub wheel which is connected with the outer wheel through a spring. One bearing is arranged in the central round pipe of the spring sub wheel and connected with the rear shaft. Labor and time are saved, and speed is high.

Description

Lever bicycle

Technical field:

The present invention relates to bicycle, three-wheel vehicle, particularly lever bicycle.

Background technology:

The ordinary bicycle speed of a motor vehicle is slow, and physical demands is large, relies on manpower to improve speed of a motor vehicle limited extent.Although shift bicycle has multi-gear transmission, laborsaving when the object of speed change mainly makes people scrunch, and it is undesirable to increase substantially speed of a motor vehicle effect, and shift careless manipulation, also easily take off chain.Known speeding-up bike speed is faster, and when people is scrunched, physical demands is more required great effort more greatly.

Summary of the invention:

It is low that object of the present invention is intended to solve existing bicycle speed, and physical demands is large, and shift speedup effect is undesirable, and provide one not change bicycle structure, scrunch mode, when making to ride, the speed of a motor vehicle is very fast, physical demands is little, the lever bicycle under leveraged pressure effect.

The technical scheme realizing foregoing invention object is: this lever bicycle comprise axis, cripple, stretcher, pressure thick stick, pearl bowl, ball, pearl gear, outer wheel, chain, sprocket wheel, band nail sprocket wheel, bearing, the solid plate of semi-circular, gear, flywheel, rear axle, bar accessory whorl, dead nail, week pressure the parts composition such as to turn.Be threaded with cripple at axis Vehicular left pedal, Vehicular left pedal has pearl bowl, ball, pearl gear is connected with pressure thick stick, with all press to turn to weld tie on bearing, pressure turned bearing negative thread with being with and followed closely sprocket wheel and nail on and be threaded week, band nail sprocket wheel ailhead has pressure thick stick to be connected and fixed, and band nail sprocket wheel and pressure thick stick are integrated.Connect with rear axle left end pin, sprocket wheel is welded on bearing, bearing negative thread is threaded with rear axle, sprocket wheel follows closely sprocket wheel with band has chain to connect, gear is threaded with rear axle, the solid plate of semi-circular and vehicle frame weld and became one, the solid plate of semi-circular has bolt to be connected with sprocket wheel, dead tack welding knot is on the solid plate of semi-circular, gear weldering knot is on bearing, bearing is fixed on and extremely nails on, together with gear and flywheel weld and tie, flywheel is connected with bar accessory whorl center pipe outside thread, bar accessory whorl square section is the separate component of king's word shape, bar accessory whorl outer ring has clockwork spring to be connected with outer wheel, bearing is had to be connected with rear axle in the pipe of bar accessory whorl center.Be threaded with cripple in axis right steps, right steps has pearl bowl, ball, pearl gear is connected with pressure thick stick, press in week and turn weldering knot on bearing, pressure turned bearing negative thread with being with and followed closely sprocket wheel and nail on and be threaded week, band nail sprocket wheel ailhead has pressure thick stick to be connected and fixed, band nail sprocket wheel and press rods are integrated, week press to turn and be connected with rear axle right-hand member pin, sprocket wheel weldering knot is on bearing, bearing negative thread is threaded with rear axle, sprocket wheel follows closely sprocket wheel with band has chain to connect, and the solid plate of semi-circular and vehicle frame weld and became one, and the solid plate of semi-circular has bolt to be connected with sprocket wheel.

According to the lever bicycle described in this case, have good effect at bicycle art, be characterized in that pedal band kinetic pressure is shouldered, pressure shoulder to press with week turn together with rotate, week pressure turn and do circular-rotation, pressure is shouldered and is turned rotation with week pressure and play elongation and contraction.In torque one timing, leverage is played in cripple's growth.Compared with known bicycle, there is speedup successful, drive laborsaving, simple and compact for structure, the advantage of low cost of manufacture.
