CN2163136Y - Man-power vehicle booster - Google Patents

Abstract

The utility model provides a novel man-power vehicle booster which is integrated with the functions of clutch, transmission, speed reduction, starting, and braking. The utility model is mainly composed of a driver, and a controller. The driver adopts two stage speed reduction, the first stage is planet speed reduction, and the second stage is gear speed reduction. The inner gear of the planet speed reducer is arranged on the big bearing of the driver, three bearings are arranged in the driver, a driving shaft is supported by the two small bearings, and the inner gear is supported by the big bearing. The small gear of a gear speed reducer is connected with the planet gear of the planet speed reducer, and the big gear of the gear speed reducer is directly connected with the wheel drum of the back wheel of a bicycle. The controller is provided with a forward direction knee brake and a backward direction knee brake, and the controller is composed of a rocking rod and an eccentric wheel. The utility model has the advantages of reliable controller operation, light weight, small volume, free and convenient running, and wide application range.

Description

Man-power vehicle booster

What the utility model provided is that a kind of employing miniature gasoline engine is as power, through double reduction, through the rickshaw walk helper of multi-functional driver direct drive trailing wheel.

Domestic have a front-wheel friction, trailing wheel friction, trailing wheel belt, chain, gear (cylinder or circle pincers gear) transmission.The wheel (Japan, France, Britain etc.) that abroad rubs, gear type (Germany, Denmark, Belgium, Holland etc.).Wheeled transmission is simple though rub, and driving efficiency is low, wheel and ground and wheel arranged and the double rub of the wheel that rubs, the aggravation wear on tyres, and the air pressure to wheel has higher requirements simultaneously.Gear, though the chain gear machinery driving efficiency is higher, complex structure, cost increases.The indispensable centrifugal throwing piece (automatic centrifugal clutch) of wherein full car, the operation power-transfer clutch, starting surmounts and starting device retarder, the overriding clutch etc. of riding.

The purpose of this utility model is to overcome the defective of above-mentioned existence, proposes a kind of novel bicycle walk helper that collects clutch, transmission, deceleration, starting, braking five functional one.

Technical solution of the present utility model: rickshaw (bicycle, three-wheel vehicle) walk helper is by spark ignition engine, driver, and controller is formed.Spark ignition engine adopts single-cylinder air-cooled spark ignition engine, the COI igniting.Driver adopts double reduction, and the first order is a planetary reduction gear, and wherein inner gear 9 usefulness bearing supports are loose commentaries on classics state in the enclosure, and the second stage is gear reduction 6, and wherein miniature gears is contained on the pinion carrier 7, and big gear wheel links to each other with the drive wheel wheel hub.Controller is by rocking bar 20, eccentric shaft 19 and belt rifle lock 8 are formed, the rocking bar lower end is fixed on the eccentric shaft on the transmission shell, belt rifle lock two ends are contained on the eccentric shaft up and down, the rocking bar upper end links to each other with the handlebar manipulating wire, carry out forward and reverse braking (starting is subjected to force direction antithesis with motor-driven) of the internal top circle of belt rifle lock, thus transmission, deceleration, clutch, starting, idling and the braking of control the utility model patent (utilizing the engine off braking).

Accompanying drawing is a structural representation of the present utility model.

Among the figure 1 is big chain cover, the 2nd, and chain, the 3rd, flywheel, the 4th, little chain guard, the 5th, trailing wheel (drive wheel), the 6th, second stage gear reduction, the 7th, first order planetary reduction gear pinion carrier, the 8th, belt rifle lock, the 9th, inner gear, the 10th, reed air inlet, the 11st, the filtering carburetter, the 12nd, crank (flywheel), the 13rd, noise silencer, the 14th, permanent magnetism, generating and trigger winding, the 15th, the silicon control high voltage package, the 16th, cylinder, piston, connecting rod, the 17th, light-up plug, the 18th, radiating gill, the 19th, eccentric shaft, the 20th, rocking bar, the 21st, bearing designation, the 22nd, oil sealing sign.

The utility model adopts the bi-directional braking special construction, and because of starting is subjected to force direction antithesis with motor-driven, this structure makes the controller reliable operation.As long distance brakings of need (following big slope) or interim reduction of speed, can adopt the flame-out driving engine that makes to help braking (this moment, throttle should be threaded to minimum, with saving fuel).Great advantage is to adopt the existing bicycle in home and abroad, but new car dispatch from the factory (containing walk helper), but also used car repacking (user voluntarily or manufacturer help repacking), so have bigger survivability.Be applicable to kiddie car fully, speed of a motor vehicle 16Km/n, load-carrying 250Kg.

Claims (1)

1, rickshaw walk helper, form by spark ignition engine, driver, controller, spark ignition engine adopts single-cylinder air-cooled spark ignition engine, the COI igniting, it is characterized in that adopting the first order is planetary reduction gear, the second stage is the driver of gear reduction, inner gear 9 usefulness bearing supports in its first order planetary reduction gear in the enclosure, be loose commentaries on classics state, the miniature gears in the gear reducer of the second stage is contained on the first order planetary reduction gear pinion carrier 7, and big gear wheel links to each other with the drive wheel wheel hub; Controller is a rocking bar 20, and eccentric shaft 19 and belt rifle lock 8 formed, and the rocking bar lower end is fixed on the eccentric shaft on the transmission shell, upper and lower being contained on the eccentric shaft in belt rifle lock two ends, and the rocking bar upper end links to each other with the handlebar manipulating wire.
