Abstract

The invention relates to a motorized one-wheeled wheelbarrow on which a combustion motor b has been fitted to facilitate the propulsion. In order also to facilitate start-up and transport on downhill slopes and lock the wheel during loading and dumping, a power transmission system has been devised in which the integral machine elements are constituted by a centrifugal coupling, a continuously adjustable belt gear d, governed by the speed of the motor, a cardan rod and a worm gear a. <IMAGE>

1. 7904333-7 2 bli frirullande överförs drivkraften till skottkärrans drivhjul via en snäckväxel (a). Detta arrangemang gör att skottkärrans drivhjul låses när motorn går på tomgång eller står stilla vilket är lämpligt vid tippning och lastning. Vidare finns i kraftöver- föringssystemet en automatisk steglöst reglerbar remväxel (d) vars utväxlingsförhållande styrs av motorns varvtal på så sätt att när motorvarvet sjunker ökar utväxlingsförhållandet. Remväxeln strävar alltså efter att hålla motorvarvet konstant vilket medför att utväxlingen ökar i uppförsbackar och minskar i utförsbaokar. Kraftöverföríngen från remväxeln till snäckväxeln sker med kardan- stång. Motorn placeras mellan kärrans stödben vilket ger låg tyngdpunkt_och god balans och vidare skyddas motorn för âverkan. Lämpliga typer och storlekar på ingående komponenter: Kärra utförd med rörram och plåtlåda. 3 kW bensinmotor med membranförgasare okänslig för lutning. Centrifugalkoppling. ' Steglös remväxel. Snäckväxel utväxling 60:1. Kullagrat luftgummihjul diameter 250 mm.i Gasreglage utfört som rullhandtag (motorcyke1tyP) eller liten spak (gräsklippartYP). Patentkrav Enhjulig skottkärra utrustad med förbränningsmotor (b), ett mellan motorn och kärrhjulet anordnat kraftöverföringssystem, vilket system innefattar en oentrifugalkoppling, en automatisk steglöst reglerbar remväxel (d), styrd av motorns varvtal, samt en kardan- axel, k ä n n e t e c k n a d a v att i kraftöverföringssystemet tingår en snäckväxel (a) mellan kardanaxeln och kärrnjulets axel,1. 7904333-7 2 become free-rolling, the driving force is transmitted to the wheel of the wheelbarrow via a worm gear (a). This arrangement means that the wheelbarrow's drive wheels are locked when the engine is idling or stationary, which is suitable for tipping and loading. Furthermore, the power transmission system has an automatic steplessly adjustable belt gear (d) whose gear ratio is controlled by the engine speed in such a way that when the engine speed decreases, the gear ratio increases. The belt gearbox thus strives to keep the engine speed constant, which means that the gear ratio increases on uphill slopes and decreases on downhill slopes. The power transmission from the belt gear to the worm gear takes place with a universal joint. The engine is placed between the support legs of the cart, which gives a low center of gravity_ and good balance, and furthermore the engine is protected from impact. Suitable types and sizes of components: Trolley made with tubular frame and metal box. 3 kW petrol engine with diaphragm carburetor insensitive to inclination. Centrifugal coupling. 'Stepless belt pulley. Worm gear ratio 60: 1. Ball-bearing pneumatic rubber wheel diameter 250 mm. A unicycle wheelbarrow equipped with an internal combustion engine (b), a power transmission system arranged between the engine and the wheelwheel, which system comprises a non-centrifugal clutch, an automatically steplessly adjustable belt gear (d), controlled by the engine speed, and a propeller shaft. there is a worm gear (a) between the propeller shaft and the core Christmas shaft,
