Go Kart Drive Line elements can be rather costly, particularly if you are considering making your very own trusted inexpensive go kart. Common expenses for drive line elements can be in the series of 100 to 200 dollars. The inexpensive option, nevertheless, to the standard chain-clutch driven system is the belt drive.

The standard belt drive includes a motorist on the engine and an owned on the drive wheel or axle. The belt is tensioned either by moving the engine forward or by pressing a belt tensioner on the belt.

There are a number of crucial requirements for a belt drive. The correct ratio and 2nd the correct type elements.

Go Kart Belt Drive Ratio

The belt drive system in order for it to work needs a high ratio of 8:1. Any less of the engine and a ratio will stall and the go kart will need pressing in order for it to go. (This 8:1 ratio presumes the wheel is 12 inches in size.) The general rule for the pulley-block size is that the owned pulley-block has to be as big as the tire. Any smaller sized and the ratio will be insufficient and the engine will stall or the belt will smoke.

Proper Component Selection

One of the huge errors that very first time go kart home builders will make is to utilize a sheave that is constructed out of zinc. Generally these wheels can be discovered at hardware shops; nevertheless, they are unable to deal with the horse power requirements of go karts. If you do utilize a sheave that is made out of aluminum or zinc the pulley-block will melt after about 10 minutes of usage. The pulley have to be constructed out of steel.

The next crucial style requirements about an engine pulley-block is that is has to be as little as possible. A size of 1.75 has to do with at big as you can precede the ratio ends up being out of variety and the engine stalls and smokes belts.

Additionally, the pulley-block will get piping hot and has to be kept in location with Loctite and a bolt on completion of the engine to avoid it from coming off of the engine. And clearly the pulley-block has to be keyed to the engine to guarantee correct torque transmission to the pulley-belt.

The driven side of the go kart is a totally various matter. The pulley-block can be made from sandwiched plywood as the low expense homemade option or the pulley-block can be purchased a regional tractor supply shop. Since it is really inexpensive and can be installed straight to a wheel by means of bolts, the wood pulley-block is appealing.

The belt tensioner system needs some resilient tensioner wheels. Those too can be acquired at a regional hardware shop. The belt tensioner is essentially a sheave that is jammed into the face of the belt triggering the belt clearance in between the engine motorist and the wheel sheave to decrease. This now tensioned belt grabs better and triggers the wheels to turn.

It is necessary to be on the slack side of the belt when utilizing a tensioner; otherwise you will be battling the engine and continuously burning up belts. The method to take a look at a belt is to see it as a glorified elastic band. The belt extends as it passes the engine pulley-block.

The stress side will constantly be tight, however the tensioner on the slack side motivates complete belt wrap; which is the crucial to the belt drive: a minimum of 180 degrees or more of belt twist around the engine pulley-block.

The concept is to obtain as much area getting the belt so that it effectively moves load through and to the rest of the drive system.

The tensioner system can be triggered by a lever arm or a cable television. When the clutch is unlatched the engine is not spinning the tires, typically a spring is utilized to shut down the system so that.

Important Note About Belt Tensioners

This is a crucial note about belt clutch systems. When no human input is being done, constantly make the system shut down by itself. The foot launches the pedal, the clutch instantly launches. The factor for this is if the engine is being begun, the last thing you desire is for it to be in equipment. This will trigger the go kart to stumble forward throughout launch. Once again, it is necessary to have the clutch system shut down instantly.
