THE BIKE IN THE TRUNK

Before you engage in the construction of microvesicle, I’ve been drawing various versions of its layout, trying on paper for all possible errors and miscalculations, which can only occur in the process. Looking ahead, it should be noted that designing on paper is one thing, fabrication is another. Many of the “roughness” out in the operation of the machine.

 

Initially, the majority of the items I thought to do it myself, because I dreamed about microvesicle not resemble any of the published pages of technical journals. But when he so lovingly painted mud flaps, fuel tank, saddle embodied in metal, leatherette, and foam, compared with drawn, they have lost all its appeal. Reluctantly had to use commercially available parts. But as it turned out, it was good for my car — it has become quite acceptable.

 

As for the performance of the bike and its reliability, I’m quite satisfied with them, as about” has traveled about 3000 km without any breakdowns. The only drawback (but it’s not my fault!) — weak samokatnaya tires. For the front wheel wherever you went, and for the rear… Have to wear on the rim from two pieces, but it is not very helpful.

The maximum speed of microvesicle up to 50 km/h, it is well “holds” the road and is quite stable. Dimensions allow you to freely place it in the trunk of a “Moskvich”. The weight of microvesicle is so small that it can be entered on the fifth floor (no Elevator!) and deploy virtually anywhere in the apartment.

Now about the design of the machine. The configuration of the frame (Fig. 2). determined the use of engine D-6. For her pipe Ø 28 mm and Ø 14 mm borrowed from old bike frames. The rear pendular suspension welded from tubes Ø 21 mm Front fork from a moped “Riga”. Only had to shorten: cut the feathers and the stem 130 mm, and the feathers on the bottom welded bracket (Fig. 5). Front wheel from scooter with no alterations, it fit speedometer reducer. The wheel a motorcycle “Java”. It placed the Gaza strip, clutch lever, standard lever drum brake rear wheel, switches, lights and audio signal.

Headlight, gas tank, seat, alarm, rear shocks and muffler — standard, from the moped “Verhovina”. Mud flaps from the same moped — I took one back and cut it in half. The pipe connecting the engine with the muffler, pipe, bent in place. Stand motorcycle eight-millimeter welded from steel rod and pivotally attached to the frame.

One of the most complex parts of microvesicle — rear wheel. It had to be carved from duralumin, because it bears the main burden. Hub and rim are made at the same time, inside the first are two bearings. The driven sprocket (Z=28) is welded to the steel flange. The brake drum is on the right.
