SCOOTER UNDER THE ROOF | MODEL CONSTRUCTION

Does not make sense to compare a scooter-a scooter and a car — these cars are totally different. However, the designers of motorcycles continuously attempt to give the two-wheeled vehicle in comfort of their four-wheeled counterparts. In recent years, increasingly on the streets of cities, there are lightweight scooters-scooters equipped with a fairing resembling devoid of doors the body of the passenger micro-car, only. This combined transport is not an example of comfortable traditional bike — especially for our country with its climate, abundant spontaneous precipitation “in the form of rain and wet snow.”

We present the design of the scooter is developed on the basis of the parts of a moped “Karpaty” and motorcycle “Minsk” the engineer I. Dnevnikom. His structure is an elongated and squat mokik, it is suitable to equip it with a nice fairing.

Probably not much point in a detailed story about the vehicle — such diys in the “Modeller-designer” told more than once. Let us mention only its main design features.

The frame of the scooter — spinal type, bent steel tube 34×2,5 mm. Front fork of the motorcycle “Minsk”, is only slightly shortened. The wheel — a home-made, bent tubular steel 22×1,5 mm. Back of the pendulum fork handmade (in principle, might be applied with standard bike . or motorcycle “Minsk”), amortizat-‘ ry — from “Minsk”. Fuel tank from a moped “Riga-11”. If a tank is harder to manage (“Riga-11” is no longer available), I suggest to use a suitable plastic canister from-under engine oil — you only need to install it on a standard motor crane is a cesspool.

The layout of the scooter:

1 — front wheel (from a moped “Karpaty”); 2 — front mudguard (Karpaty); 3 — front fork (from a motorcycle “Minsk”, modified); 4 — headlight (Minsk); 5 — bracket lights (aluminum strip 50×5); 6 — wheel (steel, pipe 22×1,5); 7 — frame; 8 — engine V-50 (Karpaty); 9— seat; 10 — back; 11—nacelle; 12 — fuel tank (from a moped “Riga-11” or plastic tank); 13 — rear shock absorber (“Minsk”, 2); 14 — tail light (Karpaty); 15 — rear mud flap (Karpaty); 16 — rear wheel (Karpaty); 17 — back of the pendulum fork; 18 — Bush roller chain 19 — silencer (Karpaty)

Engine — type V-50 (these were installed at the time almost all domestic mopeds), with foot lever-switch gear box and foot-starting lever-kick starter.

Seat and back — homemade, same design. Both consists of a plywood (12 mm thick) base, cushions of cellular rubber (two layers of 20 mm), foam (one or two layers at 40 mm) and a covering of artificial leather. Mount backrest and seat to the frame using the brackets, bent from steel sheet of thickness 2 mm. Drive front brake— standard, manual, using rope in budenovskoy shell, rear — foot, homemade foot pedals mounted on the frame of a scooter with the right hand; with brake device of the rear-wheel pedal connects also cable budenovskoy shell

The frame of the scooter Assembly with front n rear forks (dimensions with an asterisk to clarify the place):

1 — front fork (from a motorcycle “Minsk”, modified); 2 — frame reinforcement (steel, sheet s2, 2); 3 — front mounting bracket engine (steel, sheet s3); 4 — spinal beam frame (steel tube 34×2,5); 5 — strengthening the rear mount of the engine (steel, sheet s2,2); 6 — bracket for seat mounting (steel, channel 50x25x2,5, L100,2); 7 — rear shock absorber (Minsk, 2); 8 — lever tor-* brake device (steel, sheet s3); 9 — bushing the brake device (steel, pipe 16×2); 10 — the lever of a brake pedal (push rod from a child’s Bicycle); 11 — Klondike (steel, sheet s3. 2); 12 — plate (steel strip 40×3, 2); 13 — axle hinge pin rear fork (steel,

шпилькаМ12 with nuts and washers); 14 — bottom mount rear shock (steel, bolt M10, 2); 15 — mounting bracket of the rear wheels (steel strip 40×3,2); 16 — beam rear fork (steel, pipe 24×2,5,2); 17 — the base of the rear mount of the engine (steel, pipe 34×34); 18 — rear bracket engine mounts (steel, sheet s3. 2); 19 — verhnii the attachment point of the backrest (steel, sheet s2); 20 — cross member (steel, steel 30×2,5); 21 — upper bracket rear shock absorber (steel, M10, 2 PCs.); 22 — Klondike (steel, sheet s2,5, 2); 23 — bracket (steel, sheet s3. 2): 24 — bushing (bronze or nylon, 2 pieces); 25 — cross member (steel, strip 40×5); 26 — the case of the rear hinge plug (steel, pipe 36×2,5). In the types G and D absorbers are conventionally not shown

The deflector is lightweight and consists of a plywood frame, foam filler and a shell of fiberglass and epoxy resin.

The basis of the frame are two frames stitched together from 6 mm plywood. Wikiepedia each of the two layers so that the joints overlap; total thickness of each frame, therefore, will be 12 mm. Prepared frames combined in the frame of the fairing with the cross members cut from 12 mm plywood. Joining of crossbars with the frames — in the spike. At the bottom of the frame are joined using a couple of steel studs and the M12 nuts with washers. Openings in the frontal and rear Windows are glued edging out of 6 mm plywood — these will be attached to the glazing of 4 mm plexiglass.

Fairing of the scooter:

1 — crossbar (plywood si2); 2 — filling (construction foam); 3,5 — glazing (plexiglass s4); 4 — trim the window opening (plywood s6), 6 — frame fairing (two layers of plywood s6); 7 — ties (M12 stud with nuts and washers)

The finished frame is checked for absence of distortions and asymmetry, after which the front, rear and roof parts are filled with bars construction foam it is glued by using epoxy binder. After the adhesive has cured, the excess foam is cut with a long razor-sharp knife, and then the surface brought to the required forms coarse sandpaper, glued to a plywood plate. Foam wedges are also on the side surface frames and rounded, which gives the fairing a completely finished look. This is followed by coating of fairing fiberglass (from two to five layers depending on thickness) using as a binder an epoxy resin.

Thus prepared fairing vyshkurivaetsya, if necessary, is aligned with autosplice, newly polished with sandpaper and painted with enamel. Preferably in two colors: dark bottom and bright top. The inside cone is painted in gray color.

In the finished fairing fixed glass, after which he installed on the scooter.

Control of the scooter, equipped with a fairing, is no different from managing a conventional moped.
