The swinging carriage is also tubular, welded. The front roller leading and the driving sprocket and brake disc are fixed on the front shaft of the carriage, which, in turn, pipe welding rotator: it is on two bearings 203. The drive sprocket is fixed with four bolts and nuts on the hub, and that, in turn, is fixed on the shaft with a pair of plug lap joint (so-called the connection of the two parts formed in the Cup holes in one of them). The axis of rear rollers rear motorcycle recalls — it can also be moved along the elongated grooves at the ends of the side members of the carriage for adjusting the tension of the belt.
The layout of a snowmobile:
1 — the exhaust pipe of the engine; 2—engine TG-200M (working volume 199 cm3, power 14 HP); 3 —fuel valve-settling tank; 4 — steering column; 5 — fuel tank (aluminum canister with a capacity of 10 liters); 6 — wheel; 7 — frame (steel pipe and 40×2 30×2,5); 8 — prinovozemelsky rear shock absorber (from a motorcycle “IZH”); 9 — carriage of caterpillar tracks (steel pipe 30×2,5 and 22×2); 10,13,15,16 — rollers caterpillar tracks; 11 — bracket; 12 — the caterpillar (rubber conveyer belt); 14 — lugs (aluminum, channels 20x10x2); 17 — tie-rod; 18 — bracket-rocking chair (steel pipe 22×2); 19 —undercut (steel, sheet s); 20 — prinovozemelsky front shock absorber (motorcycle Voskhod); 21 — ski (Vileika from plywood and laminate s5);22 . security; 23 — sprocket caterpillar tracks; 24 — a strainer (from a motorcycle “IZH”); 25 — brake disc; 26 — duplica rocking steering device; 27 — a brake caliper device
1 — motor mount (steel, pipe 30×2,5); 2 — steering column (steel, pipe 25×2,5); 3 — bracing (steel, pipe 18×2); 4 — poluchaut (steel, sheet s); 5 — bracket bearing of the housing; 6,9 — brackets of the axes of the rollers (steel, s); 7 — spring-hydraulic shock absorber (from a motorcycle “IZH”); 8 — longitudinal swinging of the carriage (steel, pipe 30×2,5); 10 — axis bracket carriage (steel, sheet s); 11 —base frame (steel, pipe 30×2,5); 12 — steering arm (steel, sheet s6); 13,15 — reinforcing gusset plate (steel, sheet s); 14 — front beam of the frame (steel, pipe 40×2); 16 — steering column; 17,19 — cross member (steel, steel 30×2,5); 18 — bracket bearing housing (steel, sheet s); 20,21 — the fixing points of the engine
Design shaft of caterpillar tracks:
1 — wheel hub brake disc; 2 — bracket bearing housing; 3 — bearing housing; 4 — ribbon of caterpillar tracks (conveyer belts); 5 — fastening grantsa-chain (the bolt of M6 with nut and washer); 6 — mount bracket (M6 nuts and washers); 7 — bracket (steel, rod d6); 8 — grouser (aluminum, channels 20x10x2); 9,13 — standoffs (steel, pipe 22×2); 10 — ice rink (hub-wheel moped);
1. safety (steel pipe 14×1,5); 2,3 — mount arc security (self-tapping screws d5); 4 — stiffener (birch, rake s10); 5 — spring-hydraulic shock absorber (motorcycle Voskhod); 6 — bracket steering shaft (steel, sheet s4); 7 — bracket-rocking chair (steel, pipe 22×2); 8 — cutting (steel, sheet s3); 9 — the base of the bracket-plastic (steel, channel 150x50x4); 10 — M10 nut; 11 — washer; 12 — axis (pin M10); 13 — the case of the hinge (steel, pipe 30×2,5); 14,20 — shock mount (M8 bolts with nuts and lockwashers); 15 — flange arc safety (steel, sheet s2); 16 — ski (Vileika of three 5-mm plywood blanks and soles of 1 mm laminate); 17 — the lower support of the shock absorber; 18 — mounting (bolt M6 with nuts); 19 — mount bracket base-rocking (bolt M6 with nuts)
Ski snowmobile vyklevyvajutsja of plywood pieces — each will require three 5-mm plate. The sole of the ski is laminated plastic, (such is coated kitchen furniture), having good sliding properties and wear resistance. Vileika ski is the simplest slipway — a thick Board nailed to the front part of the bars, the shape of which follows the curvature of the bent ski socks. Each ski has two undercuts — steel plates with a thickness of 3 mm mounted on the lateral sides of the ski.
Each ski equipped with a shock-absorbing device consisting of a bracket and rocking motorcycle shock absorber (for this approach spring-hydraulic shock absorber from “Sunrise”). In the front part of each ski is mounted a tubular arc security.
The steering mechanism of a snowmobile consists of a handlebar of a motorcycle type, steering column duplechin steering lever and a pair of rods with “the Zhiguli” ball joints connecting the steering arm with swivel bipod left and right steering columns. When drawing kinematics of steering it makes sense to use simple models in a convenient measuring scale from plywood or even thick car-
colors — they will accurately pick up the geometric parameters of the rods and levers in accordance with the actual size of the snowmobile.
The fuel tank is a 10 liter aluminum canister, which is embedded standard motorcycle fuel cock suck. To this end, the canister will have with TIG weld it to the threaded bushing.
The body of the snowmobile, consisting of a base and hood, wikiepedia of fiberglass and epoxy resin. This uses the simplest fool out of plywood, boards and plaster. A separating layer when Vileika will serve as parquet wax-mastic is deposited on the dummy and raspolirovka to Shine. During molding of the housing first wikiepedia base — pre-boob using plywood plates and regular clay at the future site of the connector housing is constructed by the flange, which would serve as a form for flanging. After vyklicky plywood and clay are removed, flanging cropped to a width of 30 mm, is sealed with a ribbon-tape, and only after that starts forming the hood of the housing.
After curing of the resin part of the housing removed from the boob, and if necessary, increase the inside stringers of slats, which are fastened to the shell with epoxy putty and small screws. Next, the hood and base cut a hole under the cylinder of the engine and the front cross beam.
The surface finish of the housing is performed using autosplice and enamel cold drying. The connection of the housing parts is made of nuts and bolts. Flanging are covered with decorative aluminum profile channel.
On the frame of the snowmobile installed panels from 10 mm plywood, impregnated in two steps with hot linseed oil. The locations of the legs of the driver and passenger glued strips of corrugated rubber.
Management snowmobile — motorcycle type grip throttle and a clutch lever on the handlebars and the brake pedal and shift the transmission. Electrical equipment includes a motorcycle headlight and taillight.
The snowmobile seat is a plywood box, assembled on aluminum parts and bolts and nuts and mounted on police. On top of the box is glued to the cushion of rigid foam, and this entire site is covered artificial leather.
The windshield is made of plexiglass. For attaching it to the body uses the curved form of the hood dural area. To fit the glass to the hood it makes sense to use a cardboard template and fit it, you can easily carry the resulting circuit on a Styrofoam blank.
