CHAMPION CARDS | MODEL CONSTRUCTION

Circle carting of the Palace of pioneers of the Bauman district of Moscow one of the leading in our country. The team of the Palace is constantly among the strongest kart USSR. But a good reputation in the circle is responsible not only for his sporting achievements. He is known for his homemade racing micro cars. It would seem that anyone today could surprise card build in any more or less equipped laboratories. However “kruglikovsky” (by the name of the head of the circle) of the machine compares favorably to similar.

First, appearance. Hard to believe that this is not the factory instances, because the workmanship and finish is excellent. Second, the particular reliability and maneuverability through the use of original design solutions.

Innovations that help the Pets of Konstantin Ivanovich Kruglikova win prizes, here don’t hide behind seven seals. In 1982, “M-K” published the latest construction map of “pioneer”. This time readers are invited to little micro-car class “the Union” (age group “Junior”). It meets the highest international standards and is suitable not only for the young men 16— 18 years, but adults acting classes, “Union”, A, B and C2.

On machines of this design drove the members of the club, champion of the VIII Spartakiad peoples of the USSR, 1983, Alexander Teplyakov, three-time champion of the Soviet Union Oleg Tregub, the winner of the all-Union competition in 1981 among young men Oleg Blazevski, as well as master of sports of international class, member of the USSR national team, two-time national champion Mikhail Ukhov, the repeated prize-winner of several national Championships Michael I. Gostelow many others.

“Junior” is structurally different from “Pioneer”, but the technology of making both the same. Therefore, a detailed description of the preparation of templates, equipment and materials, and methods for flexible pipes and the manner of welding the frame I is lowered and I address the reader to the article “pioneer” cards for beginners” (“M-K” No. 4 and 5 in 1982) to focus instead on the elements inherent in only “Junior”.

Map “Junior”:

1 — lateral bump stop, 2 — accelerator, 3 — front bumpers, 4 — brake pedal 5 — brake disc 6 — left front brake machine, 7 — block brake-cylinder, 8 — clutch lever, 9 — lever gear shift 10 — rear bumper.

Frame card:

1 — pin installation of the front bumper, 2 — bushing pedals, 3 front beam, 4 — ear mounting front bumper, 5 — pivot suspension lug, 6 — ring gas harness cable, 7 — pin installation of the steering column, 8 — support seat, 9 — bushing mounting side bumpers, 10 — bracket rear brake machines, 11 — rear axle bracket, 12 — spar, 13 — attaching the brake cylinders 14 — pole for steering column, 15 — console support, 16 — rings for the engagement springs of the pedals, 17 — front mounting points Polycom, 18 — rear attachment points Polycom, 19 — bearing axis of the shift lever, 20 — medium beam 21 is an additional side bar, 22 rear beam 23, the installation location of the rear bump stop set, 24 front baffle, 25 — lateral bump stop, 26 — rear bumper.

Brake master cylinder:

1 — cover 2 — body, 3 — spring 4 — piston 5 — sleeve 6 — washer, 7 — podparser, 8 — retaining ring.

Fundamental differences frame that she’s not wedge-shaped and has pivot lugs, side bumpers, additional side member and the three legs of the rear axle. Pedals — two: accelerator and brake (steel pipe ZOGGS diameter 12X2). The clutch pedal is missing, it was replaced by a lever on the steering column under the left arm of the driver. Column also from pipe ZOGGS installed approximately the same as “Pioneer”, only its front support located on the front beam, and channel on the console. In the hub last pressed bearing SHS-10, which allows to change the angle of the column. The latter is held up in a nylon or Teflon bearing.

With swivel column connected steering rods of steel pipe with a diameter 14X1,5, pull on the ends have right and left thread to adjust the camber.

Unlike the map of the “pioneer” of the pivot lugs knuckles here belong to the frame — welded to the ends of the front beam. Next to them are the upper mounting points of the front bump — ears, and the bending beam — low points: pins.

The side bumpers are fixed at the frame rails with two bolts each and protect the wheels against foreign objects. Rear bumpers structurally not much different from being on “the Pioneer”, and the means of fixing them to the frame are the same (see Fig. 5 in the “M-K” No. 4, 1982).

But back to the steering knuckle. It consists of the axle shaft, machined from steel 45, pivot and spacer bushings, brake bracket cars and the bipod is all steel 20.

The axle shaft is worn out the front wheel hub, which is structurally different from the “pioneer”: to one its end is fastened the brake disc of D16T or V95 and the other drive wheel, carved from a single piece of the same material.

According to the specifications of the map class “Union” that belongs to “Junior”, provides the hydraulic brakes of the rear and front wheels. But the drives are separate from the two identical brake cylinders located on the left longitudinal member of the frame near the seat.

Body and lid of the cylinder is made of D16T or V95, and the pistons and the pistons— made of cast iron SCH21-40. The latter have lunoobraznye holes for Cam followers connected by a rocker and the rod with the brake pedal. Hydroright cylinder to the brake servo is fed by plastic tubes.

Although the size and structural performance front and rear brake cars are different, the principle of their action is the same. The same and the materials used. The calipers are made of D16T or V95, pistons made of brass, and brake pads, screws of attachment and axle of steel 45. Friction plate of material “ferrodo”.

The design of the rear axle basically repeats itself (see Fig. 6 in the “M-K” No. 4, 1982). Slightly changed only the shaft (titanium VT6, VT20 or BT16), wheels (Д16АМ or AMC), hub, sprocket, and brake disc (D16T or V95), the disc (cast iron SCH21-40), and added a third bearing housing (D16T).

Front right brake machine:

1 — caliper 2 — spring 3 — screw mounting pads, 4 — piston, 5 — rubber collar, 6 — brake pad of 7 friction plates, 8 — hole pumping cylinder (at the left of the brake, the shank it to the left of the axis of symmetry of the caliper).

Rear brake machine:

1 — stand, 2 — spring, 3 — screws of fastening plates, 4 — hole for pumping cylinder 5 — piston 6 — rubber cuff, 7 — movable brake lining, the 8 friction plate 9, the fixed brake pad.

On the hub, together with two sprockets made from steel or duralumin with the difference in number of teeth, providing adjustment of the drive under the weight of the card and the rider, engine power and frequency of rotation of the drive sprocket.

On the “Junior” used engine MMVZ-3 115. Mount to frame him the same as any other map. With the installation of a powerful engine (for class C2) should be increased to 30 mm shaft diameter and correspondingly change the dimensions of the bearings.

Fuel tank — two-liter plastic canister located left of the frame behind the seat. But he can be placed under the steering column. Fuel to the carburetor is fed by a pump attached to the rear axle brackets on the right and the additional spars. The fuel pump is driven by an eccentric on the shaft of the rear axle.

About the manufacture and installation of seats, as well as painting and decorating frames and nodes, the map can also be found in the “M-K” № 4 and 5 for 1982
