ITS ELEMENTS – LAND AND WATER

ITS ELEMENTS - LAND AND WATERMoscow musician D. T. KUDRYAKOV among Amateur designers known as the author of a unique car is amphibious “Triton” — one of a kind vehicle that is registered simultaneously in two state inspections: car (GAI) and for small vessels (GIMS). Our regular readers may recall the publication of “Planing… car” (“modelist-Konstruktor” No. 5 of 1996), containing quite a full description of the construction of the “Triton”. In it the author shared his approach to solving complex technical problems, which allowed him to create a vehicle equal in their performance on land and on water.

The performance of creativity. Kudlackova it is difficult to question. This is evidenced by the present publication, where Amateur designer offers interested readers a description of his new amphibian. It looks similar to the predecessor. However, “Triton-2” —really a new car: she has a modern front-wheel drive layout, more simple, and hence reliable actuators, hydraulics in the control system and so on.
 
With regard to the motives that forced the former musician, now retired, is quite troublesome and by today’s standards, he does not hide them: “do Not sit on pensions! But seriously, did not give rest to desire to make the machine with higher performance capabilities. To test it. Her and yourself.”
 
That’s right: test yourself! Will there be followers?
 
Although “Triton-2” in many respects differs significantly from its predecessor is already known to the readers of “Triton”, nevertheless, he fully inherited all its virtues and performance. That is quite natural, after all, used the principles of design and almost the entire Arsenal of technical means, it works flawlessly on the “Triton”. The same type and design of the wheel suspension, the same scheme steering gear, the same quick-release couplings, allowing in a matter of minutes to turn the amphibian into a “clean” boat, and more. So, not to be repeated, offer to contact that publication of “Planing… the car”, where the drawings and detailed description common to both “newt” nodes and mechanisms. Familiarity with these materials would be useful as they contain complex information, the development of which is this article.
So, what’s new in the “Triton-2”? Externally, the amphibian is not so extravagant. She reduced wheel track (which took some of the stress twisting corps), no wings, wheels with suspensions fit into the dimensions of the enclosure, on the left side “cut” a door for the driver (only used on land).
 
However, the approaching appearance of the machine to the current automotive standards, paid for by the complication of the design of the tool body. Shields wheel arches and driver’s door ripped side elements for longitudinal stiffness, had the power set to introduce two additional longitudinal — parallel sides at a distance of 300 mm, equal to the depth of the niches. To these spars and rear wheel suspension (“Triton” such burden fell on the side). In the rest of the power set case is similar to the prototype it is based on frames and rails made from oak and pine beams with different cross-sections and paneling, walls, knize carved from Aviaenergy.

The lower part of the body, like the old amphibians is a solid sectioned box, the platform of high hardness — “support the bottom”. All of his spacey isolated from each other, since the frames are blocked (except for the lower branches of the duct) plywood bulkheads, equal in height to the bottom longerons.

 
Side (driver’s) door is a space frame car and a gasket of elastic rubber. It is located in the wide spacey between the frames 3 and 4. The doorway does not affect the power of the elements “the bottom of the carrier” because the bottom edge of it above the water line by 100 mm.
There was another problem with the rear wheel arches. Invading the traditionally untouchable “boat” bilge area, they reduce and distort it a planing surface. All existing in camerascreen rules this can not be done without the risk of reducing the hydrodynamic qualities of amphibians. And yet, if we take into account the results of the experiments conducted in experimental pool Calarossa United States Navy by the famous American expert in the field of hydrodynamics of high-speed vessels E. R. Clement (the magazine “Boats and yachts” № 66, p. 22), rear wheelhouse will be not so malicious.
 
 
The Designation “Triton-2”
 
Amphibian can be used as the vehicle output or a long day of tourism on combined water and land routes. With appropriate equipment it will be used in rescue services, coast guard, expeditions.

Clement it was found that the body of the glider should have a narrowing in the stern, reaching up to 30…35% of the maximum width at the cheekbone. It is logical to assume that the aft sections of the bottom of the “Triton-2” reserved wheel niches, almost serve the same purpose — reducing in the direction of the stern planing surface of the bottom.
 
For the approximation of practical to theoretical results (Clement, narrowing in the feed should be smooth, and the “Triton-2” it’s speed) the bottom is complemented by a full gidroliza, two short longitudinal side steps and spray deflectors.
 
The unusual layout of power plant and transmission new amphibious: engine (GAZ-31029) — in the stern, and the transmission with the differential in the fore part of the body. They are connected to a long well balanced propeller shaft with intermediate support, and an uncoupling device, and a Cam clutch. On the other hand to the engine through another divisive device (like a dog clutch) docked rotor jet. Both clutches have a welded body filled with fluid. Management is focused on the workplace of the driver.
 
This layout demanded special care in the removal of excess heat from the power plant. Dual system and liquid-air cooling “Triton-2” reinforced with additional radiator of small height, located at the beginning of the duct (before frame 1), extending to the motor through the housing under the trunk and floorboards. Radiator, and a heater connected to a three position valve to the supply hose from the engine, so you can enable or radiator, or in series, the heater and the radiator. For the latest on the rubber seals installed manobrista the transom, controlled from the driver’s seat: when driving in the rain and on the water in breezy weather it can be closed. In this case, the radiator is cooled by natural irrigation.
 
However, the most important feature of the “Triton-2” is the absence of his transmission of “intermediaries” — reducer and chain wheel actuators. The undoubted advantage: reduced number of components and parts nezapadnogo of manufacture, reduced noise, simplified maintenance, and reduced, finally, the cost of the project.
 
Let us consider the individual units.
 
Important place in the construction of a new amphibian belongs to the suspensions of the wheels. They rise out of the water or fall now is not a cable winch, and hydraulic cylinders double-acting with warning lights on the dashboard. Accordingly modified and the mechanical part of the drive. The upper plate spring and damper pivotally connected with the carrier control, set them in working position (in the reference slot on the case), does not require any fixing — kinematics of the suspension is such that when the load the spontaneous movement of the wheels in position “afloat” is excluded.
 
The multifunctional nature of the work the front suspension requires a strict linking of all the components. In particular, the configuration of the lower extremities of levers, fitted with spherical bearings have been thoroughly proven on the layout, without any hesitation carried out the third function of the front-drive amphibious — free upgrade the wheels to a great height — 600 mm. the Last is taken from the VAZ-2108 with hinges of equal angular speeds (Shrus). With the differential from the ZAZ-968 joints associated homemade a telescopic rod with sliding slots (speed up to 200 mm). This ability to stretch allows the rod to remain linked with the wheels when climbing out of the water. Recall that the performance of the suspensions is ensured and the special kinematics of the steering gear, is entirely borrowed from the “Triton”.
 
From the differential installed universal joints with the angle of the fracture up to 44°in the position of the wheels afloat. Working the same angle hinges — 2…4°. (They are currently working on installation and Shrews from here “eight”. I think they are more reliable gimbal.)
 
Pay attention to another very important feature of front drive for amphibians (with niches in the body or without floating or gliding): when lifting the wheels and levers of suspension, and an extendable axles are almost the same characteristic property of the bow of the hull V-shaped, and small holes in the casing for the lower fragments of the semi-axes do not impair driving performance amphibious, as when planing the front of the case is literally flying over the water.
 
The mechanism of uncoupling of the propeller shaft — homemade Cam clutch (only one detail in its factory design front cover the regular transmission GAZ-31029). It is attached to the free end of the clutch housing of the engine is exactly the same as PPC, or four studs.
Uncoupling mechanism of the water jet partly follows the design of a Cam clutch. It is attached to the front end of the crankshaft via the drive flange of the generator and water pump. Three regular bolts flange added three more — with thread M10x1. Ratchet replaced the bolt with a conventional head.
 
The clutch housing has two angled bracket that he is using a special adapter made to place the console attached to the engine block (used bolts to timing cover and studs macropodia).
 
To compensate for movements of the engine relative to the powertrain in the line of transmission shafts and water jet introduced universal joints with sliding spline joints, and to reduce noise and mitigate shock loads — elastic rubber coupling.
 
Both are operated uncoupling mechanism of the remote cable-drive from the driver’s seat.
 
Brake system the same as on the prototype: a working — hydraulic, dual circuit, with dry connectors hydraulic drives, acts diagonally on all wheels; Parking — cable — only on the rear wheels.
 
From the above it can be seen that front-wheel drive layout, implemented on the “Triton-2”, “embedded” in the body quite naturally. It may be the most rational if not the only possible one, because it allows you to get rid of many intermediate nodes in the transmission of amphibians in General, and gliding in the first place.
 
It seems that inherent in “Triton-2” creative findings will help Amateur designers when creating a planing amphibian.
