RU2326009C2 - Test traction wheel of amphibious vehicle - Google Patents

Abstract

FIELD: machine building.

SUBSTANCE: invention pertains to motor-car construction, in particular to amphibious vehicles with two driving axles. The test traction wheel of the amphibious vehicle consists of a tyre with a protector, a hub and uniformly arranged streamlined vane wheels. The vane wheels are installed on a disc, made from steel, which is fixed to the hub of the wheel using bolts going through openings on the disc. The tails of the vane wheels are curved in a radial direction.

EFFECT: simplification of the structure and operation of the wheel and increased efficiency of its use, increased lift coefficient and speed of movement on water.

Description

The invention relates to the automotive industry and can be used in sea and river transport.

Known amphibian from SU 1435492 A1, 11/07/1988, containing a propulsion device that is converted to move by land and water and includes a drive wheel with blades, covered from above by a hydrodynamic casing with a water jet pipe at one end. To facilitate the transfer of the propulsion device from one driving mode to another, the casing includes at least two wings that are telescopically connected to each other with the possibility of relative rotation in the longitudinal plane and forming in the working position an annular cross-sectional casing of an open profile open to the center of the wheel with the formation channel gradually increasing the bore to the specified end, bearing the pipe.

The disadvantage of this invention is the relative complexity of the design. Remounting is required from land to water and from water to land. The design provides for the vehicle to move up and down, so the pipe does not change its position.

One of the main disadvantages is remounting.

In addition, the disadvantage is the insufficient use of reactive power to lift the car above the water and the insufficient speed.

The technical result of the invention is to simplify the design and operation of the wheel, increase the efficiency of its use, increase the coefficient of lift and speed on water.

The specified technical result is achieved in that the test drive wheel of an amphibious vehicle contains a tire with a tread, a hub and evenly spaced streamlined impellers. The impellers are mounted on a disk made of plate steel, which is attached to the wheel hub by means of wheel bolts through holes made in the disk. The tail parts of the impellers are bent in the radial direction.

On the disk of plate steel 5-6 mm holes are made according to the number of bolts on the hub. Just as the wheel rim is attached to the hub, a disc is mounted on these bolts over the rim with streamlined and evenly spaced impellers / vanes /, oriented by the suction portions of the impellers water, and their tail parts are equally spaced around the circumference of the disk and smoothly bent in the radial direction. This fold of the impellers provides an increase in the lifting force and speed of the car on the water.

New is the bending of the tail of the impellers in the radial direction.

Figure 1 shows the wheel in plan;

figure 2 is a section of the wheel along AA, where the drive shaft, axle, hub, rim of the wheel with the tire, the disc, bolted, and perpendicularly attached streamlined impellers with bent ends from the center in the radial direction are visible on it.

On the hub 1, with the help of bolts 2, a wheel rim 3 is attached with a tire 4 and with a tread 5. On top of the rim 3, a disk 6 is attached to the same bolts 6. On the disk perpendicular to its plane around the circumference, impellers 7, which are streamlined in cross section, are bent at the periphery disk bent ends of 8 impellers. The hub is attached on an axis 9 located in the bridges 10, on which the brake pads are attached / not shown /.

At the same time, the car should have a streamlined streamlined body with a high threshold of doors that may open upward, a hatch that opens upward, hinged seatbacks and a fan that creates excessive pressure when the doors and hatch are hermetically closed.

Technical and economic advantages of the proposed technical solution are as follows:

- in the summer unload roads, bridges;

- shortened roads, for example, from Samara to Syzran about 100 kilometers, from Vladivostok to Tavrichanka or to Ussuriysk for 50 kilometers;

- Amphibious cars will find application in sports, fishing, military affairs and on vacation.

Initial tests are carried out on a water stand at a certain weight of a car with a driver and fuel. The rate of climb is determined at a certain wheel rotation, as well as the tension force of the ropes by dynamometers.

With a satisfactory result of tests in the pool, tests are carried out in reservoirs, shallow lakes, bays and bays. With a satisfactory outcome and these tests, it is necessary to proceed to tests in deep water bodies, rivers, accompanied by a capacious boat, so that under some adverse conditions the boat can receive testers.

Upon successful tests of an amphibious vehicle on the banks of rivers and lakes of reservoirs, provide ramps that go into the water at a depth of 0.5 meters.

The proposed design does not provide for remounting. If a car hits a road curb with a wheel, the wheel will ride along the curb on the impellers.

Claims (1)

A test drive wheel of an amphibious vehicle containing a tire with a tread, a hub and evenly spaced streamlined impellers, characterized in that the impellers are mounted on a disk made of plate steel, which is attached to the wheel hub via wheel bolts through holes made in the disk, while the tail parts the impellers are bent in the radial direction.
