Description

The invention relates to the field of engineering, and more particularly to the improvement of elastic devices softening shocks and shocks.

Known elastic device described in the book "Automobile: Design Basics: A textbook for universities in the specialty" Automobiles and the automotive industry "N.N. Vishnyakov, V.K. Vakhlanov, A.N. Narbut and others. - 2nd ed. , reslave. and add. - M.: Mechanical Engineering. 1986.- 340 p. (fig. 150, p. 190, fig. 151, p. 191, fig. 157, p. 190) [1].

The elastic device described in the indicated source contains an elastic element in the form of a pneumatic balloon in an elastic rubber-cord casing, a belt-shaped means in the form of a ring, means of fastening the elastic device on one side to the object, and on the other, to the frame or foundation, made in the form of a pressure ring with bolts.

Significant disadvantages of the known elastic device are the lack of reliability and high manufacturing cost.

The reliability of operation mainly depends on the quality of the elastic element, the types and ratios of the components that make up the elastic element, and special technology is required for the manufacture of a pneumatic balloon.

The present invention is aimed at improving the known elastic devices.

The technical result of the invention:

1. Ease of manufacture and low cost.

2. Effective protection of objects from shocks and shocks in any direction.

3. High reliability and long service life.

This is achieved by:

1. The elastic element is made in the form of a toroidal shape from a solid highly elastic material or from a hollow rubber-cord toroidal balloon filled with air or highly elastic material;

2. The torus-encircling means of the elastic element is made integral or composite, consisting of a rope connected to the supporting ring strips by elements or in the form of holes or lugs provided in the annular strips themselves and providing encircling of the torus or in the form of upper and lower groups of pieces of ropes, fixed by the middle part, respectively, with the upper and lower annular strips, and the ends of the pieces of ropes from the inner surface of the torus in the region of the horizontally-diametrical plane and from the outer side of the annular strips along the outer surface of the torus, which is made in the form of a loop and the corresponding upper and lower loops are fastened together along the inner and outer perimeter of the torus with fastening means, for example, in the form of either a rope, or wire, or plates, or brackets, or clamps, etc. ;

3. As another example, the ends of the pieces of ropes are shown, fixed in special non-supporting outer and inner ring slats separately for the upper and lower groups of pieces of ropes with the corresponding ring slats of the lower groups of pieces of ropes, also carried out by fastening means, for example, in the form of or rope, or wire, or plates, or staples or clamps, etc.

Figure 1-5 shows the vertical-diametrical dimensions and a top view of the elastic device with examples of encircling the elastic element - the torus and the fastening of the rope with supporting ring strips.

The elastic device comprises a toroidal elastic element made of a solid highly elastic material (not shown) or a hollow rubber-cord toroidal cylinder 1 filled with either air 2 (FIG. 2) or highly elastic material 2 (FIG. 1), the upper and lower annular supporting strips 3, 4, the encircling torus 1 means from a rope 5 with elements 6, 7, 8, 9.

In figure 1, the rope 5 is connected to the supporting ring strips 3, 4 through the holes 6 in the strips 3, 5 themselves, and in figure 2, 3 through the eyes 7.

In Fig. 4, the rope 5 is provided in the form of upper A and lower B groups of pieces fixed by the middle part C, respectively, with the upper 3 and lower 4 supporting ring strips, and the ends D of the pieces A, B of the ropes from the inside of the corresponding strips 3, 4 are located along the inner surface of the torus 1 in the region of the horizontally-diametrical plane, and with the outer surface along the outer surface of the torus 1, which are made in the form of a loop E and fixed to each other along the inner and outer perimeter of the torus 1 with fixing means 8.

The fastening means 8 are made, for example, in the form of either a rope, or wire, or plates, or brackets, or clamps.

In Fig. 5, the ends of the upper A and lower B groups of pieces of ropes 5 are fixed in special unsupported outer 9, 10 and inner 11, 12 ring strips separately for the upper A and lower B groups of pieces of ropes.

The fastening of the outer 9, 10 and inner 11, 12 ring non-supporting strips of the upper A and lower B groups of pieces of ropes is carried out by fastening means 8.

The tightness of the encirclement of the torus 1 is selected depending on the operating conditions of a particular object, the hardness, elasticity of the material of the torus 1.

In addition, the segments of the rope can be lined, for example, with an elastic element-rubber, or with the help of dyuritic, rubber tubes (not shown in Figs. 1-4).

Instead of a rope 5, there may be rubber or leather harnesses, coil coil springs, and other materials.

Between the non-support ring strips 9 and 11, 10 and 12, special elastic gaskets can be installed.

The presented examples (Figs. 1-4) of encircling an elastic element provide the ability to easily and quickly replace a failing elastic toroidal element under operating conditions, which does not require special experience and skills from staff.

The elastic device shown in figures 1-5, can be arranged vertically from two or more pieces in cases where high smoothness is required, as well as for objects in which the payload varies widely, for example, in trucks and buses.

It is important that an ordinary tire with a camera of vehicles, such as a bicycle, motorcycle, car, aircraft, etc., can serve as an elastic element.

In this case, unsuitable old tires can be used, as well as tubeless tires and tires with highly elastic material in the cylinder instead of air.

The implementation of the specified technical solution from an economic and environmental point of view is relevant.

We consider the operation of an elastic device, for example, as an elastic suspension element of a car.

Here, the elastic device, when the car is moving and on wheel bumps on rough roads, makes elastic connection of the car frame (body) with bridges or directly with the wheels, mitigating shock and shock due to air compression 2 or highly elastic material 2.

When the elastic device is operating, the encircling elastic element - torus 1 means-rope 5 also serves as an anti-convex means of the torus shell, and with the tensile forces of the elastic element, the entire load is perceived by the encircling rope 5.

Thus, the girdle 5 provides the reliability and durability of the elastic device as a whole, while the well-known air balloons ([1] -190, Fig. 150 c) are short-lived and quite often burst and collapse in the region of the pressure rings, and are also significantly dependent on quality and the composition of the material of the cylinder.

These features of the elastic device provide the possibility of its application in various objects to reduce noise, vibration, shocks and shocks.

The novelty of the invention is revealed from comparison with the prototype and is as follows:

1. The elastic element is made of a toroidal shape from a solid highly elastic material or a hollow rubber-cord toroidal cylinder 1, filled either with air 2 (Fig.2-5), or highly elastic material 2 (Fig.1).

2. The encircling elastic element - torus means is made integral (Fig. 1) or composite (Figs. 2-5), consisting of a rope 1 with straps 3, 4 connecting the supporting rings, or in the form of holes 9 (Fig. 1), or lugs 7 (figure 2) provided in the annular upper 3 and lower 4 support strips, providing a girdle elastic toroidal element 1.

2.1. The girdle is made in the form of upper A and lower B groups of pieces of rope (Fig. 4), fixed by the middle part C, respectively, with the upper 3 and lower 4 supporting ring strips, and the ends D of the rope pieces from the inside of the corresponding ring strips 3, 4 are located along the inner surface of the torus 1 in the region of the horizontally-diametrical plane and on the outer side of the annular strips 3, 4 - on the outer surface of the torus 1, which are made in the form of a loop E and fixed (the corresponding upper and lower loops E) to each other on the inside the lower and outer perimeter of the torus 1 with fixing means 8;

2.2. The ends of the pieces of ropes A and B are fixed in special non-supporting outer 9.10 and inner 11, 12 ring bars separately for the upper 9, 11 and lower 10, 12 pieces of ropes (figure 5), and the fastening of the rings 9 with 10 and 11 s 12 is carried out by fastening means 8, which for both FIG. 4 and FIG. 5 are made in the form of a rope or wire, or plates, or brackets.

Thus, the invention meets the criterion of “novelty”.

No other resilient devices with the above advantages are known.
