    1. A rolling diaphragm for an air spring constructed as a double cone and providing at least two inserts having mutually crossing fibers, characterised in that in an unpressurised condition the diameters, changing along the generator, proceeding from the lower and upper edge regions of the diaphragm (2), and enlarging to mutually different degrees, define a profile in the form of a doubled truncated cone, and in that the value of the cord angle along the generator of the diaphragm profile changes continuously, the cord angle increasing in both directions from the maximum diameter of the diaphragm.

    This invention relates to automotive construction, in particular to elastic suspension elements.
    The goal is to increase reliability.
    FIG. I presents the elastic element, the total pid | in fig. 2 -the arrangement of the cord layers.
    Elastic elastic element contains elastic shell 1, made in the form of truncated cones 2 and 3 with a common large base. These cones are reinforced by intersecting layers of cord, the angle ot of inclination of the cord fibers to the parallel drawn through a certain point varies from 25–40 to 40–50 in one direction and the other.
    The taper of both truncated cone

    While the vehicle is moving, its operation is similar to that of a pneumatic elastic element,
    However, in the general case, vehicle manufacturers, in addition to ensuring reliable depreciation, face the problems of adjusting pneumatic elastic elements to lift any part of the suspension. In addition, when a large amount of light and sensitive to the load of cargo is transported 45 and the vehicle is full. practically absent, the axis (for reasons of depreciation it raises
    Keing a vehicle to wheels can lead to harmful compression deformations.
    A similar critical condition occurs when changing wheels, in garage conditions, i.e. in the most favorable conditions, when the entire cusp immediately rises, as a result of this, a reduced excessive pressure and a large amount of pressure is generated in the elastic element. great volume
    In this elastic element, due to the cord structure, the problems that provide the most favorable cushioning are solved with prevailing tensile forces and smaller compressive forces. With a small pressure. The compression of the cushion did not cause damage. This increases the service life of the cushion without the need for a separate outer jacket or additional attachment (sa)
    As a result of the change in the profile of the elastic element due to the mutual double cone, cord angles arise. They strengthen the cushion and protect it from harmful deformations (similarly, the corrugated plate is harder than smooth).
    with during work, At a large number of cars, trailers, tons of caches, etc. The use of air springs comes to the fore, because in this way you can definitely achieve the best damping characteristics.
    When a vehicle is in operation, an extreme depreciation condition often occurs when the air pressure in the air spring drops to a relatively small value. When transporting by sea, railroad), a state without excessive pressure also occurs. In this state, the rise of the vehicle is less than the value of the atmospheric pressure inside the airbag; as a result,
