    This invention relates to mechanical engineering, in particular to plastic springs. The purpose of the invention is to increase the reliability of the spring by increasing its strength. In a plastic leaf spring with a central part 3 of the ear and connecting parts at least one of which forms an end part, the tensile strength is increased due to the introduction of two flat reinforcing elements 6 located on two opposite sides of the end (end) part of the spring. At least one of them is coupled to the transition groove 5, and thus the reliability of the spring is increased. 2 3.p. f-ly, 2 ill. SU) with

    This invention relates to mechanical engineering, in particular to plastic springs.
    The purpose of the invention is to increase the reliability of the spring by increasing its strength.
    Fig, 1 shows the eye of the spring of fiber-reinforced plastic material, a longitudinal section; in FIG. 2, the same plan view.
    A plastic leaf spring contains at least one section of a lug 1 of a spring or a case of a spring made of fiber-reinforced plastic material, such as fiberglass-reinforced epoxy resin, located at one end of the spring and consisting of a layer 2 of constant thickness with a central part 3 of the ear and two connecting parts 4, and at least one of the section forms the end part of the spring or is connected to the end part of the spring, and the connecting parts 4 are arranged mutually in parallel and are associated with the central hour New 3 ears with the formation of at least one transition groove 5, two flat s sils 6, located on opposite sides of the end (end) part of the spring, and at least one of them is conjugated with the transition groove I 5 and it is shape-limiting and / or frictionally connected with each other and / or with the spring end.
    The connecting sections 4 of the spring tab 1 of the spring, which encloses the opening of the spring tab, can be interconnected to form the terminal part of the spring. In addition, the two connecting parts of the 4 layers of the spring lid can be attached by two flat side surfaces to the end of the spring and are connected to this end of the spring by means of reinforcing elements (not shown).
    The reinforcing elements 6 can be made of steel plates with rounded edges 7, by means of which they fit tightly into the grooves 5 and are connected to each other and to the spring end section with the help of bolts 8, which pass through the corresponding holes (not shown) in

    elements and in the section of the spring end, and thereby ensures a strong mechanical fastening, the reinforcement elements 6 significantly reduce the destructive power of the leaf spring under tensile load. The central part 3 of the spring as if covers the sleeve of the lug 1 of the spring. The spring bushing can also be made of fiber reinforced. plastic material.

    Claims (2)
    [1]
    Invention Formula
    . . A plastic leaf spring containing at least one spring eye section or a spring reinforced plastic fiber material, located at one end and containing each or every layer of a constant mass with central and two connecting parts, at least one of the latter forms The end part of the spring or connected to it, the connecting parts are mutually parallel and are connected with the central part of the ear with the formation of at least one. transition groove, characterized in that, in order to increase reliability in operation by increasing its strength, it is equipped with flat reinforcing elements located on opposite sides of the end part of the spring, and at least one of them is connected with the transition groove, and both reinforcing elements limit the shape and / or frictionally connected to each other and / or to the spring retainer.
    [2]
    2. The spring according to claim 1, characterized in that the connecting portions of the spring layer of the lug of the spring, which covers the hole of the spring lug, are interconnected to form the terminal part of the spring,
    3, Spring according to paragraphs 1, 1 and 2 with the fact that both connecting parts of the spring layer covering the hole of the spring eye abut two flat side surfaces to the spring end and are connected to this spring end by reinforcing elements and bolts.
