Embodiment Construction

[0037] exist figure 1 The region of the underside 1 of the leaf spring 2 for the leaf spring is shown in , in which a hole 3 is made. The leaf springs can be, for example, parabolic springs or suspension springs. The hole 3 can be a through hole or a blind hole. The bore 3 can be a central bore provided in the clamping region or provided in another region of the leaf spring 2 , for example in the end region. The underside 1 of the leaf spring 2 is under compressive stress in the operating state of the leaf spring.

[0038] The leaf spring 2 is preferably made of flat bar steel, especially spring steel. The underside 1 of the leaf spring 2 is locally blasted, in particular blasted, in the region around the hole 3 . The distance from the hole 3 to the transition 4 between the sprayed and the unsprayed surface of the underside 1 is in the range of a few centimeters. During spraying, a first zone 5 is produced around the hole, which is sprayed uniformly, and a second zone 6 a...

Abstract

The invention relates to a method for producing a spring leaf (2) for a leaf spring, in particular a parabolic spring or suspension spring, the spring leaf (2) having two end regions, a central region, an upper face, which is placed under tensile load when in use, and a lower face (1), which is placed under compressive load when in use. In the method, at least one hole (3) is made in the lower face (1). The lower face (1) is irradiated locally in the region around the hole (3).

Description

technical field [0001] The invention relates to a method for producing a spring leaf for a leaf spring, in particular a parabolic spring or a suspension spring, wherein the spring leaf has two end regions, a middle region, a tension-stressed spring in the state of use The upper side, the lower side which is subjected to compressive stress in the state of use, and wherein at least one hole is made in the lower side. [0002] Furthermore, the invention relates to a spring leaf for a leaf spring, in particular a parabolic spring or suspension spring, wherein the spring leaf has two end regions, a middle region, an upper side which is subjected to tensile stress in the operating state, The underside is compressively stressed in a state of use, and wherein the underside has at least one hole. Background technique [0003] Leaf springs are used in the wheel suspension of motor vehicles, in particular commercial vehicles or trailers (trailers). The requirement of motor vehicles i...
