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 holes 3 are made. The leaf spring can be, for example, a parabolic spring or a suspension spring. The holes 3 may be through holes or blind holes. The holes 3 can be intermediate holes provided in the clamping region or in other regions of the spring leaf 2 , for example in the end regions. The underside 1 of the leaf spring 2 is under compressive stress in the state of use of the leaf spring.

[0038] The leaf spring 2 is preferably made of flat bar steel, in particular of spring steel. The underside 1 of the leaf spring 2 is locally sprayed, in particular shot-peened, in the region around the hole 3 . The distance from the hole 3 to the transition 4 between the sprayed and unsprayed surfaces of the underside 1 is in the range of a few centimeters. During spraying, a first area 5 is created around the hole, which is sprayed uniformly, and a second area 6 ad...

Abstract

The invention relates to a method for producing a leaf spring (2) for a leaf spring, in particular a parabolic spring or a suspension spring, wherein the leaf spring (2) has two end regions, a central area, the upper side under tensile stress in the state of use, the lower side (1) under compressive stress in the state of use, in which at least one hole (3) is made, in the area surrounding the hole (3) spray on the underside (1).

Description

technical field [0001] The invention relates to a method for producing a leaf spring for a leaf spring, in particular a parabolic spring or a suspension spring, wherein the leaf spring has two end regions, a middle region, which is subjected to tensile stress in the state of use. The upper side, the lower side which is under 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 leaf spring for a leaf spring, in particular a parabolic spring or a suspension spring, wherein the leaf spring has two end regions, a middle region, an upper side which is subjected to tensile stress in the state of use, The underside that is compressively stressed in the 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, especially commercial vehicles or trailers (trailers). The requirements of motor v...
