Embodiment Construction

[0017] figure 1 A spring plate according to the invention is shown, wherein the surface 1 facing the vehicle suspension spring (not shown) is shown in perspective. The surface 1 has an end stop 10 on which the end face of the vehicle suspension spring formed as a helical compression spring is supported during operation. Furthermore, there is a region 3 extending from the spring plate material and forming a defined support point for a vehicle suspension spring (not shown). In the exemplary embodiment shown, the spring plate is produced from a sheet metal semi-finished product by forming, and the extension area is also produced by forming.

[0018] The extension area 3 has the form of a bridge and supports a sheet metal element 4 acting as a corrosion protection element. Thus, the sheet metal element 4 is arranged on the support point 2 and is in contact with the spring in all operating states, ie in particular in all spring deflection states of the vehicle suspension spring. ...

Abstract

The invention relates to a spring plate for supporting a vehicle suspension spring, the spring plate having a surface (1) facing the vehicle suspension spring and at least one support point (2), wherein the spring plate has a A region (3) extending in the direction of the vehicle suspension spring and forming a support point (2), and wherein a sheet metal element (4) acting as a corrosion protection element is fastened to the extending region (3) and is in all operating states with the Vehicle suspension spring contacts.

Description

technical field [0001] The invention relates to a spring plate for supporting a vehicle suspension spring, as for example used in a suspension strut for a motor vehicle. Background technique [0002] In the case of sprung shock absorbers and McPherson suspension struts, the body springs (vehicle suspension springs) are usually supported on spring plates fastened to the shock absorber tubes. Coating of vehicle suspension springs to protect them from corrosion. During actuation, relative motion occurs between the spring and the spring plate as the spring deflects and rebounds, and causes damage to the coating of the spring. Springs with damaged coatings are susceptible to corrosion. Vehicle suspension springs are exposed to dirt and moisture in the wheel suspension area, which promotes undesired corrosion. [0003] In order to reduce the risk of corrosion, DE 10 2005 021 765 A1 proposes a bearing device for vehicle springs, which comprises a spring plate with a plurality of...
