Abstract

In order to enable a reduction in the weight of a bracket which forms part of a suspension strut, the bracket is press formed from sheet metal in a manner which forms first and second main sections, a bridge-like connecting section and a U-shaped connection flange which extends along all three of the just mentioned sections. The bracket components are configured so as to have two or more hem-cylindrical shaped reduced diameter portions which fit against the outer periphery of a strut tube and which have edges along which welds can be formed. Box-like projected sections defined in the two main sections between the hemi-cylindrical portions define spaces which have rectangular cross-sections about the periphery of the strut tube.

Dependent claims

A bracket for use with a suspension strut comprising:

first and second side members, the first and second side members being adapted to extend axially along the external periphery of a tubular member which forms part of the strut;
a connecting member which is formed integrally with the first and second side members;
an essentially U-shaped flange which extends along the first and second side members and the connecting member, said U-shaped flange being formed with at least one pair of connection bolt holes, which are coaxial and located opposite one another;
a first essentially hemi-cylindrically shaped portion formed in the connecting member which is adapted to contact the tubular member and to have an edge welded to the tubular member;
a second essentially hemi-cylindrically shaped portion formed in the first and second side members which is adapted to contact the tubular member;
and
first and second box-like projections in said first and second side members defining spaces between the bracket and the tubular member respectively, the first projection being provided between said first and second hemi-cylindrically shaped portions, the second projections being provided adjacent the second hemi-cylindrically shaped portion opposite the first projection.
