car body structure

Abstract

The invention provides a body structure of a car, which not only avoids increase of number of parts or weight but also allows a damper shell and a balancing rod made from aluminum alloy to be connected firmly. A plurality of ribs (25b), which extended from center radially, are formed on the upper surface of the damper shell (25), made from aluminum alloy, on the upper end of a bearing damber; a mounting base (25c) connects adjacent ribs (25b) among the ribs; one end of the balancing rod (27) is connected to hte mounting base (25c). By means of the ribs (25b) for beraing the load at the connection position between one end of the balancing rod (27) and the upper surface of the damper shell (25), the wall thickness of the whole upper surface of the damper shell (25) is reduced and further weight is reduced, and the balancing rod (27) is connected firmly.

Description

technical field

[0001] The present invention relates to an automobile body structure in which one end of a balance bar (tower bar) is connected to an upper surface of an aluminum alloy shock absorber housing that supports an upper end of a shock absorber. Background technique

[0002] In the following Patent Document 1, there is known a structure in which a bracket is provided at the central portion of the instrument panel upper member in the vehicle width direction, and is connected by a pair of left and right suspension support bars (stabilizer bars) arranged in a V shape. The left and right damper housings and the bracket thereby increase the rigidity of the damper housing against the load applied from the front wheels via the damper.
