Embodiment Construction

[0033] Regarding the embodiment of the present invention, taking the case of applying the shock absorber housing structure of the present invention to the vehicle front structure as an example, refer to Figure 1 to Figure 5 Describe in detail. In the description, the same reference numerals are assigned to the same elements, and overlapping descriptions are omitted. In addition, when describing a direction, it demonstrates based on front-back, left-right, up-and-down seen from the driver of a vehicle. In addition, the vehicle width direction is synonymous with the left-right direction.

[0034] figure 1 It is a perspective view of a vehicle front structure of a vehicle having the damper housing structure according to the present embodiment, viewed obliquely from the front right. Such as figure 1 As shown, the vehicle V is a so-called automobile, and includes: a power room P that accommodates a power unit such as an engine; a vehicle compartment R that serves as a passenge...

Abstract

Provided is a damper housing structure body with which, while avoiding increased mass and increased man-hours, it is possible to ensure bonding strength of a damper housing and a damper base. In a damper housing structure body (1), an upper edge of a damper housing (2) and a damper base (3) are bonded by spot welding. The damper housing (2) presents a U-shape having an aperture on a vehicle external side in plan view, and comprises a flat part (24) in a gap between a front-side partition (22) and an interior-side partition (21). The flat part (24) further comprises a plurality of weld points (51, 52) which are aligned in the fore-aft direction of the vehicle. Adjacent weld points (51, 52) have mutually overlapping welds.

Description

technical field [0001] The present invention relates to a shock absorber housing structure in a vehicle and a method for manufacturing the shock absorber housing structure. Background technique [0002] The suspension device (suspension) of the vehicle is supported on the shock absorber housing via the shock absorber base serving as the upper surface of the shock absorber housing. Patent Document 1). The shock absorber base and the shock absorber housing are input with a load when the vehicle is running, especially when a large load is input when driving on rough roads, and therefore considerable joint strength is required. [0003] The shock absorber base is joined to the upper edge of the shock absorber housing by spot welding. It is known that the load when the vehicle is running is concentrated on the front corner portion of the upper edge of the U-shaped shock absorber housing in plan view, but such a portion cannot be welded, and it is difficult to ensure joint stren...
