Problems solved by technology

However, since sufficient dimensional accuracy cannot be obtained for the distance between the shafts of the bearing parts at both ends, which requires particularly high dimensional accuracy, there is a problem that a large number of cutting processes must be performed after casting to ensure Dimensional accuracy or casting must be inspected for internal defects, resulting in increased work steps and manufacturing costs

Abstract

The present invention provides a suspension arm made of an aluminum alloy extruded profile having a portion forming a bottom portion (43), portions forming at least two vertical walls (41, 42), and a horizontal rib (44) which connects the two vertical walls, wherein a suspension part lower end support portion is formed between the two vertical walls or at the bottom portion by removing a part of the horizontal rib. It is preferable to gradually change the interval between the two vertical walls in the portion in which the horizontal rib is removed.

Description

technical field [0001] The present invention relates to suspension arms for vehicles. Background technique [0002] When a vehicle makes a left turn, the Figure 24 As shown, a centrifugal force G acting rightward in the vehicle width direction is generated. This centrifugal force G is resisted by the reaction forces F1 and F2 generated by friction between the left tire 2L in the vehicle width direction and the right tire 2R in the vehicle width direction and the road surface, and a pressure P1 based on the centrifugal force G is generated on the suspension arm 100R on the right side. And the reaction force P2 that prevents it, on the left suspension arm 100L, the pulling force T1 based on the centrifugal force G and the reaction force T2 that prevent it are generated. In addition, when the vehicle is turning right, a force in the opposite direction to that in the above case acts. [0003] The suspension arm receives the above-mentioned force when the vehicle is cornering,...
