Vehicle suspension control arm

Claim 2

In a control arm having a pair of spaced parallel wall portions extending longitudinally of said control arm, the combination comprising, means defining an aperture in each of said wall portions of said control arm, said apertures being identical in configuration and aligned on a transverse axis of said control arm, a sleeve having an internal configuration corresponding to the configuration of said aligned apertures and a length substantially equal to the distance between said wall portions of said control arm, said sleeve being disposed between said wall portions in register with each of said aligned apertures, and means on said control arm defining rigid flanges around at least a portion of the perimeter of each of said aligned apertures, each of said flanges extending inwardly into said sleeve in generally perpendicular relation to the corresponding one of said wall portions and engaging a corresponding portion of the internal surface of said sleeve thereby to secure said sleeve against bodily movement relative to said control arm longitudinally of the latter.

Claim 3

In a control arm having a pair of spaced parallel and transverse extending wall portions interconnected by a web portion coextensive with said wall portions, the combination comprising, means defining a circular aperture in each of said wall portions of said control arm, said apertures being of equal diameter and aligned on a longitudinal axis of said control arm, a cylindrical sleeve of length substantially equal to the distance between said wall portion, said sleeve having an internal diameter equaL to the diameter of said aligned apertures and a receptacle portion at each end thereof of larger inside diameter, said sleeve being disposed between said wall portions in register with said aligned apertures, and means on said control arm defining a flange around the circumference of each of said aligned apertures, each of said flanges extending inwardly into a corresponding one of said receptacle portions of said sleeve in generally perpendicular relation to the corresponding one of said wall portions and being of thickness generally equal to one half of the difference between the inside diameter of said sleeve and the inside diameter of said receptacle portions thereof so that said sleeve is rigidly secured to said control arm and said flanges define with said sleeve a substantially constant diameter transverse passage through said control arm.

Claim 4

In a control arm having a pair of spaced parallel and transverse extending wall portions interconnected by a web portion coextensive with said wall portions, the combination comprising, means defining a circular aperture in each of said wall portions of said control arm, said apertures being of equal diameter and aligned on a longitudinal axis of said control arm, a cylindrical sleeve of length substantially equal to the distance between said wall portion, said sleeve having an internal diameter equaL to the diameter of said aligned apertures and a receptacle portion at each end thereof of larger inside diameter, said sleeve being disposed between said wall portions in register with said aligned apertures, and means on said control arm defining a flange around the circumference of each of said aligned apertures, each of said flanges extending inwardly into a corresponding one of said receptacle portions of said sleeve in generally perpendicular relation to the corresponding one of said wall portions and being of thickness generally equal to one half of the difference between the inside diameter of said sleeve and the inside diameter of said receptacle portions thereof so that said sleeve is rigidly secured to said control arm and said flanges define with said sleeve a substantially constant diameter transverse passage through said control arm.

Claim 5

A control arm comprising, an elongated hollow tubular member square in cross section with four integral longitudinally extending sides, said four sides defining two pairs of a parallel spaced longitudinally extending wall portions, means on said tubular member defining a flanged circular aperture in each wall portion of one of said two pairs of wall portions, each of said flanged apertures being equal in diameter and aligned on a transverse axis of said tubular member adjacent one end thereof and said flanges extending inward in generally perpendicular relation to the corresponding one of said wall portions, a hollow cylindrical sleeve having an inner diameter generally equal to the diameter of said flanged apertures and a pair of cylindrical receptacle portions at opposite ends thereof each having an inner diameter exceeding the inner diameter of said sleeve by an amount equal to two times the thickness of said flanges around said apertures, said sleeve having a length substantially equal to the distance between said one pair of wall portions, and means disposing said sleeve between the wall portions of said one pair of wall portions in register with said apertures and with each of said flanges being closely received in a corresponding one of said receptacle portions of said sleeve so that the latter is rigidly secured to said tubular member and defines with said flanges a substantially constant diameter transverse passage through said tubular member.

Claim 6

A control arm comprising, an elongated hollow tubular member square in cross section with four integral longitudinally extending sides, said four sides defining two pairs of a parallel spaced longitudinally extending wall portions, means on said tubular member defining a flanged circular aperture in each wall portion of one of said two pairs of wall portions, each of said flanged apertures being equal in diameter and aligned on a transverse axis of said tubular member adjacent one end thereof and said flanges extending inward in generally perpendicular relation to the corresponding one of said wall portions, a hollow cylindrical sleeve having an inner diameter generally equal to the diameter of said flanged apertures and a pair of cylindrical receptacle portions at opposite ends thereof each having an inner diameter exceeding the inner diameter of said sleeve by an amount equal to two times the thickness of said flanges around said apertures, said sleeve having a length substantially equal to the distance between said one pair of wall portions, and means disposing said sleeve between the wall portions of said one pair of wall portions in register with said apertures and with each of said flanges being closely received in a corresponding one of said receptacle portions of said sleeve so that the latter is rigidly secured to said tubular member and defines with said flanges a substantially constant diameter transverse passage through said tubular member.
