Abstract
Abstract An automotive vehicle rear axle includes longitudinally rearwardly extending control arms pivoted at their forward end on the body and carrying road wheels at their rearward end, a transverse beam connected to each control arm between the body pivot and wheel axis thereof, the connections permitting relative rotation between each control arm and the respective connected end of the transverse beam along an axis of the latter which extends obliquely to the control arm.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
155 words
Rear wheel suspension for automotive vehicles of the type including a pair of longitudinal control arms pivoted at their foward ends on the vehicle body and rotatably mounting adjacent their rearward ends the respective vehicle wheels, and a transverse member adapted for connection at each end thereof to a respective control arm intermediate the ends of the latter in a substantially rigid fashion in the vehicle end view whereby such member controls wheel camber, the improvement which comprises constructing said transverse member with straight end portions and a midportion offset longitudinally of the vehicle body from the transverse plane through the points of connection between said member and the control arms, the axis of each end portion of said member being oriented at said points of connection with the respective control arm at an oblique angle, and means connecting each end of said member with a respective control arm for relative rotation on said axes.
Claim 2
Dependent Claim
155 words
Rear wheel suspension for automotive vehicles of the type including a pair of longitudinal control arms pivoted at their foward ends on the vehicle body and rotatably mounting adjacent their rearward ends the respective vehicle wheels, and a transverse member adapted for connection at each end thereof to a respective control arm intermediate the ends of the latter in a substantially rigid fashion in the vehicle end view whereby such member controls wheel camber, the improvement which comprises constructing said transverse member with straight end portions and a midportion offset longitudinally of the vehicle body from the transverse plane through the points of connection between said member and the control arms, the axis of each end portion of said member being oriented at said points of connection with the respective control arm at an oblique angle, and means connecting each end of said member with a respective control arm for relative rotation on said axes.
Claim 3
Dependent Claim
164 words
Rear wheel suspension for automotive vehicles of the type including a pair of longitudinal control arms pivoted at their forward ends on the vehicle body and rotatably mounting adjacent their rearward ends the respective vehicle wheels, and a transverse member adapted for connection at each end thereof to a respective control arm intermediate the ends of the latter each said connection in a substantially rigid fashion in the vehicle end view whereby such member controls wheel camber, the improvement which comprises constructing said transverse member with straight end portions and a midportion offset rearwardly of the vehicle body from the transverse plane through the points of connection between said member and the control arms, and the axis of each end portion of said member being oriented at said points of connection with the respective control arm at an oblique angle, and means including torsionally elastic bushings connecting each end of said member with a respective control arm for controlled relative rotation on said axes.
Claim 4
Dependent Claim
164 words
Rear wheel suspension for automotive vehicles of the type including a pair of longitudinal control arms pivoted at their forward ends on the vehicle body and rotatably mounting adjacent their rearward ends the respective vehicle wheels, and a transverse member adapted for connection at each end thereof to a respective control arm intermediate the ends of the latter each said connection in a substantially rigid fashion in the vehicle end view whereby such member controls wheel camber, the improvement which comprises constructing said transverse member with straight end portions and a midportion offset rearwardly of the vehicle body from the transverse plane through the points of connection between said member and the control arms, and the axis of each end portion of said member being oriented at said points of connection with the respective control arm at an oblique angle, and means including torsionally elastic bushings connecting each end of said member with a respective control arm for controlled relative rotation on said axes.
Claim 5
Dependent Claim
