Embodiment Construction

[0020] 1-5 illustrate the control arm assembly 10 operably engaging the steering knuckle 50 . The control arm assembly includes a control arm 20 , a first joint 30 and a second joint 40 . As is well known in the art, the control arm 20 has three joints, and the joints 30 and 40 of the control arm assembly 10 are adapted to be pivotally connected to the vehicle chassis portions 14 and 16 and / or other vehicle suspension components, A third point for rotational connection includes an end fitting 60 that engages the knuckle 50 in a ball joint fashion to connect to the vehicle wheels 18 and / or other vehicle suspension or steering elements.

[0021] The control arm 20 has a tubular steel body 62 with a joint 30 at a first end and an end fitting 60 at an opposite distal end. A link 40 is attached to the control arm 20 intermediate the first end and the opposite distal end. The joint 30 defines the axis of rotation of the control arm 20 . Joint 40 also defines an axis of rotation t...

Abstract

An assembly including a control arm and a steering knuckle, one of the control arm and the steering knuckle having a first end with a ball, the other of the control arm and the steering knuckle having a socket that includes a bearing structure formed so as to surround a portion of the ball to securely fasten the ball to the socket. The control arm has a bayonette configuration to receive a first node and a second node is cast directly onto the control arm.

Description

technical field [0001] The invention relates to a coupling assembly. This application explains embodiments of the invention, including embodiments related to automotive linkage devices, such as control arm / steering knuckle assemblies for motor vehicles. Background technique [0002] Control arms are used in motor vehicles to help support and control the various wheels of the motor vehicle. Typically, a control arm can be found connected between the frame and the wheel assembly of a motor vehicle, in particular between the frame and the steering knuckle. The construction of control arms in general is particularly complex for a number of reasons, such as the number and nature of the connections between the control arms and other vehicle components, as well as the performance requirements and stresses exerted on the control arms. [0003] Control arms have been formed by joining together a pair of stamped steel parts or by the hydroforming method disclosed in WO 03 / 101767 ent...
