Steering Swivel: Description and Operation
Steering Swivel Member
The steering swivel member is the main component of the wheel bearing assembly and consists of a bearing housing with steering arm, mountings for
the MacPherson strut, ball joint and outer track-rod end. The steering arm is curved inwards and causes the front wheels to assume slightly different
angles when cornering so that the car will be easier to steer round bends.
The bearing is of double-row angular-contact type. It is pressed into the steering swivel member. The hub is pressed into the bearing. The brake disc is
mounted on the outside of the hub and the backplate is bolted to the steering swivel member.
When the steering wheel is turned the steering swivel member with wheel hub and wheel rotates about an imaginary line, the steering swivel axis,
which runs through the ball bearing in the upper spring cup and the steering swivel member's ball joint.
