Abstract:
1. An anti-separation device for use with an isolator that couples a steering input shaft having an axis and a steering gear connector, comprising: a first retaining plate perpendicular to the axis, and a second retaining plate perpendicular to the axis, the first and second retaining plates coupled to the steering gear connector and configured to displace with and torque with the steering gear connector, the first retaining plate and the second retaining plate each having at least one retaining hole through the first retaining plate and the second retaining plate, at least a portion of the first retaining plate and the second retaining plate being coplanar in a plane that is perpendicular to the axis; a cup-shaped member having a first surface that is perpendicular to the axis, and a second surface that is cylindrical and parallel with the axis, wherein the member is coupled to the input steering shaft and is configured to torque with the input steering shaft, wherein the member, the first retaining plate and the second retaining plate are configured to substantially enclose the isolator; a fisrt leg extending from the second surface in a direction parallel to the axis and received by the at least one retaining hole through the first retaining plate, and a second leg extending from the second surface in a direction parallel to the axis and received by the at least one retaining hole through the second retaining plate, wherein the first leg and the second leg are coupled to both the steering input shaft and the steering gear connector; wherein when the isolator fails and the steering input shaft displaces or rotates relative to the steering gear connector, the first retaining plate and the second retaining plate limits the relative displacement or rotation of the retaining formation and couples the steering input shaft to the steering gear connector; and the first retaining plate and the second retaining plate each have a semi-circular shape, and wherein the first retaining plate and the second retaining plate each have an overlapping portion and a coplanar portion, wherein the coplanar portion of the first retaining plate is coplanar with the coplanar portion of the second retaining plate.
