ABSTRACT:
An independent strut suspension utilizes upright twin spindles and a spindle cap linked to the spindles that translates vertically along the spindles as the suspension moves over uneven terrain. An upright strut shaft is mounted in a strut journal for axial and rotational movement with respect to the journal. A steering arm is connected for rotation about the strut shaft axis, and the strut shaft moves axially with respect to the steering arm as the frame moves over the uneven terrain. The upright spindles connect the steering arm and the upper mount, and a spring is supported between the upper end of the strut shaft and the upper mount and provides cushioning for the wheel support as the strut shaft moves axially in the journal.
