TECHNICAL FIELD

This disclosure relates to a suspension system for a vehicle, such as a land vehicle like a truck.

BACKGROUND

A suspension system is disclosed in U.S. Patent Publication No. 2017/0320522.

SUMMARY

In at least one embodiment a suspension system is provided. The suspension system may include a knuckle carrier, a control arm, and a pivot mechanism. The knuckle carrier may have a hole. The control arm may be pivotally mounted to the knuckle carrier. The pivot mechanism may be disposed in the hole and may pivotally couple the control arm to the knuckle carrier. The pivot mechanism may include a pin, a first bearing assembly, and a preload nut. The pin may have a shoulder and a threaded portion. The first bearing assembly may receive the pin and may engage the shoulder. The preload nut may have a threaded region that mates with the threaded portion. Tightening the preload nut may exert a preload force on the first bearing assembly.

In at least one embodiment a suspension system is provided. The suspension system may include a knuckle carrier, a steering knuckle, an upper control arm, and a platform. The knuckle carrier may have a mounting stem. The steering knuckle may be pivotally mounted to the knuckle carrier along an axis of rotation. The upper control arm may be pivotally mounted to the knuckle carrier along a first control arm axis. The platform may be fixedly disposed on the mounting stem and may be located above the upper control arm. The platform may support an air spring and may have an arm that is coupled to a stabilizer bar subassembly.
