Spindle (automobile)

 In an automobile, the wheel spindle, sometimes simply called the spindle, is a part of the suspension system that carries the hub for the wheel and attaches to the upper and lower control arms.

Spindles are carried by steering knuckles or "uprights".[1] Although, the terms "steering knuckle" and "upright are sometimes used interchangeably with "spindle", they refer to different parts.[2]

DesignEdit

There are several considerations when designing a spindle. Loads and forces need to be considered. Vertical and horizontal forces greater than those due to 5 times the acceleration of gravity, that is, approximately 50 meters per second squared, are sometimes considered desirable.[citation needed]

Non-driven wheelEdit

The main forces on a non-driven wheel are braking and turning forces.

Driven wheelEdit

The forces on a driven wheel include forward and reverse propulsion as well as the braking and turning forces.
