Struts are a major structural component of a cars chassis and suspension system. They are responsible for supporting the weight of the vehicle while also absorbing surface impacts and ensuring a smooth ride. Struts perform two main jobs:
-
Damping Function: Struts perform a damping function like shock absorbers. Internally, a strut is like a shock absorber, with a piston attached to the end of the piston rod that works against hydraulic fluid to control spring and suspension movement. The valving generates resistance to forces created by the up and down motion of the suspension.
-
Structural Support: Unlike shock absorbers, struts provide structural support for the vehicle suspension, support the spring, and hold the tire in an aligned position. Additionally, they bear much of the side load placed on the vehicles suspension. As a result, struts affect ride comfort and handling as well as vehicle control, braking, steering, wheel alignment, and wear on other suspension parts.
In summary, struts are an essential part of a cars suspension system that provide both damping function and structural support. They help to stabilize the vehicles movements, enhance control when turning, braking, accelerating, or encountering uneven road surfaces, and keep the tires in contact with the pavement.
