Strut mounts make the vital connection between the suspension strut and the vehicle’s subframe. They serve multiple important purposes such as isolating road noise and vibrations, following suspension movements and maintaining correct wheel alignment. In MacPherson suspensions, they’re even a steering pivot!
Basically, a strut mount is like a silent block: they are a metal-to-rubber bonded bushing, mounted on the top of the damper at one side and to the subframe at the other. They act as a rubber cushion, dampening road noise and vibrations.
They’re not just any cushion though. With every in- and outward movement of the suspension, the camber and strut angle changes (following the lower ball joint movement). The strut mount allows this change in angle and therefore plays a crucial role in the wheel alignment!
As mentioned, the strut mounts in MacPherson suspensions work even harder:
They act as a steering pivot, as the complete strut rotates along with every steering movement. Therefore, they contain a bearing allowing steering rotations between the strut and the subframe.
Along with this, they also take on (horizontal) bending forces which occur when the suspension is working. While the upper track control arms take over this task with multi-link and double wishbone suspensions, the MacPherson strut mounts have to do it all!
WHY SIDEM STRUT MOUNTS?
For your safety, we provide strong strut mounts with superior rubber and excellent metal-to-rubber bonding. A lot of forces constantly act on strut mounts, ours are up for the task!
Stiffness, flexibility and Shore hardness are vital properties. Our strut mounts are tested in every possible way to ensure your driving comfort, stability and correct wheel alignment.
We don’t use just any bearing in our strut mounts. To allow smooth steering movements, we use thrust bearings which can handle load and impacts. This way, we ensure durable strut mounts!
CONSTRUCTION OF SIDEM STRUT MOUNTS.
Strut mounts in car suspension systems can fail due to a combination of factors that lead to wear over time. One primary cause is constant exposure to road impacts and vibrations, which gradually degrades the rubber components within the mount. Over time, this can result in cracking, splitting, or flattening of the rubber, reducing its ability to absorb shocks and dampen vibrations.
Additionally, strut mounts can fail due to rust and corrosion, particularly in areas where road salt is used during winter. This corrosion can weaken the metal components of the mount, compromising its structural integrity. Poor installation or using inferior-quality materials can also accelerate wear, leading to noise, misalignment, and reduced ride comfort. Regular inspections and replacing strut mounts with high-quality, durable components are essential to maintaining suspension performance and vehicle safety.
