Vehicle manufacturers fit their vehicles with insulators and vibration countermeasures to reduce noise, vibration and harshness. The traditional and most commonly used form is the rubber mount. This is available in numerous shapes and sizes from a simple cotton real shape to a very complex rubber and metal formation. Stiffness is regulated within the properties of the elastomeric material used, and the direction of movement is determined by the fixed links within the design of the mount.
As an engine mount ensures smooth, stable and quiet driving, they carry the weight of the engine and absorb vibrations. It is essential to use high-quality mountings for such a safety critical component on your vehicle, to ensure maximum control and safe driving.
The more dynamic hydraulic mount combines the acoustic isolation functions of a conventional rubber engine mount, but with a balanced damping performance. Hydraulic engine mounts can adapt their characteristics depending on the induced load. The viscous liquid in the hydraulic mount acts as a damper to ensure optimum insulation.
An electronically controlled engine mount meets dampening requirements, but with more control. The switching function causes the air suspension in the mount to be utilised in the neutral position, providing soft suspension when at idle or low rpm. Then, when the vehicle is being driven, the mount switches to hydraulic suspension and provides a firmer suspension between the engine and the vehicle’s body.
In time all engine mountings have the potential to fail or wear, reducing their dampening countermeasures, which then causes discomfort for the driver. Rubber in the mount can crack over time, and as the mounting perishes, the engine may shift slightly, which can cause excessive vibration. In the case of a hydraulic mounting, if wear and tear take place, it can cause the fluid to leak. It is important to check the mounting regularly and replace if there are any signs of wear.
