Anti vibration mounts
HYDRAULIC CONE MOUNTS
The AMC-MECANOCAUCHO HYDRAULIC CONE MOUNT is a combination of a spring component and a hydraulic shock absorber in the shape of a cone. With this both components can be tuned to each other. For good vibration insulation you need a low dampening coefficient but for movement control you need a high dampening coefficient. The AMC MECANOCAUCHO HYDRAULIC CONE MOUNTS combine these two completely different requirements in one single bearing.
This gives you the opportunity to adapt the dynamic properties of the insulator to the individual requirements of the application.
Our vibration dampeners do this by the hydraulic fluid flowing from one chamber to the next as a result of the movement of the rubber component. An energetic dissipation results from this process.
Technical characteristics
AMC MECANOCAUCHO® hydraulic shock absorbers have an advanced breakaway device inside the bearing that prevents tensile forces on the elastomer by limiting its upward vibration stoke. The newly-developed internal structure of the vibration dampener consists of a metal part system. The elastomer is vulcanised to the whole of this. This prevents a loss of hydraulic fluid should the vibration dampener be subject to great dynamic overloads.
The thickness of the metal parts ensures that the dampener is strong enough for mobile applications. The metal parts are treated with a resistant corrosion protection for outdoor use.
TECHNICAL ADVICE FOR FOPS ROPS APPROVAL
AMC-MECANOCAUCHO's technical department will be pleased to offer you advice on correct installation procedures to achieve FOPS/ROPS tests approvals.

Applications
The AMC-MECANOCAUCHO HYDRAULIC CONE MOUNT is predominantly designed to insulate the vibration in engines and cabs in off-road vehicles (construction, agricultural and local authority vehicles). The HYDRAULIC CONE MOUNT has the necessary resilience to achieve a high level of decoupling. However, it also has the necessary stability for these applications in the event of impacts which thus prevents the vehicles from rocking. This ensures a high level of comfort as well as an immediate working and driving experience.
Another advantage becomes apparent with variable speed applications which are within the resonance frequency range in normal operation. This resonance is significantly reduced with the HYDRAULIC CONE MOUNT.
