Hydraulic Mount

AMC-MECANOCAUCHO® hydro mounts combine a spring and a hydraulic damper in a single compact unit that allows tuning of the spring and damper independently.

This provides flexibility in matching the dynamic characteristics of the isolator to the requirements of the application . The internal design of the mount is a new system that bonds the metal parts to the rubber effectively to eliminate leakage of the damping fluid when the mount is subjected to high magnitude shock inputs. For good isolation , low damping is required . For motion control high damping is required .

TECHNICAL CHARACTERISTICS

The AMC-MECANOCAUCHO® Hydraulic mounts have an interlocking metal component that provides fail-safe protection for mobile applications. This device limits excessive vertical movement when the mountings are subjected to shocks inputs.
The metal parts are suitably thick and robust to withstand Off Road vehicle application shock inputs and also have an outdoor anti-corrosive treatment fully compliant with RoHs

APPLICATIONS

The AMC-MECANOCAUCHO® Hydraulic mounts have been primarily designed as engine and operator cab isolator mounts in vehicular off highway and agricultural applications.

It is particularly interesting for those engines that operate on a variable rotating speed that must regularly pass the natural frequency of the system during its normal running. Examples of this may be engines of 1,2,3 or 4 cylinders used on construction or agricultural equipment.

It is also interesting for cabins where vibration isolation is for operator comfort purposes but also can provide stability when the cabin is submitted to transient shocks.

OPERATION AND ASSEMBLY

A hook wrench should be used in the slots to avoid the rotation movement of the rubber.

ELASTICAL PROPERTIES

ADVANTAGES

AMC Hydraulic Mounts accomodate these requirements as the fluid cavity is divided into two chambers with a specific orifice between them so that motion of the elastomeric element causes fluid to flow from one chamber to the other thus dissipating energy and creating damping in the system . These mounts are particularly suitable for installations requiring good vibration isolation but still require motion control under transient shock inputs , or when operating close to the isolation systems resonant frequency

For good isolation, low damping is required. For motion control, high dampening is required. The Mecanocaucho® hydraulic mounts accommodate these conflicting requirements. The fluid cavity is divided into two chambers with an orifice in between.
