ABSTRACT:
A fluid-filled elastic mount for flexibly supporting a vehicle propeller shaft to the vehicle body, having an elastic body interposed between an inner and an outer sleeve. The mount has a pressure-receiving chamber, and a generally arcuate void which extends axially of the sleeves and which is located opposite to the pressure-receiving chamber in the diametric direction of the sleeves. The mount further has a first and a second equilibrium chamber adjacent to the circumferential ends of the pressure-receiving chamber and are partially defined by a first and a second flexible diaphragm. The pressure-receiving chamber communicates with the first and second equilibrium chambers through differently tuned first and second orifice, respectively. An elastic stop is disposed within the pressure-receiving chamber for limiting the relative displacement of the inner and outer sleeves.
