Trelleborg Industrial AVS is supplying Metalastik® Cushyfloat™ engine mounts to Volkswagen Marine for its new high output, lightweight TDI 225-6 six-cylinder turbo diesel.
The TDI 225-6 weighs only 325 kg. and is more than 100 kg. lighter than other marine diesels of comparable output.Based on the latest V-6 used in Audi A6, Audi A8 and VW Touareg cars, the compact three-litre engine employs a piezo-controlled, third-generation common rail injection system.Output is 225 hp at 4,200 rpm or 450 newton/metres of torque at 2,000, a profile ideally suited to accelerate the heavier powerboats on to the plane.It is initially offered in sterndrive configuration with Mercruiser Bravo 1 or Bravo 3 drives and also ZF gearboxes.
To meet the demands of this level of engine performance, Trelleborg Industrial AVS is supplying Cushyfloat™ mounts which are fitted either in a four point mounting system or two point when coupled to a Z-Drive gearbox.The Metalastik® Cushyfloat™ is a compact, low-profile mounting, combining three-way control of engine movement with relatively large deflection in the rubber element.A correctly mounted bearing provides maximum flexibility at right angles to the crankshaft, while the direction of maximum stiffness is in the fore and aft horizontal plane, the optimum arrangement for vibration damping and to accommodate propeller thrust.
Metalastik® Cushyfloat™ mounts are available in a range of sizes and three different rubber formulations to carry loads from 32 kg to 800 kg per unit and with natural frequencies down to 8 Hz.The metal parts are zinc-plated and the mounts incorporate bump and rebound control features to limit excessive movements under shock loads.All parts are designed to meet the highest standards of reliability, acoustic efficiency and shock protection in accordance with BS EN ISO 9001, Lloyds Register of Shipping, Det Norske Veritas and other authorities.
