The TT mounts are especially developed for the high powered / low weight, close coupled engine / gearbox combinations. The unique mounting design characteristics enables to transmit both Thrust and Torque forces whilst ensuring an excellent vibration isolation. The TT mounts have a linear stiffness over a wide load range varying from compression ( – ) to extension ( + ) necessary to maintain the optimum isolation properties of the Mass-Spring system formed by engine / gearbox and mounts. The close coupled gearbox reduces the engine rpm ’ s and as a consequence, magnifies the engine torque. The reaction torque is being transferred over the TT mounts to the foundation as additional compression or extension forces which requires the TT mounts unique linear (compression / extension ) stiffness to maintain the same high degree of isolation.
