Designation:

ESM 350

Info
Manufacturer: RENK France S.A.S.  
Product type: Transmission & Drives  
Name: Transmission  

The ESM350 is a high performance transmission developed and volume manufactured by SESM for retrofits of T-72/T-90 type vehicles. With a power range from 600 to 850kW, it features eight speeds forward and 3 speeds reverse, an infinitely superimposed steering system and a high performance braking system. It is suitable for T-72/T-90 new series as well as for upgrading program. The integration process is very easy and preserves the original silhouette of the vehicle.

Technical characteristics:

  • Powerpack design especially for T-72 vehicles and derivates

  • Manual and fully automatic power shifting

  • Mechanical emergency gear shift system

  • Electronically controlled automatic start-up clutch

  • Infinitely variable hydrostatic superimposed steering system

  • Pivot turn and neutral turn on the spot at infinitely variable speed

  • Integrated multi-disks service and parking brake

  • Power-take-off for T-72 genuine power units like dynamo-starter, air compressor etc..

  • Power-take-off for fan drive with fully digital speed control and cut off

  • Engine can started by towing the vehicle


Superior mobility by the addition of an automatic powershift transmission and increased engine power (up to 1150 hp):

  • Top speed of 70km/h and 23 km/h reverse, start-up on 60% slope for a 50 tons vehicle

  • Increased vehicle speeds even with inex-perienced drivers, especially in difficult terrain

  • More intelligent use of engine power and elimination of driver error thanks to the electronic transmission control

  • Increased operating range, reduced fuel consumption, reduced heat emissions

and cooling needs

Enhanced operation in hot climatic conditions due to the high performance cooling system:

  • Drastically increa sed cooling air flow compared to conventional design

  • Automatically and permanently optimized fan speed adapted to cooling needs to minimize power losses

  • Increased engine lifetime due to a more stable engine coolant temperature

  • Availability of full engine power even in extreme hot conditions

  • Option to switch off the cooling fans for special operations such as fording
