Multifunctional motor vehicles are equipped with one or more working mechanisms actuated by hydrostatic drive systems, which consume most of the power installed on such vehicles in which the primary mechanical energy is generated by an internal combustion engine, usually Diesel engine. Given the large number of daily running hours, (of multifunctional motor vehicles) the energy consumed by working mechanisms becomes important, the same goes for the expenses, and therefore it is required to be used with maximum eff...

Multipurpose vehicles are trucks that were implemented in order to achieve some different equipment related to road works such as snow removal, sweeping and spraying the streets, roadside mowing, trimming trees etc. Multipurpose vehicles have two operating modes. ? Regime for marching. Rapidly moving vehicles from one location to another. Torque at the drive wheels is small and the speed is high. ? Technological regime. The vehicle traveling at a low speed (max 8 km/h) imposed by technology of working multifunctio...
