Drive for a tracked vehicle or a vehicle with wheel based steering

摘要

The drive has an electrical machine for dissipating electrical energy, and a power electronics (26) for supplying electrical energy, where the power electronics is cooled by cooling fluid in a boiling cooling method. A fluid- or air heat exchanger or condensator (25) is provided for heat-exchange and condensation of steam arising during the cooling process and is cooled by ambient air of a vehicle (27). The housing of the electronics and the heat exchanger are connected with each other, such that pressures in the housing and the exchanger have a different level.
