Articulated tracked vehicle
The invention relates to an articulated tracked vehicle comprising a first vehicle unit and a second vehicle unit controllably connected by means of a control member, wherein the first vehicle unit comprises a combustion engine, wherein the combustion engine is arranged to drive a generator for electrical generation, wherein the generator is arranged to transfer power via power electronic means to at least one electric motor of at least one electric propulsion unit.
1. An articulated tracked vehicle comprising a first vehicle unit and a second vehicle unit controllably connected by means of a control member, wherein each vehicle unit consists of one electric motor for driving respective wheels of the vehicle unit via drive shafts for propulsion of the vehicle, which wheels drive respective tracks of each vehicle unit, wherein the first vehicle unit comprises a combustion engine, wherein the combustion engine is arranged to drive a generator for electric power generation, wherein the generator is arranged to transfer electric power via power electronics to said one electric motor of each vehicle unit, wherein propulsion of the vehicle is arranged to be effected only electrically, and wherein power transfer between said vehicle units is arranged to be effected only electrically.
2. An articulated tracked vehicle according to claim 1 , wherein said one electric motor of each vehicle unit is part of an electric propulsion unit that further comprises a transmission configuration arranged to transfer power for propulsion of the vehicle.
3. An articulated tracked vehicle according to claim 2 , wherein the transmission configuration comprises at least one planetary gearing.
4. An articulated tracked vehicle according to claim 1 , comprising two tracks per vehicle unit.
5. An articulated tracked vehicle according to claim 1 , comprising an energy storage unit arranged to supply energy to said power electronics.
