The present invention relates to an arrangement (A) of a drive wheel (DW) for an endless track (E) of a tracked vehicle (V). The drive wheel (DW) comprises a hub member (H) and a drive sprocket member (S, S) attached to the hub member (H). Said drive sprocket member (S, S) comprises a ring shaped drive sprocket () having a set of teeth () arranged around the circumference of said drive sprocket (). Said drive sprocket () is configured to engage with said endless track (E). Said drive sprocket member (S, S) further comprises a support member () for said drive sprocket (). Said drive sprocket () is divided into at least two arc shaped drive sprocket parts (A,B). Each drive sprocket part (A,B), in a non engaged state of a drive sprocket part with respect to said endless track, is configured to be exchangeable. Said arrangement (A) comprises a guiding configuration (G, G) comprising a first guiding member (G) circumferentially distributed around the support member () and a second guiding member (G) circumferentially distributed around the respective drive sprocket part (A,B) for facilitating reassembling the drive sprocket (). The present invention also relates to a tracked vehicle.

Arrangement of a drive wheel for an endless track of a tracked vehicle

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 comprises two tracks driven by drive wheels, wherein the first vehicle unit comprises a mechanical propulsion unit with a combustion engine for driving the drive wheels of the first vehicle unit and the second vehicle unit consists of one electric propulsion unit for driving the drive wheels of the second vehicle unit, 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 the electric propulsion unit of the second vehicle unit, wherein power transfer between said vehicle units is arranged to be effected only electrically.

Articulated tracked vehicle

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 comprises two driven tracks driven by drive wheels and has one electric motor per track for driving respective drive wheel via drive shafts for propulsion of the vehicle, 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 the electric motors 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.

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.
