The drive device of the invention comprises a ready to fit unit or kit, for installing in a detachable manner on one side of a chassis of a motor vehicle. The unit comprises a flexible crawler looped round a drive wheel adapted to be mounted on a drive hub of the vehicle and round a tension wheel carried by a support frame, which comprises an internal part adapted to be secured in a detachable manner on the chassis remote from the drive shaft, an intermediate part adapted to carry the tension wheel and an external part carrying a bearing for the drive wheel. The invention is particularly of use for transforming vehicles with four drive wheels for crawler operation.

What is claimed is: 1. Drive device with for a vehicle comprising a chassis having a first side and a second side, at least one drive shaft operably attached to said chassis, a supporting hub disposed at one end of said at least one drive shaft, comprising: a ready to fit unit detachably installed
What is claimed is: 1. Drive device with for a vehicle comprising a chassis having a first side and a second side, at least one drive shaft operably attached to said chassis, a supporting hub disposed at one end of said at least one drive shaft, comprising: a ready to fit unit detachably installed on either said first side or said second side of said chassis, a support frame comprising an internal part removably attached to said chassis away from said at least one drive shaft, an intermediate part attached to said internal part, and an external part attached to intermediate part, a drive wheel removably mounted on said supporting hub of said drive shaft and having a bearing disposed on said external part, a tension wheel supported by said intermediate part, and, a flexible crawler wound around said drive wheel and said tension wheel. 2. Device according to claim 1, wherein said internal part of said support frame comprises an internal interface for securing on said vehicle chassis and an external interface adapted to secure said intermediate part of said support frame. 3. Device according to claim 1 wherein said intermediate part of said support frame comprises a tensioning and damping mechanism acting on a wheel support which supports said tension wheel. 4. Device according to claim 1, wherein said external part of said support frame comprises an arm having a first end detachably secured to said intermediate part and a second end for receiving a rolling bearing. 5. Device according to claim 4, wherein said first end of said arm is secured by bolts on said intermediate part. 6. Device according to claim 1, including at least one intermediate wheel carried by said support frame and arranged between said drive wheel and said tension wheel. 7. Device according to claim 6, including a bogie articulated on said support frame and carrying two said intermediate wheels. 8. Vehicle fitted with at least one device according to claim 1. 9. Vehicle according to claim 8, including two units, one of said units being mounted respectively on each side of said chassis and adapted to be driven by respective drive hubs connected to respective shafts of the same axle. 10. Drive device with a flexible crawler for a vehicle with a chassis and at least one drive shaft supporting a hub, said device comprising a ready to fit unit for installing in a detachable manner on one side of said chassis, said unit comprising a flexible crawler wound around a drive wheel adapted for mounting on said hub and around a tension wheel carried by a support frame, said support frame comprising an internal part adapted for securing in a detachable manner on said chassis remote from said drive shaft, an intermediate part adapted for carrying said tension wheel and an external part carrying a bearing for said drive wheel, wherein said intermediate part of said support frame comprises a tensioning and damping mechanism acting on a wheel support which supports said tension wheel, wherein said intermediate part of said support frame furthermore comprises a beam integral with said tension in and damping mechanism and a mechanism with a deformable connection interposed between said beam and said wheel support. 11. Device according to claim 10, wherein said mechanism with the deformable connection comprises two connecting rods, each said connecting rod being articulated to said beam and to said wheel support, to form a deformable quadrilateral.
