摘要

P a. improvements to the mechanisms of transmission, in particular for a tracked vehicles. / p & & p & b. the transmission mechanism comprises a transmission shaft mounted to rotate in a support in order to rotate about an axis, an outlet sprocket wheel carried by a first support so as to rotate about the axis of said shaft and a gear in order to cause said support on the basis of the shaft, including a first planet wheel rotating with the shaft around said axis, a certain number of the first planet gears driven by the sun gear, an external ring gear which is fixed coaxially to said shaft and which meshes with said first planet gears, a second planet wheel and a certain number of second planet gears rotatably mounted on the first support and meshing with said outer ring and with the second planetary gear, characterized in that it comprises means for mounting in rotation the second planet wheel on the said first support, coaxially to said shaft. / p & & p & c. in particular, the invention concerns improvements made to the assembly of certain components of the differential speed reducers of these mechanisms of transmission. / p
