14-STEP NON-AXIAL POWER-PLANETARY GEAR BOX Russian patent published in 2010 - IPC F16H37/08 

FIELD: machine building.

SUBSTANCE: fourteen-step non-axial power-planetary gear box consists of two-shaft non-axial reducer in supports of which there are axially installed input shaft and additional shaft. Parallel to them there is mounted a secondary shaft and an output shaft of the carrier of the three-link planetary mechanism. Two pinions are united into a block on the secondary shaft and engage a pinion of the input shaft and a drive pinion of the additional shaft. 3-position shift collar is installed between these pinions on a rim of the input shaft. Two pinions of forward running are arranged on the additional shaft; they engage pinions freely mounted on the secondary shaft. The drive pinion of back running engages a driven gear of back running of the secondary shaft via the additional pinion. The first 3-position shift collar of the secondary shaft is located on the first rim next to the pinion block. The second 3-position shift collar of the secondary shaft is located on the second rim next to the driven gear of back running. The rim of the output shaft of the carrier is 2-positioned; while the rim of the output shaft of the aggregate is 3-positioned. 3-position shift collar on this rim has three internal rims; also a rim of internal and external engagement is mounted on a slider of this shift collar, and its external engagement is coupled with 3-position rim of the aggregate case.

EFFECT: expanded operational functionality of process vehicles due to extended range and gear ratio of back and forward running.
