FIELD: mechanical engineering.
SUBSTANCE: invention relates to automotive industry, to transport machines transmission. Use: vehicles – front-wheel-drive cars and light trucks, compact tractors, etc. Summary of the invention: for the unification of the gearbox part, in the gearbox with two clutches, with the change of the location on the shafts of some pairs of gears of even and odd gears, on the outer input shaft gears of even gears are installed, on the inner input shaft gears of odd gears are installed, and the driven gears of the first gear and/or the second gear or reverse gear are installed on one driven shaft. In this case, the gear unit part of the received gearbox is maximally unified with the gearbox part of the basic gearbox. And also the method allows to obtain common nodes and parts of the base and automated control gear with less metal capacity, which provides a reduction in the cost of production of the gearbox and the operation of its carrier car. In the basic gearbox and its modifications, it is possible to change the number of gears and/or the range of gear ratios without changing the total number of clutches. Allows to increase the number of modifications, including automated ones, with unified reducer parts.
EFFECT: technical result: possibility of obtaining its automated modification based on the base box with manual gear shifting.
