Description

The invention relates to the transport engineering industry, to the transmission of transport vehicles, to the NTS (ground transportation systems), including towing vehicles of road trains, SDM (construction and road vehicles), tractors, special purpose ground vehicles, etc.

Transmission aggregates are known - gearboxes (KP) with step change of gear ratios, containing gears, shafts, bearings, gearshift devices used on domestic and foreign cars (Osepchugov V.V., Frumkin A.K. Car: Structural analysis, elements calculation. - M .: Engineering, 1989. - 304 p.).

These units are structurally complex and metal-intensive.

Closest to the proposed 24-speed manual gearbox (multi-stage gearbox) is the 16-speed manual gearbox according to RU patent No. 2350485 C1 (Bull. No. 9 of 03/27/2009).

The 16R8 all-planet gearbox according to RU patent No. 2350485 consists of a coaxial three-shaft 8-speed unit and a simple three-link PM (planetary gear), which provides three modes of operation: direct transmission, deceleration gear and reverse gear. 8 gears, three shifting clutches (one of them double) of the unit and three PM links (sun gear, epicyclic wheel and carrier with satellites) with two shifting clutches provide 16 forward gears and 8 reverse gears.

The disadvantages of the described transmission unit are the limitation of the operational and layout characteristics of the vehicle with an insufficient number of gears and a gearbox range (ratio of gear ratios of lower and higher gears), the input shaft design requires additional support at the end of the crankshaft, which eliminates the possibility of autonomous installation of the gearbox.

The problem to which the invention is directed, is to expand the operational and layout capabilities of the vehicle.

The problem is solved by increasing the number of gears and the range of the manual gearbox, as well as the location of the internal support of the input shaft in the tubular output shaft.

The achievement of the technical result is ensured by the fact that the coaxial all-planetary gearbox contains a three-shaft unit with four pairs of interlocked gears and a simple three-link planetary gear, the gears are mounted freely on the input and secondary shafts, two gear crowns with three-position switching clutches are fixed on these shafts two blocks of two gears are freely installed in the intermediate shaft, between the gear blocks and on the middle gears of the input shaft on the gear veins ah arranged protivopolozhnorazvernutye-off coupling halves interconnected shift fork, the secondary shaft coaxially located terpolymer simple planetary gear mechanism; the satellites located on the axles of the carrier are engaged with the sun gear, as well as with the epicyclic wheel, to the body of which a tubular output shaft with a gear rim is fixed, next to it there is a gear rim of the output shaft of the carrier, then there is an output shaft with a three-position gear rim a three-position switching clutch is installed, while a two-position gear ring with a two-position switching clutch is fixed at the output of the tubular secondary shaft, a gear ring is located next to this gear ring the input gear crown of the sun gear mounted on the shaft of this gear next to the gear rims of the tubular input shafts of the carrier and the epicyclic wheel housing, a two-position gear ring with a two-position stop carrier of the carrier and the epicyclic wheel is fixed on the housing wall; and a three-position gear ring of the output shaft is a gear output ring mounted on the shaft of the sun gear.
