Трансмисси гусеничной малпины работает следующим образомоTransmission tracked Malpina works as follows

В .пр молинейном движении гидрообъемна передача 12 имеет максимальную угловую скорость одного знака, причем кинематические параметры планетарного механизма 9 и приводов выбраны так, что звено 19 неподвижно. Это позвол ет путем одновременного включени двух муфт 17 и 18 обеспечить устойчивое пр молинейное движение гусеничной машины. Муфта 16, св зывающа звень 13 и 14 суммирующих планетарных р дов, включена, аIn the linear motion, the hydrovolume transmission 12 has a maximum angular velocity of one sign, with the kinematic parameters of the planetary mechanism 9 and the drives selected so that the link 19 is fixed. This makes it possible, by simultaneously connecting two sleeves 17 and 18, to provide a stable, straight-line movement of the tracked vehicle. Clutch 16, linking links 13 and 14 summing planetary rows, is included, and

тормоза 3 и 4 выключены.brakes 3 and 4 are off.

При повороте одна из муфт 17 или . 18 в. зависимости от направлени поворота -выключаетс , после чего начинаетмощности гидрообъемной переда й 12 отключаетс муфта 16 и включ етс один из тормозов 3 или 4 в зависимости от направлени поворота, при зтом гидрообъемна передача 12 работает только на забегающий борт гусеничной машины оWhen turning one of the clutches 17 or. 18th century depending on the direction of rotation, it is switched off, after which the hydrostatic gear 12 starts its power, the clutch 16 is disengaged and one of the brakes 3 or 4 is activated depending on the direction of the turn, while the hydrovolume gear 12 operates only on the running side of the tracked vehicle

При переходе от поворота к пр молинейному движению, управл гидрообъемной передачей 12, измен ют угло вую скорость звена 19 трехзвенного планетарного механизма 9 до нул , по ле чего включают муфты, выключенные при повороте, и выключают тормоз, включенный при повороте. Включение и выключение муфт происходит при непод вижных звень х, св зываемых -этими му тами, и практически при отсутствии крут щего момента.During the transition from rotation to linear motion, controlled by hydro-volumetric transmission 12, the angular velocity of link 19 of the three-link planetary mechanism 9 changes to zero, after which they turn on the clutches that are turned off during the turn and turn off the brake that is turned on. Couplings are switched on and off at fixed links connected by these clutches, and practically in the absence of torque.

Трансмисси позвол ет снизить потребл емую мощность гидрообъемной передачи за счет передачи мощности о гидрообъемной передачи на борт гусеничной машины, что позвол ет уменьшить вес и габариты, причем дл упра лени поворотом на малых радиусах ис пользованы .бортовые остановочные тор моза.The transmission allows to reduce the power consumption of the hydrostatic transmission by transferring the power of the hydrostatic transmission to the tracked vehicle, which reduces the weight and size, and the airborne stopping tori of the mosaics are used to control the rotation at small radii.
