На чертеже показана принципиальна The drawing shows the principal

двигатель 4 от гидротрансформатора 1. Одновременно т га 16 перемещает рычаг 12 управлени краном 11. Последний перекрывает нагнетающую гидролинию 10 насоса 5 подпитки, что вызывает по вление тормозного момента на валу насосного колеса 2, так как насос 5 подпитки работает в режиме гидсхема передачи.engine 4 from the torque converter 1. At the same time, the tractor 16 moves the crane control lever 12 simultaneously. The latter blocks the boost hydraulic line 10 of the feed pump 5, which causes a braking torque on the shaft of the impeller 2, as the feed pump 5 operates in the transmission flow diagram.

The value of the brake .1, including the pumping wheel 2, of the torque can be varied by the regulator mounted on the input shaft 3 connected to the engine 4 and the control system of the torque converter 1, which includes the feed pump 5 with the safety valve 6 and the actuator 7

Claims

rotate the safety valve 6. Formula of the invention

The transmission contains a torque converter, including a pumping wheel mounted on the input shaft connected to the engine, and the control system of the pumping wheel 2, connected by suction line 8 to tank 9, and pressure line O- to torque converter 1 through valve 11 with lever 12 controls. The transmission is equipped with a clutch clutch 13 with a driven member 14 on the input shaft 3, -fie- off switch 15 and a hard 16 connected to the control lever 12 and the pedal 15. A drain valve 18 is installed in the drainage line 17 of the torque converter 1.

The transmission works as follows.

When you press the pedal 15 clutch 13 is turned off, disconnecting

engine 4 from the torque converter 1. At the same time, the tractor 16 moves the crane control lever 12 simultaneously. The latter blocks the boost hydraulic line 10 of the feed pump 5, which causes a braking moment on the shaft of the impeller 2, as the charge feed pump 5 operates. The magnitude of the braking torque may vary

rotate the safety valve 6. Formula of the invention

circumferential brakes. The magnitude of the braking torque may vary

The transmission contains a torque converter, including a pumping wheel mounted on the input shaft connected to the engine, and a Lenin torque converter control system, including a feed pump with a safety valve and a pumping wheel drive, which is connected by suction hose to the hydraulic converter through a valve to the hydraulic converter through a valve with a hydraulic valve through a valve with a hydraulic valve to the hydraulic converter through a valve with a hydraulic pump. control, characterized in that, in order to increase the reliability, the transmission is equipped with a clutch with a driven element on the input shaft and with the off pedal, and Goy connected to the control lever: 7 and the pedal.
