Description
ную муфту 8 благодар подаче сигнала от устройства 6 через орган 9 управлени муфтой к исполнительному механизму последней. После блокировки дифференциала 7 нагрузка на полуоси 10 и 11 ведзщего моста перераспредел етс . В этом случае колесо, имеющее слабое сцепление с грунтом, передает меньшую часть крут щего момента от двигател , а другое колесо передает больщую его часть. По вл ющуюс разность крут щих моментов на колесах ведущего моста при заблокированном дифференциале измер ют с помощью датчика 12 и 13, установленных на полуос х 10 и И моста. Сигналы от этих датчиков подают к вычитающему устройству 14, где определ ют их разность и затем сопоставл ют ее с пороговой величиной, задаваемой пороговым устройством 15. Пока разность крут щих моментов на колесах моста больще пороговой величины , дифференциал удерживают заблокированным . Пороговую величину устанавливают из услови , что она быть больше крут щего момента на колесах ведущего моста при движении машины, например, по хорощей дороге с малым сопротивлением качению колес. После того, как улучщитс сцепление с грунтом буксовавщего колеса, последнее начнет передавать больший крут щий момент. При этом крут щий момент на другом колесе этого моста станет соответственно меньше, т. е. разность крут щих моментов на колесах моста уменьшитс . Когда эта разность станет меньще пороговой величины, дифференциал разблокируют, и тогда оба колеса мащиныclutch 8 due to the signal from the device 6 through the clutch control body 9 to the actuator of the latter. After locking the differential 7, the load on the half axes 10 and 11 of the superstructure is redistributed. In this case, a wheel with weak traction from the ground transfers a smaller part of the torque from the engine, while the other wheel transfers a large part of it. The occurrence of the torque difference on the wheels of the drive axle with the differential locked is measured using a sensor 12 and 13 mounted on a semi-axle x 10 and I axle. Signals from these sensors are fed to subtracter 14, where their difference is determined and then mapped to a threshold value set by threshold device 15. As long as the difference in torque between the wheels of the axle is more than the threshold, the differential is kept blocked. The threshold value is established from the condition that it be greater than the torque on the wheels of the drive axle when the machine is moving, for example, on a good road with low rolling resistance of the wheels. After the grip on the slip wheel improves, the latter will begin to transmit a greater torque. In this case, the torque on the other wheel of this axle will become correspondingly smaller, i.e. the difference in the torques on the axle wheels will decrease. When this difference becomes less than the threshold value, the differential is unblocked, and then both wheels of the machine
станут передавать одинаковый крут щий момент .will transmit the same torque.
При выезде колесной мащины с заблокированным дифференциалом на хорошую дорогуWhen leaving the wheel area with a locked differential on a good road
с малым сопротивлением качению колес крут щий момент на них снизитс в несколько раз. Соответственно резко уменьщитс и разность этих моментов, котора станет меньще пороговой величины, вследствие чего дифференциал будет разблокирован. Это предотвратит по вление паразитной мощности в ведущем мосту мащины при ее движении по дорогам с твердым покрытием.with low rolling resistance of the wheels, the torque on them will decrease several times. Accordingly, the difference between these moments, which will become less than the threshold value, is sharply reduced, as a result of which the differential will be unlocked. This will prevent the appearance of parasitic power in the drive axle of the machine when driving on paved roads.
