Transfer case
Transfer box is used on vehicles greater high maneuverability with front and rear driving mos- Tami and serves to transmit torque to the leading bridges, as well as for switching on and off front driving axle. Depending on the assignment handout box can be performed with an additional step-down transfer or without it. Transfer case is usually set out installed behind the gearbox and connected to the gimbal shaft. In the simplest transfer case almost identical to PE- transfer shaft rear axle is constantly connected to the mechanism- mi drive and to turn on the front axle there is tooth clutch. With this inclusion, torque the drive wheels front and rear axles is determined in accordance with the forces of adhesion of the road surface with the wheels of the car. To prevent slippage the front steered wheels when turning on roads with improved surface, the front axle need must be disabled and enabled only in difficult road conditions. In a more complex dispensing cartons are used inter- axial differential, which allows you to spin the shafts drive the front and rear axles with different angular speeds, eliminating slippage of the front wheels relative to the road surface when turning, thereby allowing one to run loss of engine power due to its circulation in transmission and saves fuel. Additional reduction gearing in the transfer case the box gives you the opportunity to further increase traction force to the drive wheels of the vehicle. This scheme handout the box differs from the simplest to the presence of pairs of pole- Wren, increasing the gear ratio. Transfer box car with worth from: • Carter; • the drive shaft; • intermediate shaft; • driven shaft; • drive shaft front axle. Front axle activated by movement of the mobile gear intermediate shaft ago. With direct transmission gear drive shaft on the spline moves back and her teeth are engaged with internal teeth gear- Terni driven shaft. The inclusion of the downshift Pro- performed with moving a gear of the drive shaft forward until meshing with the gear of the intermediate shaft. The gearshift is placed on the side of the transfer accurate box and consists of two sliders and forks, which which are actuated by levers placed to CA Bina driver. Before you enable downshift you need to disable the front axle, otherwise the transmission is not off by a special device STV. The principle of operation of the switching mechanism of razdatok- Noah box is similar to the mechanism switch boxes gear. In the gearbox and transfer case use transmission oil, which can be summer and winter . Transmis- cost oil is extracted from the oil by settling, and it has a higher viscosity than engine oil. It the oil has a high ability to stick good to lubricated surfaces (oiliness). Level the oil boxes should be on the edge casting hole. |
