Composition and principle of transfer case

1.       The transfer case is connected by two sets of gears respectively.       Its structure and principle are similar to that of a gearbox.       Cars equipped with the transfer case will have a special transmission lever, with 2H4Hn and 4L gears for 2 hours, and the power of the rear-wheel drive engine is connected directly through the gearbox to the rear axle through the drive shaft.

2.     Each shaft of the transfer case is supported by two tapered roller bearings, and the tightness of the bearings is adjusted by the corresponding adjustment pad.       When the front rear drive wheel has a different drive radius due to tire wear, it results in a loss of engine power and tire or drivetrain components.

3.       The main function of the transfer case through the separation and connection of the two sets of gears is to rationally distribute the power of the engine and transfer the power to the rear axle, or to the front and rear axle at the same time.       The structure and principle of achieving separation and connection 2 is similar to that of a gearbox with one and two axes.

4.       The transfer case is to lead out another output end on the gearbox, and transfer the power to the front axle output shaft through the silent chain.       When we pull the transfer box handle, power is connected to the front drive shaft.       The "low-speed four-wheel drive" gear of the transfer case is switched between two-wheel drive and four-wheel drive by another set of gear ratios in the transfer case.

5.       Transfer case is the distribution of engine power device.       It can output power to the rear axle or both.       The characteristic of a car equipped with a transfer case is that power is first transferred from the drive shaft to the transfer case.       The gearbox is then transferred to the front axle and the rear axle respectively by the transfer case, which can be switched between the rear wheel drive and the four-wheel drive.
