What is?
also called differential between the central axle differential. Mounted on the intermediate shaft of the four-wheel type, it is used to adjust the speed of the front and rear wheels of the vehicle.

open center differential
the general structure symmetrical bevel gear, the planetary gear set which is not provided with any locking device, if one wheel slips, the remaining three wheels can not get the power, the influence of the vehicle turnaround .
Multi-disc clutch differentials
Multi-disc clutch differentials depend on wet multi-plate clutch are differential torque. This system is often used as a center differential timely four-wheel drive system use. There are two sets of friction disks therein, a set of driving disc, a driven plate group. Driving disc connected to the front axle, the rear axle is connected with the driven disc, the two friction disc binding and separation systems rely on electronic control. The advantage is a fast response, it may be an instant binding. The disadvantage can only transfer 50 percent power to the rear wheel easy to overheating, high load operation.
differential viscous coupling
In the all-wheel drive automobile wheel drive-based , usually traveling wheel drive mode. The driver operates the biggest feature is not required, the power can be automatically assigned to the rear axle as desired. The disadvantage is slow response, low torque distribution ratio, it could lead to failure due to overheating during high load operation.
Torsen differential
Torsen differential is a planetary worm gear structure, it works is purely mechanical, electronic system without any intervention. Torque distribution before and after its broader scope, the instant torque distribution ratio in accordance with road conditions before and after the adjustment. The disadvantage is that no two drive state, limited slip limited capacity. Principle is to use unidirectional transmission worm, both motion only from the worm to the worm wheel is transmitted, self-locking characteristics occur instead, the power can be smoothly assigned to front and rear output shafts through the planetary gear, thereby driving the front and rear axle. Dynamic characteristics of the worm gear transmission is just the opposite, it automatically with the power distributing planetary gears ordinary open differential to the output shaft side by a large resistance.
