Take Between Shaft Differential Thansfer Characteristic Analysis

In many of the drive shaft car, it is a thansfer transmission and between axles in the transmission chain of used to increase output, transmission torque, to enlarge the scope of change, and torque distribution to driving axle.

Thansfer types and characteristics

From the structure and function to see, can be divided into two kinds big. Thansfer

The first kind is gear type thansfer. General gear type thansfer drive, rear axle before two of output shaft in joints front drive meshing set for when the rigid connection. This kind of simple structure, the past in thansfer all kinds of full wheel drive car widely used, its shortcoming is no guarantee that the place before, rear wheel speed is equal, in the course of driving inevitably will generate the power cycle phenomenon. This will make the drive wheels load, a substantial increase in the tire and wear parts intensifies, fuel economy down. Therefore, should be in a separation of thansfer front axle drive device, in car through the gliding paragraph can engage front axle. In addition, general gear type thansfer assigned to the former, rear axle torque ratio between. So this will add to the adhesive condition good driving axle driving force, but may make the bridge for overload and damage. Therefore, currently USES this kind of thansfer car less

and less.

Another kind is to take between shaft differential thansfer. This kind of thansfer in before and after the output shaft is between a planetary gear shaft type between differential. It's just overcome the shortcomings, two of the output shaft can be different speed rotation, and according to certain proportion will be assigned to torque, before and after driving axle, already can make the front axle often in driving conditions, and can keep the wheel motor coordination, so don't need a pick up front axle drive from the device. In selecting a belt between shaft differential thansfer, try to make before, rear axle shaft torque distribution close to Hollywood, and to make RenYiQiao distribution of the maximum input torque not more than the bridge's allow input torque. In order to avoid a bridge in the wheels skid completely lost when driving force, this kind of thansfer needs to set between shaft differential locks, so that in a bridge in the wheel slippage will thansfer before and after the output shaft for an organic whole, improve the lock by sex.

Take between shaft differential thansfer characteristic analysis

Take axis of the differential between general set apart in thansfer differential planetary mechanism, can exercise decomposition and synthesis; And make thansfer compact structure, carrying capacity, stable, the noise is small, the life is long. The differential between shaft thansfer is essentially a two degrees of freedom differential linear, of which planet shelf to active parts, surface wheel and tooth lap is center follower, respectively with the before and after the output shaft drive
