A wide range of drive shaft drive shaft is a high-speed, less support rotation, so it's dynamic balance is crucial.
The transmission shaft (DriveShaft) connects or assemble various accessories and movable or
rotating circular object fittings, usually made of alloy steel tubes with good light resistance and
torsion resistance. For the rear wheel driven car of the front engine, the rotation of the transmission
is transmitted to the shaft of the main reducer, and it can be connected by the universal joint for
several sections. It is a rotating body with high speed and less support, so its dynamic balance is very important. The general drive shaft should go into the balance test before leaving the factory and
adjust it on the balance machine.
Transmission characteristics:
In a front engine rear drive (or all wheel drive) car suspension vehicle, due to deformation in the
process of movement, drive axle main reducer input shaft and the transmission (or transfer) often
have the relative motion of the output shaft, in addition, to effectively avoid certain mechanism or
device (can not achieve linear transfer), there must be a device to realize the normal transmission of
power, so there is a universal joint drive. The universal joint drive must have the following
characteristics:
A, when the relative position of the two axes is connected to the expected range is changed, the
power can be transmitted reliably.
B, ensure that the two axes can run evenly. The additional load, vibration and noise produced by the
angle of the universal joint should be within the allowable range.
C, high transmission efficiency, long service life, simple structure, convenient manufacturing and
easy maintenance. On the car, because the output of a cross axle universal joint shaft relative to the
input shaft (a certain angle) is not constant rotation, so we must adopt double universal joint (or
joint) and the drive shaft is connected with the transmission of the two yokes are arranged in the
same plane, and the twenty thousand from the angle equal section. This is very important. The angle
of the cardan joint should be minimized in the design.
