Here are the structural characteristics of drive shafts shared by Drive Shaft
Suppliers, please feel free to contact us if you need

The drive shaft is a high speed, less supported rotating body, so its dynamic
balance is crucial. Generally the driveshaft is dynamically balanced before it
leaves the factory and is adjusted on a balancing machine. For a front engine
rear wheel drive car is the shaft that transmits the rotation of the
transmission to the main gearbox, it can be several sections, and the sections
can be connected to each other by universal joints.

Drive Shaft

Drive Shaft

The drive shaft is composed of a shaft tube, a telescopic sleeve and a
universal joint. The drive shaft is connected or assembled with various
accessories, and the circular object accessories that can be moved or rotated
are generally made of light and good torsional resistance alloy steel tubes.
For a front-engine, rear-wheel-drive car, it is the shaft that transmits the
rotation of the transmission to the main gearbox, which can be several
sections connected by universal joints. It is a high-revving, less-supported
rotating body, so its dynamic balance is critical. Generally the transmission
shaft is dynamically balanced before it leaves the factory and is adjusted on
a balancing machine.

Structural Features
Steyr series heavy-duty trucks choose different types of Drive Shafts
according to the different driving forms. Generally speaking, there is only
one main drive shaft in 4×2 drive form. 6×4 drive form has intermediate
drive shaft, main drive shaft and middle and rear axle drive shaft. 6×6 drive
form has not only intermediate drive shaft, main drive shaft and middle and
rear axle drive shaft, but also front axle drive shaft. In long wheelbase
vehicles, the intermediate drive shaft is generally equipped with a drive
shaft intermediate support. It is composed of a support frame, bearings and
rubber bearings.

The driveshaft is composed of a shaft tube, telescopic sleeve and universal
joint. The telescopic sleeve can automatically adjust the distance between the
transmission and the drive axle changes. Universal joint is to ensure that the
transmission output shaft and the drive axle transmission axis of the two axis
line angle change, and to achieve the two axes of equal angular speed
transmission. General universal joint cross shaft, cross bearing and flange
fork and other components. The drive shaft universal joint used in the Steyr
series of heavy vehicles uses a roller cross shaft bearing, with a short and
thick cross shaft, can transmit a large distance. Butterfly spring is provided
at the end of the bearing to compress the roller. The end face of the cross
shaft has a reinforced nylon spacer with spiral grooves to prevent sintering
when transmitting power at large angles or large distances.

The conventional structure of the drive shaft expansion sleeve is a spline
sleeve welded to the flange fork, and the spline shaft is welded to the drive
shaft tube. GWB's drive shaft is a change from the traditional structure, the
spline sleeve and the drive shaft tube are welded together, and the spline
shaft and the flange fork are made into one. And the rectangular tooth spline
is changed into a large pressure angle involute short tooth spline, which not
only increases the strength but also facilitates the extrusion molding to meet
the needs of large torque working conditions. In the expansion sleeve and
spline shaft teeth surface, the overall coating of a layer of nylon material,
not only to increase the wear resistance and self-lubricating, and reduce the
impact load on the drive shaft damage, to improve the cushioning capacity.

This type of drive shaft outside the flange spline shaft added a tube seal
protection sleeve, in the protective sleeve end set two polyurethane rubber
oil seal, so that the expansion sleeve inside the plant to form a completely
sealed space, so that the expansion spline shaft from the erosion of external
sand and dust, not only dustproof and rust-proof. Therefore, when assembling
the spline shaft and sleeve, a one-time application of grease can fully meet
the requirements of use, no need to install oil nozzle lubrication, reducing
the content of maintenance.

Drive shaft is a high speed, less supported rotating body, the prisoner of its
dynamic balance is essential. General drive shaft in the factory before the
dynamic balance test, and in the balance machine for adjustment. Therefore, a
set of drive shaft is a matching factory, in use should pay special attention.
