Steyr heavy duty truck series according to different driving forms, choose different types of transmission shaft. Generally speaking, 4 x 2 drive form only a main transmission shaft of automobile. 6 x 4 drive in the form of cars have intermediate shaft, a main drive shaft and drive shaft, rear axle. 6 x 6 drive forms of motor not only have the intermediate shaft, a main drive shaft and drive shaft, rear axle, and drive front axle drive shaft. Intermediate shaft from the vehicle in the long axis of the general with the drive shaft intermediate bearing. It is composed of a supporting frame, bearing and a rubber support.

The drive shaft is composed of a shaft tube, a telescopic sleeve and a universal joint. Telescopic sleeve can automatically adjust the transmission and changes the distance between driving bridge. Universal joint is a guaranteed transmission converter output shaft and the input shaft driving bridge two axis angle, and realize the constant velocity transmission axes. General universal joint cross, cross bearing and a flange fork. Driving shaft universal joint Steyr heavy-duty vehicles using a roller cross shaft bearing, with short and thick cross shaft, can transfer large torque. Butterfly spring is arranged on the end face of the bearing, to press roller. End of cross axis enhanced nylon washer with a spiral groove, can prevent large angle or large torque of power transfer sintering.

The traditional structure of the transmission shaft telescopic sleeve is the spline sleeve and flange fork welded together, the spline shaft is welded on the transmission shaft tube. While the drive shaft GWB company changed the traditional structure, the spline sleeve and the propeller shaft tube are welded into a whole, the spline shaft and the flange yoke made of one. And the rectangular spline is changed into a large pressure angle involute teeth spline short, such not only increase the strength and easy extrusion, meet the needs of a large torque condition. On the surface of expansion sleeve and a splined shaft teeth, the whole coated with a layer of nylon, not only increases the wear resistance and self lubrication, but also reduce the damage of impact load on the transmission shaft, improve the buffering ability

This type of transmission shaft in the flange splined shaft is added with a tube shaped sealing protective sleeve, two polyurethane rubber oil seal is arranged in the protective sleeve end, make the factory a completely sealed space formed a telescopic sleeve, the flexible spline shaft from erosion of external dust, not only can prevent dust and rust. Therefore, in the assembly on the spline shaft and sleeve disposable grease, it can fully meet the use requirements, do not need to install the nozzle lubrication, reduce maintenance content.

The drive shaft is a rotating body of a high speed and less support, so its dynamic balance is crucial. The general transmission shaft in the factory have to dynamic balance test, and proposes some adjustment on the balancing machine. Therefore, a set of drive shaft is accessory factory, in use should pay special attention to.
