Drive shaft equipment is an indispensable part of a car, just like human beings can’t live without arms, a car drive shaft is composed of a shaft tube, a telescopic sleeve and a universal joint. The telescopic sleeve can automatically adjust the distance between the transmission and the drive axle.



This type of drive shaft adds a tube-shaped sealing protective sleeve outside the flange spline shaft. Two polyurethane rubber oil seals are set at the end of the protective sleeve to form a completely sealed space in the factory to make the telescopic spline The shaft is not corroded by external sand and dust, not only dustproof but also rustproof. Therefore, when assembling, apply grease to the spline shaft and the sleeve at one time, which can fully meet the requirements of use, and there is no need to install a grease nipple for lubrication, reducing maintenance content.


The drive shaft is a rotating body with high speed and less support, so its dynamic balance is very important. Generally, the drive shaft must undergo a dynamic balance test before leaving the factory and adjusted on a balance machine. Therefore, a set of drive shafts are delivered as a complete set, so special attention should be paid during use.


Cars choose different types of drive shafts according to different drive forms. Generally speaking, a 4×2 drive type car has only one main drive shaft. A 6×4 drive type car has an intermediate drive shaft, a main drive shaft, and a middle and rear axle drive shaft. The 6×6 drive type automobile not only has the intermediate drive shaft, the main drive shaft, the middle and rear axle drive shafts, but also the front axle drive drive shaft. The intermediate transmission shaft of long-wheelbase vehicles is generally provided with a transmission shaft intermediate support. It is composed of a support frame and a support. In the traditional structure of the transmission shaft telescopic sleeve, the spline sleeve and the flange fork are welded together, and the spline shaft is welded to the transmission shaft tube.


The transmission shaft of GWB Company changed the traditional structure, welded the spline sleeve and the transmission shaft tube into one body, and made the spline shaft and the flange fork into one body. The rectangular tooth spline is changed to a large pressure angle involute short tooth spline, which not only increases the strength but also facilitates the extrusion forming, and meets the needs of high torque working conditions. The tooth surface of the telescopic sleeve and spline shaft is coated with a layer of nylon material, which not only increases the wear resistance and self-lubrication, but also reduces the damage to the drive shaft caused by the impact load and improves the cushioning capacity.


We have first-class production line and strict management system.
