Traditional telescopic telescopic shaft structure is splined sleeve and flange welded forks, the spline shaft is welded to the drive shaft tube. The new drive shaft changed the traditional structure, the spline shaft sleeve and pipe welded into one shaft, the shaft spline shaft is integrally formed with the flange fork. And into a large rectangular tooth spline pressure angle involute tooth spline short automotive transmission rates, such as increasing the strength and ease of extrusion, to meet the needs of high torque conditions. In the telescoping tube and splined shaft tooth surface, the overall dip coated with a layer of nylon material, not only increases the wear resistance and self-lubricating automotive transmission manufacturers, but also reduces the load on the drive shaft impact damage automotive drive shafts, improve the buffering capacity. Such shaft spline shaft flange outer tubular seal adds a protective cover, protective cover at the end portion of the two polyurethane rubber seals, telescopic kit form a completely sealed factory space, so stretching spline axis from outside dust erosion, not only dust and rust. Therefore, when assembled in a disposable applicator spline shaft with grease kit, to fully meet the requirements, does not require lubrication glib installed, reducing the maintenance content. Third, the decomposition of (a) the outer gimbal gimbal (RF section) (1) rotating the star wheel and CV, in order to remove the ball. (2) Turn the ball cage until forced two square holes and extraterrestrial wheel straight, remove CV together with extraterrestrial round together. (3) the goal cage fan gear spin on the star wheel square hole, then remove from the CV of the star wheel. (B) the universal joints (VL Festival) (1) Turn the star wheel and CV, pressure the ball cage ball. Note: the star wheel together with the housing is optional, not interchangeable. (2) Remove the ball from the ball cage slot above the star wheel. (C) the inspection of parts (1) Check the alien wheel, the star wheel, CV and depression with or without the ball and wear. (2) the universal joint 6 at the ball requires a certain tolerances, together with the inner planetary gear set into a mating member. (3) If the universal joint gap has been significantly too large, universal joints must be replaced. If the gimbal was smooth and lossless or be able to see the ball in the running, you do not need to replace the universal joint. (4) Check the dust cover is broken, retaining ring and seat are invalid, or should be replaced. [] _ Automotive transmission shaft price _ provided by Prosperous Prosperous Auto Auto.
