drivakslene

Drivakslene, commonly translated as drive shafts, are mechanical shafts that transmit torque from a vehicle's transmission or differential to the wheels. They are essential to the drivetrain of most rear-, front-, and all‑wheel drive systems, allowing power delivery while accommodating steering angles, suspension travel, and axle articulation.

Most drivakslene consist of a tubular steel or aluminum shaft, a pair of joints at either end, and protective boots. In modern cars the joints are usually constant-velocity (CV) joints that maintain a steady rotational speed despite angle changes. Some designs use universal joints (U-joints) with a center bearing in longer shafts to support weight and minimize deflection. The shaft is lubricated and sealed to protect internal bearings from dirt and moisture.

Configurations vary with drivetrain layout. Front‑wheel drive typically uses a short drive shaft with CV joints at both ends. Rear‑wheel and four‑wheel drive systems may use one or more longer shafts with U‑joints and, in some cases, a center bearing. Telescoping, slip‑joint designs allow length adjustment for suspension movement and vehicle pitch changes.

Common failure modes include torn CV boots leading to loss of grease and joint wear, worn U‑joints, imbalance, or damage from impact. Symptoms include clunking or clicking on turns, vibrations at speed, or grease leakage. Maintenance emphasizes regular boot inspection, joint lubrication when serviceable, and replacement of worn or damaged shafts to preserve driveline integrity.
