Drivaxlarnas

Drivaxlarnas is a term used in automotive Swedish to denote the drive axles of a vehicle. The drive axles are the components that transmit engine torque from the transmission to the wheels and simultaneously support part of the vehicle’s weight. In most passenger cars, power is delivered to the front axle in front-wheel-drive layouts, while rear-wheel-drive configurations rely on the rear axle. In all-wheel-drive or four-wheel-drive systems, torque is distributed to at least two axles, usually through a differential and, in some designs, a transfer case or a central differential to vary torque between axles.

Typical drivaxlarnas assembly includes axle shafts (or half-shafts), a differential gearset, CV joints or constant-velocity joints, wheel hubs, bearings, and seals. The design may use solid axles or independent suspension at the wheels. The differential allows wheels to rotate at different speeds during turns, and in many modern systems electronic or mechanical limited-slip devices modulate torque for traction. Final-drive gear ratios and, in some designs, locking mechanisms, influence acceleration and efficiency.

Maintenance focuses on lubrication and seal integrity: periodic differential oil changes, inspection of CV boots and joints, and checking for bearing wear or leaks. Symptoms of problems include clicking noises from joints, vibrations, or uneven tire wear.

Drivaxlarna vary in complexity from simple rear or front axles to advanced all-wheel-drive assemblies with multiple differentials and electronic traction aids. They are central to propulsion, handling, and load-bearing performance across most road vehicles.
