bakaxlarna

Bakaxlarna, or rear axles, are a vehicle’s rear drivetrain components that transmit torque to the rear wheels and support the vehicle’s weight. In most rear-wheel drive and all-wheel drive configurations, the rear axle contains the differential and connects to the wheels via axle shafts, allowing power delivery to the rear wheels. The arrangement can be a solid beam axle, often called a live axle, or an independent rear suspension, where each wheel moves independently.

Solid rear axles consist of a single rigid axle housing that spans the width of the vehicle. The differential is usually integrated into the housing, and the axle is mounted to the chassis or springs, commonly leaf springs in older designs and sometimes coil springs in modern ones. This setup is valued for durability and load capacity, especially in trucks and off-road vehicles.

Independent rear suspension uses separate suspension paths for each wheel, with axle ends connected to wheel hubs via constant-velocity joints or similar arrangements. The differential may be located in a central housing or within a transaxle. IRS provides improved ride comfort, handling, and tire contact during cornering, at the cost of greater complexity.

Key components of bakaxlarna include the differential or bevel gear, axle shafts or half-shafts, axle housing, wheel hubs, bearings, seals, and drive flanges. Maintenance involves inspecting and replacing differential oil, checking seals for leaks, monitoring bearing play, and inspecting CV joints or other linkage for wear. Historically, rear axles evolved from solid beam designs to independent suspensions in many passenger cars, while solid rear axles remain common in many trucks and heavy-duty applications.
