Bågaxlar

Bågaxlar, known in English as beam axles or dead axles, are a fundamental component in vehicle suspension systems. They consist of a single, rigid beam that connects two wheels, typically on the same axle. This design is characterized by its simplicity and robustness. Unlike independent suspension systems where each wheel moves separately, the wheels on a bågaxel are constrained to move in unison. This means that any vertical movement or angle change experienced by one wheel directly affects the other wheel on the same axle.

Historically, bågaxlar were a common feature in early automobiles due to their straightforward engineering and cost-effectiveness. They are still widely used today, particularly in heavy-duty trucks, buses, and some trailers, where their strength and ability to support significant loads are paramount. In these applications, the rigid connection provides excellent stability and load distribution. However, the lack of independent wheel movement can lead to compromises in ride comfort and handling, especially on uneven surfaces, as one wheel’s articulation is directly transmitted to the other. This can result in a less smooth ride and reduced tire contact with the road in certain situations. Despite these limitations, the enduring presence of bågaxlar in various vehicle types underscores their continued relevance and suitability for specific demanding applications.
