Törmäyspalkki

Törmäyspalkki, sometimes referred to as a bumper beam or impact bar in English, is a structural component typically found in vehicles. Its primary function is to absorb and dissipate energy during a low-speed collision. Located behind the vehicle's front and rear bumpers, it is designed to withstand and deform in a controlled manner, thereby protecting more critical components like the chassis and powertrain from damage.

The design and material of törmäyspalkki vary depending on the vehicle type and manufacturer. Common materials include steel, aluminum, or composite materials. The shape is often optimized for crumpling, meaning it is engineered to bend and fold in specific ways to absorb the impact energy. This controlled deformation is crucial for minimizing damage to the vehicle's structure and occupants in the event of a crash.

In modern vehicle design, törmäyspalkki plays a significant role in meeting safety regulations and enhancing overall crashworthiness. While its appearance might be hidden behind the bumper cover, its structural integrity is vital for protecting the vehicle and its occupants during minor impacts, reducing repair costs and improving safety. It works in conjunction with other energy-absorbing structures in the vehicle to manage the forces generated during a collision.
