Turvavõllid

Turvavõllid, also known as safety shafts or safety axes in English, are specialized security features incorporated into some vehicles. Their primary function is to mitigate damage to critical components, particularly the engine and transmission, during a frontal impact. In the event of a collision, the turvavõllid are designed to deform or break in a controlled manner, absorbing some of the impact energy. This controlled deformation helps to push the engine and transmission assembly downwards or sideways, away from the passenger compartment. This action aims to prevent the engine and gearbox from intruding into the driver and passenger spaces, thereby enhancing occupant safety. The design and placement of turvavõllid vary depending on the vehicle manufacturer and model. They are often made of relatively brittle materials or feature engineered fracture points to ensure predictable behavior during a crash. The effectiveness of turvavõllid is a factor considered during vehicle safety testing and crash simulations. They are part of a broader system of passive safety features designed to protect occupants in the event of an accident.
