AI Technical Summary
In the existing technology, the anti-collision protection structure of the transfer case cannot effectively disperse the impact force, causing the impact load to be directly transmitted to the inside of the transfer case and damaging the precision components.
A protection mechanism for a coaxial drive axle was designed, which adopts a suspension support frame and anti-collision plate structure, including an arc-shaped connecting plate and an aluminum anti-collision plate. It absorbs impact energy through sliding fit and arc deformation, and avoids rigid impact from being transmitted to the transfer case.
It effectively disperses and absorbs impact energy, protects the transfer case and transmission system from damage, and improves the vehicle's collision safety and ride comfort.
