FIELD: machine building.
SUBSTANCE: proposed bumper consists of elastic compression elements 7 and expansion elements 5 with linear characteristics. Two-link stiffness corrector mechanism are made up of links 1 interconnected by pivot joint 2. Pivot joints 3 articulate links 1 with plates 4. Pivot joints 2 ate tightened by expansion elastic element 5 and tension regulator 6. Elastic compression elements 7 are arranged between plates 5. Total stiffness of elastic expansion elements 5 equals or somewhat exceeds total stiffness of elastic compression elements 7.
EFFECT: improved design, higher reliability.
