IMPACT-RESISTANT SUSPENSION Russian patent published in 2012 - IPC F16F7/14 F16F15/04 

FIELD: machine building.

SUBSTANCE: impact-resistant suspension includes rope shock absorbers located inside the base and frame. Frame is made of flexible steel rope and consists of two belts of ropes, which are distributed along sectors. Number of sectors is equal to number of suspension assemblies. Upper and lower belts are made in the form of closed circuits divided into equal number of sections in the form of pieces of ropes. Pieces of ropes of upper belt are passed through bushing supports of external frame at an angle to adjacent sides of the frame. Free ends of ropes of upper belt are connected by means of flexible connection to suspension assemblies. Pieces of ropes of lower belt are passed through bushing supports of platform with possibility of being moved relative to supports, at an angle to adjacent sides of the platform. Pieces of ropes of upper and lower belts envelope the friction element in the form of reversing loop and form structure in the form of equal mutually opposite triangles. Friction element is made in the form of cylindrical housing with centring hollow pin and two disc-shaped parts and arranged in forks of support stands. Disc-shaped parts are located coaxially on the pin with possibility of being turned and provided with a through hole connected to annular groove. Suspension assemblies are connected to the base of structure by means of bed plate and made in the form of elastic-plastic shock absorbers. Stocks of shock absorbers are connected through eye lugs by means of flexible connections to free ends of ropes of upper belt.

EFFECT: higher impact protection efficiency.
