VEHICLE SOLID AXLE SUSPENSION Russian patent published in 2005 - IPC

FIELD: transport engineering; freight trucks with pneumatic springs.

SUBSTANCE: according to invention, pliable to twisting lever 4 of four-point suspension is installed over vehicle axle 3. said lever is connected at one side with vehicle structure 1a, 1b by means of pair of joints 5, 6 spaced across longitudinal axis of vehicle, and at other side, with vehicle axle 3 by other pair of joints 7, 8 spaced across longitudinal axis of vehicle. Fitted at each side of vehicle is at least one tie-rod 11, 12 to direct movement of axle arranged in direction of longitudinal axis of vehicle and connecting axle 3 of vehicle with structure 1a, 1b to provide their displacement relative to each other in vertical, and at least one shock absorbing spring unit 19, 20 between axle 3 and vehicle structure 1a, 1b. Each tie-rod 11, 12 is installed with connection to structure 1a, 1b and vehicle axle 3 by means of joint 13, 14, 15, 16 containing housing, and elastomer arranged between inner hinge joint member and housing for taking forces in several directions and twisting between mated members. Hinge joint 13, 14 connecting tie-rod 11, 12 with vehicle structure features rigidity characteristic higher than that of hinge joints 15, 16 coupling tie-rod 11, 12 with vehicle axle. Invention provides optimization of dynamics of movement, reduction of vibrations, wear and provision of higher side rigidity of axle, reduction of number of separate parts, improvement of repairability and reduction of weight of unsprung parts.

EFFECT: improved suspension of vehicle solid axle.
