VEHICLE SUSPENSION (VERSIONS) Russian patent published in 2007 - IPC B60G21/02 

FIELD: mechanical engineering.

SUBSTANCE: invention can be used in vehicles in which pitch and roll stabilization is required. Proposed suspension contains articulated parallelogram mechanism whose vertical links are coupled with end of horizontally tilted links through hinge joints, and two tie-rods equally tilted to horizontal plane. Vertical links are made in from of two posts provided with telescopic members made in form of cylinder with piston. According to second design versions, vertical links are made in form of posts 5, each provided with two telescopic members. According to third design version, transport suspension contains additional horizontally-tilted links. According to fourth version, vertical links of transport suspension are made in form of posts containing telescopic members made in from of cylinder with piston and provided with spring and nuts in contact with spring. Upper ends of tie-rods are connected with upper parts of posts and are provided with rollers installed for movement along two similar chutes secured on support member of vehicle. According to fifth design version, vertical links of transport suspension are made in form of posts containing telescopic members in form of cylinder with piston and spring and nuts in contact with spring. According to sixth designed version, transport suspension contains additionally pair of side and pair of central shock absorbers coupling support member consisting of upper and lower parts. According to seventh design version, device is furnished additionally with vertical link whose lower end is connected through triple joint with lower horizontally tilted link, and upper end is provided with telescopic member in form of cylinder with piston, spring and nuts in contact with spring. Platform with load can be used as support member. Driving axle of vehicle or equalizer of two axles and axle or fully-articulated suspension of vehicle can be used as lower horizontally tilted link.

EFFECT: improved performance characteristics of vehicle suspension owing to improved stability and steerability of vehicle, simplified design.
