The use of this construction of the balancer allows each axis to move independently on the stroke of the piston relative to the cylinder of the lower telescopic element.

The proposed vehicle suspension system operates as follows.

When moving down (or up) telescopic legs 5 point A (or B), rotating on a circle with radius WA (or AB) around a point In the (or A), falls (or rises) by the same amount as the piston 8 of the telescopic link 6, and moves the point B on the circle with radius BV (or BA) down (or up) by an amount equal to half the magnitude of the displacement of point a (or b). Point B, moving down (or up) through thrust 4, moves the points D and e down (or up) on ellipse trajectories with different curvature of the lower and upper parts of the ellipse (figure 1, 2), with points D and e on the same line parallel to the horizontal plane. At the same time the lower ends of the telescopic legs 5 (points E and F) are located at different levels relative to the horizontal plane. Horizontally-inclined links 2 are arranged at an angle to the horizontal plane, and thrust 4 are written, is based on the tilt of these links, rivnenchina position to the line that contains the points G and D.

When moving points a and b around point B, point D and e are moved in an arc of a circle with radii BG, BD. Match the curvature of the upper and lower parts of ellipses, as well as their difference depends on the ratio of the lengths of the links of the parallelogram mechanism and corresponding movement of the piston 8 and the cylinder 7 with respect to each other.

In option 2, the operation of the device is similar to the operation of the device according to option 1, except that the existing telescopic links 6, placed in the upper and lower part of the uprights 5, allow for the change in the slope of horizontal and inclined sections to the horizontal plane of the upper points D, e and bottom points E, W due to the movement of the piston 8 and the cylinder 7 of the telescopic parts 6 relative to each other to be on the lines that are parallel to each other and the horizontal plane.

The operation of the device according to the variant 3 is the same for option 2, except that the mounting of the hinges horizontally-inclined links (point P, B, M) to the support element 11 of the vehicle forms a duplex balancer to point B.

The work of the transport suspension options 4-6 is similar to the work suspension for option 1, with the difference that the movement of the rollers 16 (points D and e) occurs troughs 17. Reduction victimisations racks 5 and the distance between them, the use of grooves 17 with a given curvature allows for a stepped arrangement of points E and W to lower the centre of gravity of the device, thereby increasing the resistance to the action of lateral forces. Additional vertical element 12 during movement of the device, for example, on a horizontal plane and hitting the obstacle is always in an upright position relative to the horizontal plane, counteracting lateral forces. Bearing device on three pillars: two rollers 16 (points D, e), a telescopic link, allows you to increase the stability of the device.

In option 5, the hinges 9 (B) and 3 (point P) are fixed on the supporting element 11, which may be, for example, the frame of the vehicle, thereby creating a balance device with the center of oscillation (point B), which allows for the movement, for example, on the horizontal plane of the fixed wheels at the points a and b to eliminate the vertical oscillation of the device hitting the obstacle by two shock absorbers, made in the form of telescopic links 6 with adjustable force spring 13 by rotation of the nuts 14. At the same time, points D and e, moving through the grooves 17 with the trajectory arc of a circle with radii BG and BD are parallel to the horizontal plane.

Device for option 6 allows EXT is the promise similar results in the case when the reference element consists of two parts, an upper part can be used the platform of the vehicle, which may be secured cargo, as well as bottom - frame-frame of the vehicle, which interact with links LW, DB and GA, GB, pairs of lateral shock absorbers 19 and the Central damper 20 with nuts regulatory efforts springs and guides. When moving, for example, on the horizontal plane of the wheels, mounted points a, b, elimination of vertical oscillations of the device hitting the obstacle is not only due to the telescopic links 6, and the damper 19 which simultaneously serve to resist longitudinal movement of the lower part of the support element relative to the upper part. At the same time, the upper and lower parts of the support element 11 are always parallel to the horizontal plane. Central absorbers 20 also reduce vibrations moved, attached to the upper side of the support element, in the horizontal and vertical planes.

The operation of the device according to version 7, when the lower horizontal directional link 2 used drive axle 21 of the vehicle is carried out as follows.

When hit, for example, the right wheel 22 nontraceable obstacle arising vertical oscillation device dampens the lower shock absorber (telescopic link 6 with the spring 13 and nuts 14). When hitting right wheel 22 on the obstacle exceeding the stroke of the piston 8 in the cylinder 7 of the telescopic link 6, 5 hour simultaneously moves upward and inward device by tilting the horizontal directional link, in this case, drive axle 21 by moving ravnoudalenie thrust 4, which move the cylinders 7 of the telescopic units 6 hours. The supporting element 11, in this case, the platform on which can be mounted cargo, with a fixed chute 17 and the cylinder 7 additional vertical element 12 moves over the rollers 16 associated with the upper ends of the uprights 5, the right-hand side, and the rollers are aligned parallel to the horizontal plane. The transmission of torque takes place from the power unit through the drive gear (not shown) on the main gear 27 through the double cardan transmission 23 with a sliding spline connection 24 to the wheels 22.

The operation of the device according to version 7, when the lower horizontal directional link 2 use the steering axle 29 of the vehicle, is carried out similarly, except the possibility of using the lower shock absorbers to eliminate slight vertical oscillation racks without moving the rollers along the gutters.

The proposed design of the device allows to achieve excellent performance Manet the arrangement and manageability, it is simple in operation and convenient in maintenance.
