The specific embodiment:

Embodiment:

As shown in Figure 1, the utility model is by preceding bearing 1, bearing pin 2, leaf spring 3 before first, first bearing 4, first connecting rod 5, stabilizer rod 6, stabilizer rod bearing 7, cover plate 8, backing plate 9, bolt 10, damper 11, upper bracket 12, lower bracket 13, middle bearing 14, hanger 15, leaf spring 16 before second, second bearing 17, second connecting rod 18, stabilizer rod 19, first propons 20, backing plate 21, upper bracket 22, nut 23, rear support 24, hanger 25, bolt 26, second propons 27 is formed, its characteristics are: carriage frame is equipped with preceding bearing 1, solid on vehicle frame by bolt, leaf spring 3 before the lower end of preceding bearing 1 is equipped with first, connect by bearing pin 2, vehicle frame is equipped with middle bearing 14, hanger 15 is equipped with in the lower end of middle bearing 14, leaf spring 3 before one end of hanger 15 connects first, between preceding bearing 1 and the middle bearing 14 first bearing 4 is housed, connecting rod 5 is equipped with in first bearing, 4 lower ends, dress stabilizer rod 6 on the connecting rod 5, dress stabilizer rod bearing 7 on the stabilizer rod 6, stabilizer rod bearing 7 is contained on first propons 20, leaf spring 3 before first, cover plate 8, backing plate 9, be fixed on first propons 20 by bolt 10, between first bearing 4 and the middle bearing 14 upper bracket 12 is housed, dress damper 11 on the upper bracket 12, damper 11 is connected with lower bracket 13, lower bracket 13 is contained on the first preceding leaf spring 3, on leaf spring 3 before being bolted to first, leaf spring 16 before middle bearing 14 connects second, carriage frame is equipped with rear support 24, by being bolted on the vehicle frame, the lower end dress hanger 25 of rear support 24, hanger 25 is connected with leaf spring 16 before second, between middle bearing 14 and the rear support 24 second bearing 17 is housed, by being bolted on the vehicle frame, the lower end dress second connecting rod 18 of second bearing 17, the lower end dress stabilizer rod 19 of second connecting rod 18, dress stabilizer rod bearing 7 on the stabilizer rod 19, stabilizer rod bearing 7 is contained on second propons 27, interfix and be one, leaf spring 16 before second, cover plate 8, backing plate 21, be fixed on second propons 27 by bolt 10, load onto bearing 22 between second bearing 17 and the rear support 24, dress damper 11 on the upper bracket 22, damper 11 is connected with lower bracket 13, lower bracket 13 is contained on the second preceding leaf spring 16, on leaf spring 16 before being bolted to second, above structure all is contained on the vehicle frame of vehicle frame other end symmetry.

During use,

After car load loads, load is delivered on preceding bearing 1, middle bearing 14 and the rear support 24 by vehicle frame, because bearing 1, middle bearing 14 before the two ends of leaf spring 3 are fixed in before first, first propons 20 is fixed at the middle part, bearing 14 and rear support 24 during the two ends of leaf spring 16 are fixed in before second, second propons 27 is fixed at the middle part.Under the effect of load before first before the leaf spring 3 and second leaf spring 16 elastic deformations take place, two ends move down, thereby cause vehicle frame to move down with respect to first propons 20 and second propons 27.Along with moving down of vehicle frame, damper 11 begins to shorten, and produces dumping force.

When car load travels on flat road surface unexpected cross ditch or bank after, before first before the leaf spring 3 and second leaf spring 16 deform since before first before the leaf spring 3 and second leaf spring 16 are elastic bodys, produce elastic oscillation, cause the vehicle frame up-and-down movement.Damper 11 extended, shortened along with the motion of vehicle frame this moment, absorbed the energy of suspension vertical shake, and was converted into thermal dissipation and falls, and car load is vibrated decay to disappearance rapidly.

When car load is turned with certain speed, because the effect of centripetal force makes car load generation inclination, thereby make left and right wheels that vertical relative displacement be arranged, this moment, stabilizer rod 6,19 was turned round, and can increase the roll angular rigidity of suspension, thus the angle of roll of vehicle body when reducing car load and turning to.

After the car load carrying,, make two bridge carryings evenly because first propons 20 and second propons, 27 wheelbases are short.
