The specific embodiment
In Fig. 1 and 2, pointed out device of the present invention in detail, be double cross arm independent suspension, comprising wheel set 1, wheel can be a wheel flutter, it also can be drive wheel, outer universal drive assembly 2 links to each other with axle drive shaft 18, and axle drive shaft 18 links to each other with diff 16 by interior universal assembly 17, and Top Crossbeam 5 outer ends link to each other by the 1st ball pivot 4 with stub 3, Top Crossbeam 5 the inners link to each other with crank 15, and Top Crossbeam 5 can rotate relative to vehicle frame 6 around bearing pin 23.The spring damping and vibration isolating system is made up of damper spring 8 and shock absorber 7, the upper end locating piece slide block 9 of spring damping and vibration isolating system is in guide rail 11, moved laterally in the guide groove of guide rail 11 by slide block connecting rod 10 pulling slide blocks 9, spring damping and vibration isolating system and slide block 9 pivot by axle 22.Slide block connecting rod 10 and crank connecting link 14 are connected with piston rod 12 bearing pins, and crank connecting link 14 is connected with crank 15 bearing pins, and crank 15 is connected with the Top Crossbeam 5 inner forms of coupler that adopt, and crank 15 can rotate around bearing pin 23.Stabilizer rod column 21 adopts swivel coupling with Panhard rod 19 and lower cross arm 20.
When hydraulic actuating cylinder moves, on the one hand, piston rod 12 pulling crank connecting links 14, crank connecting link 14 drives crank 15 rotations, after turning over an idle travel, crank 15 and lower cross arm 5 connecting places, the tooth engagement of the tooth of coupler crank end and Top Crossbeam end, the moment that produces makes Top Crossbeam 5 around bearing pin 23 rotations, thereby drives wheel set 1 and lower cross arm 20 risings; On the other hand, piston rod 12 pulling slide block connecting rods 10, slide block connecting rod 10 drives slide block 9 edges and moves with the guide rail 11 that vehicle frame 6 is connected, and when eliminating lower cross arm 20 risings, the spring damping and vibration isolating system is to the constraint of vertical deviation.
During land travelling, the spring damping and vibration isolating system will guarantee good location, and play and rotation can not take place.Slide block 9 is stuck in the groove of guide rail 11, as shown in Figure 3, has retrained the vertical and vertical displacement in upper end of spring damping and vibration isolating system, and located lateral is retrained by the guide rail outer end.Spring damping and vibration isolating systems center line and vertical direction have a flare oblique angle, are 3 ° as shown in Figure 4, and during land travelling, ground is delivered to spring damping and vibration isolating system upper end, impulsive force F in the face of traffic blows power cBe decomposed into F C1And F C2, as shown in Figure 5, component F C1And F C2All act on the guide rail, when avoiding wheel bounce to the impact of piston rod.When travelling by land, because wheel bounce causes that the amplitude of Top Crossbeam 5 swings is very little, so the line of centers and the vertical direction that makes the spring damping and vibration isolating system that pitch of wheel still can keep certain included angle.During the wheel bob, the position of Top Crossbeam 5 and spring damping and vibration isolating systems center line position as shown in Figure 6, among the figure, the angle that Top Crossbeam 5 swings up and down is 7 °, solid line is Top Crossbeam 5 dead positions, and dotted line is the position of pendulum on the Top Crossbeam 5, and dotted line is the position of Top Crossbeam 5 bottoms.
For jolting of guaranteeing that vehicle travels by land, the bob of wheel, Top Crossbeam 5 do not swing up and down and have influence on hydraulic actuating cylinder 13 by crank 15, crank connecting link 14 and piston rod 12, design Top Crossbeam 5 not exclusively meshes with the inside and outside tooth in crank 15 coupler junctions, be reserved with certain back lash, Top Crossbeam 5 and crank 15 junctions, be I place among Fig. 1 enlarged drawing as shown in Figure 7, the A of Fig. 7 to view as shown in Figure 8, the back lash of the inside and outside tooth in coupler junction is shown among Fig. 8 10 °.Top Crossbeam 5 around bearing pin 23 turn an angle up and down (angle of idle travel shown in Fig. 8 is 10 °) could drive crank 15 and rotate.When wheel travels bob on land, as long as the angle that Top Crossbeam 5 rotates around bearing pin 23 is no more than the idle travel angle of reservation, Top Crossbeam 5 rotates and does not just affect crank 15, during the wheel bob, crank 15, crank connecting link 14 all is in relative static conditions, so the bob of wheel can not produce frequent impulsive force to hydraulic actuating cylinder 13, wheel pitches and beats position and crank 15 positions as shown in Figure 9, a represents when jumping on the wheel, the position that swings on the Top Crossbeam 5, when on behalf of wheel, b do not beat, the position of Top Crossbeam 5, c represents when jumping under the wheel, the position that Top Crossbeam 5 swings to.When the position of coupler junction tooth and the setting angle of crank 15 should make wheel be in collapsed state, the position that crank 15 turns to did not interfere with vehicle frame 6.
For drive wheel, when wheel rises, can cause the variation of axle drive shaft 18 axial lengths, when wheel is moved up and down, can adapt to the variation of axle drive shaft 18 axial lengths, the CV universal-joint is adopted at two ends at each axle drive shaft, and axle drive shaft 18 is divided into two parts, connects with spline between two parts, when packing up with the permission wheel, the variation of axle drive shaft 18 axial lengths, present technique is applied at present, not within this discovery claim.
Panhard rod 19 connects the lower cross arm 20 of left and right sides suspension by stabilizer rod column 21.When wheel is packed up, lower cross arm 20 rises, stabilizer rod column 21 shortens with the hinge-point distance in the horizontal of lower cross arm 20, on Panhard rod 19 axial lengths is incompressible, if stabilizer rod column 21 is improper with Panhard rod 19 and lower cross arm 20 constraints, Panhard rod 19 can stop the swing of lower cross arm 20 to be risen, therefore, must guarantee that the constraint between stabilizer rod column 21 and Panhard rod 19 and the lower cross arm 20 is suitable, can not limit the degree of freedom of stabilizer rod column 21 in lateral rotation, adopt ball pivot to connect between stabilizer rod column 21 and Panhard rod 19 and the lower cross arm 20, stabilizer rod column 21 links to each other by ball pivot 24 with lower cross arm 20, stabilizer rod column 21 and lower cross arm 20 connecting places, promptly the enlarged drawing at III place is as shown in figure 10 among Fig. 1.
