Abstract
The invention relates to the technical field of vehicle suspension device, in particular to a double-vibration damper spiral spring suspension system with a transverse stable mechanism. In order to overcome the defects that the prior large stroke spiral suspension system can not be provided with the prior anti-sway bar or the second vibration damper due to the limitation of structural space, the invention provides the double-vibration damper spiral spring suspension system with the transverse stable mechanism. The system comprises two suspension supporting seats and spiral springs arranged outside the suspension supporting seats; the transverse torsional spring stable mechanism is arranged between the two suspension supporting seats; and each of the two suspension supporting seats is provided with a primary vibration damper and a secondary damper respectively. The system greatly saves mounting space of the transverse stable mechanism, improves transverse rigidity and transverse stability of the suspension system, increases the damping of the suspension system, and ensures that the rotation angle of wheels is not affected.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, technical scheme of the present invention is done detailed description.
Referring to Fig. 1 and Fig. 2, a kind of double-shock absorber screw spring suspension system with transversal stabilizing mechanism, comprise two strut mounts 2 and the coil spring 4 that is separately positioned on the strut mount outside, coil spring 4 belows are provided with the lower suspension link 7 that is connected with strut mount 2, two strut mounts 2 are captiveed joint with suspension cross sill 11 by suspension entablatrance 3, are provided with torsional spring type transversal stabilizing mechanism 1 between described two strut mounts 2; Described two strut mounts 2 are respectively equipped with main damper 13 and secondary shock absorber 14.
Described main damper 13 is installed in coil spring inside, and secondary shock absorber 14 is installed in the coil spring outside.The upper end of main damper 13 is installed on the strut mount 2, and the lower end of main damper 13 links to each other with lower suspension link 7 by suspension 5.The upper end of secondary shock absorber 14 is installed on the front side plate of strut mount 2, and the lower end of secondary shock absorber 14 is connected with lower suspension link 7 by damper bracket 6.
The outer end of lower suspension link 7 is equipped with limiting steering device 15, when this suspension system is used for steeraxle, can utilize the hard-over of these limiting steering device 15 limiting wheels.
Referring to Fig. 2 and Fig. 3, torsional spring type transversal stabilizing mechanism 1 is made up of parts such as torsion spring 10, torsion spring hold-down arm 8, torsion spring stationary pipes 9, axle sleeve 18, swing arm 20, pull bars 12.The two ends of torsion spring 10 are fixing by torsion spring hold-down arm 8; The centre of torsion spring is equipped with torsion spring stationary pipes 9, can prevent that torsion spring from bending by actv. in twist process; Torsion spring hold-down arm 8 is connected with axle sleeve 18 by spline, make torsion spring hold-down arm 8 to rotate together along with axle sleeve 18, the plane on the strut mount 2 is close in one side of torsion spring hold-down arm 8, the another side is equipped with outer back-up ring 17, outer back-up ring 17 snaps in the groove of axle sleeve 18, makes that torsion spring hold-down arm 8 can not be along the axial motion of axle sleeve 18; Torsion spring stationary pipes 9 is installed in the endoporus of axle sleeve 18 by inner shield ring 16; Axle sleeve 18 is installed in by slide bushing 19 in the endoporus of strut mount 2, and axle sleeve 18 can rotate in the endoporus of strut mount 2; On swing arm 20 welding and the axle sleeve 18, the outer end of swing arm 20 links to each other with lower suspension link 7 by pull bar 12.
When lower suspension link 7 swings up and down along with the bob of wheel, the pull bar 12 also thereupon swing of swing arm 20 by linking to each other with lower suspension link 7; Because torsion spring hold-down arm 8 adopts spline to be connected with axle sleeve 18, axle sleeve 18 adopts welding fixing with swing arm 20, during swing arm 20 swings, and torsion spring hold-down arm 8 swing together thereupon; Because the two ends of torsion spring 10 are fixing by torsion spring hold-down arm 8, so the bob of wheel finally can make torsion spring 10 two ends do corresponding rotation.When the wheel bob at suspension two ends was inconsistent, the angle that rotate at torsion spring 10 two ends was also different, and torsion spring 10 can twist, and the moment of output finally is delivered to becomes the power that is applied on the wheel on the wheel, and at this moment, the torsional spring type transversal stabilizing mechanism begins to work.
The present invention adopts the torsional spring type transversal stabilizing mechanism, make it can reasonably be arranged between the strut mount that structure is very compact, the space is narrow and small relatively, also do not influence the inner parts such as main reduction gear, electric drive motor of installing of strut mount, thereby improved the lateral stiffness of suspension system, improved the lateral stability of suspension system.Double-shock absorber of the present invention has not only increased the damping of suspension system, and has guaranteed that the angle of wheel is unaffected.
