The specific embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
Shown in Figure 2, the structural representation for the horizontal leaf spring Independent Suspension of the present invention embodiment comprises shock absorber and leaf spring, and shock absorber and leaf spring 10 all are installed on the vehicle frame 1 by bolt.
Wherein, shock absorber comprises a cylindrical shell 4, is provided with a through hole in the bottom of this cylindrical shell 4, the dead in line of the axis of this through hole and cylindrical shell 4, and a piston rod 14 passes this through hole and inserts this cylindrical shell 4.On piston rod 14 and circumferencial direction that through hole cooperates oil sealing 8 has been installed, this oil sealing 8 has been realized the dynamic seal between piston rod 14 and the through hole.Top and bottom at cylindrical shell 4 all fixedly mount a linear bearing, these two linear bearing 3,7 coaxial settings up and down, and all cooperate with piston rod 14, by two linear bearings 3,7 herein, piston rod 14 can slide up and down by the axis along cylindrical shell 4 in cylindrical shell 4.Opening part at cylindrical shell 4 tops has been installed a roller bearing end cap 2 by screw retention, and roller bearing end cap 2 withstands on the end face of linear bearing 3, and at the static seal that is equipped with between roller bearing end cap 2 and the cylindrical shell 4 between seal ring realization roller bearing end cap 2 and the cylindrical shell 4.Middle part at piston rod 14, fixed a piston 5 by endless loop 16, this piston 5 is between two linear bearings 3,7, and the cavity in this piston 5 oil storage cylinder barrel that will be made of cylindrical shell 4 and roller bearing end cap 2 is divided into two leak free cavitys up and down, equal injecting oil liquid in each cavity.For the fluid in two cavitys can be flowed mutually, the conducting direction that is provided with 6,15, two one- way throttle valves 6,15 of two one-way throttle valves on piston 5 is opposite.
An end that stretches out described oil storage cylinder barrel at piston rod 14 is provided with leaf spring mounting hole 9, and an end of described leaf spring inserts in the described leaf spring mounting hole 9.In order to reduce the friction between leaf spring 10 and the leaf spring mounting hole 9, so on two walls up and down of leaf spring mounting hole, all be provided with projection, the upper and lower surperficial corresponding matching of described projection and described leaf spring.
It is to be noted in addition, when this horizontal leaf spring Independent Suspension is used for wheel flutter, the leaf spring mounting hole in the horizontal direction about be provided with the leaf spring deflection space between (what refer to about this paper is said is the fore-and-aft direction of vehicle) two walls and the leaf spring left and right sides face, so that can relatively rotate between piston rod and the leaf spring, piston rod is as the steering yoke bolt of wheel at this moment, and wheel rotates around piston rod when turning to.When this horizontal leaf spring Independent Suspension is used for non-wheel flutter, the leaf spring mounting hole in the horizontal direction about have the very little bearing fit in gap between two walls and the leaf spring left and right sides face, this moment, piston rod can only carry out up-and-down movement, and can not rotate.
This horizontal leaf spring Independent Suspension in use, produce when beating when wheel is subjected to the ground-surface effect, its direction of beating can only be carried out the up-and-down movement of vertical direction with piston rod, has therefore avoided wheel the problem of breakking away to occur, reduce the wearing and tearing of wheel, ensured the service life of tire.Simultaneously, when the piston rod up-and-down movement, the fluid in two cavitys circulate mutually through one- way throttle valve 6,15, and do not need other cylinder barrels to replenish fluid, reduce to vibrate owing to the throttling action of one- way throttle valve 6,15 produces damping.Also have, this horizontal leaf spring Independent Suspension is simple in structure, the space is little, is easy to arrange onboard, the problem of interference can not occur turning to.
Simultaneously, wheel 13 fixes the lower end of the piston rod that is installed in described shock absorber by the fixed cover of installing on the axletree 12 11.
It should be noted that at last: above embodiment only in order to technical scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of various embodiments of the present invention technical scheme.
