The below illustrates for structure and the specific implementation of the present embodiment:
As shown in Figures 2 and 3, the ride-control of the present embodiment comprises damping frame 1, bearing 2, dust boot 3, limiting stopper 4, coil spring 5, shock absorber piston rod 6, end cap 7, spring holder 8, cylinder barrel 9 etc., does not add explanation for other well-known parts in ride-control in addition.Damping frame 1 comprises: upper plate 10, lower plate 11, limiting stopper adapter plate 12, inner frame 13, polysulphide rubbers 14, outer skeleton 15, hold-down bolt 16, polysulphide rubbers upper end protuberance 17, polysulphide rubbers lower end protuberance 18, inner frame groove 19, inner frame protuberance 20.
as shown in Figure 2, spring holder 8 in ride-control is weld togethers with cylinder barrel 9, need after welding to guarantee that spring holder 8 can guarantee that certain weld strength is to be used for support helix spring 5, coil spring 5 top assembling dust boots 3, dust boot 3 is mainly for the protection of shock absorber piston rod 6, make shock absorber piston rod 6 not be subjected to muddy water, the infringement of dust, the upper end running in bearings 2 of dust boot, the purpose of bearing 2 be when vehicle when the actual travel process turns to, shock absorber can be rotated together along with wheel, the purpose of bearing 2 also is to support damping frame 1 simultaneously, damping frame 1 is assemblied in bearing 2 upper ends, be connected with shock absorber piston rod 6, and the nut that is locked in damping frame 1 upper end is fixed.Limiting stopper 4 is assemblied in the limiting stopper adapter plate 12 of damping frame 1, and the Main Function of limiting stopper 4 is buffering and spacing effect, prevents when shock absorber is compressed to the limit breakdown.End cap 7 is assemblied in the upper end of cylinder barrel 9 by the technique that press-fits, clash into cylinder barrel 9 to prevent limiting stopper 4 when compressing, and end cap 7 has been effects of protection.
The outer skeleton 15 of damping frame 1, polysulphide rubbers 14, inner frame 13 are assemblied between upper plate 10 and lower plate 11, and outer skeleton 15, inner frame 13, polysulphide rubbers 14 threes sulfide by sulfuration process, form an integral body.The upper plate 10 of damping frame 1, lower plate 11, limiting stopper adapter plate 12 are all punch forming parts, and the three combines by welding process.The hold-down bolt 16 of damping frame 1 is fitted in upper plate 10 by the technique that press-fits and above lower plate 11 so that with the connecting of vehicle body.
As shown in Figure 4 be a kind of planform of inner frame 13.The inner frame 13 of damping frame 1 can be realized by machinework and foundry technique, wherein the shape of the shape of inner frame groove 19, the degree of depth, position and inner frame protuberance 20, thickness, position can quiet rigidity as required be designed, inner frame groove 19 degree of depth are darker, polysulphide rubbers after assembling between inner frame 13 and outer skeleton 15 will be more, quiet rigidity is less, and in like manner, inner frame protuberance 20 is thicker, polysulphide rubbers after assembling between inner frame 13 and outer skeleton 15 will be fewer, and quiet rigidity is larger.The upper and lower end face of inner frame 13 is that plane and centre have through hole S, convenient and the assembling of shock absorber piston rod 6 and the locking of top nut.
As shown in Figure 5 be a kind of planform of polysulphide rubbers.Polysulphide rubbers and outer skeleton 15 and inner frame 13 sulfide, be designed with polysulphide rubbers upper end protuberance 17, polysulphide rubbers lower end protuberance 18 at the upper and lower end of polysulphide rubbers, polysulphide rubbers upper end protuberance 17, polysulphide rubbers lower end protuberance 18 evenly distributes at the polysulphide rubbers upper and lower end, is close to upper plate 10, lower plate 11 respectively simultaneously.Concrete thickness, shape and the quantity of polysulphide rubbers upper end protuberance 17, polysulphide rubbers lower end protuberance 18 determines by the quiet rigidity of different Z-directions, and thickness is thicker, quantity is more, and quiet rigidity will be larger.
As shown in Figure 2, damping frame 1 links together by inner frame 13 and shock absorber piston rod 6.Run into protrusion and when depression on the road surface in the actual travel process when vehicle, shock absorber up and down reciprocatingly vibrates, vibration is delivered to inner frame 13 by shock absorber piston rod 6, to make inner frame 13 extruding polysulphide rubbers upper end protuberance 17, polysulphide rubbers lower end protuberance 18, at this moment polysulphide rubbers upper end protuberance 17, polysulphide rubbers lower end protuberance 18 generation distortion, thus vibration absorbed.Same, when X-direction, when the Y-direction vibration is delivered to damping frame 1 by shock absorber piston rod 6, inner frame 13 is out of shape, thereby makes polysulphide rubbers absorb the vibration of X-direction, Y-direction at X-direction, Y-direction extruding polysulphide rubbers.Quiet rigidity is larger, in the situation that equal stressed size, the polysulphide rubbers distortion is more difficult, and the effect that absorbs vibration is also poorer, and the car load traveling comfort is also poorer.
The damping frame of the utility model shock absorber can provide multiple directions (X-direction, Y-direction, Z-direction, X-direction, Y-direction, Z-direction are consistent from the car load system of axes) different quiet rigidity, damping frame is designed to thickness, shape and the quantity of different polysulphide rubberss upper ends protuberance 17 and polysulphide rubbers lower end protuberance 18, can draw the quiet rigidity of different Z-directions; Be designed to different inner frame groove 19 shapes, the degree of depth, position and inner frame protuberance 20 shapes, thickness, position, can draw the quiet rigidity of different X-directions and Y-direction, thereby reach the purpose that improves vehicle handling stability and travelling comfort.
In shock absorber, damping frame 1 is not only as the connector between shock absorber and vehicle body, and the while is the strength member with alleviation impact and vibrating function still, and the quality of damping frame 1 performance design directly has influence on the effect that shock absorber is alleviated impact and vibrated.The utility model provides a kind of ride-control that the different quiet rigidity of X-direction, Y-direction, Z-direction can be provided, and attenuation and absorption is carried out in the vibration that this ride-control can the transmission of road pavement all directions, has improved vehicle handling stability and travelling comfort.
Above with reference to the accompanying drawings of preferred embodiment of the present utility model, those skilled in the art do not break away from scope of the present utility model and essence, can have multiple flexible program to realize the utility model.For example, the feature that illustrates or describe as the part of an embodiment can be used for another embodiment to obtain another embodiment.These are only the better feasible embodiment of the utility model, not thereby limit to interest field of the present utility model, the equivalence that all utilization the utility model specification sheetss and accompanying drawing content are done changes, within all being contained in interest field of the present utility model.
