Illustrate for the structure of the present embodiment and specific implementation below:
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 in addition illustrate for other well-known parts in ride-control.Damping frame 1 comprises: upper plate 10, lower plate 11, limiting stopper adapter plate 12, inner frame 13, polysulphide rubbers 14, purchasing ore 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 ensure that spring holder 8 can ensure that certain weld strength is for support helix spring 5, coil spring 5 top assembling dust boot 3, dust boot 3 is mainly used for protecting shock absorber piston rod 6, make shock absorber piston rod 6 not by muddy water, the infringement of dust, the upper end running in bearings 2 of dust boot, the object of bearing 2 is when vehicle turns in actual travel process, shock absorber is rotated together along with wheel, the object of bearing 2 is also to support damping frame 1 simultaneously, damping frame 1 is assemblied in bearing 2 upper end, 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, breakdown when preventing shock absorbers compression from arriving the limit.End cap 7 is assemblied in the upper end of cylinder barrel 9 by the technique press-fited, and to prevent limiting stopper 4 from clashing into cylinder barrel 9 when compressing, end cap 7 has been effects of protection.
The purchasing ore 15 of damping frame 1, polysulphide rubbers 14, inner frame 13 are assemblied between upper plate 10 and lower plate 11, and purchasing ore 15, inner frame 13, polysulphide rubbers 14 three are sulfided by sulfuration process, form an entirety.The upper plate 10 of damping frame 1, lower plate 11, limiting stopper adapter plate 12 are all strike out shaped piece, and three is combined by welding process.The hold-down bolt 16 of damping frame 1 is fitted in above upper plate 10 and lower plate 11 by the technique press-fited 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 be designed by Static stiffness as required, inner frame groove 19 degree of depth is darker, polysulphide rubbers after assembling between inner frame 13 and purchasing ore 15 will be more, Static stiffness is less, and in like manner, inner frame protuberance 20 is thicker, polysulphide rubbers after assembling between inner frame 13 and purchasing ore 15 will be fewer, and Static stiffness is larger.The upper and lower end face of inner frame 13 is plane and centre has 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 purchasing ore 15 and inner frame 13 sulfide, polysulphide rubbers upper end protuberance 17, polysulphide rubbers lower end protuberance 18 is designed with at the upper and lower end of polysulphide rubbers, polysulphide rubbers upper end protuberance 17, polysulphide rubbers lower end protuberance 18 are uniformly distributed at polysulphide rubbers upper and lower end, are close to respectively with upper plate 10, lower plate 11 simultaneously.The concrete thickness of polysulphide rubbers upper end protuberance 17, polysulphide rubbers lower end protuberance 18, shape and quantity are determined by different Z-direction Static stiffness, and thickness is thicker, quantity is more, and Static stiffness will be larger.
As shown in Figure 2, damping frame 1 is linked together by inner frame 13 and shock absorber piston rod 6.When vehicle runs into the protrusion on road surface and caves in actual travel process, shock absorber up and down reciprocatingly vibrates, vibration is delivered to inner frame 13 by shock absorber piston rod 6, inner frame 13 will be made to extrude 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 produce distortion, thus absorb vibration.Same, when X is delivered to damping frame 1 to, Y-direction vibration by shock absorber piston rod 6, inner frame 13 to, Y-direction extruding polysulphide rubbers distortion, thus makes polysulphide rubbers absorb the vibration of X to, Y-direction at X.Static stiffness is larger, and when equal stressed size, polysulphide rubbers distortion is more difficult, and the effect absorbing vibration is also poorer, and car load traveling comfort is also poorer.
The damping frame of shock absorber of the present invention can provide multiple directions (X to, Y-direction, Z-direction, X to, Y-direction, Z-direction be consistent from car load system of axes) different Static stiffness, damping frame is designed to the thickness of different polysulphide rubbers upper end protuberances 17 and polysulphide rubbers lower end protuberance 18, shape and quantity, can draw different Z-direction Static stiffness; Be designed to different inner frame groove 19 shapes, the degree of depth, position and inner frame protuberance 20 shape, thickness, position, can draw different X to Y-direction Static stiffness, thus reach the object improving 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 simultaneously or one has to alleviate and impacts and the strength member of vibrating function, the quality of damping frame 1 performance design directly has influence on shock absorber and alleviates and impact and the effect of vibration.The invention provides a kind of X that can provide to the ride-control of, the different Static stiffness of Y-direction, Z-direction, this ride-control the vibration of road pavement all directions transmission can carry out attenuation and absorption, improves vehicle handling stability and travelling comfort.
Above with reference to the accompanying drawings of the preferred embodiments of the present invention, those skilled in the art do not depart from the scope and spirit of the present invention, and multiple flexible program can be had to realize the present invention.For example, to illustrate as the part of an embodiment or the feature that describes can be used for another embodiment to obtain another embodiment.These are only the better feasible embodiment of the present invention, not thereby limit to interest field of the present invention that the equivalence change that all utilizations specification sheets of the present invention and accompanying drawing content are done all is contained within interest field of the present invention.
