The end at lateral suspension beam 6 two ends respectively by rubber nodal point 9 flexible fastening on supporting box 5, a pair fitting seat 11 is provided with at the top of supporting box 5, the both sides of rubber nodal point 9 are respectively fixed on two fitting seats 11 of supporting box 5 by clamping bolt 10 is vertical, the vertical mandrel running through rubber nodal point 9 of clamping bolt 10, coordinates with the bolt hole on fitting seat 11 and is fixed on fitting seat 11 by rubber nodal point 9.
Be provided with the stopping seat 14 raised up in the side of each fitting seat 11, stopping seat 14 for stopping the lateral displacement of rubber nodal point 9, stopping seat 14 and the machine shaping of fitting seat 11 one.
One or more pieces pads 12 can be provided with bottom the mandrel of rubber nodal point 9 and between fitting seat 11 and between the top and clamping bolt 10 of rubber nodal point 9 mandrel, the bilateral symmetry of rubber nodal point 9 is provided with two groups of pads 12, for regulating the vertical setting height(from bottom) of linear electric motor 7, pad 12 is for having the pad 12 of locking spline structure, prevent when the high vibration and the friction that are subject to vehicle, loosening and phenomenon of rupture, to ensure reliability and safety during vehicle operating appears in pad 12.
As shown in Figure 3, a kind of locking spline pad, comprise multiple shim body 15, shim body 15 have for the bolt hole 16 through clamping bolt 10, the side that shim body 15 is positioned at bolt hole 4 is provided with an opening 17, through a spline pin 18 in opening 17, spline pin 18 is limited in the opening 17 of shim body 15, the spline of pad 12 is realized by coordinating between spline pin 18 with opening 17, the structure of multiple shim body 15 is identical, spline pin 18 is simultaneously through the opening 17 in multiple shim body 15, a spline pin 18 can realize the function of locking spline simultaneously to multiple pad 12.In the present embodiment, in the both sides of each rubber nodal point 9, one group of pad 12 is respectively set, the structure of pad 12 diminishes relative to prior art, the structure of split is become from the U-shaped structure of entirety of the prior art, decrease vehicle and vibrate impact on pad for a long time, effectively avoid pad to occur the phenomenon of fracture, the safety and reliability of vehicle operating is ensured further.
As shown in Figure 2, in the present embodiment, a spline pin 18 is all fixed at the top of the stopping seat 14 of the fitting seat 11 in rubber nodal point 9 both sides, a spline pin 18 is fixed equally relative to the opposite side of stopping seat 14 at each fitting seat 11, being fixed on spline pin 18 on stopping seat 14 for limiting the one or more pads 12 being arranged on rubber nodal point 9 one side roof part, being fixed on spline pin 18 on fitting seat 11 for limiting the one or more pads 12 being arranged on rubber nodal point 9 bottom simultaneously.
As shown in Figure 5, in the present embodiment, spline pin 18 preferably adopts cylindrical body, the bottom of spline pin 18 has outside thread 19, correspondingly on stopping seat 14 and fitting seat 11, offer the female screw (not shown) of tool, spline pin 18 and being fixedly secured by screw thread between stopping seat 14 and fitting seat 11 is linked together, and ensures that spline pin 18 can not loosen in vehicle operation.
As shown in Figure 4, the upper shed 17 of shim body 15 is the U-shaped hatch frame coupled together by two straight line side 17a and arc-shaped edges 17b, wherein, the arc-shaped edges 17b of opening 17 is the quarter circular arc of R by two radiuses and to connect a segment length of two circular arcs be that the straightway 17c of h forms.Be linear contact lay when this shape can ensure that shim body 15 contacts with spline pin 18, area of contact during cushioning can not be reduced because of drilling in shim body 15 simultaneously, realize spline and cushioning is firmly firm.In addition, arrange the shape that two circular arcs add straight line, compare a semi-circle, when spline pin 18 relatively rotates with shim body 15, relative angle n ° that produces between them can be smaller, can play reasonable anti-spline effect like this.
As shown in Figure 6 and Figure 7, in the present embodiment, the diameter of spline pin 18 is slightly less than the width of U-shaped opening 17, and ensureing, when carrying out the installation of pad 12 with spline pin 18, dismantling, can not affect installation and removal because of fit dimension tension.And, when the center of spline pin 18 and U-shaped opening 17 center on one wire time, the gap between the both sides of spline pin 18 and two straight line side 17a of U-shaped opening 17 is m.If m value is too little, affect coordinating between spline pin 18 with pad 12, if m value is too large, then can make rotation angle n ° excessive, then do not have effective locking spline effect.
When in vehicle operation, when pad 12 occurs loose, pad 12 can rotate, and now, owing to having gap m between spline pin 18 and U-shaped opening 17, shim body 15 can with the center of bolt hole 16 for axis rotation one angle n ° when rotating.U-shaped opening 17 in shim body 15 will contact with spline pin 18, thus stop the rotation of shim body 15, make pad 12 solid and reliable.That is, when shim body 15 rotates clockwise an angle n ° around bolt hole 16 with radius R 1, spline pin 18 contacts with shim body 15 at A point place, produces spline effect to shim body 15; When shim body 15 rotates counterclockwise with radius R 1 around bolt hole 16, spline pin 18 contacts with shim body 15 at B point place, thus produces spline effect to shim body 15.By repeatedly checking, calculate checking, appropriate design goes out the gap m between spline pin 18 and straight line side 17a, ensures that the angle n ° of value that shim body 15 is rotated when rotating controls in less scope, thus makes pad 1 play effective spline effect.
As shown in Figure 2, in the initial period of vehicle operating, major part pad 12 is placed on the top of rubber nodal point 9 mandrel, the spline pin 18 be fixed on stopping seat 14 is utilized this part pad 12 to be played to the effect of locking spline, separately there is minority pad 12 to be placed on the bottom of rubber nodal point 9 mandrel, utilize the spline pin 18 be fixed on fitting seat 11 this part pad 12 to be played to the effect of locking spline.
When needing in running to adjust the relative height between lateral suspension beam 6 and supporting box 5, the pad 12 at rubber nodal point 9 mandrel top is moved to the bottom of rubber nodal point 9 mandrel, thus regulate the height of lateral suspension beam 6, and then regulate the suspension height of linear electric motor 7.
When needing the pad 12 at rubber nodal point 9 mandrel top to move on to the bottom of rubber nodal point 9 mandrel, first need to unclamp and take out the clamping bolt 10 installed, lifting lateral suspension beam 6, to meeting the height increasing spacer thickness, when keeping spline pin 18 motionless, by the pad 12 at rubber nodal point 9 mandrel top from laterally directly taking out, direct by one or more pieces pads 12 of taking out from top bottom from laterally inserted rubber nodal point 9 mandrel again, and ensure the opening 17 of pad 12 and the accurate fit being fixed on the spline pin 18 on fitting seat 11, finally put down lateral suspension beam 6, insert clamping bolt 10, realize being fixedly connected with between rubber nodal point 9 with fitting seat 11.Two groups of pads 12 of rubber nodal point 9 both sides, regulate simultaneously, and adjust same quantity.
This gasket construction is simple and reasonable in design, by coordinating between spline pin 18 and the opening 17 of shim body 15, effectively can prevent the rotation between multiple pad 12, extend the working life of pad 12, ensure vehicle operating safety, and, when needs regulate height, do not need dismounting spline pin 18, mounting and adjusting is very convenient.
As mentioned above, plan content given in conjunction with the accompanying drawings and embodiments, can derive similar technological scheme.In every case be the content not departing from technical solutions of the utility model, any simple modification done above embodiment according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
