Abstract
The utility model discloses an eccentric adjustment mechanism for an automotive suspension, which comprises an eccentric bolt. The eccentric bolt comprises a screw rod, a first eccentric spacer in extruded and fixed connection with one end of the screw rod, and a second eccentric spacer arranged on the other end of the screw rod and matched with the screw rod; and the joint between the screw rod, the first eccentric spacer and the second eccentric spacer is located at an eccentric position, wherein the screw thread part of the screw rod is processed into two V-shaped grooves so as to lead the transverse section thereof in the shape of figure 8. When the eccentric adjustment mechanism adjusts the position parallels of four wheels, the eccentric spacers are relatively limited within a spacing area in the shape of figure 8; when the screw rod is revolved according to the requirements of specific functions, the eccentric spacers rotate simultaneously; at the same time, two eccentric spacers drive the screw rod to move in the horizontal direction in the groove in the shape of figure 8, and therefore, the position parallels of four wheels of an automobile can be conveniently adjusted.
Description
Technical field
The utility model relates to a kind of mechanism that can implement eccentric adjustment to link, particularly a kind of eccentric adjustment that is used on the automotive suspension.
Background technology
Traditional on the market eccentric adjustment that is used on the automotive suspension mainly contains following 3 kinds at present.
A kind ofly form by conventional bolt, decentralized casing and eccentric nut, the body of rod of bolt closes with eccentric nut is stubborn after passing decentralized casing, and decentralized casing is with after eccentric nut cooperates by square structure, both just can realize rotation synchronously around its axis, the main weak point of this mechanism is the tooling cost height, service life is short, and sliding tooth or transfer phenomenon very easily occur when the adjustment of four-wheel location.The eccentric adjustment of this situation mostly is the disposable appliance that makes at present.
Second kind of bolt, nut and pad by strap cam bar portion or eccentric rod portion formed, and is subjected to the restriction of mechanism itself, and the disadvantage of this mechanism is that setting range is little.
The third is made up of eccentric bolt, eccentric washer and plain nut, eccentric bolt cooperates section structure for lacking the string circle with eccentric washer, its objective is and be used for the location and make eccentric bolt and eccentric washer can realize synchronous adjustment, the main deficiency of this mechanism is that the quality of fit of eccentric bolt and eccentric washer is difficult for guaranteeing, cause in actual adjustment process, easily produce bigger relative slippage between the two, can't accurately locate.
Summary of the invention
The purpose of this utility model is to provide that a kind of accuracy rate height, tooling cost are low, long service life be used for eccentric adjustment on the automotive suspension.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of eccentric adjustment that is used on the automotive suspension, comprise an eccentric bolt, described eccentric bolt comprises screw rod and first eccentric washer that is connected with the extruding of screw rod one end, the other end of screw rod have cooperate with screw rod with second eccentric washer, the junction of described screw rod and described first eccentric washer and second eccentric washer is at eccentric part, wherein: described screw flight partly has been processed into two " V " connected in stars, makes its transversal surface figure of eight.
Good effect of the present utility model is, when adopting the above-mentioned eccentric adjustment that provides to carry out the four wheel locating parameter adjustment, described first eccentric washer is limited in a figure of eight draw-in groove or the similar stop zone by relative with second eccentric washer, according to the concrete function needs, this zone can be along vertical direction setting up and down, the straight line that its line of centers can only be made above-below direction moves, when rotary screw, drive first eccentric washer and second eccentric washer is rotated simultaneously, meanwhile, two eccentric washer force screw rod to do moving of horizontal direction again in " 8 " shape groove, so just can realize the adjustment location of vehicle four wheel locating parameter easily.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.

Among the figure: 10. eccentric bolt; 11. screw rod; " 111. V " connected in star; 12. first eccentric washer; 121. hole; 122. scale mark; 20. second eccentric washer; 201. " 8 " the font eccentric orfice; 202. scale mark; 30. flat gasket; 40. nut.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 5, the eccentric adjustment that the utility model embodiment provides comprises an eccentric bolt 10, described eccentric bolt 10 is formed by screw rod 11 and with first eccentric washer 12 and second eccentric washer 20 that its root extruding is connected, add and earlier screw rod 11 roots are rolled into the decorative pattern shape man-hour, and then eccentric first pad 12 and second eccentric washer 20 are connected with its extruding; The threaded portion of the screw rod 11 here is processed with two " V " connected in stars 111, the transversal surface that makes screw rod is the figure of eight, first eccentric washer 12 and second eccentric washer, 20 eccentric parts are processed with the eccentric orfice 201 of the figure of eight that is complementary with it simultaneously, are used for the location and make the eccentric bolt 10 and first eccentric washer 12 and second eccentric washer 20 can realize synchronous adjustment.Therefore figure of eight eccentric orfice 201 line of centerss here overlap with the positive line of centres with the off-centre of described first eccentric washer 12 and second eccentric washer 20.Described two " V " connected in star angle can be set as and not wait structure, its objective is to prevent that eccentric washer 20 dresses are anti-.
At described screw rod 11 two ends, first eccentric washer 12 and second eccentric washer, 20 outsides also have nut 40.Nut 40 is a hexagonal nut, the described hexagonal nut 40 inboard flat gaskets 30 in addition at described screw rod 11 two ends.
As shown in Figure 3, Figure 4, outer side panel edge 1/2 circumference of described first eccentric washer 12 is provided with scale mark 122, on the outer side panel edge of second eccentric washer 20 1/2 circumference, be provided with scale mark 202, the scale mark at two places all is arranged on separately on the opposite circular arc of " 8 " font eccentric orfice 201, its objective is to strengthen the operability that four wheel locating parameter is adjusted.Described first eccentric washer 12 is provided with hole 121, and the hole is that processing technology is used the hole.The center of the figure of eight eccentric orfice 201 and first eccentric washer 12 is on the same straight line on the hole here (121) and this first eccentric washer 12, and hole 121 and 8 " the font eccentric orfice was listed in the both sides at the center of described first eccentric washer 12 in 201 minutes.Being shaped as of described hole 121 lacks profound circle, described string and the described hole 121, described that lacks profound circle " 8 " the residing straight line parallel in center of font eccentric orfice 201 and described first eccentric washer 12.
As shown from the above technical solution, the utility model embodiment directly pushes the mode that is connected by the screw rod 11 and first eccentric washer 12, has substituted the decentralized casing of processing separately in the conventional confguration, has simplified technology, and has reduced cost; Eccentric bolt 10 and second eccentric washer, 20 fit structures change the figure of eight into by traditional scarce string circle simultaneously, the benefit of doing like this has 2 points, one is that the slippage of second eccentric washer, 20 relative eccentric bolts 10 has reduced, thereby has improved adjusting accuracy, the 2nd, and nut stressed even than the former.In addition, eccentric washer in the traditional mechanism and nut integral structure are separated into 2～3 single-pieces, here 2 single-pieces are meant second eccentric washer 20 and the hexagon nut with flange, 3 single-pieces are meant second eccentric washer 20 and flat gasket 30 and hexagonal nut 40, but so both simplified processing process can improve the degree of utilization of material again greatly.
