Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.Should be understood that, embodiment described herein only, for description and interpretation the present invention, is not limited to the present invention.
In the present invention, in the situation that not doing contrary explanation, the noun of locality of use as " upper and lower " normally for direction shown in the drawings or for each parts mutual alignment relationship description word vertically, on vertical or gravitational direction." left and right " is normally for paper width direction shown in the drawings.
As shown in Figure 3, the invention provides a kind of steel plate spring assembly, this steel plate spring assembly comprises stacked Multi-Leaf Springs sheet 1,2, on two adjacent leaves of spring, be formed with respectively the relative locating stud in position 3,5 and locating slot 4,6, this locating stud 3,5 and locating slot 4,6 cooperatively interact and fitting surface is provided with acoustic damping materials coating 7,8.The present invention is by arranging acoustic damping materials coating on the fitting surface between the location cotter way at adjacent two leaves of spring, in Vehicle Driving Cycle process, can eliminate horizontal between steel plate spring assembly light plate spring sheet and noise that longitudinal relative displacement causes, and be convenient to the assembling of locating stud and locating slot.
Wherein, described acoustic damping materials coating 7,8 is preferably urethane foam coating, can be created on locating stud surface or on locating slot inwall by spraying method.When two leaf of spring assemblings, polyurethane foam layer has leading role, is convenient to the assembling of locating stud and locating slot, and efficiency of assembling is improved.Meanwhile, urethane foam can produce distortion, makes to be suitable for more high-precision assembling.Certainly, selectively, acoustic damping materials coating also can select other can acoustic damping materials or high-abrasive material, but be preferably, has certain elasticity and toughness, can produce distortion.
Locating stud in existing steel plate spring assembly and locating slot adopt the structure of square cotter and square hole more, and this is unfavorable for assembling.The first leaf of spring 1 as shown in Figure 3 and the second leaf of spring 2 need first a plurality of square holes and square groove to be alignd one by one, just can assemble, and waste time and energy.In the present embodiment, for ease of assembling, the first locating stud 3 and the second locating stud 5 are all preferably cylindrical positioning pins, and correspondingly, the first locating slot 4 and the 26 locating slot are cylinder groove.Straight pin is providing in the situation of equal accuracy location with respect to square pin and other shape localization pins, assembles simplyr, and efficiency is higher.
In addition, acoustic damping materials coating is preferably around the outer circumferential face setting of locating stud, and as shown in Figure 3, the first acoustic damping materials coating 7 is sprayed on the outside of the first locating stud 3, and the second acoustic damping materials coating 8 is formed on the outside of the second locating stud 5.More preferably, the outer circumferential face of acoustic damping materials coating 7,8 forms taper, can play leading role like this when pin coordinates with groove, and assembling is simple.Because acoustic damping materials coating has taper side face, at locating stud, insert in the process of locating slot, the taper side face of coating is squeezed gradually and is out of shape, and cotter way is coordinated closely, and positioning precision is higher.
In Fig. 3, be only example, steel plate spring assembly can comprise the stacked leaf of spring more than two, forms above-mentioned pin-and-hole and coordinate between adjacent leaf of spring.Similarly, in Fig. 3, be only example, on every block plate spring sheet, locating slot or the locating stud more than two can be set.And more preferably, a plurality of locating studs or locating slot are symmetrically distributed in the both sides of fastening mounting hole, make structure location and stress equalization, especially when being subject to lateral force or longitudinal force.Finally after completing pin-and-hole cooperation, fastening mounting hole is set on the central position of this steel plate spring assembly, this fastening mounting hole runs through stacked Multi-Leaf Springs sheet, utilize fastening piece 9 such as clamping bolt etc. through this fastening mounting hole with fastening Multi-Leaf Springs sheet.For further reinforcing tightening, a plurality of spring clip (not shown) also can be set on steel plate spring assembly, the plurality of spring clip arranges along length direction (being the length direction of leaf of spring or the paper width direction in the figure) interval of steel plate spring assembly, especially at the two ends of steel plate spring assembly, and each spring clip is around the periphery setting of steel plate spring assembly, further to clamp stacked Multi-Leaf Springs sheet.
On the basis of steel plate spring assembly described above, the present invention also provides a kind of vehicle, on this vehicle, is provided with according to steel plate spring assembly of the present invention.Thereby this vehicle also has advantages of steel plate spring assembly as above.Vehicle in motion, even if produce the active force that makes horizontal between leaf of spring or longitudinal relative displacement, due to the existence of acoustic damping materials coating, is minimized or eliminates brought various noise.
Below describe by reference to the accompanying drawings the preferred embodiment of the present invention in detail; but; the present invention is not limited to the detail in above-mentioned mode of execution; within the scope of technical conceive of the present invention; can carry out multiple simple variant to technological scheme of the present invention, these simple variant all belong to protection scope of the present invention.
It should be noted that in addition, each concrete technical characteristics described in above-mentioned embodiment, in reconcilable situation, can combine by any suitable mode, for fear of unnecessary repetition, the present invention is to the explanation no longer separately of various possible compound modes.
In addition, between various mode of execution of the present invention, also can carry out combination in any, as long as it is without prejudice to thought of the present invention, it should be considered as content disclosed in this invention equally.
