Description
Technical field
The utility model belongs to elastic element technical field, particularly relates to a kind of stress and regulates leaf spring.
Background technique
Leaf spring is most widely used a kind of elastic element in automotive suspension, and it is wide by some but the elastic beam of an approximately equi-strength that combines of the alloy spring sheet of Length discrepancy, and the thickness of spring sheet can be equal, also can be unequal.Leaf spring is divided into multiple-leaf spring and few sheet spring, multiple-leaf spring is not by multi-disc length etc., the steel disc institute superposition that width is the same gets up, but, after leaf spring has been grown service time, the friction that will slide over each other between each produces noise, and the Relative friction between steel plate also can cause camber of spring, causes traveling irregularity.Few sheet spring is by the thin thick middle in two ends, wide isometric steel disc institute superposition, and the steel plate changes of section of few-leaf-spring is large, and the cross section from centre to two ends is different gradually, and therefore rolling mill practice more complicated, price is also expensive than multiple-leaf spring.
When leaf spring is arranged in automotive suspension, when the normal load of bearing is forward, each spring sheet all stress deformations, the trend that oriented arch is curved.At this moment, vehicle bridge and vehicle frame are just close to each other.When vehicle bridge and vehicle frame mutually away from time, the forward normal load suffered by leaf spring and distortion just reduce gradually, sometimes even can be reverse.Main leaf grasswort is seriously stressed, is weakness, for improving the stressing conditions of main leaf grasswort, often second end also being curved grasswort, wrapping in the outside of main leaf grasswort, being called bag ear.After leaf spring uses for a long time, because zone of high pressure is on the impact of low pressure area, main leaf is occurred, and pressure distribution inequality causes fatigue life short, and between each, phase mutual friction produces noise, changes the vibration frequency of leaf spring.
Summary of the invention
In view of this, the utility model provides a kind of stress to regulate leaf spring, to solve after current leaf spring uses for a long time, because zone of high pressure is on the impact of low pressure area, makes main leaf occur the technical problem that pressure distribution inequality causes fatigue life short.
The technological scheme adopted: provide a kind of stress to regulate leaf spring, comprise the alloy spring sheet group superposed successively, the main leaf two ends being superimposed upon described alloy spring sheet group top are provided with grasswort, second two ends below described main leaf are provided with bag ear, it is characterized in that, described main leaf two ends are provided with compensation paster in the position near described grasswort, described compensation paster one end props up described grasswort, the other end is fixed on the upper surface of described main leaf, in the middle of described compensation paster, natural torsion forms semi-circle, described compensation paster is provided with connecting sheet in described semi-circle both sides, described connecting sheet lower end is connected with padding, the cross section of described padding is right-angled triangle, described padding is clamped between described main leaf and second.
Further, in the middle of described alloy spring sheet group by cover plate and U-bolt fastening, described cover plate is provided with buffer stopper, and each spring sheet of described alloy spring sheet group is fixed together by described cover plate and U-bolt, and described buffer stopper can play buffer function.
As preferably, be provided with stemming between described connecting sheet and described main leaf, described stemming plays buffer function, avoids stress excessive causing to compensate paster fracture.
As preferably, the thickness of described connecting sheet is greater than the thickness of described compensation paster, and suffered by described connecting sheet, stress more described compensation paster is large, and thicker connecting sheet makes the more even of pressure distribution.
The beneficial effects of the utility model: by changing the pressure distribution at main leaf two ends, avoid the problem that fatigue life of causing due to pressure distribution inequality is short, and then improve the smoothness of automobile and reduce noise.
Accompanying drawing explanation
Fig. 1 is the structural representation that a kind of stress of the utility model regulates leaf spring;
Fig. 2 is the structural representation that the utility model compensates paster, connecting sheet and padding.
Embodiment
The following description and drawings illustrate specific embodiment of the invention scheme fully, to enable those skilled in the art to put into practice them.Other embodiments can comprise structure, logic, electric, process and other change.Embodiment only represents possible change.Unless explicitly requested, otherwise independent parts and function are optional, and the order of operation can change.The part of some embodiments and feature can be included in or replace part and the feature of other embodiments.
As illustrated in fig. 1 and 2, a kind of stress is provided to regulate leaf spring, comprise some alloy spring sheets, described alloy spring sheet superposes successively and forms alloy spring sheet group, the centre of each spring sheet of described alloy spring sheet group is tightened together by cover plate 6 and U-bolt 7, described cover plate 6 is provided with buffer stopper 8, plays buffer function.
Main leaf 1 is positioned at the top of described alloy spring sheet group, and the below of described main leaf 1 is second 2, and described main leaf 1 two ends are provided with grasswort 11, and described second 2 two ends are provided with bag ear 21, and described bag ear 21 surrounds described grasswort 11 and has certain gap between the two.
Described main leaf 1 two ends are also provided with and compensate paster 3, and described compensation paster 3 is positioned at the upper surface of main leaf 1, and grasswort 11 described in post is supported in described compensation paster 3 one end, and the other end is fixed on main leaf 1.Naturally be bent upwards to form one end semi-circle 31 in the middle of described compensation paster, described compensation paster 3 is provided with the connecting sheet 4 vertical with described main leaf 1 in described semi-circle 31 both sides, and the length of described connecting sheet 4 is less than the unbent part of described compensation paster 3.Described connecting sheet 4 lower end is provided with padding 5, the cross section of described padding 5 is right-angled triangle, described padding 5 is clamped between described main leaf 1 and second 2, the long right angle side of described padding 5 cross section parallels with described main leaf 1, and consistent with the width of described main leaf 1, short right angle side and the described connecting sheet 4 of described padding 5 cross section are parallel to each other.The thickness of described connecting sheet 4 is greater than the thickness of described compensation paster 3, and suffered by described connecting sheet 4, stress more described compensation paster 3 is large, and thicker connecting sheet 4 makes the more even of pressure distribution.Be provided with stemming between described connecting sheet 4 and described main leaf 1, described stemming plays buffer function, avoids the excessive fracture causing compensating paster 3 of stress.Thus, by changing the pressure distribution at main leaf 1 two ends, avoiding the problem that fatigue life of causing due to pressure distribution inequality is short, and then improve the smoothness of automobile and reduce noise.
