Abstract
The invention discloses a steel plate spring. The steel plate spring comprises rolling ears, steel plate sheets, a first bolt and spring clips, wherein the bolt is arranged on one set of steel plate sheets in a penetrating manner; the rolling ears are respectively arranged at the two ends of the steel plate sheets; the rolling ears are provided with the spring clips; each spring clip is composed of a second bolt, a sleeve, a bracket and a nut; the sleeve is arranged at the outer side of each second bolt; the second bolts are arranged on the brackets in the penetrating manner; the nuts and the second bolts are fastened in a threaded connection manner. According to the steel plate spring, friction is generated by relative sliding between the steel plate sheets so as to accelerate the attenuation of the vibration of a frame and improve the using comfort of vehicles; the steel plate spring is simple in structure and low in production cost, so that the steel plate spring can be applicable to large-batch production.
Description
Technical field
The present invention relates to a kind of leaf spring.
Background technique
For accelerating the decay of vehicle frame and body vibrations, to improve ride of vehicle, in the suspension system inside of automobile, vibration damper is housed, must be provided with elastic element in vibration damper, the quality of elastic element directly affects the using effect of vibration damper.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiencies in the prior art, provides a kind of simple in structure, the reliable leaf spring of working stability.
Technological scheme: in order to realize above purpose, a kind of leaf spring of the present invention, it comprises grasswort, sheet steel, the first bolt and spring clip, described bolt is located on one group of sheet steel, the two ends of sheet steel are respectively equipped with grasswort, and grasswort is provided with spring clip;
Described spring clip is comprised of the second bolt, sleeve pipe, support and nut; The outside of described the second bolt is provided with sleeve pipe, and the second bolt is located on support, and the mode that nut and the second bolt are threaded connection is fastening.
The length of described sheet steel does not wait.
Described spring clip is one group.。
Beneficial effect: a kind of leaf spring provided by the invention produces friction by relative sliding between sheet steel, thereby impels the decay of frame weaving, improved the travelling comfort that vehicle uses, and, because this leaf spring is simple in structure, cost of production is low, therefore can adapt to production in enormous quantities.
The accompanying drawing explanation
Fig. 1 is plan view of the present invention;
Fig. 2 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, further illustrate the present invention.
As shown in drawings, be a kind of leaf spring of the present invention, it comprises grasswort 1, sheet steel 2, the first bolt 3 and spring clip 4.
Described bolt 3 is located on one group of sheet steel 2, and the two ends of sheet steel 2 are respectively equipped with grasswort 1, and grasswort 1 is provided with one group of spring clip 4;
Described spring clip 4 is comprised of the second bolt 5, sleeve pipe 6, support 7 and nut 8; The outside of described the second bolt 5 is provided with sleeve pipe 6, the second bolts 5 and is located on support 7, and the mode that nut 8 and the second bolt 5 are threaded connection is fastening.
The length of described sheet steel 2 does not wait, and the first of sheet steel 2 is the longest, and the first of sheet steel and second two ends curve grasswort 1, in order to make chain connection with spring pin and the support or the hanger that are fixed on vehicle frame.
When use is of the present invention, when the normal load that this leaf spring bears is forward, each sheet steel 2 is stress deformation all, the trend that oriented arch is curved, at this moment vehicle bridge and vehicle frame are just adjacent to each other, when vehicle bridge and vehicle frame mutually away from the time, the forward normal load that leaf spring is suffered and distortion just reduce gradually, sometimes even can be reverse.Leaf spring of the present invention is out of shape under load, because relative sliding produces friction, can impel the decay of frame weaving between each sheet, but the dry friction between each sheet, to make the suffered impact of wheel be uploaded to a great extent vehicle frame, reduced suspension and relaxed the ability of impacting, and made each sheet accelerated wear test of spring, this is disadvantageous, therefore, for reducing the wearing and tearing of sheet steel 2, when dress closes sheet steel 2, between each sheet, must coat thicker lubricating grease.
Above-described embodiment is only explanation technical conceive 1 of the present invention and characteristics, its objective is to allow to be familiar with these those skilled in the art and can to understand content of the present invention enforcement according to this, can not limit the scope of the invention with this.All equivalents that Spirit Essence has been done according to the present invention or modification, within all should being encompassed in protection scope of the present invention.
