Description
Technical Field
The invention relates to the field of automobile parts, in particular to a front leaf spring for a mine car.
Background
The steel plate spring is an elastic element which is most widely applied in automobile suspensions, and is an elastic beam which is approximately equal in strength and formed by combining a plurality of alloy spring pieces which are equal in width but unequal in length (the thicknesses can be equal or unequal).
When the steel plate spring is installed in an automobile suspension and the borne vertical load is positive, each spring piece is stressed and deformed and tends to be arched upwards. At this point, the axle and frame are brought closer together. When the axle and the frame are far away from each other, the positive vertical load and deformation borne by the leaf spring are gradually reduced and sometimes even reversed.
The main piece ear curl is seriously stressed and is a weak point, and in order to improve the stress condition of the main piece ear curl, the tail end of the second piece is often bent into the ear curl and wrapped outside the main piece ear curl, which is called as a wrapping ear. In order to make the sheets possible to slide relatively when the sheets are elastically deformed, a larger gap is left between the main sheet rolling lug and the second sheet wrapping lug. The two ends of the steel plate spring in some suspensions are not made into rolling ears, and other support connection modes such as rubber support pads are adopted.
The flat rectangular steel plate is bent, and a plurality of stacked springs for the chassis are arranged, wherein one end of each spring is arranged on the hanging bracket through a pin, and the other end of each spring is connected to the girder through a lifting lug, so that the springs can stretch out and draw back. The device is suitable for medium and large trucks at present.
In the typical front and rear leaf spring structure of the current automobile, the cross section of the U-shaped hoop is rectangular, and the structure is adopted by most automobile manufacturers due to the characteristics of simple process, mature design method, strong universality and the like. However, it has low mechanical strength and short service life.
