Abstract
The utility model relates to a T-shaped steel plate spring, which is an elastic element with asymmetric cross sections. The cross section of the past spring flat steel is in rectangle, and the neutral layer is positioned in the middle of the spring flat steel; when the steel plate spring bears loads, the tension stress and the pressure stress acting on the spring flat steel are numerically equal. Because the tension resistant strength of metallic materials is less than the pressure resistant strength, the rectangular spring flat steel forming into the steel plate spring often begins cracking from tension face. The utility model designs the steel plate spring composed of one rectangular spring flat steel and one or more spring flat steels with asymmetric cross section; the steel plate spring can effectively reduce the tension stress, enhance the fatigue resistance of the steel plate spring, and prolong the service life, and can also save material. The utility model can be used as the steel plate spring of the suspended frame part of vehicles.
Description
The utility model relates to a kind of asymmestry section elastic element, particularly the leaf spring of vehicle suspension part.
At present, the leaf spring of vehicle suspension part, the cross section of its spring flat steel is rectangular.The spring flat steel of forming leaf spring is when bearing load, and one surface is subjected to tensile stress, and corresponding reverse side is compression chord then.Rectangle is a symmetrical section, and the neutrosphere of symmetrical section is positioned at the centre of spring flat steel cross section, tensile stress and pressure stress numerically equal.Because metallic material has the characteristic of tensile strength less than compressive strength, under the effect of tensile stress, the rectangle spring flat steel of the leaf spring of formation often begins fracture from tension face during bearing load.
The purpose of this utility model provides a kind of leaf spring, can reduce to act on the tensile stress on the leaf spring when bearing load, has improved the fatigue strength of leaf spring, has also saved material simultaneously.
The utility model is achieved in that a kind of leaf spring, comprises some clips, centre bolt, and its spring flat steel is superimposed upon on the asymmestry section spring flat steel by the single, rectangular piece spring flat steel of roll coil of strip ear.Because the grasswort of the single, rectangular piece spring flat steel of roll coil of strip ear rolls and forms, because the stress direction that is subjected to when the first half of grasswort and Lower Half bearing load is opposite, so can only adopt the rectangle spring flat steel.
The utility model can also be that the asymmestry section spring flat steel adopts tension face than pressurized face width, and its cross section is "T"-shaped spring flat steel.Because the neutrosphere of asymmestry section deflection tension face, to bear when being unidirectional load forever, tensile stress is numerically less than pressure stress, so can adopt the asymmestry section spring flat steel.
The utility model can also be that the asymmestry section spring flat steel can be a slice or multi-disc.
Compare with prior art, the utlity model has good effect.According to material mechanics principle, with respect to the rectangular steel plates spring, the neutrosphere of T steel leaf spring deflection tension face, when bearing same load, tensile stress numerically reduces, and pressure stress numerically increases.Because the tensile strength of metallic material is less than compressive strength, obviously the T steel leaf spring has higher fatigue strength, longer working life than rectangular steel plates spring, has also saved material simultaneously.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is T steel leaf spring of the present utility model and A-A sectional drawing thereof;
Fig. 2 is the cross sectional view of asymmestry section spring flat steel of the present utility model.
By some clips 1, centre bolt 2, the single, rectangular piece spring flat steel 3 of roll coil of strip ear is superimposed upon the T steel leaf spring that constitutes on the asymmestry section spring flat steel 4, neutrosphere 7 deflection tension faces, when bearing load, tension face 5 is subjected to tensile stress, compression face 6 compression chords, and tensile stress is numerically less than pressure stress.With respect to the leaf spring that constitutes by the rectangle spring flat steel entirely, bearing under the situation of same load, tensile stress diminishes, pressure stress becomes big, improved the fatigue strength of leaf spring, prolonged the working life of leaf spring, because each has reduced the part material than rectangle spring flat steel about every flat spring band steel, reached the effect of saving material simultaneously.The spring flat steel of band hanger can only adopt the reason of rectangle spring flat steel to be that the grasswort of the single, rectangular piece spring flat steel of roll coil of strip ear rolls and form, the stress direction that is subjected to when the first half of grasswort and Lower Half bearing load is opposite, if adopt the spring flat steel of asymmestry section to strengthen tensile stress on the contrary, fatigue strength reduces on the contrary.
Material can be selected 55SiMnVB or 60Si for use
2The Mn spring steel.
