专利摘要:
The invention is concerned with an absorbing spring involving the hydrostatic compression of an elastomer, comprising a tight casing constituted by a deformable, bent elastic tube of flattened section, filled with elastomer. A central core is embedded in the elastomer, the core being made of elastic material, the coefficient of heat expansion of which is lower than that of the tube. The invention finds particular application in the manufacture of absorbing devices. 公开号:SU847943A3 申请号:SU772477052 申请日:1977-04-22 公开日:1981-07-15 发明作者:Жарре Жан;Жарре Жак 申请人:Сосьете Д Эксплуатасьон Де Рессорото-Амортиссер Жарре (Фирма); IPC主号:
专利说明:
The invention relates to mechanical engineering, namely, to hydrostatic shock absorbers. A shock absorber is known, comprising a hermetic body, made in a bottom of a curved elastic tube, flattened in cross section and filled with elastomer C. The disadvantage of this shock absorber is that it is sensitive to IQ as the ambient temperature changes. This is because the thermal expansion coefficient of the tube is much lower than the thermal expansion of the compressed elastomer. In addition, it has a very weak damping effect, this is due to the fact that the movements of the elastomer in the tube have a small range due to the minimal change in the internal cross section of the pipe during its elastic deformation; The purpose of the invention is to improve the damping and reduce the influence of the ambient temperature on the damping characteristics. The goal is achieved in that the shock absorber is provided with a central core made of an elastic material with an extension heat transfer coefficient of less than 1 tube located in the elastomer; elastomer expansion and tubing. It is advisable to make the elastomer with a constant thickness between the core and the tube. The tube can be made of laminated plastic, and the core of steel.
权利要求:
Claims (3) [1] FIG. I shows an S-shaped spring, longitudinal section; in FIG. 2, section A-A in FIG. 1. The S-shaped shock absorber consists of an airtight body made in the form of an elastic tube I bent and cross-sectioned in cross-section. The internal cavity of the tube is filled with elastomer 2, in which the central core is located 3. Internal cross-section of tube 1, as well as section of core 3, has an approximately elliptical shape. The space between the tube and the core is filled with an elastomer of approximately the same thickness. The core 3 is made of an elastic material, such as steel, cn without fatigue to withstand the deformations imparted to the shock absorber. Preferably, the large axial section of the core is about ten times larger than its minor axis, and the thickness of the Ecin E tube 1 is 5-10 times the thickness of the elastomer. The material chosen for the manufacture of the tube 1 must also without fatigue withstand the deformations that the shock absorber undergoes under load; the most suitable material is reinforced plastic. The coefficient of thermal expansion of the core material 3 is less than the coefficient of thermal expansion of the tube material, and the partial division of the inner cross section of the tube by the cross section of the core is equal to the partial division of the difference between the expansion coefficients of elastomer 2 and core 3 by the difference of expansion coefficients of the elastomer and tube. The inserts 4 and 5 are fixed at the ends of the shock absorber and pass through the core 3. The maximum load perceived by the shock absorber is 300 kg. The simplicity of the design of the shock absorber allows it to be manufactured serially at a low cost. Claim 1. A shock absorber comprising a sealed enclosure made in the form of a curved elastic tube, flattened in cross section and filled with an elastomer, characterized in that, in order to improve the damping and reduce the influence of the ambient temperature on the damping characteristics, it is provided with a central element in the elasomer a core of elastic material with a coefficient of thermal expansion less than the tube, with the partial separation of the inner cross section of the tube by the cross section of the central core equal to the partial difference between the difference in the expansion coefficients of the elastomer and the central core by the difference in the expansion coefficients of the elastomer and the tube. [2] 2. A shock absorber pop, 1, characterized in that the thickness of the elastomer between the core and the tube is constant. [3] 3. The shock absorber on PP. 1 and 2, which is indicated by the fact that the tube is made of complex plastic and the core is made of steel.
