Abstract

PURPOSE:To obtain the optimum cushioning performance in proportion to the number of passengers, the degree of loads, or others by providing a coil spring with a large spring constant to one part and a small one to the other part. CONSTITUTION:In this coil spring 1, the diameter of the spring wire is smaller in the lower part below A-A' than in the upper part, and the spring is mostly covered with rubber bushes 2 below A-A'. A strut 3 is inserted through this spring 1, and supported by flanges 5 and 4 respectively in the upper and lower ends. Now, when a load is exerted onto the coil spring 1, at first, the lower part below A-A' with a smaller spring constant is mainly weighed down. As the load is gradually increased, bushes 2 are brought in contact with each other, and after that, the upper part above A-A' with a larger spring constant is weighed down, consequently obtaining a deflection characteristics as shown in the graph.
