Abstract

PURPOSE:To make the distribution of stress uniform and reduce the weight of material, by providing an auxiliary leaf spring, which constitutes a piled leaf spring, with a tapered portion whose thickness decreases gradually toward the tip of the auxiliary leaf spring. CONSTITUTION:Main leaf springs 1 have tapered portions 6,... whose thickness decreases gradually toward the tips of the main leaf springs 1. The effective lengths of the main leaf springs 1 are made almost equal to each other. The main leaf springs 1 have a looped portion 7 and a wound portion 8 at the tips of the main leaf springs 1. An auxiliary leaf spring 10 comprises a tapered portion 12 whose thickness decreases toward the tip of the auxiliary leaf spring 10 and an arc-shaped portion 13 protruded toward the tension side. The effective length of the auxiliary leaf spring 10 is made almost equal to that of the main leaf springs 1. The arc-shaped portion 13 is supported so that it can come into and out of contact with the main leaf spring 1. The tapered portion 12 is kept out of contact with the main leaf spring 1. When load P is lower than a predetermined value Po, only the main leaf springs 1 act. When the load P is higher than the value Po, the main leaf spring 1 comes into contact with the arc-shaped portion 13 of the auxiliary leaf spring 10 so that the auxiliary lead spring 10 acts together with the main leaf springs 1. When the load P is equal to the value Po, the action of the leaf springs 1, 10 changes discontinuously. This results in improving the stability of a vehicle both in the unloaded state and in the loaded state.
