Abstract

An auxiliary plate spring sliding plate comprises a sliding plate main body (1), wherein a contact plane surface (3) is arranged on the upper surface of the sliding plate main body (1), a threaded hole (4) is formed in the contact plane surface (3), the circular arc curved surface at the lower part of the sliding plate main body (1) is a supporting curved surface in contact with an auxiliary plate spring (10), the supporting curved surface is formed by connecting a circular arc curved surface I (5), a circular arc curved surface II (6) and a circular arc curved surface III (7), the circular arc centers of the circular arc curved surface I (5) and the circular arc curved surface III (7) are deviated from the symmetric center surface of the auxiliary plate spring sliding plate, the radius of the circular arc curved surface I (5) is equal to that of the circular arc curved surface III (7), the circular arc curved surface I (5)and the circular arc curved surface III (7) are symmetric relative to the symmetric centre of the auxiliary plate spring sliding plate, the inclined angle Alpha of the circular arc curved surface I (5) is equal to the inclined angle Beta of the circular arc curved surface III (7) and is equal to the full load inclined angle Delta of the auxiliary plate spring (10), and the circular arc center of the circular arc curved surface II (6) is position on the symmetric centre surface of the auxiliary plate spring. Hole-site standardization is realized.

Description

technical field [0001] The invention relates to a structural design of an auxiliary leaf spring sliding plate of an automobile leaf spring, more specifically relates to an auxiliary leaf spring sliding plate, and belongs to the technical field of truck suspension systems. Background technique [0002] The axle load of the existing single rear axle of the truck varies greatly from no-load to full-load, and the rear suspension generally adopts the main plate spring + auxiliary leaf spring configuration; the existing main and auxiliary leaf spring structure, the auxiliary leaf spring is arranged above the main plate spring, There are auxiliary leaf spring sliders above the two ends of the auxiliary leaf spring, the auxiliary leaf spring slider is fixed on the auxiliary leaf spring bracket, and the auxiliary leaf spring bracket is fixed on the frame longitudinal beam; the above structure has simple process, mature design method, and strong versatility. Used by most car manufactu...
