Abstract

An auxiliary plate spring support comprises a support body (1) and a limiting retainer (2). Connecting holes (3) are arranged on the lower portion of the support body (1), a circular arc curved surface on the lower portion of the limiting retainer (2) is a supporting curved surface contacting with an auxiliary plate spring (9), the supporting curved surface is formed by connecting a circular arc curved surface I (4), a circular arc curved surface II (5) and a circular arc curved surface III (6), circular arc centers of the circular arc curved surface I (4) and the circular arc curved surface III (6) deviate from a symmetric center surface of the auxiliary plate spring support, the radius of the circular arc curved surface I (4) is equal to that of the circular arc curved surface III (6), the circular arc curved surface I (4) and the circular arc curved surface III (6) are symmetric relatively to the symmetric center surface of the auxiliary plate spring support, a slant angle alpha of the circular arc curved surface I (4) is equal to a slant angle beta of the circular arc curved surface III (6) and equal to a fully-loaded slant angle delta of the auxiliary plate spring (9), and the circular arc center of the circular arc curved surface II (5) is positioned on the symmetric center surface of the auxiliary plate spring support. By the auxiliary plate spring support, hole position standardization is realized.

Description

technical field [0001] The invention relates to a structural design of an auxiliary leaf spring bracket of an automobile leaf spring, more specifically relates to an auxiliary leaf spring bracket, and belongs to the technical field of truck suspension systems. Background technique [0002] The existing single rear axle of trucks has a large change in axle load from no-load to full-load. Generally, the rear suspension adopts the main plate spring + auxiliary leaf spring configuration; the current typical main and auxiliary leaf spring structure, the auxiliary leaf spring is arranged above the main plate spring, An auxiliary leaf spring support is arranged above the two ends of the auxiliary leaf spring, and the auxiliary leaf spring support is fixed on the longitudinal beam of the vehicle frame; the above-mentioned structure has simple process, mature design method and strong versatility, and is adopted by most automobile manufacturers. When the axle load of the rear axle is ...
