Abstract
The invention belongs to the technical field of automobile steel plate spring suspension systems, and particularly discloses a large-tonnage balanced suspension support installed on the inner side of a frame. The support comprises a support body. A large end face is arranged at the upper end of the support body and provided with a support bolt hole set connected with a longitudinal beam of the frame. The rear portion of the large end face extends outwards to form an arc-shaped shell stand for connecting V-shaped thrust rods on a front axle and a rear axle. A horizontal bracket connected with a transverse beam of the frame and integrated with the support body is arranged below the stand. A balance shaft hole is formed in the lower portion of the horizontal bracket. A lower connecting plate bolt hole set connected with a lower connecting plate is formed in the lower end of the support body. The large-tonnage balanced suspension support is simple in structure; by combining an L-shaped steel plate of the transverse beam with the support to form the horizontal bracket and converting all blind hole threaded holes in the support into through hole threaded holes, the large-tonnage balanced suspension support is simple and novel in structure, light in weight, low in cost, high in product universality, high in bolt connection reliability and suitable for mass production.
