摘要:
A leaf spring suspension assembly includes a leaf spring assembly having a plurality of vertically stacked leaf springs and a bearing assembly positioned adjacent an end thereof. The bearing assembly includes an upper insulator cup having an upper recess and a lower bracket cap having a lower recess and upper and lower bonded bearings. The upper bonded bearing is received in the upper recess and includes a rigid lower member having an upper elastomer element bonded thereto; the bearing being received adjacent the upper side of the leaf spring assembly. The lower bonded bearing is received in the lower recess and includes a rigid upper member having a lower elastomer element bonded thereto; the lower bearing being received adjacent the lower side of the leaf spring assembly. At least one of the upper and lower elastomer elements includes a spherical elastomer element. An adjuster may be provided for selectively adjusting and securing the relative position between the leaf spring assembly and the bearing assembly.
