The invention provides a novel large-preload auxiliary frame bushing, belongs to the technical field of auxiliary frame bushings, overcomes the technical defect that an existing auxiliary frame bushing structure is difficult to meet new performance requirements, and comprises an inner framework, the inner framework comprises an inner core with the interior in a hollow cylindrical shape and an outer plastic coating, the plastic coating and the inner core are connected into a whole, and the inner core and the plastic coating are connected into a whole. A longitudinal I-shaped symmetrical face is arranged outside the inner framework, an outer sleeve is arranged on the periphery of the inner framework, a square through hole is formed in the inner side of the inner framework, a pair of arc-shaped protruding blocks protruding inwards are arranged on the inner wall of the middle of the through hole, and a rubber sleeve is arranged between the outer sleeve and the inner framework. The product provided by the invention adopts the inner core and the I-shaped inner framework with a plastic-coated structure, so that the light weight requirement of the product is met; two parallel cavities are formed in the rubber sleeve in the outer sleeve, so that the technical requirement that the ratio of the hollow rigidity to the axial rigidity is consistent can be met; and the rough mounting connecting surface improves the internal bonding strength.
本发明提供的一种新型大预载副车架衬套属于副车架衬套技术领域,克服了现有副车架衬套结构难以满足新的性能要求的技术缺陷,包括内骨架,所述的内骨架包括内部呈空心圆柱状的内芯和外部的包塑,所述的包塑与内芯连为一体,其外部设有纵向的“工”字状对称面,所述的内骨架的外周设有外套管,其内侧设有方形的通孔,所述的通孔中部内壁上设有一对向内凸起呈圆弧状的凸块,所述的外套管与内骨架之间设有橡胶套,本发明产品采用内芯和包塑结构的“工”字状内骨架,满足了产品的轻量要求;外套管内部橡胶套内设有两个平行的空腔体,可实现空心刚度与轴向刚度比例一致的技术要求;粗糙的安装连接面,提高了内部之间的结合强度。
