The invention relates to a rear torsion beam bushing. The rear torsion beam bushing comprises a gluing piece, an elastic limiting block and a limiting plate, the gluing piece is formed by vulcanizingan inner metal framework, a rubber body and an outer metal framework, and the outer metal framework is arranged on the outer side of the inner metal framework in a sleeving mode and is coaxial with the inner metal framework; and a first supporting lug and a second supporting lug are arranged at the ends of the two sides, in the axial direction, of the inner metal framework correspondingly. A concave cavity is formed in the upper end of the rubber body, the elastic limiting block is embedded in the concave cavity, and the limiting plate is fixedly arranged on the inner metal framework above therubber body in a sleeving mode. The inner sleeve is of an integral structure, and the elastic limiting block and the metal limiting plate are assembled in the gluing piece, so that the high rigidityrequirement is not lost in the aspect of operation stability, the required X-direction and torsion characteristic requirements are not spent in the aspect of comfort, abuse working condition protection is provided in the Y direction of the whole automobile, and comfortable NVH performance and reliable fatigue durability are achieved.

    本发明涉及一种后扭力梁衬套,包括胶合件、弹性限位块、限位板,所述胶合件由内金属骨架、橡胶体、外金属骨架硫化而成,所述外金属骨架套设于内金属骨架的外侧,且与内金属骨架同轴;所述内金属骨架沿轴向的两侧端部上分别设有第一支耳和第二支耳;所述橡胶体的上端设有凹腔,所述弹性限位块嵌设于凹腔中,所述限位板固定套设于橡胶体上方的内金属骨架上;本发明内套采用是整体式结构,且胶合件内部装配弹性限位块及金属限位板,因此在操稳性方面不失高刚度要求,在舒适性方面又不乏所需X向及扭转特性要求,在整车Y向提供滥用工况防护,实现舒适的NVH性能及可靠的疲劳耐久性。
