The invention relates to an independent suspension ball head assembly for a new energy passenger car and a machining method of the independent suspension ball head assembly, and belongs to the technical field of independent suspension structures.The independent suspension ball head assembly comprises a ball head shell, a ball head pin is arranged on the ball head shell, and the ball head pin and the ball head shell are clamped and limited in an inserted and embedded mode; the lower end of the ball head shell is provided with a sealing cover plate connected with the ball head shell in a clamped and embedded mode, the upper end of the ball head shell is provided with a plurality of clamping rings connected with the ball head shell in a sleeved mode, and a dustproof sealing ring connected with the ball head pin in a sleeved mode is arranged between the clamping rings and the ball head shell. And a built-in hoop is arranged between the upper end of the dustproof sealing ring and the ball pin. The sealing device has the characteristics of compact structure, good sealing effect and long service life. After the surface of the ball stud is treated, the neutral salt spray test is performed, and the problem that the ball stud is poor in corrosion resistance is solved.

    本发明涉及一种用于新能源乘用车的独立悬挂球头总成及其加工方法,所属独立悬挂结构技术领域,包括球头壳体,所述的球头壳体上设有与球头壳体相插嵌式卡接限位的球头销,所述的球头壳体下端设有与球头壳体相卡嵌式嵌套连接的密封盖板,所述的球头壳体上端设有若干与球头壳体相套接的卡圈,所述的卡圈与球头壳体间设有与球头销相套接的防尘密封圈,所述的防尘密封圈上端与球头销间设有内置卡箍。具有结构紧凑、密封效果好和使用寿命长的特点。对球头销表面处理后并进行中性盐雾试验,解决了球头销防腐能力差的问题。
