The invention discloses an air suspension guide arm with a lateral bend and a connecting structure of the air suspension guide arm and an axle, belongs to the technical field of special vehicles, and designs an arc-shaped guide arm to effectively overcome the technical defects of a Z-shaped guide arm. The anti-rolling sections are arranged on the two sides of the arc shape, the axle bearing bush is designed to be matched with the anti-rolling sections of the guide arm, relative rotation of the arc-shaped guide arm and the axle pipe can be completely eradicated, the strength of the arc-shaped guide arm is improved, and the service life of the arc-shaped guide arm is prolonged. Small double-row positioning key grooves are formed in the arc-shaped bottom and are used for precise positioning adaptation, so that the guide arm and the axle bearing bush are precisely centered, and stress is more uniform; a smooth transition part is designed at the arc-shaped rear part, so that the suitability is improved; lateral bending structures are designed at the tail ends of the arc-shaped guide arms and can be well matched with the gravity center of the airbag, the airbag is prevented from being damaged, the service life of the airbag is effectively prolonged, and the vehicle body weight is reduced. Compared with an arc-shaped guide arm in the prior art, the service life of the guide arm is prolonged by at least 50%, and major hidden dangers such as safety accidents caused by low strength of the guide arm are solved.

    一种带侧弯的空气悬挂导向臂及与车桥的连接结构,所属专用车技术领域,本发明设计弧形导向臂,有效解决“Z”字型导向臂存在的技术缺陷;在弧形两侧设置防滚段,并设计车桥轴瓦与导向臂防滚段适配,能够完全杜绝弧形导向臂与车桥管的相对转动,提高弧形导向臂的强度和使用寿命;并在弧形底部开设较小的双排定位键槽,用于精准定位适配,使导向臂与车桥轴瓦精准对中受力更均匀;在弧形后部设计平滑过度部位,提高适配性;在弧形导向臂尾端设计侧弯结构,能够很好的与气囊重心适配,防止气囊损坏,有效提高气囊使用寿命,减少车身重量。与现有技术弧形导向臂相比,本发明导向臂至少延长使用寿命50%,解决导向臂强度低发生安全事故等重大隐患。
