The utility model has the advantages of anti shedding heavy vehicle plate pin mounting structure, including plate, pin and lug seat; the steel pin comprises a pin shaft and a rectangular flange, the flange forming rectangular flange shaft steel pin in the pin end end through pin welding steps, in the four corners of the rectangular flange is provided with a connecting through hole; the lug seat for door shaped structure on both sides of the lug plate staggered on two steel pin hole, in which a lug plate lateral plate pin through hole is arranged at the four corners of the plum blossom shaped boss, set in a plum blossom shaped boss with four rectangular flange through screw hole hole matched with the pin diameter; the pin hole is matched with the outer diameter and the outer diameter of steel plate; the pin shaft lug connecting shaft is matched with the outer diameter. The utility model has the beneficial effects is through the bolt flange plate will be rectangular pin and lug block fastening together, to avoid the steel pin lug pin hole seat on the impact of preventing lug block damage and falling plate pin, eliminating the security risks.
【技术实现步骤摘要】
本技术涉及到重型汽车纵置钢板弹簧安装
,特别涉及到一种防脱落重型汽车钢板销安装结构。
技术介绍
现有技术重型汽车普遍采用纵置钢板弹簧悬架,而其钢板弹簧的安装离不开钢板销。钢板销不仅承受垂直载荷,还承受制动力与力矩,有的还承受驱动力。如果汽车行驶中发生钢板销脱落,则会引起车轴车轮脱落,形成严重的安全事故。现在有技术纵置钢板弹簧安装结构是在吊耳座上的钢板销孔开槽,通过螺栓锁紧销孔变形形成过盈配合抱住钢板销轴。从技术角度将,这是一种很有效的钢板销锁紧方式。但是,由于实际销孔直径和钢板销轴的尺寸偏差等因素,销孔不能形成过盈配合,孔无法抱紧轴。在实际使用中,吊耳座的销孔被钢板销的冲击载荷冲击成条形孔,导致锁紧失效,钢板销脱出,严重影响行车安全,甚至造成恶劣影响。另外,有的吊耳座由于结构、强度及加工工艺的限制,未采用上述传统的防脱落结构。显然,现有技术纵置钢板弹簧安装结构存在着吊耳座销孔易被钢板销冲击成条形孔,导致锁紧失效,钢板销脱出,存在安全隐患等问题。
