Wheel loader center hinge limiting device
The invention provides a wheel loader center hinge limiting device, and relates to the technical field of wheel loaders, the wheel loader center hinge limiting device comprises a first front support, a first rear support, a second front support and a second rear support, the first front support is hinged to the first rear support through an upper hinge pin assembly, and the second front support is hinged to the second rear support through a lower hinge pin assembly; the second front support and the second rear support are hinged through a lower hinge pin assembly, the upper hinge pin assembly comprises an upper pin shaft and a first knuckle bearing, the upper pin shaft penetrates through the first front support and the first rear support, and the first knuckle bearing is arranged on the outer side of the upper pin shaft in a sleeving mode and installed on the first rear support; the first spacer bush and the second spacer bush are additionally arranged at the upper end and the lower end of the upper pin shaft and the two ends of the first knuckle bearing correspondingly and supported at the upper end and the lower end of the interval between the first rear support and the first front support, the axial gap of the upper pin shaft is adjusted and eliminated, the position of the first rear support is limited, impact force borne by the lower hinge pin assembly is shared, and abrasion is reduced.
本发明提供了一种轮式装载机中心铰接限位装置，涉及轮式装载机技术领域，包括第一前支座、第一后支座、第二前支座和第二后支座，所述第一前支座和第一后支座之间通过上铰接销组件铰接，所述第二前支座和第二后支座之间通过下铰接销组件铰接，所述上铰接销组件包括上销轴和第一关节轴承，所述上销轴贯穿第一前支座和第一后支座，所述第一关节轴承套在上销轴的外侧并与第一后支座安装；本发明在上销轴上的上下端、第一关节轴承的两端分别增加第一隔套和第二隔套，支撑在第一后支座和第一前支座之间间隔的上下端，调整、消除上销轴的轴向间隙，限定第一后支座的位置，分担下铰接销组件承载的冲击力，减少磨损。
