The invention discloses an articulation mechanism of a folding lumbar steering tractor, which comprises a front articulation seat, an articulated outer drum, an articulation connection assembly and an inner drum. The Front Articulation seat is provided with an upper front articulation ear and a lower front articulation ear. The front end of the articulated outer drum is provided with an upper articulation ear and a lower articulation ear, and the front articulation seat is articulated through the articulation. The connection assembly articulates the upper front hinge ear with the upper drum articulated ear, and the lower front hinge ear with the lower drum articulated ear, thus enabling the front hinge seat to articulate with the articulated outer drum. The inner drum is sleeved in the articulated outer drum. The front and rear ends of the inner drum are respectively provided with bushes, and the inner drum and the articulated outer drum are separated by bushes. A roller connecting end cover and a limiting clamping spring are arranged at the front end of the inner roller. The invention adopts two sets of articulated connection assemblies to articulate the front articulated seat and the articulated outer drum, so that the bending and turning are smooth and the work is stable and reliable. The bushing is used as the articulated outer drum and the inner drum to withstand wear and tear. The installation is simple, the replacement is convenient and the cost is low.

一种折腰转向拖拉机的铰接机构
本专利技术涉及一种折腰转向拖拉机的铰接机构,属于农业机械拖拉机的连接机构制备
技术介绍
折腰转向拖拉机由于转弯半径小、轻便灵活、越野能力强的特点具有广阔的市场空间,而折腰转向拖拉机的铰接机构性能决定了产品的安全性和可靠性。目前市场上折腰转向拖拉机的铰接机构设计中,铰接点普遍采用单一的销轴形式,滚筒采用全钢材料,容易引起滚筒磨损快,寿命周期短,更换费用高等问题。而且铰接点转动不顺畅,整体安装难度大,维护成本高。因此,提供一种拖拉机的铰接机构,对于提高折腰转向拖拉机的转向顺畅性,降低成本,特别是维护成本有着现实的意义。
技术实现思路
本专利技术的目的是提供一种折腰转向拖拉机的铰接机构,以衬套作为滚筒结构承受磨损,安装简单,更换方便,维护成本低;以关节轴承作为铰接点主要转动部件,实现折腰转动顺畅,工作稳定可靠。克服传统铰接机构安装难度大,维护成本高的不足。为解决上述问题,本专利技术采用以下技术方案:一种折腰转向拖拉机的铰接机构,包括前铰接座、铰接外滚筒、铰接连接总成和内滚筒,前铰接座上设置有上前铰接耳和下前铰接耳,铰接外滾筒的前端设置有上滾筒铰接耳和下滾筒铰接耳,前铰接座通过铰接连接总成将上前铰接耳与上滾筒铰接耳铰接,将下前铰接耳与下滾筒铰接耳铰接,从而也使得前铰接座与铰接外滾筒铰接,内滚筒套入铰接外滚筒内,内滚筒的前端与后端分别设置有衬套,内滚筒与铰接外滚筒之间由衬套隔开,内滚筒前端设置有滾筒连接端盖和限位卡簧。所述的铰接连接总成包括:连接销轴、密封圈、关节轴承、O型圈、垫圈、压紧垫圈和圆螺母。所述的前铰接座与拖拉机的前部连 ...
