The invention discloses a sealing structure of a butt joint steering device, which comprises a pin shaft assembled at the side part of a frame. The connecting mechanism is used for connecting the pin shaft with a frame, the sealing mechanism is used for sealing the joint of the pin shaft and the frame, the filling mechanism is used for filling a gap between the sealing mechanism and the pin shaft, and the connecting mechanism is assembled in the middle of the pin shaft. The connecting mechanism and the sealing mechanism are matched, the pin shaft is installed on the vehicle frame through a connecting plate and a radial spherical plain bearing, the installation stability is high, the filling mechanism is arranged, when the vehicle frame is twisted, the sealing mechanism is arranged at the position where the pin shaft is connected with the vehicle frame, and the sealing mechanism is arranged at the position where the pin shaft is connected with the vehicle frame. The filling mechanism can fill the hinged position of the pin shaft and the frame to avoid a gap between the pin shaft and the frame, so that the sealing performance is ensured, and sand, dust and sludge are prevented from entering to influence the service life of the bearing.
本发明公开了一种较接转向设备的密封结构,包括销轴,所述销轴装配在车架的侧部,还包括用于将所述销轴与车架进行连接的连接机构、用于对所述销轴与车架连接处进行密封的密封机构以及用于对密封机构与所述销轴之间间隙进行填充的填充机构,连接机构装配在所述销轴的中部,密封机构布置在所述销轴与车架的连接处,填充机构配置在密封机构的周部,本发明的有益效果是设有连接机构与密封机构配合,通过连接板以及向心关节轴承将销轴安装在车架上,安装稳定性强,设有填充机构,当车架发生扭转时,填充机构会对销轴与车架的铰接位置进行填充以避免二者之间产生间隙,保证其密封性,防止沙尘污泥进入而影响轴承使用寿命。
