The invention belongs to the technical field of amphibious vehicles, and particularly relates to an amphibious wheel type vehicle steering pull rod sealing device which comprises a corrugated rubber sleeve, a metal pressing plate, a sealing paper pad and a fixing bolt. One end of the corrugated rubber sleeve is fastened to a steering main pull rod, and the other end of the corrugated rubber sleeveis pressed and sealed through the metal pressing plate and the sealing paper pad in a flange mode and fixed to a vehicle body. The corrugated rubber sleeve has a telescopic function and can meet therequirement for left-right movement displacement of the steering main pull rod during left-right steering of a vehicle. The problem of cabin penetrating sealing of the steering pull rod of the amphibious vehicle is solved, the steering pull rod is arranged in the vehicle, and increase of vehicle water resistance caused by vehicle bottom line type damage due to pull rod external arrangement is avoided. The amphibious wheel type vehicle steering pull rod sealing device is simple in structure, light in weight, good in applicability and capable of completely meeting the sealing requirement of theamphibious wheel type vehicle steering pull rod.
本发明属于水陆轮式两栖车辆技术领域,具体涉及一种水陆轮式两栖车转向拉杆密封装置。该密封装置包括波纹胶套、金属压板、密封纸垫、以及固定螺栓。波纹胶套一端紧固在转向主拉杆上,另一端以法兰的型式,通过金属压板、密封纸垫压紧密封,固定在车体上。波纹套具有伸缩功能,满足车辆左右转向时主拉杆的左右移动位移要求。本发明解决了水陆轮式两栖车转向拉杆穿舱密封问题,转向拉杆布置在车内,避免拉杆车外布置导致车底线型破坏带来车辆水上阻力的增大。该水陆轮式两栖车转向拉杆密封装置结构简单、重量轻、适用性好,能够完全满足水陆轮式两栖车转向拉杆的密封要求。
