The lubrication structure between the choosing shaft and the cover of the gearbox includes the box cover, the choosing shaft, the skeleton oil seal, the choosing shaft positioning push block, the axle spring clamp and the dust cover. A step-type shaft hole is arranged on the cover. The choosing shaft is arranged in the small hole end of the shaft hole. The head and tail ends of the choosing shaft extend from the shaft hole. The skeleton oil seal, the choosing shaft positioning push block, the axle spring clamp and the dust cover are extended in the choosing shaft. Head end is arranged from inside to outside, skeleton oil seal is located in the big hole end of the shaft hole, skeleton oil seal is used to prevent oil leakage in the shaft hole, the positioning push block of the selection shaft is fitted with the end face of the shaft hole and skeleton oil seal, the positioning push block of the selection shaft is used to eliminate the axial movement of the selection shaft, the axle is clamped with the clamp spring and the end of the selection shaft head, and the axle is used to eliminate the axial movement of the positioning push block of the selection shaft. The inner end of the dust cover is clamped with the positioning push block of the shield shaft; the utility model eliminates two sealing rings of the original structure, and the shield shaft can obtain lubrication of oil in the gearbox, thus avoiding the rust and sticking of the shield shaft.
【技术实现步骤摘要】
选挡轴与变速箱箱盖之间的润滑结构
本技术属于车用选挡轴领域,尤其是一种选挡轴与变速箱箱盖之间的润滑结构。
技术介绍
原选挡轴为双“O型密封圈”结构密封方式,选挡轴在两个“O型密封圈”之间得不到变速箱油的持续润滑,渗水生锈,引起选挡卡滞、维修拆卸不便的问题。
技术实现思路
本技术提供一种选挡轴与变速箱箱盖之间的润滑结构,解决现有选挡轴不能持续润滑及易生锈的问题。为了解决上述技术问题,本技术的技术方案是:选挡轴与变速箱箱盖之间的润滑结构,包括箱盖、选挡轴、骨架油封、选挡轴定位推块、轴用卡簧、防尘罩,其特征在于:在箱盖上设有台阶式轴孔,选挡轴设置在轴孔的小孔端内,选挡轴的头尾两端均从轴孔内延伸出,骨架油封、选挡轴定位推块、轴用卡簧、防尘罩在选挡轴头端上从内至外依次设置,骨架油封限位在轴孔的大孔端内,骨架油封用于防止轴孔内的油液渗漏,选挡轴定位推块与轴孔、骨架油封的端面贴合,选挡轴定位推块用于消除选挡轴轴向窜动,轴用卡簧与选挡轴头端卡接,轴用卡簧用于消除选挡轴定位推块轴向窜动,防尘罩的内端与挡轴定位推块卡接。有益效果:本技术与现有技术相比,具有以下优点:1)取消了原结构的两个 ...
