The invention provides a through shaft locking mechanism and a vehicle. The through shaft locking mechanism comprises a through shaft; the through shaft is sleeved with the bearing; the bearing seat is provided with a built-in locking cavity, the bearing seat is arranged outside the bearing in a sleeving mode, the output end of the through shaft penetrates through the bearing seat, and the bearing is contained in the built-in locking cavity; the outer ring locking nut is in threaded connection with the bearing seat and arranged outside the through shaft in a sleeving mode, the outer ring locking nut is contained in the built-in locking cavity and located between the bearing and the output end in the axial direction of the through shaft, and the outer ring locking nut is used for pre-tightening an outer ring of the bearing; and the locking washer is accommodated in the built-in locking cavity and is locked between the outer ring locking nut and the bearing seat. The outer ring locking nut for pre-tightening the outer ring of the bearing is arranged in the locking cavity of the bearing seat, and the locking washer is locked between the outer ring locking nut and the bearing seat, so that stepless adjustment can be realized, the working clearance of the bearing can be accurately controlled, and the risk of oil leakage caused by an external mode can be avoided.

    本发明提供一种贯通轴锁紧机构和车辆,贯通轴锁紧机构包括:贯通轴;轴承,套设于贯通轴外;轴承座,设置有内置锁紧腔,轴承座套设于轴承外,且贯通轴的输出端贯穿轴承座,轴承容纳于内置锁紧腔内;外圈锁紧螺母,和轴承座螺纹连接并套设于贯通轴外,外圈锁紧螺母容纳于内置锁紧腔内并沿贯通轴的轴向位于轴承和输出端之间,外圈锁紧螺母用于对轴承的外圈预紧;锁紧垫圈,容纳于内置锁紧腔内并锁紧于外圈锁紧螺母和轴承座之间。本发明通过将预紧轴承外圈的外圈锁紧螺母内置于轴承座的锁紧腔,并在外圈锁紧螺母和所述轴承座之间锁紧有锁紧垫圈,能实现无极调节,精确控制轴承的工作游隙的同时,还能避免外置方式漏油的风险。
