The invention relates to the technical field of vehicle cleaning, and discloses an automatic car washer. A plurality of ball grooves are annularly formed in an output shaft in the circumferential direction of the output shaft, each ball groove comprises an outer opening formed in the outer wall of the output shaft and an inner opening communicated with an inserting groove, limiting balls are contained in the ball grooves, the sizes of the outer openings and the inner openings are smaller than the ball diameters of the limiting balls, and annular clamping grooves for clamping the spherical surfaces of the limiting balls are annularly formed in the outer circumferential surface of a connecting shaft; and the output shaft is sleeved with a movable sleeve to press the limiting balls into the annular clamping groove. The limiting balls can move in the ball grooves, when the movable sleeve connected to the output shaft in a sleeving mode slides to the position covering the outer openings ofthe ball grooves, And the inner wall of the movable sleeve can squeeze the limiting balls inwards to make the spherical surfaces of the limiting balls clamped into the annular clamping groove, so theaxial position of the connecting shaft in the inserting groove is limited, and the connecting shaft cannot be separated from the output shaft in the process that a driving motor drives wheel brushes to operate, thereby the stability of the wheel brushes in the operation process is guaranteed.

    本发明涉及车辆清洗技术领域,公开一种自动洗车机,输出轴沿其圆周方向环设若干球槽,球槽包括开设于输出轴外壁的外开口及连通于插槽的内开口,球槽内容置有限位球,外开口与内开口的尺寸均小于限位球的球径,连接轴的外周面环设有供限位球的球面卡接的环形卡槽;输出轴上套设有活动套筒以将限位球压合于环形卡槽内,本发明的一种自动洗车机,限位球能够于球槽内进行活动,当套接于输出轴上的活动套筒滑移至覆盖球槽外开口位置时,活动套筒的内壁能够将限位球向内挤压,以使限位球的球面卡接至环形卡槽内,从而限定连接轴于插槽内的轴向位置,使得驱动电机在驱动轮刷运行的过程中,连接轴无法从输出轴脱离,从而保证轮刷运行过程中的稳定性。
