A gearbox assembly for a power take-off from an electric motor of an electric power assisted steering apparatus, the gearbox assembly comprising: a gearbox housing; a main bearing assembly; a tail bearing assembly; a piston; the invention relates to a gearbox assembly comprising a piston having a bore, and a spring, characterized in that the piston has a conical shoulder located within the bore, the diameter of which increases from the end farthest from the motor towards the end closest to the motor, and in that the gearbox assembly further comprises an annular o-ring seated on the conical shoulder, the spring acting on the piston through the o-ring, as a result, movement of the worm shaft towards the motor shaft compresses the spring, which in turn drives the o-ring along the tapered shoulder until the o-ring becomes wedge-shaped between the piston and the inner wall of the bore of the worm shaft.

    一种用于来自电动动力辅助转向设备的电动马达的动力输出件的齿轮箱组件,该齿轮箱组件包括:齿轮箱壳体;主轴承组件;尾轴承组件;活塞;以及弹簧,其特征在于,活塞具有位于孔内的锥形肩部,该锥形肩部的直径从最远离马达的端部朝向最靠近马达的端部增加,并且该齿轮箱组件进一步包括环形o形环状件,该环形o形环状件坐置在锥形肩部上,弹簧通过o形环状件作用于活塞上,由此蜗杆轴朝向马达轴的移动使弹簧压缩,这进而又沿着锥形肩部驱动o形环状件,直到o形环状件在活塞与蜗杆轴的孔的内壁之间变成楔形为止。
