The invention relates to a screw rod, a telescopic mechanism, a synchronous telescopic mechanism, a steering column assembly and a vehicle. The synchronous telescopic mechanism comprises a plurality of driving gears, driving screw rods and a connecting part, and the driving screw rods and the driving gears are in one-to-one correspondence and are synchronously and rotationally connected; the multiple connecting parts are in one-to-one correspondence with the driving screws and can be connected with the driving screws in a relatively rotating mode, and the multiple driving gears synchronously drive the screws to rotate so that the synchronous telescopic mechanism can drive the steering column to stretch out and draw back synchronously; wherein the plurality of driving gears comprise a first driving gear, the plurality of connecting parts comprise a first tubular column connecting part, the plurality of driving screws comprise first screws connected with the first driving gear and the first tubular column connecting part, the first screws are in threaded fit with the first tubular column connecting part, and the first screws are configured to be capable of being driven by the first driving gear to rotate; therefore, the storage speed of the steering column during large-stroke stretching and retracting is effectively increased, the NVH performance is better, and the cost is lower.
本公开涉及一种螺杆、伸缩机构、同步伸缩机构、转向管柱总成及车辆,该同步伸缩机构包括多个驱动齿轮、驱动螺杆以及连接部,多个驱动螺杆与驱动齿轮一一对应且同步转动地连接;多个连接部与驱动螺杆一一对应且可相对转动地连接,多个驱动齿轮同步驱动螺杆转动能够使得同步伸缩机构带动转向管柱同步伸缩;其中多个驱动齿轮包括第一驱动齿轮,多个连接部包括第一管柱连接部,多个驱动螺杆包括与第一驱动齿轮和第一管柱连接部连接的第一螺杆,第一螺杆与第一管柱连接部螺纹配合,第一螺杆构造为能够由第一驱动齿轮驱动转动,还能够相对于第一驱动齿轮轴向移动,如此有效地提高转向管柱在大行程伸缩时的收纳速度,并且NVH性能更好且成本更低。
