The invention discloses a steering gear assembly and a vehicle. The steering gear assembly comprises an input shaft and an output shaft. The planetary gear mechanism comprises a sun gear, a planet gear and a gear ring, the planet gear is installed between the sun gear and the gear ring, the planet gear is provided with a planet shaft, the input shaft is in power connection with the planet shaft, the sun gear is in power connection with the output shaft, and the gear ring is sleeved with a worm gear; the motor assembly is in power connection with a worm, the worm is meshed with the worm gear, and the locking mechanism is used for selectively locking the worm. According to the steering gear assembly, the worm is selectively locked through the locking mechanism, when the worm is unlocked, the motor assembly can compensate the rotating angle of the steering wheel, and therefore the active steering function is achieved, and when the worm is locked, pure mechanical steering or steer-by-wire can be achieved in a more labor-saving mode.

    本发明公开了一种转向器总成和车辆,所述转向器总成包括:输入轴和输出轴;行星齿轮机构,所述行星齿轮机构包括太阳轮、行星轮和齿圈,所述行星轮安装于所述太阳轮和所述齿圈之间,所述行星轮设有行星轴,所述输入轴与所述行星轴动力连接,所述太阳轮与所述输出轴动力连接,所述齿圈外套设有蜗轮;电机组件和锁止机构,所述电机组件动力连接有蜗杆,所述蜗杆与所述蜗轮啮合,所述锁止机构用于对所述蜗杆选择性地锁止。根据本发明的转向器总成,利用锁止机构对蜗杆选择性地锁止,电机组件在蜗杆解锁时,可对方向盘的转角进行补偿,从而实现主动转向的功能,且在蜗杆锁止时,可更加省力地实现纯机械转向或线控转向。
