The invention discloses a steering gear assembly capable of switching steering modes, a steering system and a vehicle, and the steering gear assembly comprises a first gear rack mechanism, a second gear rack mechanism and a third gear rack mechanism, the second gear rack mechanism comprises a second gear, a reversing gear and a second rack; the switching mechanism comprises a first connecting gear, a second connecting gear, a third connecting gear and a switching driving assembly; the first connecting gear is connected with the first gear, and the second connecting gear is connected with the second gear; the switching driving assembly is used for enabling the third connecting gear to be switched between the meshing position and the disengaging position in a reciprocating mode. At the meshing position, the first connecting gear and the second connecting gear are meshed with the third connecting gear; and in the disengagement position, the third connecting gear is not meshed with the first connecting gear and/or the second connecting gear. By means of the steering gear assembly, switching between independent steering and overall steering of a vehicle can be achieved, and stability, safety and reliability of overall steering can be guaranteed.
一种可切换转向方式的转向器总成、转向系统、车辆,转向器总成包括:第一齿轮齿条机构,包括:第一齿轮和第一齿条;第二齿轮齿条机构,包括:第二齿轮,换向齿轮和第二齿条;切换机构,包括:第一连接齿轮,第二连接齿轮,第三连接齿轮,以及切换驱动组件;第一连接齿轮与第一齿轮连接,第二连接齿轮与所述第二齿轮连接;切换驱动组件用于使第三连接齿轮在啮合位与脱离位之间往复切换;在啮合位,第一连接齿轮和第二连接齿轮均与第三连接齿轮啮合;在脱离位,第三连接齿轮不与第一连接齿轮和/或第二连接齿轮啮合。通过本转向器总成,不仅可实现车辆在独立转向与整体转向之间切换,还可能够保证整体转向的稳定性和安全可靠性。
