The invention relates to the technical field of steering wheel steering control, and discloses a steering axle assembly, a steering control system and a vehicle. In the steering axle assembly, an axle body comprises steering wheel mounting parts which are arranged at intervals; a steering oil cylinder is arranged on the axle body; a two-way oil pump is arranged on the axle body, a first oil port of the two-way oil pump is used for being communicated with one oil cavity of the steering oil cylinder, and a second oil port of the two-way oil pump is used for being communicated with the other oil cavity of the steering oil cylinder; and the oil pump motor is arranged on the axle body and connected with the two-way oil pump. The oil pump motor rotates forwards and backwards to drive the two-way oil pump to rotate forwards and backwards, so that a piston rod of the steering oil cylinder is driven to move to drive steering wheel supports installed on the steering wheel mounting parts to rotate, and steering of the steering wheels is achieved. Therefore, the steering axle assembly does not need to be supplied with oil through a hydraulic oil pump for providing hydraulic oil for a working system of the vehicle, so that the steering axle assembly can effectively reduce steering energy consumption, and is simple in structure and high in integration level.

    本发明涉及转向轮转向控制技术领域,公开一种转向桥总成、转向控制系统和车辆。转向桥总成中,桥体包括间隔布置的转向轮安装部;转向油缸设置在桥体上;双向油泵设置在桥体上,双向油泵的第一油口用于与转向油缸的一个油腔连通,双向油泵的第二油口用于与转向油缸的另一个油腔连通;油泵电机设置在桥体上并与双向油泵连接。油泵电机正反转则可以带动双向油泵正反转,从而驱动转向油缸的活塞杆移动以带动安装在转向轮安装部上的转向轮支架转动,从而实现转向轮的转向。这样,该转向桥总成就不需要通过向车辆的工作系统提供液压油的液压油泵来供油,因此该转向桥总成能够有效地降低转向能耗,并且结构简单,集成度高。
