The invention discloses a power-assisted steering system, a power-assisted steering method and application of the power-assisted steering system and the power-assisted steering method in a hydraulic carrier, and relates to the field of power-assisted steering systems. The transmission ratio between the transmission part and the transmission wheel set can be adjusted by adjusting the transmission radius of the transmission wheel set, so that the hydraulic pressure output by the hydraulic pump is adjusted, then the steering assisting power output by the hydraulic power assisting assembly is adjusted, and the hydraulic power assisting system provides proper steering assisting power for vehicle steering; the power-assisted effect of the power-assisted steering system and the driving experience of the vehicle can be improved; when the load of the vehicle is increased, the transmission radius of the transmission wheel set is directly and correspondingly adjusted through the cooperation of the chassis which is extruded to move downwards and the telescopic adjusting assembly so as to adjust the magnitude of the power-assisted steering, and the power-assisted steering does not need to be manually and correspondingly adjusted according to the magnitude of the load of the vehicle; and the adjustment process of the power-assisted steering is more convenient and quicker.

    本发明公开了一种转向助力系统、转向助力方法及其在液压搬运车中的应用,涉及转向助力系统领域。本发明通过调节传动轮组的传动半径,能调节传动件与传动轮组之间的传动比,从而调节液压泵输出的液压力大小,进而调节液压助力组件输出的转向助力的大小,使得液压助力系统为车辆转向提供适宜的转向助力,能提高转向助力系统的助力效果和车辆的驾驶体验;且是在车辆的负载增加时,通过被挤压下行的底盘和伸缩调节组件的配合直接对传动轮组的传动半径进行相应调整,以调节转向助力的大小,而无需人工根据车辆负载的大小来对转向助力进行相应调整,使得转向助力的调节过程更加方便快捷。
