The invention relates to the technical field of steering machines, and particularly discloses a pressing device and a power-assisted steering system. The pressing device comprises an adjusting assembly and a pressing assembly, and the adjusting assembly limits the end, away from a transmission rod, of the pressing assembly; due to the fact that the bias pressure part is arranged between the adjusting assembly and the pressing assembly, the first bias pressure part applies bias pressure to the second bias pressure part, and the bias pressure enables the second bias pressure part to be close to the transmission rod. Therefore, the second bias pressure piece moves in the direction away from the adjusting assembly, and then the second bias pressure piece drives the pressing assembly to move in the direction close to the transmission rod. Thus the pressing assembly gives a pre-tightening force to the transmission rod, so that the transmission rod is always engaged with the transmission part in a pre-tightening manner. The device solves a series of problems of spring plastic deformation, spring rebound weakening, spring creep and the like in long-term use of the spring.

    本发明涉及转向机技术领域,具体公开了一种压紧装置及助力转向系统,该压紧装置包括调节组件和压紧组件,其中调节组件对压紧组件远离传动杆的一端进行限位;由于,偏压力件设于调节组件和压紧组件之间,第一偏压力件对第二偏压力件施加使第二偏压力件靠近传动杆的偏压力。所以,第二偏压力件沿远离调节组件的方向运动,进而第二偏压力件驱动压紧组件向靠近传动杆的方向运动。因此,压紧组件给予传动杆一个预紧力,使传动杆始终与传动件预紧啮合。该装置解决了弹簧在长期的使用中存在弹簧塑性变形、弹簧回弹消弱、弹簧蠕变等一系列问题。
