Abstract
The invention discloses a retarding mechanism. The retarding mechanism comprises a steering shaft, a torsion bar, an electromotor, a clutch, a worm and a worm wheel, wherein the torsion bar is arranged in the steering shaft, the worm wheel is sleeved at the outer side of the steering shaft, the worm is arranged at the left side of the worm wheel, the clutch is arranged at the left side of the worm, and the electromotor is arranged at the left side of the clutch. According to the retarding mechanism, the torque of the electromotor is acted onto the steering shaft through the engaged transmission of the worm wheel and the worm by connecting the worm with the electromotor, so as to realize the power-assisted steering, the retarding mechanism is stable and reliable to work, accurate and low-cost, and when the electromotor does not work, the clutch can automatically separate.
