The electric power steering system can be roughly divided into six types according to the different positions of the motor and the differences in the deceleration mechanism: Tubular electric power steering system (C-EPS), single pinion electric power steering system (P-EPS), double pinion electric power steering system (DP-EPS), rack electric power steering system (R-EPS), wire electric power steering system and wheel-side electric power steering system. Among them, C-EPS, DP-EPS and R-EPS are widely used.
(1) C-EPS: cheap price, easy space layout, good working environment; However, the working noise of the motor is obviously transmitted, and it is not easy to achieve large power due to the bearing capacity of the gear, and the applicable model is compact and small car;
(2) DP-EPS: low noise, suitable price, fast power response speed, can achieve large power; However, the working environment of the motor is harsh, the sealing requirements are strict, and the space layout is difficult under the influence of the surrounding environment, and the applicable model is medium-sized and medium-sized and large car;
(3) R-EPS: low working noise, fast power response speed, can achieve greater power; However, the price is expensive, the structure of the deceleration mechanism is complex, and the space layout is difficult, and the applicable models are medium and large cars.
