Abstract: Aiming at the problems such as complex structure and low power transmission efficiency existing in the traditional high-pressure air supply system of vehicle air suspension,structurally integrated sliding vane electric air pump technology is proposed. By integrating the drive motor and the sliding vane air pump in the design,the direct conversion of electrical energy into pneumatic energy is realized,thus forming a new type of efficient and compact electric air pump. The modeling and kinematic characterization of the implicated motion of the articulated sliding vane has been carried out by means of the ADAMS software platform. The results show that,the articulated sliding vane′s centroid exhibits simple harmonic motion in radial displacement variation,tracing an elliptical trajectory. Its velocity and acceleration demonstrate sinusoidal variation patterns,with particularly pronounced fluctuations during the initial phase. Optimizing the spherical joint dimensions of the articulated sliding vane and the distance between the sliding vane′s spherical joint and the pump outer rotor center improves system performance. Under steady-state motor operation,the 1.7 mm spherical joint radius reduces angular acceleration by 60.00 % compared to the 1.6 mm baseline,while a radius of 1.8 mm achieves a 99.97 % reduction. Within the selectable range,a larger spherical joint of the articulated sliding vane increases the stability of the implicated motion system. A greater distance between the articulated sliding vane′s spherical joint and the pump outer rotor center enhances motion stability within its allowable range.
