The invention discloses a rigidity-adjustable non-pneumatic tire which sequentially comprises a rim, honeycomb spokes, an inner side steel thin film ring, a magneto-rheological elastic annular beam, an outer side steel thin film ring, a rubber tread, a controller and a plurality of strain gauge sensors. The light coil assembly is connected to a slip ring rotor arranged on a wheel axle through a wire, a slip ring stator is connected with a controller through a wire, the multiple strain gauge sensors are symmetrically arranged on the side face of the magnetorheological elastic annular beam with the wheel as the center, and the circumferential distances are equal. The multiple strain gauge sensors and the light coil assembly are electrically connected with the controller through wires. Targeted power supply is carried out on the coils in the contact area of the non-pneumatic tire and the road surface, the local material characteristics of the magneto-rheological annular beam are changed, then the lateral deviation and longitudinal sliding rigidity are regulated and controlled, the requirements of a vehicle for the control performance and the braking safety performance under different working conditions can be met, pure sideslip can be effectively avoided when the vehicle runs at a high speed, and the service life of the vehicle is prolonged. And the control and safety are improved.
本发明公开了一种刚度可调控的非充气轮胎,依次包括轮辋、蜂窝辐条、内侧钢制薄膜环、磁流变弹性环形梁、外侧钢制薄膜环、橡胶胎面、控制器、多个应变片传感器,所述磁流变弹性环形梁内部嵌入有轻质线圈组,所述轻质线圈组通过导线连接在设置于轮轴上的滑环转子,滑环定子通过导线连接控制器,多个所述应变片传感器关于车轮中心对称布置于磁流变弹性环形梁侧面,且周向间距相等,多个应变片传感器、轻质线圈组均通过导线与控制器电性连接。本发明通过对非充气轮胎与路面接触区域内的线圈靶向供电,改变磁流变环形梁局部材料特性,进而调控侧偏与纵滑刚度,可以满足不同工况下,车辆对操控性能和制动安全性能的要求,车辆高速行驶时可有效避免纯侧滑,提升操控和安全性。
