(EN) The utility model relates to a wheel pushing device. The wheel pushing device comprises a fixed seat; two groups of pushing assemblies are arranged at intervals, and the pushing assemblies are connected with the fixed seat in a sliding manner; the rotating shaft is located between the two pushing assemblies, and the rotating shaft is rotationally connected with the fixing seat; the middle part ofthe connecting block is fixed on the rotating shaft; the number of the connecting rods is two, the two connecting rods correspond to the two pushing assemblies, one ends of the two connecting rods arerotationally connected with the two ends of the connecting block respectively, and the other ends of the two connecting rods are rotationally connected with the two pushing assemblies; and the linearmotion power device is fixed on the fixed seat, and an output shaft of the linear motion power device is connected with one group of pushing assemblies. After the scheme is adopted, only one power device is needed, and the manufacturing cost is reduced.
(ZH) 本实用新型涉及一种车轮推动装置，包括：固定座；推动组件，推动组件间隔设置有两组，且推动组件和固定座滑动连接；转轴，转轴位于两组推动组件之间，且转轴和固定座转动连接；连接块，连接块的中部固定在转轴上；连杆，连杆设置有两个，两个连杆和两组推动组件对应设置，两个连杆的一端分别和连接块的两端转动连接，两个连杆的另一端和两个推动组件转动连接；直线运动动力装置，直线运动动力装置固定在固定座上，且直线运动动力装置的输出轴和其中一组推动组件连接。采用这样的方案后，仅需一个动力装置，降低制造成本。
