The invention provides a differential wheel and a trolley, the differential wheel comprises a wheel, a gear cavity is formed in the side face of the wheel, and a main gear and one or more auxiliary gears meshed with the main gear are placed in the gear cavity; the gear cavity is provided with a limiting part, the auxiliary gear is limited by the limiting part, and the main gear drives the wheels to rotate at the same speed through the auxiliary gear. When the rotating speed of the main gear is different from the rotating speed of the wheel, the auxiliary gear generates displacement in the gear cavity, the auxiliary gear is separated from the limiting part, and the main gear drives the auxiliary gear to idle. During normal walking, the main gear drives the wheels to rotate through the auxiliary gear, and once the rotating speed of the main gear is different from that of the wheels due to turning, the auxiliary gear is separated from the limiting part so that the auxiliary gear can idle, and differential operation is achieved.
本发明提供一种差速轮及小车,差速轮包括车轮,所述车轮侧面开设有齿轮腔,所述齿轮腔内放置有主齿轮和一个或多个与所述主齿轮啮合的副齿轮;所述齿轮腔具有限位部,所述副齿轮被所述限位部限位,所述主齿轮通过副齿轮驱动所述车轮同速转动;当主齿轮转速与所述车轮转速不同时,所述副齿轮在齿轮腔内产生位移,所述副齿轮与所述限位部分离,所述主齿轮驱动所述副齿轮空转。在正常行走时主齿轮通过副齿轮驱动车轮转动,一旦过弯导致主齿轮转速与车轮转速不同时,副齿轮与限位部分离使得副齿轮得以空转,实现差速运转。
