The invention provides a rolling ball ramp structure, an electric control brake and a vehicle, and relates to the technical field of brakes, the rolling ball ramp structure comprises a driving side rotor, a driven side rotor and a plurality of rolling balls, and the driving side rotor comprises a plurality of driving side ramp grooves; the driven side rotor comprises a plurality of driven side ramp grooves, and accommodating cavities are formed between the driven side ramp grooves and the corresponding driving side ramp grooves; the multiple rolling balls are arranged in the containing cavities correspondingly, the rolling balls abut against the inner walls of the two sides of the driving side ramp groove correspondingly and/or the rolling balls abut against the inner walls of the two sides of the driven side ramp groove correspondingly, and the rolling balls can move along the driven side ramp groove under relative rotation driving of the driving side rotor and the driven side rotor. And then the driving side rotor and the driven side rotor are driven to relatively move along the axial direction. Two-point contact is formed between the rolling balls and the inner walls of the two sides of the ramp groove, so that the Hertz contact stress can be reduced, and the service life of the rolling balls is prolonged.

    本发明提供了一种滚球坡道结构、电控制动器以及车辆,涉及制动器技术领域,包括驱动侧转子、被驱动侧转子和多个滚球,驱动侧转子包括多个驱动侧坡道槽;被驱动侧转子包括多个被驱动侧坡道槽,被驱动侧坡道槽与对应的驱动侧坡道槽之间形成有容纳腔;多个滚球分别设置在各容纳腔中,滚球分别抵接在驱动侧坡道槽的两侧内壁上和/或滚球分别抵接在被驱动侧坡道槽的两侧内壁上,滚球能够在驱动侧转子与被驱动侧转子的相对旋转驱动下沿被驱动侧坡道槽移动,进而驱动驱动侧转子与被驱动侧转子沿轴向相对移动。本发明通过使滚球与坡道槽的两侧内壁形成两点接触,从而可以减少赫兹接触应力,提高了滚球的使用寿命。
