The invention discloses a racing car steering mechanism adapting to manned and unmanned dual modes. The racing car steering mechanism comprises a steering wheel, a first rotating shaft, a second rotating shaft, a sun gear, planet gears, a worm gear, a worm, a motor, a planet carrier, a third rotating shaft, a fourth rotating shaft, an output gear and a steering tie rod. The steering wheel is connected with the second rotating shaft through the first rotating shaft; the second rotating shaft is connected with the sun gear; gear teeth are arranged on the inner wall of the worm gear, the planetary gears are meshed with the gear teeth, and the sun gear is meshed with the planetary gears simultaneously; the planet carrier is connected with the planet gears and the third rotating shaft, the third rotating shaft is connected with the fourth rotating shaft through a steering universal joint, the fourth rotating shaft is connected with the output gear, and the output gear is meshed with a toothed bar on the steering tie rod; the motor is fixedly connected with the worm which is in transmission connection with the worm gear; and the spiral angle of the worm is smaller than the equivalent friction angle between the gears. A power separation device does not need to be adopted, the steering mechanism is simplified, the occupied space is reduced, and lightweight design of the racing car is facilitated.

    本发明公开了一种适应有人和无人驾驶双模式的赛车转向机构,包括方向盘、第一转轴、第二转轴、太阳轮、行星齿轮、蜗轮、蜗杆、电机、行星架、第三转轴、第四转轴、输出齿轮和转向横拉杆;方向盘通过第一转轴与第二转轴连接,第二转轴与太阳轮连接;蜗轮内壁设有轮齿,行星齿轮与轮齿啮合,太阳轮与多个行星齿轮同时啮合;行星架与行星齿轮连接,行星架与第三转轴连接,第三转轴通过转向万向节与第四转轴连接,第四转轴与输出齿轮连接,输出齿轮与转向横拉杆上的齿条啮合;电机与蜗杆固定连接,蜗杆与蜗轮传动连接;蜗杆的螺旋角小于齿轮间的当量摩擦角。本发明无需采用动力分离装置,简化了转向机构,减小了占用空间,有利于赛车的轻量化设计。
