The invention belongs to the technical field of semitrailer rear wheel steering control, and particularly relates to a semitrailer rear wheel steering control device which comprises a semitrailer frame and a transmission rod. The device further comprises a guide cavity and a controller. The section of the semitrailer frame is rectangular, and the center of one end face of the semitrailer frame isrotationally connected with a first gear; the first gear is engaged with a second gear; the second gear is rotationally connected with one end face of the semitrailer frame; a motor is mounted in thesemitrailer frame; an output shaft of the motor is connected with the middle of the second gear; and the end face of the first gear is fixedly connected with a fixing rod. The first gear drives the transmission rod to slide along the inner wall of the guide cavity, and the guide cavity drives a first disc to rotate in a circular groove, so that rear wheels rotate under the action of the transmission rod, and compared with the prior art, the device has improved transmission efficiency and transmission precision; and meanwhile, the situation that the rear wheels rotate in a delayed mode is avoided, and the passing rate of the semitrailer is increased.
本发明属于半挂车后轮转向控制技术领域,具体涉及一种半挂车后轮转向控制装置,包括车架和传动杆;还包括引导腔和控制器;所述车架的截面形状为矩形,车架的一端面中心处转动连接着一号齿轮;所述一号齿轮啮合着二号齿轮;所述二号齿轮转动连接在车架的一端面;所述车架的内部安装有电机;所述电机的输出轴连接着二号齿轮的中部;所述一号齿轮的端面固连有固定杆;本发明通过一号齿轮带动传动杆沿着引导腔的内壁滑动与引导腔带动一号圆盘在圆槽内转动相配合,使得后轮在传动杆的作用下发生转动,使得本发明相比较现有技术的传动效率和传动精度得到提高,同时还不会出现后轮转动延迟的情况,进而提高了半挂车的通过率。
