The invention belongs to the technical field of automobile mechanical steering gears, and discloses an automobile mechanical steering gear capable of preventing abnormal sound, which comprises a steering shell, steering corrugated pipes are fixedly connected to the two ends of the steering shell, a steering straight pull rod is movably connected to the interior of the steering shell, and a steering gear is fixedly connected to the bottom end of the steering straight pull rod. And one side of the steering gear is engaged with a steering rack, and the exterior of the steering straight pull rod is rotationally connected with a first rotating ring. By arranging the top plate, the upper ejector rod, the threaded rod, the threaded ring, the steel wire rope and other structures, after the top plate is rotated, the first fixing block drives the second fixing block to move, the second fixing block pushes the upper ejector rod to move, the upper ejector rod drives the threaded rod to be inserted into the threaded ring, the threaded ring rotates, and the steel wire rope is wound through the threaded ring belt; the steel wire rope pulls the second rotating ring through the fixing ring, so that abnormal sound is not prone to being generated between the steering rack and the steering gear, and the experience feeling of a driver is improved.

    本发明属于汽车机械转向器技术领域,且公开了一种防止异响的汽车机械转向器,包括转向壳体,所述转向壳体的两端固定连接有转向波纹管,所述转向壳体的内部活动连接有转向直拉杆,所述转向直拉杆的底端固定连接有转向齿轮,所述转向齿轮的一侧啮合有转向齿条,所述转向直拉杆的外部转动连接有第一转环。本发明通过设置有顶板、上顶杆、螺纹杆、螺纹环、钢丝绳等结构,将顶板转动后,第一固定块带动第二固定块移动,第二固定块推动上顶杆移动,上顶杆带动螺纹杆插入螺纹环内部,螺纹环转动,通过螺纹环带将钢丝绳缠绕,钢丝绳通过固定环拉动第二转环,使得转向齿条与转向齿轮之间不易产生异响,提高驾驶员的体验感。
