摘要： A transmission has a drive train which is coupled with the engine, e.g. an automotive vehicle and a reversing gear connected to the output shaft. A slidable gear shifted on a fixed shaft, continuously meshes with a gear of the drive train and can be brought into mesh with the reversing gear for reverse drive. According to the invention the shiftable gear is connected with a synchronizing ring which has a frustoconical surface engaging the frustoconical surface of a synchronizing disk which is keyed to the fixed shaft when the slidable gear is shifted toward the reversing gear to stand still. The synchronizing disk or member on the shaft can be entrained with the sliding gear upon overcoming the force of a detent formed by a bore on the fixed shaft which is biased outwardly by a wedge member and an axial spring in the fixed shaft.
摘要翻译：变速器具有与发动机联接的传动系，例如。连接到输出轴的机动车辆和倒车齿轮。可滑动的齿轮在固定轴上移动，与传动系的齿轮连续啮合，并可与反向齿轮啮合以进行反向驱动。根据本发明，可移动齿轮连接有同步环，该同步环具有接合同步盘的截头圆锥形表面的截头圆锥形表面，当同步盘可滑动齿轮朝向反向齿轮移动以静止时，该同步圆盘被固定在固定轴上。轴上的同步盘或构件可以克服由固定轴上的孔形成的制动器的力而与滑动齿轮夹带，该止动件由固定轴上的楔形构件和轴向弹簧向外偏压。
