摘要： If a sleeve of a double cone-type synchronizer is not smoothly engaged with a dog gear because of getting caught by the dog gear, the dog gear, as pressed by the sleeve, may lean with a spline-connecting part of the dog gear to a transmission gear as a fulcrum, so that an inner ring of a blocking ring may be damaged by being squeezed between the dog gear and a hub. However, the transmission gear includes: a tooth surface portion having tooth surfaces formed on one axial end side of the transmission gear; and a contact portion formed on the opposite axial end side, and abutting against the dog gear. The contact portion extends radially outward of a through-hole of the dog gear, thereby preventing the dog gear, as pressed by the sleeve, from leaning toward the transmission gear so as to prevent damage of the inner ring.
摘要翻译： 如果双锥形同步器的套筒由于被齿轮卡住而不能与狗齿轮平滑地啮合，则通过套筒按压的狗齿轮可以与狗齿轮的花键连接部分一起倾斜 传动齿轮作为支点，使得阻塞环的内环可能通过在齿轮和轮毂之间被挤压而损坏。 然而，传动齿轮包括：齿面部，其具有形成在变速齿轮的一个轴向端侧的齿面; 以及形成在所述相对的轴向端侧上并抵靠所述齿轮的接触部。 接触部分径向地延伸到齿轮的通孔的外侧，从而防止被套筒按压的齿轮齿轮朝向传动齿轮倾斜，以防止内圈损坏。
