无链自行车及其传动系统
摘要：
本发明提供一种圆锥齿轮-传动杆传动方式的无链自行车及其传动系统。传动系统包括：中轴，其上安装有作为驱动齿轮的第一圆锥齿轮；后轴，其上安装有作为从动齿轮的第二圆锥齿轮；传动杆，其杆上的中轴侧端部安装有与第一圆锥齿轮啮合的第三圆锥齿轮，其后轴侧端部安装有与第二圆锥齿轮啮合的第四圆锥齿轮。第一圆锥齿轮、第二圆锥齿轮、第三圆锥齿轮、以及第四圆锥齿轮均为轴交角被设计成90度的圆锥齿轮；第三圆锥齿轮与第一圆锥齿轮以90度轴交角啮合传动，随第一圆锥齿轮的旋转而旋转；第二圆锥齿轮与第三圆锥齿轮以90度轴交角啮合传动，随第三圆锥齿轮的旋转而旋转。
摘要（英）：

The invention provides a chainless bicycle using a bevel gear-transmission rod transmission mode and a transmission system thereof. The transmission system comprises a middle shaft, a rear shaft and a transmission rod. The middle shaft is provided with a first bevel gear serving as the driving gear. The rear shaft is provided with a second bevel gear serving as the driven gear. The middle shaft side end part of the transmission rod is provided with a third bevel gear engaged with the first bevel gear and the rear shaft side end part thereof is provided with a fourth bevel gear engaged with the second bevel gear. The first bevel gear, the second bevel gear, the third bevel gear and the fourth bevel gear are all bevel gears with the shaft angles being 90 DEG. The third bevel gear is in engaged transmission at the shaft angle of 90 DEG with the first bevel gear and rotates along with the rotation of the first bevel gear. The second bevel gear is in engaged transmission at the shaft angle of 90 DEG with the third bevel gear and rotates along with the rotation of the third bevel gear.
