摘要： A pulley mechanism of a vehicular belt-type continuously variable transmission that makes it possible to enhance the joint strength between a rotary shaft and a stationary sheave without increasing the axial length of the belt-type continuously variable transmission is provided. Since a first stationary portion and a second stationary portion are provided on both sides of a step portion respectively, a stationary sheave is fixed by this first stationary portion and this second stationary portion, and the joint strength between the stationary sheave and an output shaft increases. Besides, a belt reaction force during power transmission can be received by the first stationary portion and the second stationary portion. Therefore, the amount of inclination of the stationary sheave during power transmission is also held small, and a fall in the torque capacity and transmission efficiency of the belt-type continuously variable transmission and a deterioration in the NV characteristics of the belt-type continuously variable transmission can be suppressed.
摘要翻译： 提供了一种车用带式无级变速器的滑轮机构，其能够在不增加带式无级变速器的轴向长度的情况下提高旋转轴和固定滑轮之间的接合强度。 由于第一静止部分和第二静止部分分别设置在阶梯部分的两侧，所以固定滑轮由该第一固定部分和该第二固定部分固定，并且固定滑轮和输出轴之间的接合强度增加 。 此外，动力传递期间的带反作用力可以由第一固定部分和第二固定部分接收。 因此，传动期间固定滑轮的倾斜度也保持较小，带式无级变速器的转矩容量和传动效率下降，带式无级变速器的NV特性的劣化 可以抑制传输。
