车辆用动力传递装置
摘要：
本发明提供一种车辆用动力传递装置，将变速箱体的重量增加抑制为最小限度并且抑制振动而降低噪音。变速箱体(11)由与驱动源(E)连结的支承框架(51)以及覆盖支承框架和多个传递单元(14)的密封盖(52)构成，支承框架(51)由一对侧部框架(54、55)以及连结框架(56、57)构成，所述一对侧部框架支承输入轴(12)和输出轴(13)的两端部，连结框架在输入轴(12)与输出轴(13)之间在不与连接杆(33)的移动轨迹干渉的位置将一对侧部框架连结，因此，由支承框架分担支承输入轴和输出轴的支承功能，由密封盖分担防止来自变速箱体的噪声或漏油的密封功能，由此，能够将变速箱体的重量抑制为最小限度并且实现无级变速器(T)的防振以及防音。
摘要（英）：

The invention provides a power transmission device for a vehicle and can reduce noise by suppressing vibration while minimizing increase of a weight of a mission case of a power transmission device for a vehicle.As a mission case (11) is composed of a supporting frame (51) connected to a driving source (E), and a seal cover (52) covering the supporting frame (51) and a plurality of transmission units (14), and the supporting frame (51) is composed of a pair of side frames (54, 55) supporting both end portions of an input shaft (12) and an output shaft (13), and connection frames (56, 57) connecting the pair of side frames (54, 55) at a position free from interference with a moving locus of a connection rod (33) between the input shaft (12) and the output shaft (13), the supporting frame (51) bears a supporting function for supporting the input shaft (12) and the output shaft (13), and the seal cover (52) bears a sealing function for preventing noise from the mission case (11) and leakage of an oil, thus vibration control and noise control of a continuously variable transmission (T) can be achieved while minimizing a weight of the mission case (11).
