A motor vehicle torque transmission apparatus incorporating a multi-stage torque converter, a main reduction gear and a stepless speed-change transmission. The multi-stage torque converter comprises separate stators. The main reduction gear is connectable to an output section of the multi-stage torque converter. Connected to one of the stators and to the main reduction gear is a stepless speed-change transmission therebetween, such that output torque of the stator is added to output torque of the main reduction gear.

Vehicle transmission incorporating multi-stage torque converter

A securing structure and method of a blade for torque converter for use mainly in industrial construction vehicles to provide its rigid and easy-to-manufacture construction. The structure includes plural circular blades which are secured to a concave surface of a shell with some space in the circumferential direction, a core ring which extends along the circumferential direction of the shell and is secured to concave peripheries of the blades. A tab fitting in slot of the shell is formed integrally on the convex periphery of the blade. A tab fitting in a slot of the core ring is formed integrally on the concave periphery of the blade. Ribs extending in the circumferential direction of the shell are only formed on both ends of the convex periphery and concave periphery of the blade. The convex periphery and the concave periphery are brazed to the shell and the core ring respectively.
