Continuously Variable Transmission

摘要

A cage (1589) for facilitating the support and guidance of a traction roller assembly in a continuously variable transmission, the cage (1589) comprising: a first cage disc (1586) comprising a first plurality of angularly spaced apart 5 radial grooves (2202), the first plurality of radial grooves (2202) configured to receive a roller axle of the traction roller assembly, the first plurality of radial grooves (2202) extending perpendicularly from a longitudinal axis; and a second cage disc (1587) comprising a second plurality of angularly spaced apart radial grooves (2202), the second plurality of radial grooves (2202) configured 10 to receive the roller axle, the second plurality of radial grooves (2202) extending perpendicularly from the longitudinal axis, wherein the first (1586) and second (1587) cage discs are positioned such that the first plurality of radial grooves is angularly offset relative to the second plurality of radial grooves, wherein the first and second cage discs (1586; 1587) are adapted to be mounted coaxially with a longitudinal axis 15 of the continuously variable transmission, and wherein the first cage disc (1586) and the second cage disc (1587) each comprise a bore adapted to engage a main shaft of the continuously variable transmission.
