Title:
PLANETARY ROLLER TRANSMISSION AND VEHICLE HAVING THE SAME
Document Type and Number:
WIPO Patent Application WO/2007/029564
Kind Code:
A1
Abstract:
A planetary roller transmission, comprising a plurality of planetary rollers
(23) having an input shaft (11) and an output shaft (13) installed rotatably on
a same axis and allowed to roll on the outer periphery of a sun roller (19) installed
on the input shaft (11), an output ring (35) formed integrally with the output
shaft (13) and allowing the planetary rollers (23) to internally roll thereon,
and a speed change ring (37) installed movably only in the radial direction of
the input shaft (11) and the output shaft (13) and allowing the planetary rollers
(23) to internally roll thereon. The position of the sun roller (19) where the
sun roller presses the planetary rollers (23) in the outer direction is located
between a position where the output ring (35) touches the planetary rollers (23)
and a position where the speed change ring (37) touches the planetary rollers
(23). The planetary roller transmission further comprises an axially pressing
member (55) axially movable by a centrifugal force generated when the input shaft
(11) is rotated.
