Title:
HYDRAULIC TYPE CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
Japanese Patent JP2011043202
Kind Code:
A
Abstract:

To solve the problem of a hydraulic type continuously variable transmission, including a hydraulic pump part and a hydraulic motor part provided through a cylinder block interlocked with an input shaft, with both parts connected by a closed circuit, in which the flow direction in the closed circuit is variable to vary the rotation direction and the rotation number of the hydraulic motor part to the cylinder block, wherein the inclination angle of a swash plate in the hydraulic motor part is not variable, causing a narrow changeable speed range width.

In the hydraulic continuously variable transmission 1, both a first swash plate 52 of the hydraulic pump part 41 and a second swash plate 53 of the hydraulic motor part 40 are composed in a variable type in which the inclination angle d is variable.
