Title:
HYDROSTATIC CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
Japanese Patent JP3205597
Kind Code:
B2
Abstract:
PURPOSE: To facilitate the dimensional control and enhance the assembling properties of a hydrostatic continuously variable transmission in which a cylinder block is formed from ferrous metal with at least one annular oil passage formed near the inner periphery of the cylinder.
CONSTITUTION: At least two annular raised parts 82-84 are provided on the outer periphery of a cylinder 51 made of a nonferrous metal of a coefficient of thermal expansion greater than those of ferrous metals, with annular grooves 85, 86 formed between the raised parts, and the annular raised part 84 has its outside diameter set to a value at which it can be pressed into the center hole 49 of a cylinder block B, and each of the remaining annular raised parts 82, 83 has its outside diameter set to a value at which when assembled it forms a gap with respect to the inner surface of the center hole 49, while when used it makes intimate contact with the inner surface of the center hole 49. At least one annular oil passage 11, 87 is formed by the annular grooves 85,86 between the cylinder 51, in which the annular raised part 84 is pressed and fixed by insertion into the center hole 49, and the cylinder block B.
