Title:
ハイドロスタティックトランスミッションシステム
Document Type and Number:
Japanese Patent JP3623101
Kind Code:
B2
Abstract:
An object of the present invention is to provide a hydrostatic transmission system integrally constructed without being large-sized while incorporating a variable displacement motor therein. In order to accomplish the object, a casing 11 has a variable displacement pump 1 and a variable displacement motor 3 incorporated therein in a manner to be juxtaposed to each other. The pump 1 is constituted by a cam plate type axial plunger pump which is constructed so as to render a tilting angle of a cam plate 18 variable and render a discharge rate of hydraulic fluid zero when the tilting angle is within a range set near 0 degree. The motor 3 is constituted by a cam plate type axial plunger motor including a cam plate 33 of which a tilting angle is variable. A cover 48 is provided with a pair of passages 2a and 2b, relief valves 9a and 9b, check valves 10a and 10b, and a change-over valve 5.
