Title:
TRANSMISSION PROPERTIES CONTROLLER OF STEPLESS TRANSMISSION GEAR
Document Type and Number:
Japanese Patent JPS59222660
Kind Code:
A
Abstract:
PURPOSE:To enable transmission properties to be changed according to a running condition, by a method wherein, in a circular Pitot pressure chamber, Pitot pressure properties are variable through movement in the direction of radius of the nozzle end, serving as a measuring point, of a Pitot tube. CONSTITUTION:An annular case 70 is secured to the back of a cylinder 27a of a hydraulic servo device 27, and a circular Pitot pressure chamber 74, through which fluid leaks properly, is formed by a cylinder 27a, the case 70, a wall part 72 of the side case of a transmission gear, and a bearing 73 of a main shaft 17. At the inside and the outside of the Pitot pressure chamber 74, a Pitot tube 77 is installed such that the base part thereof is secured to a shaft 78, and a nozzle end 77a, being a measuring point, is rotatably between a radial direction and a horizontal direction. A Pitot pressure, which is proportioned to rotation of an engine converted into a pressure by the Pitot tube 77, is exerted on a pressure regulating valve and the Pitot tube 77 is turned, and this enables change of Pitot pressure properties.
