Title:
SPEED CHANGING LEVER SUPPORTING STRUCTURE IN MOVING AGRICULTURAL MACHINE
Document Type and Number:
Japanese Patent JP3666957
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a mechanism which enables a hydraulic continuously variable transmission to perform an accurate speed changing operation according to the swivel operation of a main speed changing lever.
SOLUTION: The swivel fulcrum shaft 28 of a main speed changing lever 14 freely swung for performing a speed changing operation for a hydraulic continuously variable transmission 17 for speed-changing the rotation driving force of an engine in a continuously variable manner and the work shaft 34 of the hydraulic continuously variable transmission 17 are connected to each other via a connecting tool 33. The fulcrum shaft 28 is connected to and supported in the hydraulic continuously variable transmission 17 by two or more stators 26 and 43 such that the application line of a force exerted on the fulcrum shaft 28 side forms a triangle with the fulcrum shaft 28 side as a vertex when seen from the front side. The stator 43 is directed attached to the fulcrum shaft 28 by a plurality of nuts 39 and 41 engaged with the fulcrum shaft 28 for adjusting the operation load of the main speed changing lever 14 for preventing fluctuations in the swinging angle of the main speed changing lever 14 by a reactive force from the hydraulic continuously variable transmission 17 side.
