Abstract

PURPOSE: To prevent the burning of pump by installing a transmission mechanism which interlocks a transmission operating lever and increases the speed of either pump or engine, between a pump and an engine and by interlocking a gearbox and operating the pump at high speed.
CONSTITUTION: The revolution of an engine is applied through an input shaft 17 to a hydraulic infinitely variable gearbox 10 which consists of a variable capacity axial plunger pump 15 and a constant capacity axial plunger motor 16. After operating the gearbox properly based on the operation of a throttle lever 14 and a gearshift lever 12 for a tilted plate 19 of the pump 15, the revolution of the engine is transmitted to crawlers from an output shaft 22. When the engine operates at low speed with the throttle lever 14 at a solid line, the gearshift lever 12 is rotated from a neutral position indicated with a solid line. The throttle lever 14 is then interlocked and moved to a position indicated with a chain line through an operation cam 38, a cam follower 42 and an L lever 40, increasing the speed of the engine simultaneously.
