Title:
STEPLESS HYDRAULIC TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JPS56143862
Kind Code:
A
Abstract:
PURPOSE:To prevent a seize and damage of a sliding part and a piston etc. by a method wherein a clutch device is arranged in a transmitting line and a rotation of the input shaft is terminated during a low speed rotation of the engine. CONSTITUTION:Clutch device 67 for shutting off a motive power force during a low speed rotation of the input shaft 7 is installed in a transmission line for use in transmitting a motive power fouce to the input shaft 7. Thereby, when a rotational speed of the engine (not shown) is decreased, the second clutch means 97 is moved in a rightward direction against a centrifugal force of the balls 113, 113,... under a pressing force of the spring 107, engaging claw 101 is disengaged from the engaging claw 91, and the rotation of the input shaft 7 is terminated. Thus, when the rotation of the input shaft 7 is decreased, the stepless hydraulic transmission device 1 is changed to a high speed position and a rotation of the device is kept terminated, so that no seize and damage of the sliding parts and the piston etc. due to a lack of feeding of hydraulic oil is made.
