Title:
HYDROSTATIC TYPE CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
Japanese Patent JP2020002917
Kind Code:
A
Abstract:
To provide a hydrostatic type continuously variable transmission that can be put into a neutral state while restraining increases in size and cost.SOLUTION: A hydraulic motor 12 is provided with a separation mechanism 51 for separating a cylinder block 32 from a valve plate 34. When the cylinder block 32 is separated from the valve plate 34, hydraulic oil is discharged into a gap 58 generated between the cylinder block 32 and the valve plate 34 through an opening 42 from each cylinder 41 of the cylinder block 32. As a result, a motor rotating shaft 31 and the cylinder block 32 of the hydraulic motor 12 become freely rotatable, and the hydraulic motor 12 enters a neutral state.SELECTED DRAWING: Figure 3
