Title:
HYDRAULIC CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
Japanese Patent JP2004068974
Kind Code:
A
Abstract:
To solve a conventional problem that when a housing of a servo mechanism is formed separately from the housing of an HST main body for providing the servo mechanism to a two-pump two-motor type HST, or an actuator for operating swash plate angle of a variable capacity hydraulic motor is formed separately from the housing of the HST main body, the HST becomes large in size and high in cost.
A two-pump two-motor type hydraulic continuously variable transmission 1 respectively composed of a pair of hydraulic pumps 11, 21 and a pair of hydraulic motors 12, 22 is provided with the servo mechanism 61 for operating the hydraulic continuously variable transmission 1, and integrally formed with one housing 31.
