Title:
HYDROSTATIC VARIABLE TRANSMISSION
Document Type and Number:
Japanese Patent JP3695576
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce oil leakage and increase efficiency at hydrostatic variable transmission in combination with a swash plate hydraulic pump and a swash hydraulic motor.
SOLUTION: The hydrostatic variable transmission integrally connected is characterized by not only that a hydraulic closed circuit is established between the swash plate hydraulic pump and the swash plate hydraulic motor, but that an output shaft 27 is press-fitted into a cylinder block 8 in which a pump cylinder hole 8 and motor cylinder hole 18, in parallel with the output shaft 27 are drilled but also that diameters of depths 8 (a) and 18 (a) of the pump cylinder hole 8 and the motor cylinder hole are made greater than diameters of the inlets 8b and 18b and also that press-fitted parts are not established at contact parts 30 with the outlet shaft 27 in the inlet part 8b and 18b.
