TRANSMISSION OF WORKING VEHICLE

摘要

PROBLEM TO BE SOLVED: To dispense with a dedicated oil tank for working oil by positioning a variator shaft for mounting a toroidal transmission mechanism in an upper position of a transmission case to enable appropriate lubrication.

SOLUTION: This transmission is structured such that the variator shaft 10 for mounting the toroidal transmission mechanism 4 is arranged on an axial extension of an engine output axis and in the uppermost position in the transmission case 1; input discs 4b to the toroidal transmission mechanism 4 are mounted to the variator shaft 10; output discs 4a are fixed to the variator shaft 10 by interposing the input discs 4b on the front and back sides; and torque is transmitted to the input discs 4b from a running drive input shaft 11 located below the variator shaft 10 and arranged in parallel with the shaft 10 through gears 21, 22 and 23.
