Problems solved by technology

Therefore, the hydraulic oil flow direction is changed by 90 degrees from the supply oil passage to the torque converter side, and the flow direction is changed by 90 degrees from the torque converter to the discharge oil passage, and the flow resistance of the hydraulic oil is relatively large.
In addition, if the arrangement of the auxiliary machine with respect to the torque converter is changed, the passage of the hydraulic oil becomes complicated, leading to an increase in the size of the transmission

Abstract

A supply oil passage for supplying operating oil to a torque converter supporting a worm wheel, a pump impeller, and a stator impeller on a rotating shaft and a discharge oil passage for leading out operating oil discharged from the torque converter extend along the axial direction of the rotating shaft at the same time. The transmission devices arranged on the rotating shaft at intervals along the axial direction smooth the flow of working oil in the front and rear of the torque converter, suppress flow resistance, and contribute to improving the transmission efficiency of the torque converter and increasing the freedom of arrangement. Spend. The torque converter (46) is arranged on the rotating shaft (15), the worm wheel impeller (57) is arranged on the supply oil passage (53) side, and the pump impeller (58) is arranged on the discharge oil passage (54) side; 53) The supply side inclined oil passage (101) where the operating oil is directed to the pump impeller (58) and the discharge side inclined oil passage (102) where the operating oil discharged from the worm wheel (57) is directed to the discharge oil passage (54) has a relative The axis of the rotation shaft is arranged axially inclined on the rotation shaft.

Description

technical field [0001] The present invention relates to a supply oil passage for supplying hydraulic oil to a torque converter supporting a worm wheel, a pump impeller, and a stator impeller on a rotating shaft, and a discharge oil passage for leading out hydraulic oil discharged from the torque converter extending along the axial direction of the rotating shaft. , and the improvement of the transmission device arranged on the rotating shaft spaced apart from each other. Background technique [0002] There is known a transmission device for a small vehicle, such as described in Patent Document 1, in which a torque converter is provided between the crankshaft of the engine and the transmission, and a worm wheel, a pump impeller, and a stator impeller are arranged on the crankshaft. On the crankshaft, a supply oil passage for supplying hydraulic oil to the torque converter and a discharge oil passage for leading hydraulic oil discharged from the torque converter are coaxially ...
