Abstract

PROBLEM TO BE SOLVED: To reduce the number of part items as well as to restrain a rise in cost and an increase of assembling manhours from occurring by disusing a lubricating oil injection pipe of a trans-axle. SOLUTION: A pipe 7 connected to an oil path hole 6 is installed in a lubricating oil passage 8 installed in a trans-axle case 1, housing an oil pump, a V-belt type continuous variable transmission, an idler gear and a differential gear, thereby lubricating the idler gear of a second countershaft part O3 and a bearing part of the differential gear. In addition, lubricating oil is sprayed to both these differential and idler gears from a discharge port P installed in a side face part of the pipe 7, whereby direct lubrication can be done without installing another pipe.

However, the transaxle has a three-axis structure including a main shaft portion for disposing a transmission, an intermediate shaft portion for disposing a geared intermediate shaft, and an auxiliary shaft portion for disposing a differential transmission device. In the case of the shaft configuration, complete lubrication cannot be achieved by the method of supplying the scraping oil as lubricating oil to each lubrication part.

Therefore, in order to supply the fluid from the hydraulic pressure supply source as lubricating oil, a structure has been considered in which a pipe is connected to the hydraulic pressure supply source and forced lubrication is performed via the pipe.

For example, Toyota Motor Corporation, 1986, March 3
In the "Toyota A240L 241L 242L Automatic Transaxle Repair Manual" issued in May, the hydraulic oil supply source, the transmission, the intermediate shaft with gears, and the differential transmission are housed in a common case, and the hydraulic oil supply path for the torque converter There is described a configuration in which the tip of a pipe connected to is inserted into a lubricating oil passage provided in the case, and the bearing of the differential transmission is lubricated by the hydraulic oil of the torque converter.

However, for example, since the differential transmission is constructed so as to be surrounded by the gear case that houses all the gear elements, when the differential transmission is completely lubricated, it is necessary to use the scraping oil. Separately, the lubricating oil must be supplied directly.

In this case, since the intermediate shaft with gears, which easily bears a load during operation, is located higher than the lower part inside the case, it is necessary to directly supply a lubricating oil different from the scraping oil.

Further, also in the case of a transaxle comprising a V-belt type continuously variable transmission in which a drive pulley and a driven pulley are connected by a V-belt, a gear for connecting the driven pulley and the differential transmission device is also provided. Since the attached intermediate shaft is arranged at a higher position than the structure in which the stepped automatic transmission is connected, the same problem occurs.

Therefore, in such a lubrication circuit, in addition to the lubricating oil supply pipe for lubricating the intermediate shaft with gears and the bearing of the differential transmission, the intermediate shaft with gears and the differential transmission are directly lubricated. Since it is necessary to separately provide each of the lubricating oil injection pipes of 1 to perform lubrication of the lubrication part,
The increase in the number of parts causes an increase in cost and an increase in man-hours for assembly.
