Abstract

PROBLEM TO BE SOLVED: To sufficiently lubricate a bearing on the end of a counter shaft by arranging an oil delivery hole which opens toward the bearing on the oil pump side end of the counter shaft and supplies a part of delivery oil to the bearing, in a delivery side passage of an oil pump. SOLUTION: A counter shaft 1 is rotatably journalled to a gear case 2 through a bearing 4. An oil pump 3 driven by a counter shaft 1 is installed in a gear case 2 in front of the counter shaft 1. The oil pump 3 sucks oil in a suction passage 5 through an oil sucking pipe in the gear case 2, and supplies the oil to respective oil feeding parts by a delivery passage 6. Here, an oil delivery hole 7 to supply a part of delivery oil to the bearing 4 is arranged in a delivery side passage of the oil pump 3. The oil delivery hole 7 is opened in a wall surface of an oil storage part 3a on the delivery side of the oil pump. Lubricating ability of the bearing is secured by this constitution, and a rise in an oil temperature is restrained, and an oil cooler can be reduced in the size or abolished.

ている問題があった。When the transmission is mounted on the vehicle, the front side where the oil pump 3 is installed is inclined upward as shown in FIG. Therefore, the oil is horizontal in the inclined gear case 1 and the oil temperature can be lowered by lowering the oil level OL.
The bearing 4 at the end on the side of the oil pump 3 is not immersed in oil, and poor lubrication occurs. In order to solve this problem, the oil level OL is increased so that the droplets sufficiently reach each oil supply unit. However, since the oil temperature rises, a large oil cooler is provided to lower the oil temperature. Therefore, there is a problem that not only the installation space for the oil cooler is required but also the cost is high.
