Problems solved by technology

In particular, in the case of a hybrid drive device for FR, as the size of the vehicle mounted on it increases, a larger-capacity motor is used for the drive motor, and a large amount of heat is generated accordingly, so a large amount of oil is used by the drive. It is used with a motor, and the oil pan is arranged at the lower part of the drive motor box, so the oil mixed with a lot of resin flakes is easy to flow directly back into the oil pan
[0008] Due to the specific gravity, metal shavings will sink to the bottom of the oil pan, and the situation that the oil drain hole of the valve body located on the upper part of the oil pan invades into the oil drain hole is relatively small, but the resin flakes float in the oil, and finally come out of the drain hole. High possibility of oil hole intrusion into valve hole

Abstract

Drain holes are arranged in positions offset from valve holes of a valve body. The drain holes have a long chimney-shaped space such that even if insulation material, that has peeled off of an electric motor, is suspended in oil, it is less likely to enter drain chambers through the drain holes.

Description

technical field [0001] The present invention relates to a hydraulic circuit device suitable for use in a power transmission system mounted on an automobile, especially a valve body of a hybrid drive device, and specifically relates to oil discharge of the hydraulic circuit device. Background technique [0002] Generally, in the power transmission system of an automatic transmission or a hybrid drive installed in an automobile, there is a hydraulic circuit device that supplies engine oil that becomes lubricating oil or hydraulic oil. The hydraulic circuit device consists of a valve body and Various valves are arranged in the valve body, and the valve body is arranged in an oil pan provided at the lower part of the casing of the automatic transmission or the hybrid drive device. [0003] The above-mentioned valve body is equipped with an oil filter below it, and the oil in the oil pan is sucked through the oil filter, and the pressure is regulated by using the switching valve ...
