Heat exchanging device of lubrication oil
First Claim
1. A heat exchanging device of lubrication oil for exchanging heat of the lubrication oil which circulates in a transmission for a vehicle, comprising:
- a first lubrication oil circulating circuit through which a first lubrication oil circulates to be supplied to a friction engaging device of the transmission;
a second lubrication oil circulating circuit through which a second lubrication oil circulates to be supplied to mechanisms other than the friction engaging device of the transmission;
a cooling water circulating circuit through which a cooling water circulates to cool a driving source of the vehicle;
a first heat exchanger for exchanging heat between the first lubrication oil and the second lubrication oil; and
a second heat exchanger for exchanging heat between the first lubrication oil and the cooling water.

Abstract
A cooling device for cooling lubrication oil which circulates in a vehicle transmission is provided with a first oil circulating circuit through which a clutch oil for lubricating a first and second clutch of the transmission circulates, a second oil circulating circuit through which a gear oil circulates to lubricate mechanisms other than the first and the second clutches, and a cooling water circulating circuit through which a cooling water circulates to cool an engine and a motor. Also provided is a first heat exchanger exchanging heat between the first lubrication oil and the second lubrication oil, and a second heat exchanger exchanging heat between the first lubrication oil and the cooling water.
