Zusammenfassung: | To solve a problem that, when mounting an electric oil pump to a vehicle, it is difficult to secure an installation place of the electric oil pump, and the oil pump should be accommodated in an oil pan sometime, however, on the other hand, in an electric oil pump which is incorporated with a driver, a high-heat resistance driver is required for use, thus causing a high cost.SOLUTION: A pump part 56 of an electric oil pump 50 and a motor part 54 are accommodated in a space which is formed of a case 41 of a transmission 20 and an oil pan 70, and a drive part 52 being a drive circuit is installed so as to be exposed from the space. By this constitution, it becomes unnecessary to use a high-heat resistance member to a driver part, and also it becomes easy to secure an installation place of the electric oil pump 50 by accommodating the pump part 56 and the motor part 54 in the space.SELECTED DRAWING: Figure 2
【課題】電動オイルポンプの車両への搭載において、前記電動オイルポンプの設置場所を確保することが難しく、前記電動オイルポンプをオイルパン内に収納する場合があった。ドライバを内蔵した電動オイルポンプにおいては、高耐熱のドライバの使用が必要となり、高コストとなっていた。【解決手段】電動オイルポンプ50のポンプ56部とモータ部54とを変速機20のケース41とオイルパン70からなる空間内に収納し、駆動回路であるドライブ部52を前記空間から露出するように設置する。これによって、ドライバ部に高耐熱の部材を用いる必要が無くなるとともに、ポンプ56部とモータ部54とを前記空間に収納することによって、電動オイルポンプ50の設置場所の確保が容易となった。【選択図】図2 |
