ELECTRIC DRIVE UNIT HAVING A COOLING SLEEVE

The invention relates to an electric drive unit (2, 82, 86) having an electric machine (4, 70) arranged in a motor housing (18, 22, 58, 64, 76, 92, 94) comprising a rotor (14) and a stator (30, 72). Said electric drive unit has a gear mechanism (8) that is arranged in a gear housing (54, 66) and is driven by the electric machine (4. 70). A cooling sleeve (36, 60, 74, 96) is provided, which, in theradially outward direction, forms a cavity (52, 98) for a coolant by means of a spiral-shaped circumferential web (38, 100) between itself and the surrounding motor housing (18, 22, 58, 64, 76). Thecooling sleeve (36, 60, 74, 96) further has a holding web (40, 62, 88, 102), which is designed to be clamped in between two motor housing parts (18, 22, 58, 64, 76, 92, 94). 本发明涉及一种电驱动单元(2、82、86)，其具有布置在马达壳体(18、22、58、64、76、92、94)中的、包括转子(14)和定子(30、72)的电机(4、70)，该电驱动单元具有布置在传动机构壳体(54、66)中的并且由电机(4、70)驱动的传动机构(8)。设置有冷却套(33、60、74、96)，该冷却套径向向外通过螺旋形环绕的接片(38、100)在其本身与进行包围的马达壳体(18、22、58、64、76)之间形成了用于冷却剂的空腔(52、98)。此外，冷却套(33、60、74、96)具有保
