Abstract
Official abstract text for this publication.
A cooling unit of a drive motor includes: a fixing member installed on an inner wall surface of a motor housing and configured to fix a stator core of the drive motor, wherein the fixing member has a ring shape, includes a flow path formed therein in order to allow a cooling medium to flow, and includes a cooling medium inlet and a cooling medium outlet formed to be connected to the flow path, the flow path includes a first path connecting the cooling medium inlet and the cooling medium outlet to each other at one side and a second path connecting the cooling medium inlet and the cooling medium outlet to each other at another side, and the first and second paths have different flow cross sections and are connected to each other.
First claim
Opening claim text (preview).
What is claimed is: 1. A cooling unit of a drive motor, comprising: a fixing member installed on an inner wall surface of a motor housing and configured to fix a stator core of the drive motor, wherein the fixing member has a ring shape, includes a flow path formed therein in order to allow a cooling medium to flow, and includes a cooling medium inlet and a cooling medium outlet formed to be connected to the flow path, the flow path includes a first path connecting the cooling medium inlet and the cooling medium outlet to each other at one side and a second path connecting the cooling medium inlet and the cooling medium outlet to each other at another side, and the first and second paths have different lengths, a plurality of through-holes connected to the flow path are formed along an outer circumferential direction of the fixing member in an outer circumferential surface of the fixing member, and cap plugs are installed in the through-holes, and the cap plugs are inserted into the through-holes at different depths so as to each correspond to the first and second paths, and insertion depths of the cap plugs are varied by actuators. 2. The cooling unit of a drive motor of claim 1 , wherein: the first and second paths have the same flow cross section and are connected to each other. 3. The cooling unit of a drive motor of claim 2 , wherein: the first path has a length longer than that of the second path. 4. The cooling unit of a drive motor of claim 3 , wherein: an insertion depth of the cap plugs corresponding to the second path is deeper than that of the cap plugs corresponding to the first path. 5. The cooling unit of a drive motor of claim 4 , wherein: the actuators include operation cylinders connected to the cap plugs corresponding to the second path.
