Assembly structure of hybrid transmission

1. An assembly structure of a hybrid transmission comprising:

an engine clutch retainer having an assembly hole;

a coupling member configured to be coupled to the engine clutch retainer through the assembly hole; and

a sealing cover configured to seal the assembly hole,

wherein the engine clutch retainer has an accommodation hole to which the sealing cover is correspondingly coupled, and the accommodation hole is defined on an engine clutch piston side to communicate with the assembly hole defined on a side of an assembly bearing and is larger than the assembly hole.

2. The assembly structure of a hybrid transmission according to claim 1 , wherein the engine clutch retainer is disposed between the assembly bearing and an engine clutch piston.

3. The assembly structure of a hybrid transmission according to claim 2 , wherein the coupling member is configured to be coupled through the assembly hole to fix the assembly bearing.

4. The assembly structure of a hybrid transmission according to claim 2 , wherein the sealing cover comprises:

a through-hole defined at a center of the sealing cover; and

a recessed ring disposed on a surface facing the engine clutch piston and recessed along a circumference of the through-hole.

5. The assembly structure of a hybrid transmission according to claim 4 , wherein the recessed ring comprises:

a recessed surface having a tool engaging portion;

an inner ring portion disposed on an inner side of the recessed surface and has an inclined surface; and

an outer ring portion disposed on an outer side of the recessed surface, the outer ring portion having an inclined surface and being larger than the inner ring portion.

6. The assembly structure of a hybrid transmission according to claim 5 , wherein the tool engaging portion has a rib.

7. The assembly structure of a hybrid transmission according to claim 2 , wherein the assembly bearing has a rim portion, and the rim portion is disposed on an outer circumference of the assembly bearing and has a coupling hole to which the coupling member is correspondingly coupled.

8. The assembly structure of a hybrid transmission according to claim 2 , wherein the assembly bearing is configured to rotatably support the engine clutch retainer in a state of being fixed to a support by the coupling member.

9. The assembly structure of a hybrid transmission according to claim 1 , wherein a watertight member is disposed on an outer circumference of the sealing cover, and the watertight member is configured to seal a portion in contact with the accommodation hole.

10. The assembly structure of a hybrid transmission according to claim 1 , wherein the engine clutch retainer is configured integrally with a motor rotor.

11. The assembly structure of a hybrid transmission according to claim 1 , wherein the coupling member has a bolt.

12. The assembly structure of a hybrid transmission according to claim 1 , wherein the engine clutch retainer is configured integrally with a magnet.

13. An assembly structure of a hybrid transmission comprising:

an engine clutch retainer having an assembly hole;

a coupling member configured to be coupled to the engine clutch retainer through the assembly hole; and

a sealing cover configured to seal the assembly hole,

wherein the sealing cover comprises:

a through-hole defined at a center of the sealing cover; and

a recessed ring disposed on a surface facing an engine clutch piston and recessed along a circumference of the through-hole.

14. An assembly structure of a hybrid transmission comprising:

an engine clutch retainer having an assembly hole;

a coupling member configured to be coupled to the engine clutch retainer through the assembly hole; and

a sealing cover configured to seal the assembly hole,

wherein the engine clutch retainer is configured integrally with a motor rotor or a magnet.
