Arrangements for suppressing or influencing the differential action, e.g. locking devices

Introduced: January 1995

Full Title

Full titles differ between systems:

IPC:

Differential gearings > Arrangements for suppressing or influencing the differential action, e.g. locking devices

CPC:

Differential gearings (cooling or lubricating of differential gearing F16H57/04) > Arrangements for suppressing or influencing the differential action, e.g. locking devices

Of 10 combined children, 7 exist in both systems.

3 codes are CPC-only extensions.

Note: 3 CPC extensions are marked as secondary classification only.

IPC defines codes here since 1995.
