Abstract
A vehicle transfer case has a first input drive means, a first output drive means and a second output drive means. A first epicyclic gear set is provided in the transfer case. The first epicyclic gear set includes a first sun gear, a plurality of first planetary gears, a first planet carrier and a first ring gear. A first clutch means is configured to control the first epicyclic gear set. The first output drive means is drivingly coupled to the first input drive means; and the first clutch means selectively drivingly couples the second output drive means to the first input drive means.
Claims18
A transfer case for a vehicle driveline, the transfer case comprising:
- a first input drive;
- a first output drive;
- a second output drive;
- a first epicyclic gear set comprising a first sun gear, a plurality of first planetary gears, a first planet carrier, and a first ring gear,
- wherein the first output drive is continuously drivingly coupled to the first input drive;
- and
- a first clutch configured to control the first epicyclic gear set to selectively drivingly couple and de-couple the second output drive and the first input drive thereby to enable the transfer case to selectively disconnect a portion of the vehicle driveline that is coupled to the second output drive.
