Abstract
A transfer case for a vehicle. The transfer case may include a rotation direction portion and an output mode portion configured to be driven by the rotation direction portion. The rotation direction portion may provide torque in different directions to the output mode portion. The output mode portion may selectively provide output torque to one or more outputs.
Claims20
A transfer case comprising:
- a rotation direction portion that includes:
- an input shaft configured to receive an input torque;
- first and second gear sets selectively coupled to the input shaft;
- and
- a gear set selector unit configured to move between a forward position in which torque is transmitted through the first gear set and a reverse position in which torque is transmitted through the second gear set;
- and
- an output mode portion configured to be driven by the rotation direction portion, the output mode portion including:
- first and second outputs configured to provide an output torque;
- and
- a mode selector unit disposed proximate the second output and configured to move between a first position and a second position;
- wherein torque is transferred to the first and second outputs when the mode selector unit is in the second position.

A transfer case for a vehicle, comprising:
- a rotation direction portion that includes:
- an input shaft configured to receive an input torque from a transmission;
- first and second gear sets selectively driven by the input shaft;
- and
- a gear set selector unit configured to move between a forward position in which torque is transmitted through the first gear set and a reverse position in which torque is transmitted through the second gear set;
- and
- an output mode portion configured to be driven by the rotation direction portion, the output mode portion including:
- first and second outputs configured to provide torque to first and second traction wheel sets, respectively;
- and
- a mode selector unit disposed proximate the second output and configured to move between a first position and a second position;
- wherein torque is transferred from the rotation direction portion to the output mode portion in a first rotational direction when the gear set selector unit is in the forward position and in a second rotational direction when the gear set selector unit is in the reverse position;
- and
- wherein torque is transferred to the first output but not the second output when the mode selector unit is in the first position and the first and second outputs when the mode selector unit is in the second position.
10 more elements
A transfer case for a vehicle, comprising:
- a first shaft for receiving an input torque, the first shaft configured to rotate about a first axis of rotation;
- a second shaft configured to rotate about a second axis of rotation;
- first and second gear sets that selectively couple the first shaft and the second shaft, wherein the first and second shafts rotate in different directions when the first shaft drives the first gear set and wherein the first and second shafts rotate in the same direction when the first shaft drives the second gear set;
- a differential that is driven by the second shaft, the differential having first and second differential output shafts;
- and
- a connection output shaft selectively coupled to the second differential output shaft, wherein the second differential output shaft rotates the connection output shaft when coupled and does not rotate the connection output shaft when not coupled.
