Power transfer system
Embodiments relate to systems and methods for transferring power from a vehicle drive train to a hydraulic pump. One aspect of the present invention provides system including a torque converter; a torque converter hub connected to at least the torque converter; and a synchronous drive system coupled to at least the torque converter.
1 . A system comprising:
a torque converter;
a torque converter hub connected to at least the torque converter; and
a synchronous drive system coupled to at least the torque converter.
2 . The system of claim 1 wherein the synchronous drive system comprises a first synchronous pulley connected to at least the torque converter.
3 . The system of claim 2 further comprising an interface sleeve connected to at least one of the first synchronous pulley, the torque device and the torque converter hub.
4 . The system of claim 2 wherein the synchronous drive system further comprises a second synchronous pulley.
5 . The system of claim 5 further comprising a hydraulic pump shaft connected to the second synchronous pulley.
6 . The system of claim 4 further comprising a synchronous belt rotatably coupling the first synchronous pulley and the second synchronous pulley.
7 . The system of claim 6 further comprising a housing containing at least the synchronous belt, the first synchronous pulley and the second synchronous pulley.
8 . A system for transferring power from a vehicle drive system to a vehicle fluid power system, the system comprising:
a power torque converter connected to the vehicle drive system;
a torque converter hub connected to at least the power torque converter; and
a synchronous drive system coupled to at least the power torque converter, whereby power is transferred between at least the vehicle drive system and the vehicle fluid power system.
9 . The system of claim 1 further wherein the synchronous drive system comprises a first synchronous pulley connected to at least the power torque converter.
10 . The system of claim 9 further comprising an interface sleeve connected vehicle drive system and at least one of the first synchronous pulley, the power torque device and the torque converter hub.
11 . The system of claim 10 wherein the synchronous drive system further comprises a second synchronous pulley.
12 . The system of claim 11 further comprising a hydraulic pump shaft connected to the second synchronous pulley and the vehicle fluid power system.
13 . The system of claim 12 further comprising a synchronous belt rotatably coupling the first synchronous pulley and the second synchronous pulley.
14 . The system of claim 13 further comprising a housing containing at least the synchronous belt, the first synchronous pulley and the second synchronous pulley.
