Apparatus for selectively sharing the power of a multidrive unit vehicle
An apparatus for selectively sharing, towards separate users, the power of a multi-drive unit vehicle, includes a mechanical transmission, that connects propulsion units of the vehicle to at least one primary drive unit; a secondary power unit for service units, which is operatively positioned between the mechanical transmission and at least one service unit of the vehicle; as well as at least one of either a first or a second joint, that are mounted on the mechanical transmission on either side of the secondary power unit for service units and are switchable by operating suitable control means.
1. A vehicle, comprising:
a mechanical transmission, that connects a propulsion unit of the vehicle to a primary drive unit;
a secondary drive unit configured to supply power to a service unit of the vehicle, wherein the secondary drive unit is operatively positioned between the mechanical transmission and the service unit;
a first joint mounted between the mechanical transmission and the secondary drive unit;
a second joint mounted between the secondary drive unit and the service unit; and
a controller, operatively interfaced with the first joint and the second joint, configured to manage, in response to a failure of the primary drive unit, selectively sharing of power from the secondary drive unit to the propulsion unit and the service unit, using the first joint and the second joint.
2. The vehicle according to claim 1 , wherein the secondary drive unit is configured to generate power to be sent to the service unit.
3. The vehicle according to claim 2 , wherein the controller is configured to manage selectively sharing of power towards the service unit based on a correlation between requests for propelling power from the propulsion unit and efficiency curves characteristic of the primary drive unit and/or the secondary drive unit.
4. The vehicle according to claim 2 , wherein the secondary drive unit comprises an electric motor.
5. The vehicle according to claim 2 , wherein the secondary drive unit comprises a combustion engine.
6. The vehicle according to claim 1 , wherein at least one of the first joint and the second joint comprises a clutch.
7. The vehicle according to claim 1 , wherein the primary drive unit comprises an electric generator.
8. The vehicle according to claim 1 , further comprising a vehicle battery between the secondary drive unit and the service unit.
9. The vehicle according to claim 1 , wherein the controller is configured to manage selectively sharing of power towards the propulsion unit depending on priority requests for propelling power arriving from the propulsion unit.
10. The vehicle according to claim 1 , wherein the controller is configured to manage selectively sharing of power towards the propulsion unit based on priority requests for propelling power.
11. A method of manufacturing a vehicle, comprising:
connecting, via a mechanical transmission, a propulsion unit to a primary drive unit;
positioning a secondary drive unit between the mechanical transmission and a service unit;
configuring the secondary drive unit to supply power to the service unit;
mounting a first joint between the mechanical transmission and the secondary drive unit;
mounting a second joint between the secondary drive unit and the service unit; and
interfacing a controller with the first joint and the second joint, the controller being configured to manage, in response to a failure of the primary drive unit, selective sharing of power from the secondary drive unit to be the propulsion unit and said service unit using the first joint and the second joint.
12. The method according to claim 11 , wherein configuring the secondary drive unit to supply power to the service unit includes generating power to be sent to the service unit.
13. The method according to claim 12 , wherein interfacing said controller with the first joint and the second joint includes configuring the controller to manage selectively sharing of power towards the service unit based on a correlation between requests for propelling power from the propulsion unit and efficiency curves characteristic of the primary drive unit and/or the secondary drive unit.
14. The method according to claim 12 , wherein positioning the secondary drive unit includes positioning an electric motor between the mechanical transmission and the service unit.
15. The method according to claim 12 , wherein positioning the secondary drive unit includes positioning a combustion engine between the mechanical transmission and the service unit.
16. The method according to claim 11 , wherein at least one of mounting the first joint and mounting said second joint includes mounting a clutch.
17. The method according to claim 11 , wherein connecting the propulsion unit to the primary drive unit includes connecting the service unit to a vehicle battery.
18. The method according to claim 11 , wherein positioning the secondary drive unit includes positioning a vehicle battery between an electric generator and the service unit.
19. The method according to claim 11 , further comprising selectively sharing of power towards the propulsion unit depending on priority requests for propelling power arriving from the propulsion unit.
20. The method according to claim 11 , further comprising selectively sharing of power towards the propulsion unit based on priority requests for propelling power.
