Abstract
A hybrid powertrain system for a vehicle includes an electric machine, a gear set mechanically connected with the electric machine, and a clutch mechanically coupled with at least one of a primary and secondary driveline assembly. The electric machine is configured to selectively provide motive power to at least one of the primary and secondary driveline assemblies. The gear set is configured to permit differential rotation between the primary and secondary driveline assemblies. The clutch is configured to selectively transfer torque between the primary and secondary driveline assemblies.
Claims16
A system for a vehicle comprising:
- a clutch coupled with at least one of a primary driveline assembly and secondary driveline assembly and configured to selectively transfer torque therebetween;
- an electric machine configured to selectively provide motive power to at least one of the primary driveline assembly and secondary driveline assembly;
- and
- a gear set connected with the electric machine and configured to permit differential rotation between the primary driveline assembly and secondary driveline assembly.
An automotive hybrid powertrain system for a vehicle including a primary driveline assembly and secondary driveline assembly, the system comprising:
- a power transfer box including an electric machine, a gear set mechanically connected with the electric machine, and a clutch mechanically coupled with at least one of the primary driveline assembly and secondary driveline assembly, the power transfer box being configured to selectively
- (i) provide motive power to at least one of the primary driveline assembly and secondary driveline assembly by converting electrical power to motive power,
- (ii) convert motive power received from at least one of the primary driveline assembly and secondary driveline assembly to electrical power,
- (iii) transfer torque between the secondary driveline assembly and primary driveline assembly via the clutch,
- (iv) transfer torque between the secondary driveline assembly and primary driveline assembly via the gear set, and
- (v) transfer torque between the electric machine and at least one of the primary driveline assembly and secondary driveline assembly via the gear set.
