Abstract: A power transfer assembly for an engine is provided. The power transfer assembly includes a first flywheel coupled to a crankshaft of the engine. The power transfer assembly includes a second flywheel selectively coupled to the first flywheel. The power transfer assembly also includes a first transmission unit coupled to the first flywheel and the second flywheel. The first transmission unit is adapted to selectively transfer mechanical power between the first flywheel and the second flywheel. The power transfer assembly further includes a second transmission unit coupled to the first transmission unit, the second flywheel, and an engine accessory. The second transmission unit is adapted to selectively transfer mechanical power between any one of the first transmission unit and the second flywheel, and the engine accessory.

Abstract: A cost configurable drive system for machines having dual/tandem axle drive systems employs a split hystat power system. The system performance can be easily adjusted by the removal or installation of a planetary gear set and a clutch box. In this way, the system is configurable with components removed or substituted to allow for a less capable but lower cost offering, while allowing for very simple upgrade to a fully capable system.
Abstract translation: 具有双/串联轴驱动系统的机器的成本可配置驱动系统采用分体式hystat电源系统。 可以通过拆卸或安装行星齿轮组和离合器箱来轻松调整系统性能。 以这种方式，系统可配置，删除或替换组件以允许较低能力但较低成本的产品，同时允许非常简单的升级到完全功能的系统。

Abstract: A hybrid engine assembly may include an engine having a crankshaft, a supplemental shaft mechanically coupled to the crankshaft, a flywheel energy storage assembly, and an auxiliary device. A flywheel clutch may selectively couple the flywheel assembly to the crankshaft. The assembly may be selectively operated in an engine restart mode by directly coupling the flywheel energy storage assembly to the crankshaft prior to starting the engine, and in an auxiliary power mode by directly coupling the flywheel energy storage assembly to the auxiliary device.
