Abstract
A driving power transfer apparatus for four-wheel drive automotive vehicles, has a primary output shaft for providing driving power for a rear propeller shaft and a secondary hollow output shaft for providing driving power for a front propeller shaft, and a drive power transfer, such as a fluid coupling, mounted on the secondary output shaft, for variably transmitting the driving power to the secondary output shaft from the primary output shaft. The secondary shaft is connected to a front propeller shaft via a splined sliding yoke.
Claims17
A driving power transfer apparatus, having a primary output shaft for providing driving power for a rear propeller shaft and a secondary hollow output shaft arranged in parallel with the primary output shaft for providing driving power for a front propeller shaft, for four-wheel drive automotive vehicles, said driving power transfer apparatus comprising:
- power transmission means operationally coupled to the primary output shaft for putting out driving power from the primary output shaft;
- a sliding yoke providing splined joint between the secondary output shaft and the front propeller shaft;
- and
- power transfer means, supported on the secondary output shaft, for variably transmitting said driving power to the secondary output shaft from said power transmitting means.
A driving power transfer apparatus, having a primary output shaft for providing driving power for a rear propeller shaft and a secondary hollow output shaft arranged in parallel with the primary output shaft for providing driving power for a front propeller shaft, for four-wheel drive automotive vehicles, said driving power transfer apparatus comprising:
- power transmission means, including at least a rotary member mounted for rotation on the secondary output shaft, for putting out driving power from the primary output shaft;
- power transfer means, mounted on the secondary output shaft, for variably transmitting said driving power to the secondary output shaft from said power transmitting means;
- and
- lubrication means for lubricating an interface between said rotary member and the secondary output shaft.
