Embodiment Construction

[0041] Referring now to the drawings, wherein like reference numerals illustrate corresponding or like elements throughout the several views. figure 1 is a schematic diagram of one embodiment of a drive system incorporating a two-way overrunning clutch assembly 10 according to one embodiment of the present invention. The drive system includes a transmission 12 , a main drive shaft 14 , a main differential 16 , and first and second drive shafts 18 , 12 driving main wheels 22 .

[0042] The drive system also includes a secondary drive shaft 24 rotatably connected to the two-way overrunning clutch assembly 10 by any conventional means known to those skilled in the art, such as a splined connection. The two-way overrunning clutch assembly 10 in turn rotatably drives two secondary driven shafts 26 , 28 which are attached to wheels 30 .

[0043] The details of the two-way overrunning clutch assembly 10 will be compared to Figures 2 to 12B to describe. figure 2 is a perspective ...

Abstract

A bi-directional overrunning clutch assembly for engaging secondary driven shafts in a four wheel drive vehicle. The assembly includes a differential housing with a pinion input gear rotatably disposed within it that is engaged to a drive shaft. A bi-directional overrunning clutch housing is engaged to the pinion gear. A roll cage assembly is located inside the clutch housing. A pair of hubs are positioned within the roll cage assembly and connected to the secondary driven shafts. An electromagnetic system controls indexes the roll cage in a first direction relative to the clutch housing using a first indexing device for coupling the secondary drive shaft to the secondary driven axles when four-wheel drive is needed, and in an opposite direction using a second indexing device when an engine braking condition is needed. A spring assembly is preferably used to bias the roll cage back to a neutral position.

Description

[0001] related application [0002] This application is a non-provisional US patent application claiming priority to US Provisional Patent Application No. 61 / 783,125, filed March 14, 2013, which is incorporated herein by reference in its entirety. technical field [0003] This invention relates to clutches, and more particularly, to an electromechanical two-way overrunning clutch for providing four-wheel drive capability. Background technique [0004] The increased demand for off-road and all-terrain vehicles in recent years has led to a tremendous development of these types of vehicles. Much of the development revolves around making vehicles more adaptable to changing road conditions such as dirt, hard and gravel roads. As road terrain changes, it is desirable to alter the vehicle's drive capabilities to more efficiently negotiate the new terrain. Previous four-wheel drive and all-terrain vehicles were cumbersome because they required the operator to manually engage or di...
