Embodiment Construction

[0029] The present invention herein improves upon the prior art compact full traction differential disclosed in above-referenced US Patent No. 6,783,476 and has a similar basic structure to the prior art differential. Therefore, first refer to Figure 1a and 1b , which shows two views of a complete spider gear assembly with only two sets of balance gears according to the first exemplary embodiment of the differential 10 according to the invention.

[0030] Housing 120 is preferably made of formed or cast metal and has only three openings, a first set of appropriate openings 121 aligned along first axis 125 for receiving respective inner ends of output shafts (not shown). , 122, and only a single further opening 126, which is rectangular and extends directly through the housing 120 and is centered perpendicular to the axis 125, thereby creating two what is considered in the art to receive The opening of the "window" of the combined gear pair.

[0031] Each of the two pairs o...

Abstract

An all-gear differential designed primarily for motor vehicle use, employing a ''cross-axis'' arrangement defined by a pair of helical ''side'' or ''S'' gears rotatable about a common first axis and mountable on respective opposite vehicle axles, and one or more pairs of ''balance'' or ''B'' gears rotatable about second axes orthogonal to the first axis. The B gears have helical central portions for meshing with the helical S gears, and have spur gear end portions for meshing with each other. The B / S helical gear tooth ratio between each balance gear and its respective side gear greater than 0.60 and preferably is about 0.75, and the B / S helical angle ratio between each balance gear and its respective side gear is less than 43 DEG / 47 DEG, more preferably is less than 40 DEG / 50 DEG and about 35 DEG / 55 DEG , and most preferably is about 27 DEG / 63 DEG .

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Patent Application No. 12 / 482,185, filed June 10, 2009, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to an all-gear differential designed primarily for use in motor vehicles for providing limited slippage of the vehicle's drive wheels; A helical "side" gear, referred to herein as the "S" gear, rotates about a common first axis, and one or more pairs of "balance" gears, referred to herein as the "B" gear, are connected to the rear axle housing The gears define such a differential of a "cross shaft" arrangement, each balance gear being rotatable about a second axis perpendicular to the first axis and having a helical central portion for meshing with the helical side gears and having for each other Engaging spur gear ends whereby each balance gear receives engine torque through its connection to the rear axl...
