Austin Wolf, Plainfield; N: J; Application November 30, 19319,. Serial NoJ 306,844-
2 Claims.
This invention relates to. vehicle. driving. mech;- anism, the subject matter of thepresent application constituting. a. .continuationrin-part, of: my pending. application for paterna Sel'. No..v 713,584, led April 9, 1936., now Patent No.. `2,1.85,1o`k.issued December 26,. 19.39;. which in turn is. a'A continuation of my original application Ser. No. 612,057 filed May 18,1932.
Generically considered, it is the object of my present invention to provide a very simple, in eX- pensive and compact. arrangement .of the prime mover or engine and v power input and take-off shafts together with power transfer gearing, and incorporating means whereby, in the event of misalignment of the engine. crank shaft andthe power input shaft, a positive driving connection isl maintained with a ,smooth and uninterrupted now of power through the transfer gearing to the take-off shaft.
More particularly, it is the object of the invention y*to-'provide connecting means between the engine fly-wheel and theA power input shaft. embodyingv an Oldhamy type coupling provided with means which permits of substantially frictionless relative axial displacement between the fly-wheel and power input. shaft while maintaining. a positive. driving connection therebetween.
With the above and other objects in view, the invention consists in the improved vehicle drivingr mechanism and .the form, construction and vrelative arrangement of its several parts. as will hereinafter be more fullydescribed, illustrated in the accompanying drawing and subsequently incorporated in the subjoined claims.
In the drawing wherein IA have. illustrated one simple and practical embodiment of the invention, and in which similar reference characters designate corresponding parts throughout the several views:
Fig. 1 is a plan view, partly in section, illustrating one embodiment of the present invention.
Fig. 2 is a detail elevation of the male element of the coupling connection between the engine fly-wheel and power input shaft.
Fig. 3 is a detail horizontal sectional view of two of the coupling elements and Fig. 4 is a sectional view taken substantially on the line 4-4 of Fig. 3.
Referring in detail to the drawing, in Fig. 1 thereof, I have shown the present invention as employed in connection with a pair of laterally spaced apart internal combustion engines l0 and Il respectively, having their crank shafts disposed in axial alignment. To the opposed ends of the engine crank shafts, the drum type flywheels |12 and. I.3` respectively areA suitably fixed. These. fly-wheels` are; enclosed byv the housings. M and 1:5, respectively which areA rigidly secured to the ends-,of the.. respective origines` l0'. and tl...
rlihe fly-wheel. housings. Illy and t5 are rigidly connected with each. .other at. their inner open sides by an intermediate; housing; member. t6, in which power input: shafts l1. and [18 respectively are rotatably' supported in suitahleant-friotion bearings. Upon the. inner end. portion. of. each of: these; shafts, a power transferv gear t9 and12il respectively is. keyed or otherwise secu-relyxed. These. gears are in .constant meshwith diametrically oppositey sides of the. gear 2l fixed; upon the inner end. of the.; power take-off shaft 22. which is journalled in suitable. anti-friction. bea-rings. carried by the intermediate housing member I6.
The outer endsot the power-input shafts l1 and 1.8: Aare connected'A in; power transmitting. relation with the respective engine crank shaftsby means of. flexible coupling vdevices arranged withinthe drum shaped ily-wheels i2 and L31 respectively. Since; these couplings. are of. identically the-same construction, the following descriptionY of one of said couplings will suicefor both.
Preferably, inthe interest of simplicity and compactness in4 the arrangement of mechanical elements, I prefer to use power transmitting-couplings of the Oldham type, modified in the manner to be presently described in order to obtain substantially frictionless. relative movement. between the complementary parts thereof.. As is herein. shown, each coupling includes` a4 member or disk 2.3 securely -xed tothe inner faceof the end wall of. the fly-wheel in-y concentric relation therewith. This, member is provided with adia.- rnetrically extending groove or channel, 2.4.
A similar coupling member or disk 25Y is also fixed to the opposed end of the power input shaft and is likewise provided with a diametrically extending groove or channel 2li. Between members 23 and 25, a male coupling member or disk 21 is interposed. The opposite side faces of this disk are provided with diametrically extending ribs 28 and 2S respectively disposed at right angles to each other. One of these ribs is movably positioned in the groove or channel 24 of the coupling member 23 on the engine ily-wheel while the other of said ribs is engaged in the groove or channel of the coupling member 25 on the power input shaft.
In order to eliminate friction as far as possible in the relative movement between said coupling members, I provide, in the opposite end portions of each of the grooves or channels 24 and 26, two series of anti-friction rollers 30, the rollers in each series being distributed between the side walls of the channel and the opposing faces of the ribs 28 and 29 in radially spaced relation to each other. The individual rollers are held in such spaced relationship by mounting the same in the opposite end portions of a sheet metal cage member 3|. These anti-friction units are of slightly less length than the respective grooves and have bodily longitudinal movement therein. v
In order to prevent outward radial movement of the cage member and anti-friction rollers from the channels 24 and 2S, a metal band 32 is suitably secured upon the periphery of each of the coupling members 23 and 25, it being understood that the edge of this band is suitably recessed to permit movement of the rib on the.
Any suitable means may be provided for lubricatinglthe above described couplings, such for instancaasthe lubricant supply. ducts or passages. 33 and 34 respectively in the crank shafts of the engines lll andll. Ay suitable lubricant may also be supplied to the power .transfer gearing through the pipe connection 35 with the intermediate housing member I6.
, From the foregoing description considered in connection `with the accompanying drawing, it will be appreciated that Ilhave provided a very simple, inexpensive and compact arrangement which is particularly advantageous in av driving mechanism for motor vehicles and insures a smooth, continuous and uninterrupted transfer of power from the engine crank shaft to the take-off shaft 22, which is suitably connected through the change speed transmission with-the driving axle differential. By the provision of the improved coupling means'between the engine crank shaft and power input shaft as above described, displacement of the crank shaft axis relative to the power input shaft, due to wear in the bearings, or other causes, will not result in binding and possible mutilation or stripping of the teeth of the power transfer gears. Notwithstanding such axial displacement 'between the crank shaft and thepower input shaft, there will be maintained, in effect, a substantially rigid connection between said shafts and a continuous uninterrupted transfer of power from the engine crank shaft to the take-off shaft 22. Of course, while I have herein referred to an adaptation of my present invention in connection with a pair of laterally spaced engines, it will be apparent that the invention may also be used in connection with a single engineer prime mover. When' access is required to the parts of the power transfer mechanism, such access can readily be obtained by simply disconnecting the intermediate housing I6 so that said housing together with the power input and output shafts and the gearing can be removed as a single unit.
In the foregoing description and the accompanying drawing, I have disclosed a simple and practical embodiment of the invention, but it is to be understood that the combination and relative arrangement of the various mechanical parts is susceptible of more or less modification. Accordingly, my invention is not to be limited in these particulars, since it may also be exemplified in various other alternative structural forms, not herein specifically disclosed, but which may be fairly comprehended as within the spirit and scope of the appended claims.
I claim:
l. In combination with driving and driven shafts, coupling members fixed to opposed ends lpling members,V anti-friction members of said shafts and provided with diametrically extending grooves in their opposed faces extendingat right angles to each other, an intermediate coupling member having diametrically extending ribs onA its opposite faces respectively positioned in the grooves of said first named couinterposed between the walls of said grooves and the ribs on said intermediate coupling member, and means `for. retainingsaid anti-friction members in said grooves While permitting of relative .radial movement of said ribs beyond the end of said grooves, said means comprising a band secured upon the periphery of each of said first named coupling members and having diametrically opposed recesses through which said ribs are movable. l l
