Original No. 1,329,319, dated January 27, 1920, Serial No. 214,230, filed January 28, 1918. Application for reissue led April 16, 1923. Serial No. 632,583.
To all whom it may concern Be it known that I, ARTHUR F. BAKER, a citizen of the United States, residin at Oakland, county of Alameda, State of ali- 5 ornia, and formerly of Sedi-o Woolley, in
the county of Skagit and State of Washington, have invented a new and useful Improvement in Driving Mechanism for Motor' Cars, of which the following is a specification.
This invention relates to improvements in driving gears for motor vehicles, and the object of this improvement is to provide a unitary variable speed differential gearing that may be `used to take the place of the differential mechanism now in common use on motor vehicles and that willi either add an additional speed change orA permit the separate change speedgears now 1n common use on motor vehicles to be dispensed with if desired.
A further object is to provide a driving gear of this class that may be applied to a re-builty automobile or truck attachment 26 with comparatively few alterations and changes in the original driving mechanism of the automobile.
A still further object is to adapt the variable speed gear for use in connection with a 30 Worml drive vand to interpose the variable speed gear between the worm gear and the differential mechanism. y Y V A still vfurther object is to provide a driving gear of this nature that is completely housed, that may run in a bath vr of oil and one'that is equally well adaptedfor use in connection with new, or re'built motor Vehicles.
The invention consistsy in the novel con- 40 struction, of a change speed gear and the adaptation and vcombination of such gear with a differental mechanism and worm drive, as will be more clearly hereinafter described and claimed. A
In the drawings, Figure 1 is a view in vertical section of a driving gear constructed in accordance with this. invent-ion; Fig. '2
is a view in elevation, with certain parts broken away, of one side of the same as it might appear with the housing removed; Fig. 3 is a view in elevation with certain parts broken away of the side of the gear opposite to that shown in Fig. 2 as it might appear with the housing removed;
and Fig. 4.- is a view in elevation illustrating parts of the housing and gear shifting mechanism with the gears removed therefrom.
f In the present invention I have combined a differential of the type which employs a master ring or casing, with a planetary systemI of gears, the intermediate gears of the.
planetary system being connected to turn with, or journaled upon the master ring or casing of the differential, the power being communicated Afirst through one of the other gears of the planetary system and the turn- -ing' of the remaining gear of the planetary system being controlled, so as to thereby secure a change of speed in the turning of theshafts.
Referring to the drawings, throughout which, like reference numerals indicate like parts, the numerals 5 and 6 indicate the two parts of a fixed rear axle housing, the peripheral portion of which is shown yas roken away and 5 indicates an annularv shown, and whose inner end's'terminate in squared portions 11 that tit within the hubs 12 and '12 of bevel gears 13 and 14 respectively.
The bevel gears 13 and 14 are spaced apart and are normally adapted to mesh with other bevel gears 15 that are mounted on pins 16 on a spider 17.
The pins 16 of the spider 17 project outwardly through an annular casing 18 so that when the casing 18 is turned the bevel gears 15 will 'be turned therewith and will drive the gears 13 and 14 in the well known manner common to differential gears of the usual form of construction.
The bevel gears 13, 14, 15 and casing 18 together form-a differential of a common construction and areT illustrated as being typical of a suitable type of differential.
The 'differential casmg 18 is preferably constructed in two parts that are divided on the line of the pins 16 and are secured together b bolts or screws 19 so that'the difi'erentia can be assembled. This casing constitutes the master ring of the differential through which power is received and which revolves about the shafts or axles.
vThe differential casing 18 is formed with a transverse wall 20 that connects with a. symmetrically arranged sleeve 21 of lesser diameter than the casing 18 that forms a bearing for the hub portion 12 of the gear wheel 13 and that terminates in a shouldered journal member 22 that is positioned within the end of the axle housing 7 .and between which and the axle housing is interposed a ball-bearing 230i any suitable form of construction.
The differential casing or master ring 18 is provided on the end opposite the wall 20 with four outwardly directed lugs or flange members 24, andw'ith an inwardly directed flange or lip 25 that engages with the rear face of the bevel gear 14 andis spaced from the hub portion 12 by a packing ring or washer 26.
The lugs 24 are each provided with a removable bearing stu-d or pin 27 whereon is mounted a pinion 28, roller bearing 3() preferablyfbeing interposed between the pinions 28 and studs 27. These pinions 28 constitute the intermediate gears of the planetary system.
The outer ends of the studs 27 are reduced in diameter as at 31, and threaded for the reception of nuts 32, and the outer end of all of such studs are connected with each other by a rigid annular ring 33 that forms a brace and support for the outer' ends of the studs.
The pinions 28 are adapted to mesh with a central gear wheel 34 that is secured to an annular plate 35 by bolts 36. This gear 34 is the central or inner gear of the planetary system.
The plate 35 is provided with inwardly directed hub portion 37 that ,extends over the outer end of the hub portion 12 and the inner gear 34 is spaced from the hub portion 12 by a ball bearing 38 that eo-operates w-ith the hub portion 37 in forming a journal upon which the disk 35 may rotate. f
The disk 35 is also provided with an out- `wardly directed hub portion 4() that prolspaced interfitting members 51 on a shift- 'able clutch ring 52, the arrangement being such that the clutch ring will be caused to rotate with the ring gear 48 but may be moved sidewise with respect thereto.
The disk 35 is provided at a point opposite the ring a2 with a plurality of slots or recesses 53 into which the members 51 may be projected to lock the ring gear 48 to the disk 35 and the fixed housing part 5 is provided with a plurality of similar recesses 54 that are formed between lugs 55 and are adapted for the reception of lugs 56 on the side of the clutch ring 52 opposite the mem- 'Y bers 51 to lock the ring to the fixed housing and prevent rotation of the ring gear 48.
The clutch ring 52 is provided with an integral grooved shifter collar 57 within which are disposed two oppo'sitely arranged shifter elements58 that 'are connected by pins 60 with the ends of two curved shifter varms 61 that extend to and are rigidly secured on a stub shaft 62 that may be journaled in any convenient manner and connectedwith suitable devices whereby it may be oscillated to shift 'the ring 52 sidewise and selectively lock the ring gear to the disk 35 or to the fixed housing 5 or to release the ring gear from both the disk 35 and housing 5 thereby affording a neutral position.
The worm gear 45 is provided at a plurality of points with recesses 63 that serve as housings for compression springs 64` the inner ends of which are in engagement with stops 65 that are adjustably supported by screws 66'that are provided with lock nuts 67. The compressive force of the springs may be varied in an obvious manner justing the"` screws 66.
The outer ends of the springs are disposed around spindles 68 and bear against a ring 70 that frictionally engages the sides of the collar 57, the spindles 68 being fixedly secured to the ring 70.
The springs 64 exert a constant pressure against the ring 70 which pressure is transmitted to the shifter ring 52 andserves at all times to urge the shifter ring to the right as viewed in Fig. 1. This pressure serves to urge the lugs 56 into engagement with the-fixed housing and also serves to take up the play of the ring 52 in all of'its operative positions.
When the shifter ring 52 is in the posifion shown in Fig. 1 the gear is in neutral. 1f the worm gear 45 is driven when the by ad- 4.roll on the fixed rin parts are in this position, the inner gear 34 will rotate the inions 28 which in turn will idl rotate the oosely mounted ring gear 48 an ring 52.
Where the clutch ring 52 is moved so that the members 51 engage within the slots 53 of the plate 35 the plate 35, ring gear 48, pinions 28 and inner gear 34 all rigidly locked together so that there will be no relative rotation between the several gears, and the casing -18 includin the differential proper will be rotated wit the worm gear 45 thereby forming a direct high speed drive, and, neglecting the action of the differential, rotating the axles 9 and 10 at the same speed as the worm gear 45. i
The low speed drive is obtained by shifting the clutch ring element 56 into engagement with the lugs 55 and thereby locking the ring gear 48 to the fixed housing 5.
When the ring gear 4 8 is locked .in a fixed position and the disk 35 is driven, the inner gear 34 will rotate the pinions 28 which will gear and carry the casing 18 with them 1n the same direction in which the inner gear 34 is rotated but at a much slower speed.
When the device is in use the housing `formed by the parts 5 and 6 may be lled with grease so that all ofthe gears and bearings Will be thoroughly lubricated.
It is obvious that changes in the form of construction of the various parts of this device may be resorted to within the scope of the following claims. I
