To all whom it may concern:

Be it known that I, Jnssn G. Vmcmz'r, a citizen of the United States, and resident of Detroit, Wayne county, State of Michifiiun, have invented certam new and useful provements in Motor-Vehicles, of which the following is a specification.

This invention relates to motor vehicles, and particularly to the transmission or driving mechanism thereof.

One of the objects of the invention is to embody a reduction gearing in the hub of the driving wheel.

Another object of the invention is to provide a motor vehicle with a planetary gearin mounted in the driving wheel hub and ad equately housed therein.

Other objects of the invention will appear from the following description, taken in connection with the drawings which form I. art of this specification, and in which igure 1 is a vertical section through a motor vehicle axle and the wheel mounted thereon;

Fig. 2 is a section substantially on the line 2-2 of Fig. 1;

Fig. 3 is a section substantially on the line 3-3 of Fig. 1; and

Fig. 4 is an end view of the wheel.

Referring to the drawings, 10 represents one, of the vehicle supporting axles having a spindle dpart 11, upon which the wheel 12 is adapte to rotate. The'wheel comprises spokes 13 secured between the flanges 14 and 15 of the hub. The inner part 16, of the hub, besides having the flange 15, has an inwardly extending flange 17, 1n which the roller bearing 18 is mounted. This bearing also fits on the spindle 11, whereby the wheel is supported on the spindle. The flange 17 is also extended somewhat around the bearin 18 and makes a running joint with the spindle 11, as at 19.

The part 16 of the hub is also formed witha cylindrical portion 20, against which the inner ends of the spokes 13 abut, and secured to the outer end of this cylindrical portion, as by bolts 21, is a disk member 22, in the inner part of which is a bearing 23, also supported on the spindle 11 but separated somewhat from the bearing 18, as shown particularly in Fig. 1.

A spur ear 24 separates the bearings 18 and 23, a securing nut 25 holds the bearrugs and gear in lace on the spindle 11. The gear 24 is pre erably keyed to the spindle 11, as shown at 26.

The flange 14, hereinabove referred to forms a part of the outer end wall 27 of the hub, and this part of the hub is secured to the part 16 thereof by means of a series of bolts 28. Thus the parts 16 and 27 form inner and outer end walls, respectively, of the hub, and the disk member 22 forms an mtermediate wall, the wheel bearings being mounted in the inner end wall and the intermediate wall, as'hereinabove described.

The disk member 22 is formed with a series of holes 29, through which pass the shafts 30 and two pairs of planetary gears 31 and 32, these ears being shown as integral with theirs afts, and the ends of the shafts being mounted in bearings 33 and 34 1n the inner and outer end walls respectively. The gears 31 are mounted to constantly mesh with the gear 24, and the gears 32 constantly mesh wit a gear 35 mounted in bearings 37 in the outer end wall 27. This shaft 36 extends axially through the spindle 11 and is suitably connected with the motor through mechanism, not shown.

From the above description, it will be understood that the driving shaft 36 turns the gear. 35, which in turn transmits motion to the shaft 30, and by reason of the gear 31 meshing with the gear 24, the shaft 30 is bodily rotated around the axis of the spindle 11 and thereby carrying with it the entire wheel 12.

It will be seen that the flange 17 extends inwardly to a point adjacent the spindle 11, and the outer wall 27 completel incloses the gears at that end, so that lu ricant is easily retained in the casing thus formed within the hub and inclosing the gears.

Various modifications of the invention may be made without departing from the spirit thereof, and all such modifications and mechanical equivalents are intended to be included in the claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. In a motor vehicle, the combination with the supporting axle, of a wheel having a hub mounted on supporting bearings on said axle, gears in the hub connecting the wheel andanle, some of said gears being offa set from the wheel axis and being adapted to rotate with the wheel and about their own axes, and a driving shaft extending through the axle and connected to said gears.

2. In a motor vehicle, the combination with the supporting axle, of a wheel supported on bearings and adapted torotate thereon, gears mounted in the wheel to rotate therewith and on their own axes and connected to operate the wheel, and a driving shaft extending through the axle and connected to said gears.

3. In a motor vehicle, the combinationwith the supporting axle, of a wheel supported on bearings and adapted to rotate thereon, a gear secured to the axle, planetary gears carried b the wheel and in mesh wit said gear, an a driving shaft extending through the axle and connected to sai planetary gears. v

4. In a motor vehicle, the combination with the supporting axle, of a wheel supported on bearings and adapted to rotate thereon, planetary reduction gears connected to the axle and wheel, and a driving shaft extending through the axle and connected to operate the planetary gears.
