I attain these objects by the constructions Between and adjacent to the sleeve F and the 7 30 shown in the accompanying drawings. differential part I is journaled upon the axle Figure 1 is a plan view of my invention. E two body-supporting bearings L and M, Figs. 2 and 3 are sectional views showing the which are rigidly or directly connected todriving-axle and its connecting parts.

The reach D is a detail of same. pivotally or iiexiblyconnected to M by means 40 Like parts are represented by similar letof a joint D, or it might be pivoted or jourters of reference in the several views. naled over or to the casing O. The body- In the construction of my gear I employ supporting springsarepreferably attached by the usual vehicle-wheels A, A A and A, means of a pivoted piece L, Fig. 4, and either the guiding-axle B, and reaches or side bars attached to the corner-bearings or their con- 45 C and D. The reaches are preferably connections.
nected to the guiding-axle B, as shown in The motor P is directly or rigidly connect- Fig. 5, in which they are provided with a reed to L and provided with journals P and P duced extension O, which passes through the in which a driving-shaft P is journaled, as soft-rubber washers O and metal ring O shown by the dotted lines in Fig. 2, and is provided with a pinion P, which meshes with a gear K. While I have shown an electric motor, yet another power might be utilized, or instead of the motor a framework only could be provided and the shaft P receive its power from another source. The reach C, Fig. 4, is pivoted to the motor P at its forward end and has an extension 0', which passes under the motor and is connected to L by means of springs G and This reach could, however, be rigidly connected to the forward end of the motor or on L, or the pivotal connection could be at the rear and the springs in front and accomplish the same results. Thus the motor is preferably spring-supported and permitted to vibrate around the driving-axle by reason of the corner-bearings. The motor pivotal or supporting points act also as body-supporting bearings, which are preferably fitted with antifriction-bearings, as shown. The flexible sidebar' connections to the guiding-axle and the pivotal connections at the driving-axle permit the desired flexibility.
In Fig. 4 I have shown by dotted lines the spring G which can be attached to the bodysill, and thereby dispense with the use of the side-bar support for the motor.
In Figs. 6 and 7 the body-supporting springs L and M are rigidly connected to the cornerbearings or motorpivot, thereby holdingthe motor in working position without the use of side bars. To assist in supporting and holding down the motor, cross-springs L and L may be provided. The corner-bearings are shown connected together by a bar or brace 0 the axle B being exposed and the motor bolted directly to the bar.
Referring again to Figs. 2 and 4, the gear K and pinion I are protected by the gearcase Q, which is preferably formed in halves, as indicated in Fig. 2, and is held together and in position by bolts Q, by means of arms Q and the journal P. This gear-cover is preferably made to cover only the periphery of the gear, as shown in Figs. 2 and 4.
The brake-leverRacts u pon the brake-band J through a bell-crank J and shaft J The motor acts as a support for the shaft J, which passes through the motor and between its field-pieces. Thus no additional fixtures are necessary for the brake mechanism, and all the working parts are formed in such a manner as to prevent displacement.
The motor-supporting reach might be located near the center of the gear and the other dispensed with or numerous other minor changes made without departing from the scope of the invention.
Having thus described my invention, I claim-- 1. The combination of a driving-axle and driving-wheels, one of said wheels being rigidly connected and the other journaled to said driving-axle, a differential adjacent to said journaled driving-wheel, a part of which is directly connected thereto, and body-supporting corner bearings rigidly connected to gether, a motor adjacent to said differential and rigidly connected to said corner-bearings, body-supporting springs rigidly connected to said corner-bearings, and a crossspring, whereby the motor is held in a normal working position, substantially as and for the purpose specified.
