Abstract:
An electric drive configuration for a skid steered vehicle comprises; a pair of propulsion motors (74a, 74b), each with a motor shaft protruding from both ends of the motor and mounted on the same axis across the vehicle, each being coupled at the outer end to drive one of a pair of tracks or set of wheels of the skid steered vehicle; a control differential steer gear unit (72) positioned between the two propulsion motors and in driveable communication with the inner ends of the two motor shafts; and a steer motor (71) in driveable communication with the controlled differential (72), the steer motor (71) being controllable from zero speed giving straight line running in which both motor shafts are coupled to run at the same speed, to a range of speeds in both directions of rotation giving steering capability in both directions.
Abstract:
Differential reduction drives on opposite sides of a vehicle are steer driven by a pair of worm gears (110) meshed with worm wheels (111) inputting steering torque into each reduction drive. The worm gears are rotationally interconnected so that the steering torque applied to the reduction drives is respectively equal and opposite. The arrangement allows a simple steering control shaft (46) to receive steering control torque for normal turning and driving torque for propulsion drive-assisted pivot turning. A pivot turn brake (120), applied to the drive torque train, can make pivot turning precise.
Abstract:
A vehicle steering differential (10) includes a case (12) defining a chamber (76), an opening (78) on a transverse axis (36) communicating therewith, and a mounting surface (80) about the opening (78). An input pinion gear (14) and a bevel gear (18) driven by the pinion gear (14) are rotatably connected to within case (12) in right angle intermeshing relationship by a body (20) releasably secured to the mounting surface (80). A radial opening (82) is defined in the case (12), and a steering motor (16) has a shaft (88) that extends through the radial opening (82) into driving engagement with the pinion gear (14), with the body (20) supporting the steering motor (16). The body (20) includes an arm (110) and a collar (122) releasably secured to the arm (110) for supporting the steering motor (16).

Said spring device includes at least one leaf spring having a constricted section in a central region of the leaf spring, wherein surfaces of said at least one leaf spring neighboring said constricted section are shaped convex. Such convex surfaces may have a parabolic contour.
Abstract:
A drive configuration for a skid steered vehicle incorporates a controlled differential for use in exercising steering control of the vehicle, comprising a compound planetary gear set (8) coupling two shafts (7a, 7b). Respective sun gears (10a) and (10b) turn with the shafts and mesh with compound planet gears (12) in a common planet carrier (13), the ratios of the number of gear teeth between each sun gear and the respective gears (14a) or (14b) of the compound planets being unequal so that when the planet carrier is stationary the two shafts are coupled through the differential to turn together in the same sense but with a speed difference, and controlled rotation of the planet carrier varies the speed difference between the shafts in accordance with the sense and speed of rotation of the planet carrier.

Abstract:
A multiple input, dual output differential motor transmission device (141, 142) incorporates a sun gear device (12) having first and second sun gears (12a, 12b) fixedly connected to each other whereby the first and second sun gears (12a, 12b) rotate together along a common axis of rotation; first and second ring gear devices (20c, 20d) having first and second ring gears (20a, 20b), respectively; and first and second sets of planetary gears (21a-21f). The first set (21a-21c) is interengaged between the first sun (12a) and ring (20a) gears, while the second set (21d-21f) is interengaged between the second sun (12b) and ring (20b) gears. The first sun (12a) and ring (20a) gears are concentrically and independently rotatable relative to each other with the first set of planetary gears (21a-21c) inter-engaged therebetween. The second sun (12b) and ring (20b) gears are concentrically and independently rotatable relative to each other with the second set of planetary gears (21d-21f) interengaged therebetween. Rotation of at least one of the first and second sun gears (12a, 12b) together, the first ring gear (21a) and the second ring gear (21b) generates at least one of rotational and revolving movement of a corresponding one of the first (21a-21c) and second (21d-21f) sets of planetary gears.
