FIG. Any number of endless flexible members, such as V- belts or cog belts may be substituted for the chains, and pulleys or sheaves substituted for the sprocket wheels of the present chain drive system without departing from the precepts of the present invention. With reference to FlGS. I l is a front view of the transmission mounting means shown in FIG. This causes the driving ratio of the first transmission to increase resulting in a transmission of more power to the drive system associated with the first transmission which increases the speed of the traction members on that side of the vehicle. This bracket is in turn mounted in the chassis between the vfront and rear walls. with twin-differential or epicyclic gears differential power outputs being effected by additional power supply to one side, e.g. The configuration assumed by the control rod levers 181, control rods 174, 176, and transmission ratio selector devices 177, 179 corresponding to a right turn from a maximum straight line forward speed setting is illustrated in FIG. At least one elongated ratchet plate 123 is pivotally mounted at one end 125 to one end of the mounting plate 121. The lost motion means includes at least two spring loaded control levers each pivotally mounted at one end to the control actuating means. Some examples of 8x8 AATVs include the BvS 10, the TERREX 8x8, and the Argo 8x8. to the right in this example. 2. 12'and 13, the automatic tensioning device 119 includes a mounting plate 121 which is adapted to be secured to a structure, for example, to the transmission mounting means 79, or chassis side rails 33, 35. Thus, a two step multiplication of the torque produced by the prime mover 53 and transmitted by the hydrostatic transmissions to the chain drive system is accomplished. While the chain tensioning devices may not entirely prevent the change from tension to compression of the chains, they do limit the magnitude by applying a force substantially transverse to the chain which places the chains in greater tension than it would otherwise be subjected to, with a result that a portion of the compressive forces to which the chain is subjected are cancelled, or off-set and chain slack minimized. It should be kept in mind that theprime mover throttle control means need not be manipulated, or changed to maneuver the vehicle. chassis frame on which a vehicle body may be mounted, Understructures, i.e. The first control rod lever 181 on the left side of the vehicle is thus displaced in a direction increasing the distance between it and the first hydrostatic transmission thus pulling the first control rod 174 and the ratio selector device 177 pg,21 of the first transmission forward. The opposite occurs when a command for a left run is executed. 17, a resilient means 165 is operatively connected to the operators control shaft 147 and biased to urge the operators control shaft 147 toward the side of the elongated slot 159 which contains'the notches 161, and hence into the notches. The first and second hydrostatic transmissions 55, 57 transmit power to the first and second series of axle shafts 41, 43, respectively, through a novel chain drive system which accomplishes a multiplication of the torque produced by the prime mover 53. A headlamp 21 may be situated in the body for night driving. A separate prime mover throttle control, not shown as almost any variety known to the art may be used, is provided to allow the vehicle operator to vary the power out-put of the prime mover. This effectively prevents any distortions of the chassis 3 produced by undulating terrain from reaching the transmissions 55, 57 through the transmission mounting means 79, the distortion being dissipated in a pivoting motion of the transmission mounting means 79 about the trunnion-type mounting configuration. Such a movement would be cuased by the tensioning forces exerted on the chain 131 by the driving forces supplied by the prime mover 53 to the various sprocket wheels of the drive system. As best shown in FllGS. Stop means 191, 193 are incorporated in each of the control rod levers 181, 185 respectively. 1-3.
