As the actuating joint 175 pivots it causes the control rod levers 181, 185 to rotate through a horizontal plane. 8 is a front sectional view of the chassis taken along line 3-8 of FIG. LEARN MORE ABOUT THE ATLAS EV. 3. FIG. The lost motion means includes at least two spring loaded control levers each pivotally mounted at one end to the control actuating means. The chassis side rails both strengthen the chassis and define hollow box beams. For example, any number of prime movers such as Wankel, Otto cycle, Diesel cycle, Vapor power cycle engines or compound power plants incorporating a number of these cycles may be used. Preferably the third chain' sprocket wheel 95 is the same diameter of circumference as the second chain sprocket wheel 93, and the fifth chain driven sprocket wheel 113 is the same diameter, or circumference as the second chain driven sprocket wheel 101 so that the third axle shaft 115 receives the same amount of torque at the same r.p.m. Preferrably a resilient means 85 is located between the transmission mounting means 79 and the chassis side rails 33, 35 to further isolate the chassis from the hydrostatic transmissions 55, 57, thus, preventing vibrations in the chassis from reaching the transmissions and vibrations in the power package from reaching the chassis. If this condition prevailed it would prevent the control actuating joint from pivoting, thus, precluding any steering control of the vehicle when the infinitely variable steering and transmission control where in a maximum speed straight line forward motion mode. Sis a side view of the power package mounting bracket shown in FIG. 22. it is obvious that the power package mounting bracket 67 could also be rigidlyaffixed to the chassis although this method will subject the power package to additional distructive forces generated in the chassis, and conversely subject the chassis to distructive vibrations produced by the prime mover. 144.6) interior to the chassis 3. Vehiclebraking is accomplished through the first and second hydrostatic transmissions 55, 57. The opposite occurs when a command for a left turn is executed. The vehicle has a prime mover. power originating from secondary power source, Steering non-deflectable wheels; Steering endless tracks or the like by differentially driving ground-engaging elements on opposite vehicle sides by means of a single main power source using gearings with differential power outputs on opposite sides, e.g. A power package generally denoted as 53 (see FIGS. The effect is to prevent the vibrations produced in the chassis by any undulating terrain over which the vehicle travels from being transmitted to the prime mover 53 and hydrostatic transmissions 55, 57, and also to prevent prime mover vibrations from being transmitted to the chassis. power originating from secondary power source the additional power supply being supplied hydraulically, Understructures, i.e. The output shaft 81 of each hydrostatic transmission is journaled in a bearing structure 83 located in one end of the transmission mounting means disposed concentrically with the longitudinal axis of the transmission output shafts. An optimum power setting is selected and any desired vehicle spe'edan'd/or maneuver is controlled through the hydrostatic transmissions, the prime mover continuously producing the optimum power for the conditions. It will be obvious to those skilled in the art upon reading this specification that if endless flexible members, such as V-belts, or cog belts were substituted for the sprocket wheels of the chain drive system, that a pulley or sheave would replace the sprocket wheel 129 in the tensioning device 119 without departing from the precept of the claimed invention. An amphibious all terrain vehicle as defined in claim 8, wherein said chain tensioning devIces comprise in combination: a tensioning device mounting plate adapted to be secured to a structure; at least one elongated ratchet plate pivotally mounted at one of its ends to one end of said mounting plate; a plurality of ratchet teeth formed in an end of said ratchet plate opposite said end pivotally mounted to said mounting plate; a sprocket wheel adapted to operatively engage one of said chains to be tensioned rotatably mounted at said end of said ratchet plate contaning said ratchet teeth, and being disposed such that its sprocket teeth extend beyond the longitudinal edges of said elongated ratchet plate; first resilient means operatively associated with said ratchet plate biased to urge said ratchet plate to pivot about its pivot mounting in a direction generally toward said chain to be tensioned thereby causing said sprocket wheel to contact and apply a constant force against said chains to be tensioned thus keeping it in tension; a pawl adapted to engage said ratchet teeth pivotally mounted at one end to an end of said mounting plate opposite said end to which said ratchet plate is pivotally mounted, said pawl being disposed to prevent movement of said ratchet plate in a direction generally away from said chains to be tensioned; and second resilient means operatively associated with said pawl biased to urge said pawl to pivot about its pivot mounting in a direction toward said ratchet teeth to assure the engagement of said pawl with said ratchet teeth thereby holding said sprocket wheel in engagement with said chain to be tensioned against forces exerted by said chain on said sprocket wheel which would tend to cause said ratchet plate to pivot about its mounting in a direction generally away from said chain thus decreasing the force exerted on said chain by said ratchet wheel.
