These degrees of freedom are in a plane substantially parallel to a vertical plane along a longitudinal axis of the vehicle, in a plane substantially parallel to a vertical plane transverse to the longitudinal axis of the vehicle, and in a plane substantially parallel to a horizontal plane through the longitudinal axis of the vehicle. Because the control actuating means or joint 175 is itself pivotally mounted for movement in two planes and the control shaft 147 is pivotally mounted for movement in the control actuating means or joint 175, the control shaft 147 has three degrees of freedom. Blade Amphibious All Terrain RC - YouTube 0:00 / 1:00 Let's Play! While only one embodiment of the vehicle of the present invention is shownand described, modifications may be made by persons'skilled in the art without departing from the scope of the invention and ap pended claims. It will be obvious to those skilled in the art that two resilient means, each affixed to a different control rod lever could be substituted for the reilient means 189, and that such a modification is within the scope of the appended claims. The sprocket wheel 129 thereby contacts the chain 131 and applies a constant force against the chain in a direction substantially transverse thereto, hence subjecting the chain to tensioning forces. 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. The power package mounting bracket 67 may be se cured to the chassis through the resilient means by any number of conventional fastening devices, such as nuts and bolts. An added safety feature is the units ability to float. At least two spaced apart chassis side rails 33,35 are located interior to the chassis 3 disposed along opposite longitudinal sides, and extending substantially the entire length of the chassis 3.

The vehicle may be also steered in the reverse direction by pivoting the control shaft in a generally horizontal plane without removing the control shaftl47 from one of the notches 161 in which it is located. Referring to FIGS. A resilient means 189 connected to both the first and second control rod levers 181, is biased to produce a force which tends to resist movement of the first control rod lever 181 in a counter-clockwise direction and the second control rod lever 185 in a clockwise direction as viewed in FIG. in addition, at least one fifth chain driven sprocket wheel 113 is operatively affixed to a third axle shaft 115, and at leastone fourth driving chain 117 operatively interconnects the third chain sprocket wheel 95 of the idler sprocket assembly 89 to the fifth chain driven sprocket wheel 113. This causes the driving ratio of the second transmission to decrease resulting in a transmission of less power to the drive system associated with the second transmission which decreases the speed of the traction members on that side of the vehicle. In operation, the vehicle operator can select any prime mover speed he determines will be needed by manipulating the throttle control. Amphibious Ultimate Terrain Vehicle.
