A lubricant is contained in a portion of the vehicle chassis structure to lubricate the chain drive system as it passes therethrough.

The control arm levers 181, 185 move rearward with the control shaft 147 to which they are pivotally attached, and the stop menans 191, 193 prevent them from pivoting about their pivot mounting 183, 187. As is best shown in FIG. 8. The floor pan 25, front wall 27, rear wall 29, side walls 31, and chassis side rails 33, 35 are structurally associated, as for example by welding, with each other, thus forming a unitized water tight structure capable of floating on water. A plurality of traction members, such as wheels or tracks, are operatively associated with these first and second series of drive axle shafts to support the vehicle on, and to enable it to translate relative to a surface. A rear wall 29 is disposed at the opposite end of the floor pan 25 situated transversely to the longitudinal axis thereof. Description of Prior Art The prior art amphibious all-terrain vehicles experience a number of drive system problems such as short chain drive system life due to a lack of lubrication, drive chains disengaging from their mating drive system components upon a sudden change in direction of the driving forces applied to the drive system by the transmissions, inadequate driving torque due to low, or no multiplication of the engine torque as it is transmitted to the drive system from the transmissions, and failure of the engine and transmissions due to rigidly mounting them to the vehicle, thus subjecting them to the forces exerted on the vehicle as it translates over undulating terrain. 15 is a view from the side of the chassis showing a portion of the chain drive system. 13 de octubre de 2022 . Unlike most tracked vehicles that use brake and slew steering systems, or other steering methods that can . An added safety feature is the units ability to float.

The console 151 has an elongated slot 159 which is situated substantially parallel to the longitudinal direction of the chassis 3 and is adapted to slideably receive the vehicle operators control shaft 147. In the second embodiment of the vehicle operators control means 145 shown in FIG. FIG. 20). as the second axle shaft 103. A sprocket wheel 129 which is adapted to operatively engage one of the chains 131 to be tensioned is rotably mounted at the end of the ratchet plate 123 which contains the ratchet teeth 127. Although these features are described with reference to an amphibious all-terrain vehicle, they may be incorporated with a multitude of machines, or limited-terrain vehicles. An amphibious all-terrain vehicle which is capable of translating over and through essentially all forms of terrain and substantially any environment. 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. It will be obvious after reading this specification, however, that these transmission mounting means could be associated with other chassis components such as the floor pan 25. 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. 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. 1 and 2, preventing any lost motion in the first control rod lever 181.

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. DESCRIPTION OF THE INVENTION With reference to FIGS. However, the transmission ratio selector device 177 is already in its most forward position corresponding to a maximum forward speed, it cannot be further displaced forward. 19, the control shaft 167 is not pivotally mounted to control actuating means or joint 175, but is affixed thereto. blade amphibious all terrain instructions. Attachable optionally to the pontoon hull (2) are earth-moving, wetland-clearing, wetland-farming, snow-moving . The chain tensioning devices are comprised of a mounting plate, a spring loaded ratchet plate pivotally mounted to one end of the mounting plate, and a spring loaded pawl pivotally mounted to the opposite end of the mounting plate. FIG. It's one of the craziest vehicles we've driven. 5. 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. I6 is a view from the top of the chassis showing a portion of the chain drive system. Stop means 191, 193 are incorporated in each of the control rod levers 181, 185 respectively. FIG. 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. Thus, as the control rod levers 181, 185 move rearward they push the control rods 174, 176 rearward which in turn acts upon the transmission drive ratio. Polaris makes a range of outdoor engine equipped vehicles such as quads, snowmobiles and amphibious all-terrain rigs.

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. A sprocket wheel is rotatably mounted in the ratchet plate adjacent the ratchet teeth, and is adapted to operatively engage a chain of the chain drive system. Rugged Side-by-Side Series.
