摘要:
An all terrain vehicle with a foot-shifted manual transmission and a full platform-style footrest. The all terrain vehicle has a chassis carrying a straddle-type seat which is sufficiently narrow to be straddled by a rider. A laterally extending footrest is provided on each side of the chassis. The manual transmission includes a foot-operable shift lever located on one side of the chassis adjacent the footrest for shifting the transmission among a plurality of forward gears. The footrest is generally rectangular, having generally horizontal heel and toe portions, and the shift lever is positioned at approximately the same height as the heel portion. The toe portion is positioned lower than the heel portion, permitting a rider to depress the shift lever to a position lower than the heel portion of the footrest to downshift the transmission, and permitting the rider to insert his toe in between the toe portion of the footrest and the shifting lever to move the lever upwards to upshift the transmission. The platform is configured and arranged so as to prevent a toe of a rider's shoe from extending therethrough, however, thus providing full protection of the foot from below. The footrest includes a cleat formed integrally with the platform, the cleat having an upper surface positioned higher than the heel portion of the footrest. The cleat defines the forward edge of the heel portion and the rearward edge of the toe portion of the footrest, provides good foot heel location on the footrest and provides an edge about which the rider's foot may pivot during shifting.

A frame for an ATV comprises a support module with a central opening defining an engine receiving space. The support module includes a first frame member and a second frame member with at least one cross member extending between the first and second frame members. At least a portion of the support module, which includes one of the frame members and the at least one cross member, consists essentially of a single beam. The single beam may be considered a modular central beam of the frame.

The present invention concerns a method for designing and manufacturing a snowmobile platform. The method entails designing and manufacturing a group of tunnel subassemblies, designing and manufacturing a group of engine cradle subassemblies, and designing and manufacturing a group of front suspension subassemblies. Next, one tunnel subassembly, one engine cradle subassembly, and one front suspension subassembly are selected from each respective group. Then, the tunnel subassembly is connected to the engine cradle subassembly at a rear portion thereof. Finally, the front suspension subassembly is connected to the engine cradle subassembly at a front portion thereof to create the snowmobile platform. The present invention also concerns a snowmobile platform constructed according to this method, which combines, among other elements, a tunnel subassembly, an engine cradle subassembly, and a front suspension subassembly.

A frame for an all terrain vehicle (ATV). The frame includes a bottom frame portion which has one or more bottom plates. Each of these plates is a sheet metal stamping with precision located mounting holes stamped into it for mounting vehicle components. The plates are secured to a pair of elongated reinforcing members oriented generally horizontally and generally parallel to one another along the length of the bottom frame portion. The bottom plates are of a length and width sufficient to shield a substantial portion of an engine and/or transmission mounted to the frame. The frame also includes a top frame portion and several structural support members supporting the top frame portion with respect to the bottom frame portion. Preferably at least some of the structural support members supporting the top frame portion with respect to the bottom frame portion are sheet metal stampings. In one preferred embodiment, one of the structural support members is a portion of the ATV's transmission.

A system reduces the amount of work exerted by an ATV operator to change transmission gears. The system includes a foot lever assembly with a mechanical portion, such as a mechanical linkage, attached to an automated portion, such as an electrical switch. When the ATV operator applies a predetermined amount of force to the foot lever assembly, a clutch assembly and a gear box are actuated in a single motion, assisted by the automated portion of the foot lever assembly. Thus, the operator is able to exert less work in order to change the gears.

An all terrain vehicle (ATV) with a dual hydraulic brake system. The brake system includes a first master cylinder, a pair of front hydraulic brake units, each one being associated with one of the ATV's front wheels, a rear brake unit associated with the ATV's rear wheels, a hand-operable brake lever mounted to the handlebars and operatively connected to the first master cylinder, and hydraulic linking the first master cylinder to the brake units so that when the brake lever actuates the first master cylinder brakes are applied to both the front and the back wheels of the ATV. A second master cylinder is connected to a second hand or foot-operable brake lever carried by the chassis near one of the footrests. Hydraulic connections link the second master cylinder to only the rear brake unit so that operation of the second brake lever actuates only the rear brake. The rear brake unit preferably is a disc brake that includes a caliper body and a stepped piston disposed within a stepped bore formed in the caliper body. The stepped piston and the stepped bore together defining two separate hydraulic fluid chambers. The first master cylinder is connected to one of the hydraulic fluid chambers and the second master cylinder is connected to the other hydraulic fluid chamber so that the piston can be actuated independently by either master cylinder, thus permitting the rear brake to be applied without activating the front brakes of the ATV.

An inlet grate cleaning system for a water jet propulsion system to be used in a watercraft. The water jet propulsion system has a water passage, the water passage has an inlet and the inlet has a forward area and a rearward area with respect to the watercraft. The inlet grate cleaning system comprises a pump and at least one water intake fluidly connected to the pump. At least one water outlet is also fluidly connected to the pump. The pump is adapted for pumping water from the at least one water intake to the at least one water outlet to create at least one jet of water. The at least one water outlet is positioned so as to direct the at least one jet of water toward an inlet grate.
